LeRobot SO-ARM101 Open-Source 6-Axis Robotic Arm Kit
LeRobot SO-ARM101 Open-Source 6-Axis Robotic Arm Kit
🤖 The most accessible entry into physical AI - collect data, train policies, watch your robot learn.
🔍 Product Overview
The SO-ARM101 is the hardware half of a complete end-to-end AI-robotics workflow built on the Hugging Face LeRobot project. Using a leader-follower pair, you teleoperate the arm to collect demonstration data, then train imitation-learning models (ACT, diffusion policies) that run on the arm itself. Six high-torque STS3215 bus servos with magnetic encoders give the positional accuracy imitation learning needs, and the fully open-source design integrates natively with the LeRobot Python library.
