Product Description NexArm is an open-source AI robotic arm platform built for embodied AI and VLA (Vision-Language-Action) learning. Featuring an industrial-grade, all-metal housing, high-precision magnetic encoder serial bus servos, dual-output shaft power joints, and in-house motion control algorithms, it delivers a stable, reliable hardware foundation for robot learning. NexArm covers the complete development pipeline, from teleoperation teaching and data collection to imitation learning and edge deployment. Fully compatible with the LeRobot ecosystem, it enables rapid deployment of cutting-edge robot policies like ACT, Diffusion Policy, and Pi0. 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. Seamless Hugging Face Ecosystem Integration The leader arm uses a 1:147 gear ratio for high-frequency demonstration capture, while the follower arm uses a 1:345 reduction ratio for superior positioning stability. This enables smooth access to Hugging Face community models for end-to-end imitation learning. 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. Parallel-Rail Gripper Silicone gripper pads and stainless-steel transmission components ensure asecure grip and improved durability. 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 a
