Hiwonder NexArm Open-Source Embodied AI Robotic Arm with ESP32 & AT32 Dual-Chip Design, AI Vision, Large AI Model, and K230 Vision Module

Product Description Hiwonder NexArm is a high-performance open-source robotic arm built on the Hugging Face LeRobot project for end-to-end algorithm research and embodied AI learning. Featuring an ESP32 + AT32 dual-chip architecture, it combines high-precision magnetic encoder servos with an industrial-grade rail gripper for precise control and stable operation. A K230 vision module delivers 6 TOPS of equivalent compute, supporting AI vision tasks such as color recognition, object tracking, and intelligent sorting. Built-in multimodal large AI models enable NexArm to comprehend natural language and complex instructions, facilitating intelligent human-machine interaction. Advanced inverse kinematics and trajectory planning support dynamic precision control and coordinated leader-follower teleoperation. With data collection and imitation learning capabilities, NexArm adapts quickly to complex tasks and forms a closed-loop workflow from perception to execution. Hiwonder NexArm provides full-stack support from low-level hardware to end-to-end large AI model validation, while supporting expansion through HTTP APIs and serial communication for flexible integration and control. With strong deployment adaptability, NexArm integrates seamlessly with wheeled chassis, linear rails, conveyors, and other external equipment, enabling rapid setup of complex workflows. High-Precision Magnetic Encoder Bus Servo Built around a dual-output-shaft magnetic encoder servo system with all-metal gears. A powerful magnetic motor and real-time feedback from multiple algorithms ensure precise and stable joint movement. Advanced Inverse Kinematics Algorithms NexArm can detect target objects within the recognition area, calculate their position coordinates and placement angle, and adaptively adjust each joint through inverse kinematics to enable flexible grasping. Built for Imitation Learning Supports a leader-follower teleoperation system composed of a leader arm and a follower arm, with deep compatibility at the underlying level with the latest Hugging Face LeRobot framework. K230-Powered Hand-Eye Coordination Powered by the K230 module with 6 TOPS of computing power, NexArm supports 30+ AI vision functions including YOLO, as well as multimodal large-model deployment for advanced AI applications in complex scenarios. Color Recognition NexArm can accurately identify objects of different colors within its field of view, with different preset actions triggered through programming. Face Recognition Backed by the K230 chip's 6 TOPS of equivalent compute, NexArm can recognize and remember different faces, then trigger different programmed responses. Gesture Recognition Using the K230 vision module's YOLO algorithm, NexArm can accurately recognize different hand gestures and respond with different actions. AI Waste Sorting Powered by deep learning on the K230 vision module, NexArm can recognize different waste cards and sort them to designated locations based on instructions. Visual Object Tracking With large vision model analysis, NexArm can track and lock onto any object within its field of view. Complex Task Management NexArm can break down complex voice commands on its own and place items in the corresponding areas to complete complex handling tasks. Smart Home Assistant NexArm can send the live scene in view to a large vision model and combine it with instructions to generate matching language responses and actions. Intelligent Sorting With support from a large vision model, NexArm can identify target objects in view, adjust its posture in real time based on instructions, and pick and sort them into designated locations. Cross-Platform Control and Connectivity App Control Through the app, each NexArm joint can be controlled independently. Designated objects can also be grasped and sorted with flexible control, while preset action groups can be called up quickly. Offline Drag Teaching The leader arm can be dragged offline for intuitive demonstration. Combined with advanced imitation learning algorithms, the follower arm can accurately reproduce motion and grasping trajectories. Wireless Multi-Device Control Supports multilingual remote collaboration across multiple devices, with unicast, multicast, and broadcast modes. Automated scenarios can be deployed with ease, helping build a highly responsive AIoT collaborative ecosystem. Wireless Controller Control Equipped with a PS3 wireless controller and low-latency one-to-one pairing, allowing multiple devices to run side by side without interference. Programming support also enables different feedback actions on NexArm.
