LeRobot SO-101 - 6 Axis Robotic Arm

The SO-ARM101 is an open-source, 3D-printed robotic arm designed for embodied intelligence research. Hardware optimizations address issues like servo power and structural jams, enabling a focus on AI algorithm development. Unlike standard robotic arms, the SO-ARM101 is designed with learning at its core. It can be trained using techniques like imitation learning and reinforcement learning to perform tasks such as object manipulation and motion replication. The entire system—from hardware to software and algorithms—is fully open-source.

Unassembled DIY Robotics Kit

 

Simultaneously Updated With The Official Hugging Face project

The SO-ARM100 / 101 robotic arm is an official open-source project by Hugging Face. And this kit stay fully synchronized with the project, allowing users to follow the official tutorials and examples directly and experience new features as soon as the project is updated.

Community Inspiration

Walk through the whole dev journey with Nikodem Bartnik, using SO-ARM101 to showcase: from hardware assembly and servo control, to training a custom policy and achieving real-time block-picking inference. Follow his hands-on experience to understand every step, troubleshoot potential issues, and explore what’s possible with this open-source robotic arm.

 

Step-by-Step Assembly Instructions

The follower arm uses 6x STS3215 motors with 1/345 gearing. The leader, however, uses three differently geared motors to make sure it can both sustain its own weight and it can be moved without requiring much force. Which motor is needed for which joint is shown in the table below.

Leader-Arm Axis Motor Gear Ratio
Base / Shoulder Pan 1 1 / 191
Shoulder Lift 2 1 / 345
Elbow Flex 3 1 / 191
Wrist Flex 4 1 / 147
Wrist Roll 5 1 / 147
Gripper 6 1 / 147
