In an industrial robot system, the robot is first moved to a starting position, and, when the temperature of the robot exceeds a predetermined value, a position checking operation is effected to move the robot towards the starting position so that, according to the difference between the starting position and the position where the robot has been stopped by the position checking operation, a compensation value is provided for temperature compensation of the robot, whereby, even when the working arms of the robot are extended or contracted by temperature variations, the robot can perform its working operation correctly.
