Artificial intelligence (AI) in robotics defines new ways organizations can use machines to optimize operations. According to a McKinsey report, AI-powered automation could boost global productivity by up to 1.4% annually, with sectors like manufacturing, healthcare, and logistics seeing the most significant transformation.  However, integrating AI into robotics requires overcoming challenges related to data limitations and ethical concerns. Also, the lack of diverse datasets for domain-specific environments makes it difficult to train effective AI models for robotic applications.  In this post, we will explore how AI is transforming robotic automation, its applications, challenges, and future potential. We will also see how Encord can help address issues in developing scalable AI-based robotic systems. Difference between AI and Robotics Artificial Intelligence (AI) and robotics are different yet interconnected fields within engineering and technology. Robotics focuses on designing and building machines capable of performing physical tasks, while AI enables these machines to perceive, learn, and make intelligent decisions.  AI consists of algorithms that enable machines to analyze data, recognize patterns, and make decisions without explicit programming. It uses techniques like natural language processing (NLP) and computer vision (CV) to allow machines to perform complex tasks.  For instance, AI powers everyday technologies, such as Google's search algorithms, re-ranking systems, and conversational chatbots like Gemini and ChatGPT by OpenAI.  Robotics, however, focuses on designing, building, and operating programmable physical systems that can work independently or with minimal human assistance. These systems use sensors to gather information and may follow programmed instructions to move, pick up objects, or communicate. A line following robot The integration of AI with robotic systems helps them perceive their environment, plan actions, and control their physical components to achieve specific objectives, such as navigation, object manipulation, or autonomous decision-making. Why is AI Important for Robotics? AI-powered robotic systems can learn from data, recognize patterns, and make intelligent decisions without requiring repetitive programming. Here are some key benefits of using AI in robotics: Enhanced Autonomy and Decision-Making Traditional robots use rule-based programs that limit their flexibility and adaptability. AI-driven robots analyze their environment, assess different scenarios, and make real-time decisions without human intervention.  Improved Perception and Interaction AI improves a robot's ability to perceive and interact with its surroundings. NLP, CV, and sensor fusion enable robots to recognize objects, speech, and human emotions. For example, AI-powered service robots in healthcare can identify patients, understand spoken instructions, and detect emotions through facial expressions and tone of voice. Learning and Adaptation AI-based robotic systems can learn from experience using machine learning (ML) and deep learning (DL) technologies. They can analyze real-time data, identify patterns, and refine their actions over time.  Faster Data Processing The modern robotic system relies on sensors such as cameras, LiDAR, radar, and motion detectors to perceive their surroundings. Processing such diverse data types simultaneously is cumbersome. However, experts can use AI to speed up data processing and enable the robot to make real-time decisions.  Predictive Maintenance AI improves robotic reliability by detecting wear and tear and predicting potential failures to prevent unexpected breakdowns. This is important in high-demand environments like the manufacturing industry, where downtime can be costly.  How is AI Used in Robotics? While the discussion above highlights the benefits of AI in robotics, it does not yet clarify how robotic systems use AI algorithms to operate and execute complex tasks. The most common types of AI robots include:  AI-Driven Mobile Robots An AI-based mobile robot (AMR) navigates environments intelligently, using advanced sensors and algorithms to operate efficiently and safely. It can:  See and understand its surroundings using sensors like cameras, LiDAR, and radar, combined with CV algorithms to detect objects, recognize obstacles, and interpret their environment. Process and analyze data in real time to map out their surroundings, predict potential hazards, and adjust to changes as they move. Find the best path and navigate efficiently using AI-driven algorithms to plan routes, avoid obstacles, and move smoothly in dynamic spaces. Interact naturally with humans using AI-powered speech recognition, gesture detection, and other intuitive interfaces to collaborate safely and effectively. Mobile robots in a warehouse AMRs are highly valuable on the factory floor to improve workflow efficiency and productivity.  For example, in warehouse inventory management, an AMR can intelligently navigate through aisles, dynamically adjust its route to avoid obstacles and congestion, and autonomously transport goods.  Articulated Robotic Systems Articulated robotic systems (ARS), or robotic arms, are widely used in industrial settings for tasks like assembly, welding, painting, and material handling. They assist humans with heavy lifting and repetitive work to improve efficiency and safety. Articulated robot  Modern ARS uses AI to process sensor data, enabling real-time perception, decision-making, and precise task execution. AI algorithms help ARS interpret their operating environment, dynamically adjust movements, and optimize performance for specific applications like assembly lines or warehouse automation. Collaborative Robots Collaborative robots, or cobots, work safely alongside humans in shared workspaces. Unlike traditional robots that operate in isolated environments, cobots use AI-powered perception, ML, and real-time decision-making to adapt to dynamic human interactions. AI-driven computer vision helps cobots detect human movements, recognize objects, and adjust their actions accordingly. ML algorithms enable them to improve task execution over time by learning from human inputs and environmental feedback. NLP and gesture recognition allow cobots to understand commands and collaborate more intuitively with human workers. Cobots: Universal Robots (UR)  Universal Robots' UR Series is a good example of a cobot used in manufacturing. These cobots help with tasks like assembly, packaging, and quality inspection. They work alongside factory workers to improve efficiency and human-robot collaboration. AI-Powered Humanoid Robots AI-based humanoid robots replicate the human form, cognitive abilities, and behaviors. They integrate AI to perform completely autonomous tasks or collaborate with humans. These robotic systems combine mechanical structures with AI technologies like CV and NLP to interact with humans and provide assistance. Sophia at UN For example, Sophia is one of the most well-known AI-powered humanoid robots, developed by Hanson Robotics. Sophia engages with humans using advanced AI, facial recognition, and NLP. She can hold conversations, express emotions, and even learn from interactions.

Common examples include DeepLab and U-Net. DeepSort for Object Tracking: A tracking-by-detection model that tracks objects in real time by first detecting them and assigning a unique ID to each object. Reinforcement Learning for Adaptive Behavior RL enables robots to learn through trial and error by interacting with their environment. The robot receives feedback in the form of rewards for successful actions and penalties for undesirable outcomes. Popular RL frameworks used in robotics include:  Deep Q-Network (DQN): DQN uses DL to learn the Q-function. The technique allows agents to store their experiences in batches and use samples to train the neural network. Lifelong Federated Reinforcement Learning (LFRL): This architecture allows robots to continuously learn and adapt by sharing knowledge across a cloud-based system, enhancing navigation and task execution in dynamic environments. Q-learning: A model-free reinforcement learning algorithm that helps agents learn optimal policies through trial and error by updating Q-values based on rewards received from the environment. PPO (Proximal Policy Optimization): A reinforcement learning algorithm that balances exploration and exploitation by optimizing policies using a clipped objective function, ensuring stable and efficient learning. Multi-modal Models Multi-modal models combine data from sensors like cameras, LiDAR, microphones, and tactile sensors to enhance perception and decision-making. Integrating multiple sources of information helps robots develop a more comprehensive understanding of their environment. Examples of multimodal frameworks used in robotics include: Contrastive Language-Image Pretraining (CLIP): Helps robots understand visual and textual data together, enabling tasks like object recognition and natural language interaction. ImageBind: Aligns multiple modalities, including images, text, audio, and depth, allowing robots to perceive and reason about their surroundings holistically. Flamingo: A vision-language model that processes sequences of images and text, improving robotic perception in dynamic environments and enhancing human-robot communication. Challenges of Integrating AI in Robotics Advancements in AI are allowing robots to perceive their surroundings better, make real-time decisions, and interact with humans. However, integrating AI into robotic systems presents several challenges. Let’s briefly discuss each of them. Lack of Domain-specific Data: AI algorithms require a large amount of good quality data for training. However, acquiring domain-specific data is particularly challenging in specialized environments with unique constraints. For instance, data collection for surgical robots requires accessing diverse real-world medical data, which is difficult due to ethical concerns. Processing Diverse Data Formats: A robotic system often depends on various sensors that generate heterogeneous data types such as images, signals, video, audio, text, and other modalities. Combining these sensors' information into a cohesive AI system is complex. It requires advanced sensor fusion and processing techniques for accurate prediction and decision-making.  Data Annotation Complexity: High-quality multimodal datasets require precise labeling across different data types (images, LiDAR, audio). Manual annotation is time-consuming and expensive, while automated methods often struggle with accuracy. Learn how to use Encord Active to enhance data quality using end-to-end data preprocessing techniques.   How Encord Ensures High-Quality Data for Training AI Algorithms for Robotics Applications The discussion above highlights that developing reliable robotic systems requires extensive AI training to ensure optimal performance. However, effective AI training relies on high-quality data tailored to specific robotic applications.  Managing the vast volume and variety of data presents a significant challenge, necessitating the use of end-to-end data curation tools like Encord to streamline data annotation, organization, and quality control for more efficient AI model development for robotics.

