ET 164 - Robotics Electrical Service & Troubleshooting

Credits: 3
Identifies the electrical components of robots, theory of operation. Introduces proper troubleshooting procedures for the robot controller and manipulator. Approximately 50 percent of the course is hands-on troubleshooting of actual robot system and controller. Credit may be earned in ET 164 or SKET 164  but not both.

Prerequisite(s): ET 120  and MT 220
