AI summary

A robot automation system facilitates automated robotic manufacturing processes by employing a teaching subsystem including a tracking assembly that tracks movement of the mapping tool in a teaching workspace. A computing device in communication with the tracking assembly and the mapping tool receives tracking data from the tracking assembly and the mapping tool indicating movement of the mapping tool along a working path. Based on the tracking data, the computing device automatically generates robot instructions. A robot controller receives the robot instructions from the computing device and executes the robot instructions whereby the robot controller controls a robot and an end effector to conduct the automated robotic manufacturing process.
