Product Overview

SO-ARM101 is an open-source robotic arm deeply optimized from the SO-ARM100. Its upgraded wiring layout and motor-gear configuration fully eliminate joint wire breakage, with enhanced performance supporting real-time master-slave robotic arm synchronous follow-up. Seamlessly compatible with the Hugging Face LeRobot toolkit, it connects directly to PyTorch models and shared datasets, making imitation and reinforcement learning effortless to deploy. Complete with a full assembly tutorial and all-in-one DIY kit, it’s ideal for students, researchers, and makers to explore intelligent robotics innovation.

 

Key Advantages

  • Fully Open-Source & Customizable Design

    Compared to SO-ARMi00, SO-ARM101 features improved wiring thatprevents disconnection issues previously seen at joint 3. The new wiring design also no longerlimits the range of motion of the joints.

  • Integration with LeRobot

    Designed for integration with LeRobot platform which offersPyTorch models, datasets and tools for reinforcement learning and imitation learning for real-world robotics applications (including data collection, simulation, training and deployment).

  • Abundant learning resources

    Provides comprehensive open-source learning resources likeassembly and calibration guides, and tutorials for testing, data collection, training anddeployment to assist users in quickly getting started and developing robotic applications.