Future of Robotics & AI AI and robotics together are driving transformative changes across various industries. Here are some key areas where these technologies are making a significant impact:  Edge and Cloud Computing Edge computing offers real-time data processing within robotic hardware, which is important for low-latency use cases such as autonomous navigation. Cloud computing provides vast data storage and powerful processors to process large amounts of data for AI model training. This allows robots to react quickly to their immediate surroundings and learn from large data sets. Smart Factories  AI-powered robots are transforming factories, which use automation, IoT, and AI-driven decision-making to optimize manufacturing, streamline workflows, and enhance the supply chain.  Unlike traditional factories that rely on fixed processes and human efforts, smart factories use interconnected machines, sensors, and real-time analytics to adapt to production needs dynamically. These systems enable predictive maintenance, optimization, and autonomous quality control. For example, Ocado’s robotic warehouse uses swarm intelligence to coordinate thousands of small robots for high-speed order fulfillment.  Swarm Robotics  Swarm robotics uses a group of robots to solve a complex task collaboratively. AI makes these swarms coordinate their movements, adapt to changing environments, and perform tasks like search and rescue, environmental monitoring, and agricultural automation.  SwarmFarm Robotics spraying pesticides  For example, SwarmFarm Robotics in Australia uses autonomous robots in precision agriculture. These robots work together to monitor crop health, spray pesticides, and plant seeds. Coordinating their actions allows them to cover large areas quickly and adapt to different field conditions. Space and Planetary Exploration  AI-powered robots play a crucial role in space exploration by navigating unknown terrains, conducting scientific experiments, and performing maintenance in harsh environments.

Consider a boxy robot nicknamed “Shakey” developed by Stanford Research Institute (SRI) in the 1960s. This robot was named “Shakey” for its trembling movements. It was the first robot that could perceive its surroundings and decide how to act on its own​.  Shakey Robot (Source) It could navigate hallways and figure out how to go around obstacles without human help. This machine was more than a curiosity. It was an early example of giving artificial intelligence a physical body. The development of Shakey marked a turning point as artificial intelligence (AI) was no longer confined to a computer, it was acting in the real world. The concept of Embodied AI began to gain momentum in the 1990s, inspired by Rodney Brooks's 1991 paper, "Intelligence without representation." In this work, Brooks challenged traditional AI approaches by proposing that intelligence can emerge from a robot's direct engagement with its environment, rather than relying on complex internal models. This marked a significant shift from earlier AI paradigms, which predominantly emphasized symbolic reasoning. Over the years, progress in machine learning, particularly in deep learning and reinforcement learning, has enabled robots to learn through trial and error to enhance their capabilities. Today, Embodied AI is evident in a wide range of applications, from industrial automation to self-driving cars, reshaping the way we interact with and perceive technology. Embodied AI is an AI inside a physical form. In simple terms, it is AI built into a tangible system (like a robot or self-driving car) that can sense and interact with its environment​. A modern day example of embodied AI in a humanoid form is Phoenix, a general-purpose humanoid robot developed by Sanctuary AI. Like Shakey, Phoenix is designed to interact with the physical world and make its own decisions. Phoenix benefits from decades of advances in sensors, actuators, and artificial intelligence. Phoenix - Machines that Work and Think Like People (Source) What is Embodied AI? Embodied AI is about creating AI systems that are not just computational but are part of physical robots. These robots can sense, act, and learn from their surroundings, much like humans do through touch, sight, and movement. What is Embodied AI? (Source) The idea comes from the "embodiment hypothesis," introduced by Linda Smith in 2005. This hypothesis says that thinking and learning are influenced by constant interactions between the body and the environment. It connects to earlier ideas from philosopher Maurice Merleau-Ponty, who wrote about how perception is central to understanding and how the body plays a key role in shaping that understanding. In practice, Embodied AI brings together areas like computer vision, environment modeling, and reinforcement learning to build systems that get better at tasks through experience. A good example is robotic vacuum cleaners Roomba. Roomba uses sensors to navigate its physical environment, detect obstacles, and learn the layout of a room and adjust its cleaning strategy based on the data it collects. This allows it to perform actions (cleaning) directly within its surroundings, which is a key characteristic of embodied AI. Roomba Robot (Source) How Physical Embodiment Enhances AI Giving AI a physical body, like a robot, can improve its ability to learn and solve problems. The main benefit is that an embodied AI can learn by trying things out in the real world, not just from preloaded data. For example, think about learning to walk. A computer simulation can try to figure out walking in theory, but a robot with legs will actually wobble, take steps, fall, and try again which enables it to learn a bit more each time. This is just like a child learning to walk by falling and getting back up, the robot improves its balance and movement through real-world experience. Physical feedback, like falling or staying upright, teaches the AI what works and what does not work. This kind of hands-on learning is only possible when the AI has a body to act with. Real-world interaction also makes AI more adaptable. When an AI can sense its surroundings, it isn’t limited to what it was programmed to expect, rather it can handle surprises and adjust. For example, a household robot learning to cook might drop a tomato, feel the mistake through touch sensors, and learn to grip more gently next time. If the kitchen layout changes, the robot can explore and update its understanding. Embodied AI also combines multiple senses, called multimodal learning, to better understand its environment. For example, a robot might use vision to see an object and touch to feel it, creating a richer understanding. A robotic arm assembling something doesn’t just rely on camera images, it also feels the resistance and weight of parts as it works. This combination of senses helps the AI develop an intuitive grasp of physical tasks. Even simple devices, like robotic vacuum cleaners, show the power of embodiment. They learn the layout of a room by bumping into walls and furniture, improving their cleaning path over time. This ability to learn through real-world interaction by using sight, sound, touch, and movement gives embodied AI a practical understanding that software-only AI can not achieve. It is the difference between knowing something in theory and truly understanding it through experience. Applications of Embodied AI Embodied AI has several applications across various industries and domains. Here are a few key applications of Embodied AI. Autonomous Warehouse Robots Warehouse robots are a popular application of embodied AI. These robots transform how goods are stored, sorted, and shipped in modern logistics and supply chain operations. These robots are designed to automate repetitive, time-consuming, and physically demanding tasks to improve efficiency, accuracy, and safety in warehouses. For example, Amazon uses robots (e.g. Digit) in its fulfillment centers to streamline the order-picking and packaging process. These robots are the example of embodied AI because they learn and operate through direct interaction with their physical environment. Embodied AI Robot Digit (Source) Digit relies on sensors, cameras, and actuators to perceive and interact with its surroundings. For example, Digit uses its legs and arms to move and manipulate objects. This physical interaction generates real-time feedback that allow the robots to learn from their actions such as adjusting its grip on an item or navigating around obstacles. The robots improve their performance through repeated practice. For example, Digit learns to walk and balance by experiencing different surfaces and adjusting its movements accordingly.  