Hiwonder NexArm Open-Source VLA Embodied AI Robotic Arm with ESP32 & AT32 Dual-Chip Design, AI Vision, Large AI Model, and K230 Vision Module
-
【Next-Gen Embodied AI Robotic Arm】Built on an ESP32 + AT32 dual-chip architecture, with an industrial-grade all-metal body and advanced inverse kinematics algorithms, NexArm delivers a full-stack solution from low-level hardware to end-to-end large-model validation.
-
【Compatibility with LeRobot Ecosystem & End-to-End VLA Models】NexArm robotic arm is fully integrated with the LeRobot framework to access community models, datasets, and simulations. Developers can easily train and deploy end-to-end imitation learning algorithms and multimodal models like ACT & VLA.
-
【65 kg·cm High-Torque Magnetic Encoder Bus Servos】Industrial-grade high-precision magnetic encoder bus servos, combined with trapezoidal acceleration/deceleration and curve-smoothing algorithms, reduce start-stop jitter, enable smooth motion, and deliver ±2 mm repeatability.
-
【6 TOPS K230 Vision Module & Al Voice Interaction】NexArm robot arm equipped with the K230 Al vision module, with 30+built-in Al vision features including color/objects/gesture recognition and sorting, personalized face recognition, and more. Supports voice control, Al vision & voice interaction, and hand-eye coordinated grasping.
-
【Open-Source and Multi-Mode Control】Open-source code and schematics, plus PC software, app control, secondary development examples, and structured tutorials, significantly lower the barrier to embodied AI development.
Featuring a K230 AI vision module, NexArm handles voice interaction, visual perception, and hand-eye coordination. It also seamlessly integrates with mobile chassis, sliding rails, and conveyor belts to build full-scenario embodied AI systems.
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.
