Abstract
A robot, such an industrial robot, has an arm. The arm has a plurality of rotation members, a plurality of joints each rotatably and mutually connecting adjacent two rotation members, and a plurality of electric servo motors respectively driving the joints. In this robot, every operation cycle, an angular speed is calculated at which to drive each servo motor, and a speed of a monitoring portion set in each rotation member is calculated. It is then determined whether or not the speed at the monitoring portion is equal to or lower than a reference speed. When it is determined that the speed at the monitoring portion is over the reference speed, the angular speed of each servo motor is instructed to reduce such that the speed at each monitoring portion becomes the reference speed or lower. The servo motors are driven at the angular speed that has been reduced.
