Abstract: 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.

Abstract: There is provided a robot system including robots installed on a floor surface and configured to execute a plurality of tasks. The robot system further includes an irradiating unit capable of irradiating visible light onto the floor surface. The irradiating unit is controlled so as to irradiate the visible light onto a motion area on the floor surface. The motion area is an area occupied on the surface of the floor by a space within which the robot is allowed to move during execution of the tasks.

Abstract: An industrial robot system is provided with a robot installed on a floor. In this robot system, a motion area is displayed visibly on the floor surface. The motion area is an area occupied on the floor surface by the robot when the robot executes a predetermined task.

Abstract: A robot system includes a robot installed on a floor surface, an irradiating unit irradiating visible light onto the floor surface, and a forcible stopping unit forcibly stopping the robot from moving when there occurs an abnormality. The radiating unit is controlled by a control unit such that visible light is radiated onto motion and latent areas on the floor surface. The motion area is an area occupied on the floor surface by a space within which the robot is allowed to move during execution of a task. The latent area is an area occupied on the floor surface by a space within which the robot is likely to move until the robot is forcibly stopped from moving by the forcible stopping unit. The control unit sets the latent area depending on whether or not an execution acceleration of the robot is higher than or equal to a predetermined acceleration.