Inspection Robots  Spot robot from Boston Dynamics is designed for a variety of inspection and service tasks. Spot is a mobile robot and is adaptable to different environments such as office, home,  and outdoors such as construction sites, remote industrial facilities etc. With its four legs, Spot can navigate uneven terrain, stairs, and confined spaces that wheeled robots may struggle with. This makes it ideal for inspection tasks in challenging environments. Spot is equipped with camera, depth sensors, and microphone to gather environmental data. This allows it to perform tasks like detect structural damages, monitor environmental conditions, and even record high-definition video for remote diagnostics. While Spot can be operated remotely, it also has autonomous capabilities. It can patrol pre-defined routes, identify anomalies, and alert human operators in real time. Spot can learn from experience and adjust its behavior based on the environment. Spot Robot (Source) Autonomous Vehicles (Self-Driving Cars) Self-driving cars, developed by companies like Waymo, Tesla, and Cruise, use embodied AI  for decision-making and actuation systems to navigate complex road networks without human intervention. These vehicles use a combination of cameras, radar, and LiDAR to create detailed, real-time maps of their surroundings. AI algorithms process sensor data to detect pedestrians, other vehicles, and obstacles and allow the car to make quick decisions such as braking, accelerating, or changing lanes. Self-driving cars often communicate with cloud-based systems and other vehicles to update maps and learn from shared driving experiences which improve safety and efficiency over time. Vehicles uses Embodied AI from Wayve AI (Source) Service Robots in Hospitality and Retail Embodied AI is transforming the hospitality and retail industries by revolutionizing customer interaction. Robots like Pepper are automating service tasks and enhancing guest experiences. Robots like this serve as both information kiosks and interactive assistants. For example, the Pepper robot uses computer vision and NLP to understand and interact with customers. It can detect faces, interpret gestures, and process spoken language which allow it to provide personalized greetings and answer common questions. Paper is equipped with sensors such as depth cameras and LIDAR to navigate through complex indoor environments. In retail settings, it can lead customers to products or offer store information. In hotels, similar robots might be tasked with delivering room service or even handling luggage by autonomously moving through corridors and elevators. These service robots learn from interactions. For example, it may adjust its speech and gestures based on customer demographics or feedback. Pepper robot from SoftBank (Source) Humanoid Robots Figure 2 is a humanoid robot developed by Figure.ai that gives AI a tangible, interactive presence. Figure 2 integrates advanced sensory inputs, real-time processing, and physical actuation which enable it to interact naturally with its surroundings and humans. Its locomotion capabilities are supported by real-time feedback from sensors, such as cameras and inertial measurement units, enabling it for smooth and adaptive movement across different surfaces and around obstacles. The robot uses integrated computer vision systems to recognize and interpret its surroundings. Figure 2 uses NLP and emotion recognition to engage in conversational interactions. Figure can learn from experience and refine its responses and behavior based on accumulated data from its operating environment which make it efficient to act in a real-world environment to complete designated tasks. Figure 2 Robot (Source) Difference Between Embodied AI and Robotics Robotics is the field of engineering and science focused on designing, building, and operating robots which are physical machines that can perform tasks automatically or with minimal human help. These robots are used in areas like manufacturing, exploration, entertainment etc. The field includes the hardware, control systems, and programming needed to create and run these machines. Embodied AI, on the other hand, refers to AI systems built into physical robots, allowing them to sense, learn from, and interact with their environment through their physical form. Inspired by how humans and animals learn through sensory and physical experiences, Embodied AI focuses on the robot's ability to adapt and improve its behavior using techniques like machine learning and reinforcement learning.   For example, a robotic arm in a car manufacturing plant is programmed to weld specific parts in a fixed sequence. It uses sensors for precision but does not learn or adapt its welding technique over time. This is an example of robotics, relying on traditional control systems without the learning aspect of Embodied AI. On the other hand, ATLAS from Boston Dynamics learns to walk, run, and perform tasks by interacting with its environment and improving its skills through experience. This demonstrates Embodied AI, as the robot's AI system adapts based on physical feedback. Robotics vs Embodied AI (Source: FANUC, Boston Dynamics) Future of Embodied AI The future of Embodied AI depends on advancement of exciting trends and technologies that will make robots smarter and more adaptable.

Data Requirements for Embodied AI The ability of Embodied AI to learn from and adapt to environments depends on the data on which it is trained. Therefore the data play an important role in building Embodied AI. Following are the data requirements for Embodied AI. Large-Scale, Diverse Datasets Embodied AI systems need a large amount of data about different environments and sources to learn effectively. This diversity helps the AI understand a wide range of real-world scenarios, from different lighting and weather conditions to various obstacles and environments. Real-Time Data Processing and Sensor Integration Embodied AI systems use sensors like cameras, LIDAR, and microphones to see, hear, and feel their surroundings. Processing this data quickly is crucial. Therefore the real-time data processing solution (e.g., GPUs, neuromorphic chips)  is required to allow the AI to make immediate decisions, such as avoiding obstacles or adjusting its actions as the environment changes. Data Labeling Data labeling is a process to give meaning to raw data (e.g., “this is a door,” “this is an obstacle”). It is used to guide supervised learning models to recognize patterns correctly. Poor labeling leads to errors, like a robot misidentifying a pet as trash. Data labeling is a tedious job, data labeling tools with AI assisted labeling is needed for such tasks. Quality Control High-quality data is key to reliable performance. Data quality control means checking that the information used for training is accurate and free from errors. This ensures that the AI learns correctly and can perform well in real-world situations. The success of embodied AI depends on  large and diverse datasets, the ability to process sensor data quickly, clear labeling to teach the model, and rigorous quality control to keep the data reliable.   How Encord Contributes to Building Embodied AI The Encord platform is uniquely suited to support embodied AI development by enabling efficient labeling and management of multimodal dataset that include audio, image, video, text, and document data.

DJI, a dominant force in the drone industry, has introduced cutting-edge models tailored for agriculture. The Mavic 3M, a multispectral imaging drone, enables farmers to monitor crop health accurately. This drone uses Real-Time Kinematics (RTK) technology for centimeter-level positioning. For large-scale operations, DJI Agras T50 and T40 drones offer robust crop spraying and spreading capabilities, allowing for efficient pesticide and fertilizer application. These drones integrate AI-powered route planning and RTK positioning to ensure precise operations and minimize environmental impact.  Beyond DJI, Parrot has developed drones with high-resolution imaging capabilities tailored for agricultural use. For example, the Parrot Bluegrass Fields provides in-depth crop analysis and covers up to 30 hectares with a 25-minute flight time.  AgEagle Aerial Systems, known for its eBee Ag unmanned aerial system (UAS), offers aerial mapping solutions to help farmers make data-driven decisions. Meanwhile, XAG, a rising competitor, specializes in autonomous agricultural drones. One example is the XAG P100, which integrates AI and RTK technology for precise spraying and seeding. Such companies are shaping the future of smart agriculture by combining automation, high-resolution imaging, and advanced navigation. Case Study from John Deer John Deere has been at the forefront of integrating autonomous technology into agriculture. In 2022, the company introduced its first autonomous tractor, which has since been used by farmers across the United States for soil preparation.  Building on this success, John Deere plans to launch a fully autonomous corn and soybean farming system by 2030. The system will address labor shortages and enhance productivity.  The company's latest Autonomy 2.0 system features 16 cameras providing a 360-degree view and operates at flight speeds up to 12 mph, a 40% increase over previous models. John Deere seeks to improve agriculture efficiency, safety, and sustainability by automating repetitive tasks. Autonomous Agriculture Beyond Traditional Drones Agricultural drones have transformed how we monitor crops and spray, but the next evolution lies in autonomous agriculture robotics. These systems go beyond aerial capabilities, incorporating ground-based robots that carry out tasks such as planting, weeding, and harvesting with unmatched precision.  The transition from drones to robotics represents a natural progression in precision agriculture. Drones are excellent for aerial data collection and spraying, but ground-based robots can manage more complex, labor-intensive tasks.  For example, robots with computer vision and AI can identify and remove weeds without damaging crops, reducing herbicide use by up to 90%. Robots like FarmWise’s Titan FT-35 use AI to distinguish crops from weeds and mechanically remove invasive plants. Laser-based systems, such as Carbon Robotics’ LaserWeeder, eliminate weeds accurately, saving farmers thousands in herbicide costs.  