ABSTRACT:
An industrial robot system for starting a robot moving to a predetermined location according to starting instructions is equipped with detecting devices operating when the location reached by the robot once started is within a predetermined range from the predetermined location. Accordingly, the system is capable of preventing accidents caused by the operation when the work origin has drifted due to an abnormality in the robot. Because the robot is only allowed to do its work after an output is given by the detecting devices operating only when the robot thus started is within the predetermined range from the predetermined location, the robot system is capable of not only preventing accidents caused by the presence of abnormalities, but also controlling the operation of the robot with little chance of trouble.
