Abstract

A robot, particularly an industrial robot for performing predetermined tasks in accordance with given programs. When an operating portion of the robot encounters an unexpected obstacle, the robot must immediately stop the motion of the operating portion to prevent the collision with obstacle. For this purpose, the robot is provided with subcontrol units for individually controlling each operating portion of the robot as well as a main control unit for performing overall control of the robot. The subcontrol units serve to control such extra operations other than the inherent operations to carry out the prescribed tasks. Each operating portion is equipped with various detecting devices for sensing obstacles. The subcontrol units are made operative in accordance with outputs from the corresponding detecting devices. As obstacles, there are included humans, gases, radiation, etc. in addition to various objects. This invention can be applied to a robot having a learning function.
