Robotics Electrical Service & Troubleshooting

SKET 164

Course Description

Prerequisites: Prerequisites: SKET 107 and SKMT 101.

Identifies the electrical component of robots, theory of operation. Introduces proper troubleshooting procedures for the robot controller and manipulator. Approximately 50 percent of the course will be hands-on troubleshooting of actual robot system and controller. Credit may be earned in SKET 164 or ET 164 but not both. (15-30)

Outcomes and Objectives

Operate Robot using basic procedures.

Objectives:

  • Follow safety guidelines and demonstrate use of emergency-stops and servo lockouts.
  • Properly power up robot controller and demonstrate fault recovery procedures.
  • Place robot in the following operating modes: automatic, low speed, and 100 percent manual modes.

Identify system components.

Objectives:

  • Identify manipulator motors, resolvers, calibration marks, counterbalance devices, hard stops, brake release buttons, and end-of-arm tooling.
  • Use robot controller computer and I/O modules, servo amps, motor relays, power supply.
  • Use teach pendant enabling device, motion device, e-stop and teach pendant buttons.
  • Identify control panel emergency stop button, motors on/off indicators, key switch, fault reset button, and floppy drive.
  • Verify robot synchronization using the calibration program.

Understand robotics circuits diagrams.

Objectives:

  • Understand theory of operation of the robot controller.
  • Describe components in the robot controller.
  • Explain principles of logical troubleshooting from power up through emergency stop loop and servo system.
  • Describe input/output interfacing between the S4C+ robot controller and peripheral equipment.
  • Operate the controller control panel and programming unit.
  • Read and interpret robot circuit diagrams on the robot controller.

Perforn troubleshooting techniques successfully.

Objectives:

  • Use safety precautions while troubleshooting the robot controller electrical system.
  • Set up commutation, resolver, counters, limit and sync switches.
  • Analyze and interpret system fault codes.
  • Diagnose and repair basic electrical faults.
  • Analyze servo-system data and make basic adjustments.
  • Diagnose and rectify emergency stop conditions.
  • Make I/O connections to peripheral equipment and safety devices.
  • Repair and replace systems components.
  • Review "Cold-Boot" procedure.
