A fault diagnosis device is configured to diagnose a fault in a light emitting unit that emits light of a color according to an operating state of a robot by individually energizing and lighting a plurality of types of LEDs of different emission colors. The fault diagnosis device includes an energization control unit that controls energization of the LEDs, a voltage detection unit that detects a diagnostic voltage that varies depending on a terminal voltage of the LEDs, and a fault detection unit that detects a fault in the light emitting unit based on a control state of energization by the energization control unit and a detected value of the diagnostic voltage by the voltage detection unit.
A fault diagnosis device for a robot, which is a device for diagnosing a fault in a light emitting unit that emits light of a color according to an operating state of the robot by individually energizing and lighting a plurality of types of light emitting diodes of different emission colors, the fault diagnosis device being installed in the robot, the fault diagnosis device comprising:
A robot system, comprising:
