Seeed Studio SO-ARM101 Low-Cost AI Arm Servo Motor Kit Pro for LeRobot
The Seeed Studio SO-ARM101 represents the next generation of cost-effective, open-source AI robotic arms, building upon the foundational SO-ARM100 with significant enhancements. This version features optimized wiring to eliminate previous disconnection issues at Joint 3 and ensure unrestricted range of motion. A key upgrade includes different gear ratios for the leader arm's motors, boosting performance and removing the need for external gearboxes.
Crucially, the SO-ARM101 supports real-time leader-follower arm functionality, a vital feature for upcoming reinforcement learning (RL) applications where human intervention can correct robot actions. This robotic arm is designed for makers, educators, and AI enthusiasts seeking an affordable, yet powerful, platform for robotics and AI research.
Note: The SO-ARM101 requires a 3D printed skeleton for assembly, which is sold separately.

Applications & LeRobot Integration
Imitation Learning and Reinforcement Learning
The LeRobot framework offers seamless compatibility with the SO-ARM10x robotic arm, providing a complete toolkit for intelligent control and training. It facilitates:
- Data collection, model training, and deployment for adaptive learning.
- A powerful simulation platform for testing grasp and placement behaviors.
- Seamless integration with NVIDIA Jetson devices for accelerated on-edge performance.
Leveraging LeRobot on Jetson, training a custom robotic arm for complex tasks like grasping and object placement becomes efficient, fast, and ready for hardware deployment.
