Power and control your SO-101 follower arm with this specialized electronics package based on the LeRobot SO-ARM100 specifications. This kit includes everything needed to operate the follower arm (the arm with the gripper that does the work): 6 high-torque 12V serial bus servos, a 12V power supply, a Seial Bus Servo Adapter, and all necessary wiring harnesses and connectors. **Important:** Leader and follower arms require different electronics due to voltage differences. This kit is specifically for the FOLLOWER arm (with gripper). For the leader arm (no gripper), you need the Leader Arm Electronics Kit which uses 7.4V servos. The 12V servos provide higher torque for gripper operation and task execution. Perfect for: - Completing your Follower Arm Frame Kit - Building teleoperation systems (pair with leader electronics) - Dual-follower AI setups (buy 2 kits for both followers) - Replacement or upgrade for existing follower arm **Note:** This is specifically for the FOLLOWER arm. For complete teleoperation, you also need the Leader Arm Electronics Kit.
This kit is based on SO-ARM100 (LeRobot Project) by Hugging Face and LeRobot Community.
