Feature

What's news:

🌱Wiring optimization: Compared to SO-ARM100, SO-ARM101 features improved wiring that prevents disconnection issues previously seen at joint 3. The new wiring design also no longer limits the range of motion of the joints.

🌱Different gear ratios for the leader arm: The leader arm now uses motors with optimized gear ratios, improving performance and eliminating the need for external gearboxes.

🌱New functionality support: The leader arm can now follow the follower arm in real-time, which is crucial for the upcoming reinforcement learning (RL) policy, where a human can intervene and correct the robot’s actions.


Features of SO-ARM 10x Sereies:

🌱Open-source and low-cost: It is an open-source, low-cost robotic arm solution from TheRobotStudio.

🌱Integration with LeRobot: Designed for integration with LeRobot platform which offers PyTorch 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 like assembly and calibration guides, and tutorials for testing, data collection, training and deployment to assist users in quickly getting started and developing robotic applications.

🌱Compatible with Nvidia: Deploy this arm kit with reComputer Mini J4012 Orin NX 16 GB.

Application
Imitation learning and Reinforcement learning
The LeRobot framework is compatible with the SO-ARM10x robotic arm. It provides complete data collection, training, and deployment for teaching the robotic arm, and also has a comprehensive simulation platform. On the Nvidia Jetson edge device, it's easy and quick to train a customized robotic arm to complete grasping and placing tasks.