Additionally, Ground robots with multispectral cameras and sensors can monitor soil moisture, nutrient levels, and plant health in real time. Robots like Ecorobotix’s ARA analyze soil composition and apply fertilizers with variable-rate precision, ensuring optimal nutrient delivery. https://encord.com/blog/computer-vision-in-agriculture/ Data and Tooling Requirements for Building Agricultural Robots Developing agricultural robots requires a comprehensive approach to data and technology. The process begins with collecting high-quality, relevant data, which forms the foundation for training and refining the AI models that enable autonomous operation in agricultural fields. Data Collection Data collection is the most critical aspect of developing agricultural robots. The data must come from various sources to capture the complexity of agricultural environments. This includes real-time data from sensors embedded in robots or placed across fields to measure soil moisture, temperature, pH levels, and nutrient content.  Cameras and multispectral sensors capture detailed imagery of crops, allowing for analysis of plant health, growth stages, and pest presence. Historical data, including weather patterns, previous crop yields, and soil health data, adds layers of predictive capability to AI models. AI and ML Platforms The "brains" of agricultural robots consist of AI and ML algorithms, which require powerful software tools and platforms. These platforms help create and train intelligent models that enable robots to perceive, understand, and act in agricultural environments. Machine Learning and Computer Vision Frameworks ML platforms like TensorFlow and PyTorch train AI models that allow image recognition for weeding and disease detection. Additionally, specialized frameworks from NVIDIA for GPU acceleration enhance speed. OpenCV, an open-source CV library, offers a collection of algorithms for image processing, feature extraction, object detection, video analysis, and more. It is widely used in robotics and provides essential building blocks for vision-based agricultural robot applications. Robotics Middleware and Frameworks ROS (Robot Operating System) is a widely adopted open-source framework for robotics software development. It simplifies sensor integration, navigation, motion planning, and simulation. Key features include: Sensor integration and data abstraction: Provides a unified interface for accessing and processing sensor data. Navigation and localization: Offers pre-built algorithms, mapping tools, and localization techniques (e.g., SLAM) for autonomous robot navigation. Simulation Environments: ROS integrates seamlessly with simulation environments like Gazebo. It enables developers to test and validate robot software in a virtual world before deploying it to real hardware. Edge AI Platforms NVIDIA Jetson embedded computing platforms (e.g., Jetson AGX Orin, Jetson Xavier NX) are widely used in robotics to balance performance and energy efficiency. They provide potent GPUs and execute complex AI models directly on robots in real-time. Google Coral provides edge TPU (Tensor Processing Unit) accelerators that are specifically designed for efficient inference of TensorFlow Lite models. Coral platforms are cost-effective and energy-efficient. This makes them suitable for deploying lightweight AI models on robots operating in power-constrained environments. Hardware Considerations and Software Integration Requirements Selecting the appropriate hardware is equally important because the physical environment of a farm is harsh and unpredictable. Robots must be designed to withstand dust, water, extreme temperatures, and physical shocks.  This requires selecting durable materials for the robot's body, ensuring that sensors and cameras are both protected and functional. It is also important to choose batteries that provide long life and fast recharge capabilities. The software must also be robust and capable of managing diverse data inputs, processing them efficiently, and sending commands to the robotic systems. Additionally, the software should integrate seamlessly with existing farm management software, Internet-of-Things (IoT) devices, and other agricultural robots or drones for an effective farm management solution.  Challenges of Building Agricultural Robots Despite the advantages of deploying agricultural robots, several challenges stand in the way of their widespread adoption and effective operation. Environmental factors: Agricultural robots face challenges due to unpredictable environments, including rough terrain, mud, and severe weather, which can affect their sensors and mobility systems. Hyperspectral cameras and LiDAR often fail in fog or low-light conditions, reducing data accuracy. Regulatory constraints: Varied regulations across regions can limit operational areas and require certifications. Additionally, they impose data privacy and usage restrictions, complicating operations. High initial costs: Significant upfront costs are associated with research, engineering, and software development. High-performance components contribute to expensive robot systems. Collecting and labeling large datasets for AI training is resource-intensive. Data quality: Robots rely on high-quality data for disease detection and yield prediction tasks. However, bias in training data poses challenges, such as models trained on monoculture farms failing in diverse cropping systems. Additionally, annotating crop imagery for ML requires precise tagging of subtle features, which is time-intensive and error-prone. Maintenance: Regular maintenance is necessary in harsh agriculture, but it can be logistically challenging and costly, particularly in remote or expansive farming areas. How Encord Helps Build Agricultural Drones: Conquering Data Challenges With a Data-Centric Platform As we discussed, building efficient agricultural robots presents numerous challenges, mainly due to the inherent complexities of agricultural data. Agricultural sensor data is often noisy and imperfect due to environmental factors. Human annotation can introduce errors and inconsistencies, which can impact model accuracy.  These data quality challenges can greatly hinder developing and deploying effective agricultural drone and robot systems.

Google DeepMind’s latest work on Gemini 2.0 for robotics shows a remarkable shift in how large multimodal AI models are used to drive real-world automation. Instead of training robots in isolation for specific tasks, DeepMind introduced two specialized models: Gemini Robotics: a vision-language-action (VLA) model built on Gemini 2.0. It accepts  physical actions as a new output modality for directly controlling robots. Gemini Robotics-ER: a version of Gemini that incorporates embodied reasoning (ER) and spatial understanding. It allows roboticists to run their own programs along with Gemini’s spatial reasoning capabilities. This is monumental because Google demonstrates how you can take a multimodal artificial intelligence model, fine-tune it and apply it for robotics. Since it is multimodal, the robotic systems learn to generalize better rather than being proficient at a particular task without needing massive amounts of data to add a new ability. In this blog we will go through the key findings of the Gemini Robotics, the architecture, training pipeline and discuss the new capabilities it unlocks.  Why Traditional Robotics Struggle? Training robots has always been an expensive and complex task. Most of the robots are trained with supervised datasets, reinforcement learning or imitation learning, but each approach has significant limitations. Supervised learning: needs massive annotated datasets. This makes scaling difficult. Reinforcement learning (RL): It has only been proven effective in controlled environments. It still needs millions of trial and error interactions and still fails to generalize to the real-world applications. Imitation learning (IL): It is efficient but it needs large scale expert demonstrations. It can be difficult to find demonstrations for each and every scenario. These challenges lead to narrowly specialized models that work well in training environments but break down in real-world settings. A warehouse robot trained to move predefined objects might struggle if an unexpected item appears. A navigation system trained in simulated environments might fail in new locations with different lighting, obstacles, or floor textures.  Hence, the core issue of traditional robots is the lack of true generalization. However, DeepMind’s Gemini Robotics presents a solution to this problem by rethinking how robots are trained and how they interact with their environments.  What Makes Gemini Robotics Different? Gemini Robotics is a general-purpose model capable of solving dexterous tasks in different environments and supports different robot embodiments. It uses Gemini 2.0 as a foundation and extends the multimodal capabilities to not only understand tasks through vision and language but also to act autonomously in the physical world. The integration of physical actions as a new output modality, alongside vision and language processing, allow the model to control robots directly. It helps the robots to adapt and perform complex tasks with minimal human interventions. Source Architecture Overview Gemini Robotics is built around an advanced vision-language-action model (VLA), where vision and language inputs are integrated with robotic control outputs. The core idea behind this is to help the model to perceive its environment, understand natural language instructions and act in the real-world task by controlling the robot’s actions.  