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.
Note：The product must be equipped with a 3D printed skeleton to use, but the product does not contain a 3D printed skeleton and needs to be purchased separately.
