SO-ARM101 Black Robotic Arm Kit
The SO-ARM101 Black Robotic Arm Kit is a compact dual-arm robotics platform designed for AI manipulation research, teleoperation, imitation learning, and hands-on robotics development.
The system includes two coordinated robotic arms:
Leader Arm — manually operated by the user to generate motion commands and collect demonstrations.
Follower Arm — mirrors the leader arm movement and can be used for teleoperation, dataset collection, and policy execution.
SO-ARM101 is part of the open-source SO-100 / SO-101 robotic arm ecosystem. The SO-101 design is described as the next-generation version of SO-100, with improved wiring, easier assembly, and updated motors for the leader arm.
The kit is intended for developers, researchers, educators, and robotics teams working with low-cost manipulation systems and AI-based robot learning.