It is a transformer based architecture. The key components include: Vision Encoder: This module processes visual inputs from cameras or sensors, extracting spatial and object-related information. The encoder is capable of recognizing objects, detecting their positions, and understanding environmental contexts in dynamic settings. Language Encoder: The language model interprets natural language instructions. It converts user commands into an internal representation that can be translated into actions by the robot. The strength of Gemini Robotics lies in its ability to comprehend ambiguous language, contextual nuances, and even tasks with incomplete information. Action Decoder: The action decoder translates the multimodal understanding of the environment into actionable robotic movements. These include tasks like navigation, object manipulation, and interaction with external tools. Training Pipeline The training of these models is also unique as it combines multiple data sources and tasks to ensure that the model is good at generalizing across different settings.  Data Collection The training process begins with collecting a diverse range of data from robotic simulations and real-world environments. This data includes both visual data such as images, videos, depth maps, and sensor data, and linguistic data such as task descriptions, commands, and natural language instructions. To create a robust dataset, DeepMind uses a combination of both synthetic data from controlled environments and real-world data captured from real robots performing tasks. Pretraining The model is first pretrained on multimodal datasets, where it learns to associate vision and language patterns with tasks. This phase is designed to give the model an understanding of fundamental object recognition, navigation, and task execution in various contexts. Pretraining helps the model learn generalizable representations of tasks without having to start from scratch for each new environment. Fine-tuning on Robotic Tasks After pretraining, the model undergoes fine-tuning using real-world robotic data to improve its task-specific capabilities. Here, the model is exposed to a wide range of tasks from simple object manipulation to complex multi-step actions in dynamic environments. Fine-tuning is done using a combination of supervised learning for task labeling and reinforcement learning for optimizing robotic behaviors through trial and error. Reinforcement Learning for Real-World Adaptation A key component of the Gemini Robotics pipeline is the use of reinforcement learning (RL), especially in the fine-tuning stage. Through RL, the robot learns by performing actions and receiving feedback based on the success or failure of the task. This allows the model to improve over time and develop an efficient policy for action selection. RL also helps the robot generalize its learned actions to different real-world environments. Embodied Reasoning and Continuous Learning The model is also designed for embodied reasoning, which allows it to adjust its actions based on ongoing environmental feedback. This means that Gemini Robotics is not limited to a static training phase but is capable of learning from new experiences as it interacts with its environment. This continuous learning process is crucial for ensuring that the robot remains adaptable, capable of refining its understanding and improving its behavior after deployment. Gemini Robotics-ER Building on the capabilities of Gemini Robotics, this model introduces embodied reasoning (ER). What is Embodied Reasoning? Embodied reasoning refers to the ability of the model to understand and plan based on the physical space it occupies. Unlike traditional models that react to sensory input or follow pre-programmed actions, Gemini Robotics-ER has a built-in capability to understand spatial relationships and reason about movement.  Source This enables the robot to assess its environment more holistically, allowing for smarter decisions about how it should approach tasks like navigation, object manipulation, or avoidance of obstacles. For example, a robot with embodied reasoning wouldn’t just move toward an object based on visual recognition. Instead, it would take into account factors like: Spatial context: Is the object within reach, or is there an obstacle blocking the way? Task context: Does the object need to be lifted, moved to another location, or simply avoided? Environmental context: What other objects are nearby, and how do they affect the task at hand? Source Gemini 2.0’s Embodied Reasoning Capabilities The Gemini 2.0 model already provided embodied reasoning capabilities which are further improved in the Gemini Robotics-ER model. It needs no additional robot-specific data or training as well. Some of the capabilities include: Object Detection: It can perform open-world 2D object detection, and generate accurate bounding boxes for objects based on explicit and implicit queries. Pointing: The model can point to objects, object parts, and spatial concepts like where to grasp or place items based on natural language descriptions. Trajectory Prediction: Using its pointing capabilities, Gemini 2.0 predicts 2D motion trajectories grounded in physical observations, enabling the robot to plan movement. Grasp Prediction: Gemini Robotics-ER extends this by predicting top-down grasps for objects, enhancing interaction with the environment. Multi-View Correspondence: Gemini 2.0 processes stereo images to understand 3D scenes and predict 2D point correspondences across multiple views. Example of 2D trajectory prediction. Source How Gemini Robotics-ER Works? Gemini Robotics-ER incorporates several key innovations in its architecture to facilitate embodied reasoning. Spatial mapping and modeling This helps the robot to build and continuously update a 3D model of its surroundings. This spatial model allows the system to track both static and dynamic objects, as well as the robot's own position within the environment. Multimodal fusion It combines vision sensors, depth cameras, and possibly other sensors (e.g., LiDAR).  Spatial reasoning algorithms These algorithms help the model predict interactions with environmental elements. Gemini Robotics-ER’s task planner integrates spatial understanding, allowing it to plan actions based on real-world complexities. Unlike traditional models, which follow predefined actions, Gemini Robotics-ER can plan ahead for tasks like navigating crowded areas, manipulating objects, or managing task sequences (e.g., stacking objects). ERQA (Embodied Reasoning Quality Assurance) It is an open-source benchmark to evaluate embodied reasoning capabilities of multimodal models. In the fine-tuned Gemini models it acts as a feedback loop which evaluates the quality and accuracy of spatial reasoning, decision-making, and action execution in real-time. ERQA Question categories. Source The core of ERQA is its ability to evaluate whether the robot's actions are aligned with its planned sequence and expected outcomes based on the environment’s current state. In practice, ERQA ensures that the robot: Accurately interprets spatial relationships between objects and obstacles in its environment. Adapts to real-time changes in the environment, such as moving obstacles or shifts in spatial layout. Executes complex actions like object manipulation or navigation without violating physical constraints or failing to complete tasks. The system generates feedback signals that inform the model about the success or failure of its decisions. These signals are used for real-time correction, ensuring that errors in spatial understanding or action execution are swiftly addressed and corrected. Why Do These Models Matter for Robotics? One of the biggest breakthroughs in Gemini Robotics is its ability to unify perception, reasoning, and control into a single AI system. Instead of relying solely on robotic experience, Gemini leverages vast external knowledge from videos, images, and text, enabling robots to make more informed decisions. For example, if a household robot encounters a new appliance it has never seen before, a traditional model would likely fail unless it had been explicitly trained on that device. In contrast, Gemini can infer the appliance's function based on prior knowledge from images and instructional text it encountered during pretraining. This ability to extrapolate and reason about unseen scenarios is what makes multimodal AI so powerful for robotics. Through this approach, DeepMind is laying the foundation for more intelligent and adaptable humanoid robots capable of operating across a wide range of industries from warehouse automation to household assistance and beyond. Conclusion In short, Google introduces models and benchmarks and shows how robots can do more and adapt more to different situations. By being general, interactive, and dexterous, it can handle a variety of tasks, respond quickly to changes, and perform actions with precision, much like humans.  📘 Download our newest e-book, The rise of intelligent machines to learn more about implementing physical AI models.

Imagine a world where in the morning the sun rises over busy cities not just with human activity but also with the intelligent machines moving around. A world where your morning coffee is brewed by a robot that not only knows your exact taste preferences but also navigates a kitchen with human-like grace. In this world autonomous delivery drones or robots navigate the urban maze and deliver fresh groceries, essential medicines, and even lunch orders directly to your doorstep.

