Title:
FAILURE DIAGNOSTIC DEVICE OF ROBOT
Document Type and Number:
Japanese Patent JP2021045820
Kind Code:
A
Abstract:
To accurately detect a failure of a light emitting section indicating the state of a robot.SOLUTION: A failure diagnostic device 20 diagnoses a failure of a light emitting section 14 for emitting light of a color according to the state of a robot 2 when a plurality of kinds of LEDs 15 to 17 having different light emitting colors are individually energized and turned on. The failure diagnostic device 20 includes: an energization control section 23 which controls energization to the LEDs 15 to 17; a voltage detection section 24 which detects diagnosis voltage Vd changing according to terminal voltage of the LEDs 15 to 17; and a failure detection section 25 which detects a failure of the light emitting section 14 on the basis of a control status of energization by the energization control section 23 and a detection value of the diagnosis voltage Vd by the voltage detection section 24.SELECTED DRAWING: Figure 2
