Power and control for a seven-joint robot arm.

7DOF

Tether is a 7-DOF robotic arm built at Terra Labs USC. I work on its power and control.

An ESP32 master/slave setup drives the arm's 3 motor groups, with ROS2 on top.

The arm in the demo is a stand-in, not the real model.

Highlights

  • 7-DOF
  • ESP32 master/slave
  • 3 motor groups
  • ROS2