It is suggested that by 2035, there could be as many as 1.3 billion AI-powered robots operating across the globe. In manufacturing alone, the integration of Physical AI could unlock a multi trillion-dollar market, while advancements in healthcare and transportation promise to dramatically improve safety and efficiency. These statistics underline the enormous potential as well as requirement to harness Physical AI for practical, real-world applications. Jensen Huang speaking about humanoids during the 2025 CES event (Source) In this blog, we will deep dive into the world of Physical AI. We'll explore what it is, how it is different from other forms of AI like embodied AI. We will also discuss the data and hardware challenges that need to be overcome and discuss the importance of AI alignment in creating safe systems. We will also explore the role of Encord in Physical AI.  What is Physical AI? Physical AI refers to the integration of AI (exists in software form), with physical systems. Physical AI enables machines to interact with and adapt to the real world. It combines AI algorithms, such as machine learning, computer vision, and natural language processing, with robotics, sensors, and actuators to create systems that can perceive, reason, and act in physical environments. Block diagram of the Newton Physical AI foundation model (Source) Key Characteristics of Physical AI Following are the key characters of Physical AI. Embodiment: Physical AI systems are embodied in physical forms, such as robots, drones, or autonomous vehicles which allow it to interact directly with its surroundings. Perception: Physical AI systems make use of sensors (e.g., cameras, microphones, LiDAR) to gather data about their environment. Decision-Making: AI algorithms in Physical AI systems process sensor data to make decisions or predictions. Action: Actuators (e.g., motors, arms, wheels) enable these systems to perform physical tasks, such as moving, grasping, or manipulating objects. Adaptability: Physical AI systems can learn and adapt to new situations or environments over time. Components of Physical AI System Physical AI systems integrate hardware, software, and connectivity to enable intelligent interaction with the physical world. The following are the core components: Sensors Sensors allow Physical AI systems to see and feel  their environment. Sensors help it to collect real-time data enabling the system to understand and respond to external conditions. It can use one or more of the following sensors to understand its surroundings. Cameras: It is used for computer vision tasks. Cameras capture visual information and allow the system to recognize objects, track movements, and interpret visual cues. LiDAR/Radar: These sensors emit signals and measure their reflections to create detailed 3D maps of surroundings. These sensors are essential for navigation. Microphones: It helps capture audio data, enabling the system to process sounds for voice recognition. Inertial Measurement Units (IMUs): It comprises accelerometers and gyroscopes to track motion, orientation, and acceleration. It also helps in stabilizing the physical body of Physical AI  systems. Temperature, Pressure, or Proximity Sensors: These sensors monitor environmental factors such as heat, force, or distance to nearby objects and allow the Physical AI system to react appropriately to changes. Actuators Actuators are responsible for executing physical actions based on the decisions taken by the system in order to enable interaction with the environment. For example, if a robot sees an apple through a camera and receives instruction to pick it up through a microphone, it uses different motors in its arm to plan a path to pick it up. Following are some actuator devices: Motors: Drive components like wheels or robotic arms assists the movement and manipulation of objects. Servos: Provide precise control over angular or linear positions which are crucial for tasks requiring exact movements. Hydraulic/Pneumatic Systems: It uses fluid or air pressure to generate powerful movements and are used in heavy machines or robotic systems requiring significant force. Speakers: It converts electrical signals into sound to provide audio feedback or communicate with users. AI Processing Units The AI processing units handle the intensive computations required for processing sensor data and running AI algorithms to make real-time decisions. Some examples are following: Graphics Processing Units (GPUs): Specialized for parallel processing, GPUs accelerate tasks like image and signal processing which are essential for real-time AI applications. Tensor Processing Units (TPUs): Custom-developed by Google, TPUs are designed to efficiently handle machine learning workloads, particularly for neural network computations. Edge Computing Devices: These processors enable data processing at the source (i.e., on the device itself), reducing latency and reliance on cloud connectivity, which is vital for time-sensitive applications. NVIDIA Jetson Orin Nano Dk for Edge AI (Source) Mechanical Hardware It is the physical components that provide structure to Physical AI and facilitate movement. It provides the tangible interface between the AI system and its environment. The following are some of the examples: Chassis/Frames: It provides foundational structures to robots, drones, or vehicles and supports all other components of the system. Articulated Limbs: These are the robotic arms or legs that have multiple joints to allow movements and the ability to perform complex tasks. Grippers/Manipulators: These are the end-effectors designed to grasp, hold, or manipulate objects. It enables the system to interact physically with various items. MIRAI AI Enabled Robotic ARM from KUKA (Source) AI Software & Algorithms This is the brain of the Physical AI system. It processes the sensor data and helps in making decisions. The key software for Physical AI are as follows. Machine Learning Models: It is one of the most important parts of Physical AI as it helps the system to understand its environment. It enables systems to learn optimal actions through trial and error. Robot Operating System (ROS): ROS is the open-source robotics middleware. It is a framework that provides a collection of software libraries and tools to build robot applications and enables hardware abstraction and device control. Control Systems The control system translates the decision from AI Software and Algorithm into commands which are executed by actuators. Following are the important control systems: PID Controllers: PID controller uses proportional, Integral, and derivative calculations for the system outputs such that required for the motion control. Real-Time Operating Systems (RTOS): RTOS manages hardware resources and ensures real-time execution of tasks. This is very important in Physical AI systems which require precise timing. Can AI Have a Physical Form? When most people imagine AI, they think of it as some application, computer programs, or invisible systems like Netflix suggesting a show, Siri answering questions, or chatbots like ChatGPT answering queries. This kind of AI lives entirely in the digital world and works behind the scenes like a ghost that thinks and calculates but it can not move around us and touch and interact with the physical world. In this application, the ai is a software system, like a brain without a body. Physical AI flips this idea. Instead of being trapped in a computer's memory, the Physical AI  gets a body, for example, a robot, self-driving car, or smart machine. Imagine a robot that does not only figure out how to pick up a cup but actually reaches for it, grabs it, and hands it to you. Physical AI connects thinking (algorithms) to real-world action. To do this, it needs: Eyes and ears through sensors (cameras, microphones, radar) to see and hear. A brain which are the processors to understand what is happening. Arms and legs through motors, wheels, or grippers so that it can move and interact. SenseRobot: AI-Powered Smart Chess Coach and Companion (Source) Just take an example of a self-driving car, which does not only think about driving but uses cameras to spot stop signs, calculates when to brake, and actually physically presses the brake pedal. Similarly, a warehouse robot that may use AI to find a package, navigate around people, and lift it with mechanical arms. MARS rover uses AI to identify organic materials in the search for life on Mars (Source) Why does this matter? Because traditional AI is like a smart assistant on your phone, it can talk or answer queries, but it can not do anything physical. On the other hand, Physical AI can act. It can build things, clean your house, assist surgeons, or even explore Mars. By giving AI a body, we’re turning it from a tool that thinks into a partner that acts. This will change the way we live, work, and solve problems in the real world. So, we can say that a traditional AI is the brain that thinks, talks, and calculates. Whereas, Physical AI is the brain and the body that thinks, sees, moves, interacts and is possible indeed. Physical AI vs. Embodied AI Although Physical AI and Embodied AI seem similar at a glance. They are quite different. Let's understand the difference between the two. The Physical AI systems are integrated with physical hardware (sensors, actuators, robots etc.) to interact with the real world. The main focus in Physical AI  is to execute tasks in physical environments. It combines AI algorithms with mechanical systems and can perform operations such as movement, grasping, navigation. This type of AI relies on hardware (motors, cameras, wheels) to interact with surroundings. An example of Physical AI are self-driving cars that use AI to process sensor data (cameras, radar) and physically control steering, brake, or acceleration. Another example is warehouse robots like Amazon’s Sparrow that use AI to identify, grab, and sort packages.  Embodied AI systems on the other hand are designed to learn and reason through physical interaction with their environment. They focus on intelligence that comes from having a body. The emphasis in Embodied AI is on intelligence that comes from a body’s experiences similar to humans who learn by touching, moving, and interacting. The goal of Embodied AI is to learn skills (e.g., walking, grasping) through trial and error in the real world. Framework of Embodied Agent (Source) An example of Embodied AI is Atlas Robot from Boston Dynamics that learns to balance, jump, or navigate uneven terrain by adapting its body movements.   We can summarize the difference between the Physical AI is the AI with a body that acts to solve practical problems (e.g., factory automation) and Embodied AI is the AI that needs a body to learn to improve intelligence (e.g., teaching robots common sense through interaction). The Promise of Physical AI The promise of Physical AI lies in its ability to bring digital intelligence into the tangible physical world. Physical AI is revolutionizing the way machines work alongside humans and transform different industries. Following are key sectors where Physical AI is set to make a huge impact. Healthcare There are many applications of Physical AI in healthcare. For example, surgical robots use AI-guided systems to perform minimally invasive surgeries with precision. Wearable robots such as rehabilitation exoskeletons help patients regain mobility by adapting to their movements in real time. AI powered autonomous robots deliver supplies, sanitize rooms, or assist nurses with repetitive tasks. Exoskeleton control neural network (Source) Manufacturing In manufacturing, collaborative robots (Cobots) are the AI-powered arms that work alongside humans. Cobots learn to handle delicate tasks like assembling electronics or doing more complex tasks that require precision similar to human hands.  