Key Advantages

  • Fully Open-Source & Customizable Design

    Compared to the SO-ARM100, the SO-ARM101 features improved wiring that eliminates the wire breakage issue previously occurring at Joint 3. The new wiring design also no longer restricts the joint's range of motion.

  • LeRobot Integration

    Purpose-built for integration with the LeRobot platform, which provides PyTorch models, datasets, and tools for real-world robotics applications — including data collection, simulation, training, and deployment — for reinforcement learning and imitation learning.

  • Rich Learning Resources

    Comprehensive open-source learning resources are provided, including assembly and calibration guides, as well as tutorials for testing, data collection, training, and deployment, helping users get started quickly and develop robotics applications.
