System and method for monitoring entry of object into surrounding area of robot

Abstract

A monitoring system monitors entry of an object into a surrounding area of a robot. The monitoring system includes visible light irradiation section, a sensor section and a monitoring control unit. The visible light irradiation section irradiates visible light from a level higher than that of the robot toward at least an outer edge portion of at least one of an operating area, which is set up to enclose a movable range of the robot, and a predetermined area which is set up around the operating area. The sensor section monitors entry of a new object, which is not registered in advance, into the operating area. The monitoring control unit issues a request for stopping the robot to a robot control unit that controls the robot, when entry of a new object into the operating area is detected by the sensor section.
