Seeed Studio Robot SO-ARM101 AI Arm Kits

Seeed Studio Robot SO-ARM101 AI Arm Kits are designed for LeRobot and Hugging Face projects, making them ideal for robotics developers. The SO-ARM101 kit from Seeed Studio includes servo motors, an adapter board, and cables, while the AI Arm printed skeleton kit includes the 3D-printed parts. Compared with the previous model, the SO-ARM101 features improved wiring that prevents the disconnection issues common at joint 3, and the enhanced wiring design does not limit the range of motion of the joints.