Techman AI Cobot (Source) Agriculture In agriculture, AI-driven machines plant, water, and harvest crops while analyzing soil health. Weeding robots use computer vision to identify and remove weeds without chemicals and autonomous tractors drive themselves, avoid obstacles using computer vision and other sensor data and perform various farm tasks, from mowing to spraying. These autonomous tractors use sensors, GPS, and artificial intelligence (AI) to operate without a human in the cab. Driverless tractors perform fully autonomous spraying tasks at a Texas vineyard (Source) Logistics & Retail In Logistics & Retail, Physical AI power robots that sort, pack, and deliver goods with speed and accuracy. These robots use real-time decision-making with adaptive learning to handle a variety of products. For example, Proteus robots sort, pack, and move goods autonomously. Other machines like drones or delivery robots (e.g., Starship) navigate  to deliver packages. Amazon Proteus Robot (Source) Construction Physical AI has an important role to play in transforming how humans do construction. AI-driven excavators, bulldozers, and cranes operate autonomously or semi-autonomously to perform tasks like digging, leveling, and material placement. Companies like Caterpillar and Komatsu are leveraging AI to create smarter heavy machinery. AI-powered robotic arms can perform repetitive tasks like bricklaying, welding, and concrete finishing with high precision. Komatsu Autonomous Haulage System (AHS) (Source) Physical AI is redefining industries by turning intelligent algorithms into real-world action. From hospitals to highways, its ability to act in the physical world will create robots and machines that are not just tools, but partners in solving humanity’s greatest challenges. Data and Hardware Challenges in Physical AI The data and hardware challenges in Physical AI revolve around deploying and executing AI models within hardware systems, such as industrial robots, smart devices, or autonomous machinery. This creates some unique challenges related to data and hardware as discussed below. Data Challenges Availability of High Quality Data As with the many other AI systems, this is also an issue with Physical AI. Physical AI systems often require large, precise datasets to train models for tasks like defect detection and path planning etc. These datasets must reflect the exact physical conditions (e.g., lighting, material properties) of the deployment environment. For example, a welding robot needs thousands of labeled images of welds of different metals under various factory conditions and images taken from different angles to train a vision system. Such data is often not available and collecting it manually is costly and time-consuming. Data Annotation and Labeling Complexity Physical AI systems require accurately annotated data on a variety of data samples for training which require domain expertise and manual labeling effort. Since the AI must act in real physical condition it must be trained on all possible types of conditions the system may face. For example, training a Physical AI system to detect weld imperfections requires engineers to annotate thousands of sensor readings or images in which labeling error by humans may be possible. Adapting to New Situations Physical AI systems are trained on fixed datasets that don’t evolve post-deployment. It may be possible that physical settings (such as change in the environment, place or equipment) in which Physical AI is deployed may change which makes it hard for pre-trained models to work. For example, a robotic arm trained to assemble a specific car model might struggle if the factory switches to a new design. In such cases the model becomes obsolete and requires retraining with fresh data. Hardware Challenges Computational Power and Energy Constraints Running AI models such as deep learning for computer vision on physical hardware requires significant computational resources. Such types of AI models often exceed the capabilities of embedded systems. Battery-powered devices (e.g., IoT sensors) or small robots may also face energy limits and industrial systems need robust cooling. For example, a FANUC welding robot may use a GPU to process sensor data, but integrating this into a compact, energy-efficient unit is costly and generates heat. This may result in hardware failure in a hot environment in the factory. Sensor Limitations and Reliability Physical AI depends on sensors (e.g., cameras, LIDAR, force sensors) to perceive the environment. Sometimes these sensors may not give precise reading or fail under harsh conditions (e.g., dust, vibration). Calibrating these sensors repeatedly can also degrade its performance. For example, a camera on a robotic arm may misjudge weld alignment in poor lighting or if dust obscures the lens which leads to defective outputs. Integration with Legacy Hardware Many physical systems such as factory robots or HVAC units need modern AI models running on outdated processors or proprietary interfaces. Deploying such AI models into these systems is technically challenging and expensive. For example, upgrading a 1990s-era manufacturing robot to use AI for defect detection may require replacing its control unit which may disrupt the production lines. Latency and Real-Time Processing Needs Physical tasks such as robotic welding or autonomous navigation require real-time decision making that must happen in precise milliseconds but AI inference on resource-constrained hardware introduces latency issues. If the AI model is migrated to the cloud, the delays may occur due to network issues. For example, a welding robot adjusting its path in the middle of the welding process might lag if its AI model runs on a slow CPU which results in uneven welds. AI Alignment Considerations The AI alignment problem refers to the challenge of ensuring that AI systems act in ways that are aligned with human values, goals, and ethical principles. This problem becomes especially critical as AI systems become more capable and autonomous. The misaligned AI could potentially cause harm, either unintentionally or due to conflict in objectives. In the context of Physical AI the alignment problem takes on additional layers of complexity as AI systems interact with the physical world. Following are the key alignment problems related to physical AI. Real-World Impact Physical AI systems have direct impact in the physical world. Misalignment in these systems can lead to physical harm, property damage, or environmental disruption. For example, a misaligned autonomous vehicle might prioritize efficiency over safety but it may sometimes lead to accidents. Therefore, ensuring that physical AI systems understand and respect human intentions in real-world environments is a significant challenge. Unpredictable Environments Physical AI operates in environments that are often unpredictable and complex. This makes it harder to train such AI models in all possible scenarios.

Did you know the global e-commerce market is expected to reach $55.6 trillion in 2027? Research from the Harvard Business Review shows that emotional factors drive 95% of purchasing decisions, highlighting the importance of understanding customer sentiment for businesses. Yet, decoding these emotions at scale remains a challenge. A single Amazon product launch can generate thousands of reviews in days. Twitter sees 500 million daily tweets, many about brands. The volume is massive, but the real challenge is language. Human emotions are complex, and machines struggle to interpret them. This is where AI sentiment analysis becomes crucial. Using text analysis and natural language processing (NLP), businesses can decode customer sentiment and make sense of unstructured feedback data. The global sentiment analysis market is estimated to reach $11.4 billion by 2030. Businesses can automate the analysis of customer emotions, opinions, and attitudes at scale using artificial intelligence and machine learning models. However, building an effective tool comes with challenges, from ensuring high-quality datasets to overcoming linguistic complexities like negative sentiment, neutral sentiments, and contextual understanding. In this post, we’ll guide you step-by-step through the process of building your own AI sentiment analysis tool. Along the way, we will look at how platforms like Encord can help develop an AI sentiment analysis model that delivers actionable insights and improves customer experience.  Sentiment Analysis What is Sentiment Analysis? Sentiment analysis is an AI-driven technique that decodes emotions, opinions, and attitudes from unstructured data—text, audio, or video—to classify them as positive, negative, or neutral. It helps answer the question: How do people feel about a topic, product, or brand? Traditional methods depend on manual efforts, such as reading customer reviews, listening to customer support calls, or analyzing social media posts. However, with 80% of business data being unstructured, manual analysis is not scalable. AI can automate this process scale. For example, it can help with: Text Analysis: Scraping tweets like “This app changed my life!” or “Worst update ever, delete this!” to gauge brand sentiment. Audio Analysis: Detecting frustration in a customer’s tone during customer interactions over the phone. Multimodal Analysis: Combining facial expressions from video reviews with spoken words to better understand customer emotions. However, advanced models can classify emotions beyond just the polarity of positive or negative. They can also recognize emotions such as joy, anger, sadness, and even sarcasm. For example, a review stating, "The product was okay, but the delivery was terrible," would require the model to recognize mixed sentiment, neutral for the product and negative for the delivery. Challenges in AI Sentiment Analysis While AI-powered sentiment analysis has great potential for businesses, building a tool for it is not without its challenges, such as understanding the nuances of human language and the technical requirements of training AI models. Below, we discuss the key challenges of developing a sentiment analysis tool. Data Quality Issues Poor-quality or noisy data, such as misspelled words, irrelevant symbols, or inconsistent labeling, can degrade performance. Ensuring clean, well-structured datasets is critical but time-consuming. Contextual Understanding Human language contains nuances such as sarcasm, irony, and idiomatic expressions. A sentence like “Oh great, another delayed flight!” may seem positive at first glance, but it may be sarcastic. We need to use advanced natural language processing (NLP) methods and diverse datasets to help AI algorithms understand the context that reflects real-world situations.  