A 6-DOF follower arm on DAMIAO quasi-direct-drive motors with a rack-and-pinion gripper and wrist camera, teleoperated by a passive Dynamixel leader arm and LeRobot-native.

In leader-follower teleoperation a person moves one arm, the leader, and a second arm, the follower, copies the motion. This article goes through how that setup works from nuclear hot cells to low-cost GELLO rigs, and walks through building and checking one in a FloMotion scene.

Motors turn in angles, while tasks are stated as positions and orientations in space. Kinematics is the geometry that links the two. This article goes through forward kinematics, the three families of inverse kinematics, and where each one appears in FloMotion.

A walking policy trained in simulation usually runs on a computer next to the robot. A small one fits on the microcontroller that drives the servos. This article follows such a policy onto an ESP32: the Arduino sketch, the FloMotion inference library, the model file in flash, and the same firmware running as the robot's controller in a FloMotion scene before any board is flashed.
