SO-ARM101 Low-Cost AI Arm 3D Printed Skeleton

SO-ARM101 Robotic Arm 3D-Printed Parts Kit – Made for LeRobot Framework

Meet the SO-ARM101: a 3D-printed robotic arm that doesn’t ask for much—just your undivided attention, some servos, and a taste for tinkering. Designed to integrate seamlessly with the LeRobot framework, this open-source-friendly kit is your ticket to hands-on robotics without mortgaging your GPU farm.

Ideal for students, hobbyists, and developers who prefer plastic that moves with purpose, the SO-ARM101 parts set makes it easy to explore inverse kinematics, pick-and-place routines, and “accidentally” drop objects across the room in the name of science.