Multilingual Support Sentiment analysis tools must support multiple languages and dialects for global businesses. However, linguistic differences, cultural contexts, and varying sentiment expressions (e.g., politeness in Japanese vs. directness in English) add layers of complexity. Automatically identifying textual data and applying sentiment analysis is essential, but building multilingual models demands extensive resources and expertise. Model Interpretability Many AI models, particularly those based on deep learning, function as "black boxes," which makes it difficult to understand how they reach particular conclusions. This lack of transparency can hinder trust and adoption for businesses. Ensuring model interpretability can overcome these issues. However, implementing interpretability is challenging because sometimes it requires simplifying complex models, which can reduce their accuracy or performance. Annotation Complexity Training accurate sentiment analysis models requires labeled data, but annotating large amounts of text or audio is labor-intensive and prone to human error. Ambiguities in language further complicate the process because different annotators may interpret the same text differently. Integration with State-of-the-Art Models The advancement of AI models such as GPT-4o and Gemini Pro and audio-focused models like Whisper brings both opportunities and challenges. Although these models provide state-of-the-art functionalities, integrating them into current workflows requires technical expertise and considerable computational resources. Tackling these challenges is crucial for building reliable sentiment analysis tools. Next, we’ll outline a process to create your AI sentiment analysis tool, using Encord to address data quality and annotation issues. How to Build an AI Sentiment Analysis Tool Building an AI sentiment analysis tool is a multi-stage process that transforms raw, unstructured data into actionable insights. From defining clear objectives to deploying models in real-world applications, each step requires careful planning, tools, and iterative refinement.  Below is a detailed guide to building your own sentiment analysis tool. It integrates machine learning, natural language processing (NLP), and platforms like Encord to streamline the annotation process. Step 1: Define Your Objective The foundation of any successful AI project lies in clarity of purpose. Begin by outlining the scope of your sentiment analysis tool. Will it analyze text (e.g., social media posts, customer reviews), audio (e.g., customer support calls, podcasts), or both?  For instance, a media company might prioritize multimodal analysis, combining video comments (text), tone of voice (audio), and facial expressions (visual). In contrast, a logistics company might focus solely on text-based sentiment from delivery feedback emails. Next, identify specific use cases. Are you aiming to improve brand monitoring by tracking social media sentiment during a product launch? Or optimizing customer support by detecting frustration in call center recordings? For example, a fintech startup could prioritize analyzing app store reviews to identify recurring complaints about payment failures.  Clear objectives guide data collection, model selection, and performance metrics, ensuring the tool aligns with business goals. Step 2: Collect and Prepare Data High-quality training data is the lifeblood of any AI model. Start by gathering raw data from relevant sources.  For text, this could include scraping tweets via the Twitter/X API, extracting product reviews from Amazon, or compiling customer emails from internal databases. Audio data might involve recording customer support calls or sourcing podcast episodes. However, raw data is rarely clean. Text often contains typos, irrelevant symbols, or spam (e.g., bot-generated comments like “Great product! Visit my website”).  Audio files may have background noise, overlapping speakers, or low recording quality. Preprocessing is critical: Text Cleaning: Remove HTML tags, correct misspellings (e.g., “gr8” → “great”), and filter out non-relevant content. Audio Cleaning: Isolate speech from background sounds using noise reduction tools like Adobe Audition or open-source libraries like LibROSA. Specialized tools like Encord can simplify this phase with automated preprocessing pipelines. For example, Encord's duplicate detection tool identifies redundant social media posts, while noise profiling flags low-quality audio files for review. A healthcare provider used Encord to clean 10,000+ patient feedback entries, removing 1,200 spam entries and improving dataset quality by 35%. Step 3: Annotate Data Using Encord Annotation, labeling data with sentiment categories like positive, negative, or neutral, is the most labor-intensive yet important phase. Manual labeling is slow and error-prone, especially for ambiguous phrases like “This app is fire… literally, it crashed my phone!” AI-powered annotation tools like Encord can streamline this process while addressing linguistic and technical challenges. Text Annotation Encord’s linguistic annotation framework enables granular labeling: Named Entity Recognition (NER): Identify brands, products, or people mentioned in the text. For example, tagging “iPhone 15” in the review “The iPhone 15 overheats constantly” helps link sentiment to specific products. Part-of-Speech (POS) Tagging: Parse grammatical structure to infer intent. Distinguishing “run” as a verb (“The app runs smoothly”) versus a noun (“Go for a run”) improves context understanding. Emotion Granularity: Move beyond polarity (positive/negative) to label emotions like sarcasm, urgency, or disappointment. Large Language Models (LLMs) like GPT-4o and Gemini Pro 1.5 are integrated into Encord’s workflow to pre-annotate text. For instance, GPT-4o detects sarcasm in “Love waiting 3 weeks for delivery! 🙄” by analyzing the eye-roll emoji and exaggerated praise. Human annotators then validate these suggestions, reducing manual effort by 60%. Customize document and text annotation workflows with Encord Agents. Audio Annotation Audio sentiment analysis introduces unique complexities: overlapping speakers, tonal shifts, and ambient noise. Encord’s layered annotation framework addresses these by enabling: Speech-to-Text Transcription: Automatically convert audio to text using OpenAI’s Whisper, which supports 100+ languages and accents. Tone & Pitch Analysis: Use Google’s AudioLM to tag segments as “calm,” “frustrated,” or “enthusiastic.” Sound Event Detection: Label non-speech elements (e.g., “door slamming,” “background music”) that influence context. Human-in-the-Loop Quality Control. Human-in-the-Loop Quality Control Encord’s active learning workflows prioritize ambiguous or impactful samples for review,  enabling annotators to focus on labeling data that affect model performance the most. For example, if a tweet is labeled as negative by some annotators and neutral by others, it gets flagged for review. This ensures accurate labeling, reduces bias and improves consistency, which are key factors for better AI models. Step 4: Train Your Model Once you have labeled your data, select a machine-learning framework or pre-trained model. For text, BERT and RoBERTa excel at understanding context, making them ideal for detecting sarcasm or nuanced emotions. Audio models like Wav2Vec 2.0 analyze tone and pitch, while hybrid architectures (e.g., Whisper + LSTM) combine speech-to-text with sentiment analysis. Fine-tuning adapts these models to your dataset: Pre-Trained Models: Start with a model trained on general data (e.g., BERT-base). Domain Adaptation: Train on your labeled data to recognize domain-specific terms, such as “CRP levels” in medical feedback or “latency” in gaming reviews. Class Imbalance: Address skewed datasets (e.g., 90% positive reviews) using techniques like oversampling minority classes or synthetic data generation with GPT-4o. Step 5: Evaluate Performance Testing on unseen data validates model reliability. Key metrics include: Precision: Measures how many predicted positives are correct (e.g., avoiding false alarms). Recall: Tracks how many actual positives are identified (e.g., missing fewer negative reviews). F1-Score: Balances precision and recall, ideal for imbalanced datasets. AUC-ROC: Evaluates the model’s ability to distinguish between classes (e.g., positive vs. negative). Step 6: Deploy and Monitor Deployment integrates the model into business workflows: API Integration: Embed the model into CRM systems or chatbots for real-time analysis. For example, a travel agency might flag negative tweets about flight delays and auto-respond with rebooking options. Cloud Deployment: Use platforms like AWS SageMaker or Google Vertex AI for scalable processing. Post-deployment, continuous monitoring is essential: Model Drift: Detects performance decay as language evolves (e.g., new slang like “mid” replacing “average”). Retraining: Use MLOps pipelines to auto-retrain models with fresh data monthly.

In the previous section, we covered the core process of building the tool.  Here, we’ll discuss additional features and functionalities you can incorporate to make your sentiment analysis tool more powerful, versatile, and impactful. Enhanced Contextual Understanding Basic sentiment analysis can classify text as positive, negative, or neutral. However, adding enhanced contextual understanding helps interpret sarcasm, humor, and cultural nuances: Sarcasm Detection: Train the model to recognize sarcasm by analyzing tone, word choice, and context. For instance, a tweet like "Oh fantastic, another delayed flight!" should be flagged as negative sentiment despite using the positive word "fantastic." Idiomatic Expressions: Incorporate support for idioms and colloquial language that varies across regions and cultures. For instance, people use phrases like "It’s not my cup of tea" to convey specific meanings that others must understand correctly. Contextual Disambiguation: Teach the model to differentiate similar words based on context. For example, it could detect slang like "sick" and interpret its meaning as either illness (negative) or an impressive quality (positive sentiment), depending on the context.  Multilingual Support A sentiment analysis tool should handle multiple languages and dialects while considering cultural differences in sentiment expression, as it is essential for global businesses. Language Detection: Automatically detect the language of the input text and apply the appropriate sentiment analysis model. Cultural Differences: Train the model to recognize how sentiment is expressed differently across cultures.  Translation Integration: Use translation APIs (e.g., Google Translate or DeepL) to preprocess multilingual data before sentiment analysis, ensuring consistent results across languages. Manage, curate, and label multimodal AI data. Real-Time Analysis Businesses require real-time insights to quickly respond to customer feedback and trends. Adding real-time analysis enables your tool to: Monitor Social Media Feeds: Monitor references to your brand on platforms such as Twitter, Facebook, or Instagram in real time.
