ABSTRACT:
It is constructed so as to detect a joint movement position of a robot arm by a position detector and a joint movement speed is calculated from change amounts of the joint movement position and elapsed time and is compared with an allowable movement speed and unlocking and locking of a brake are controlled so that the joint movement speed of an arm at the time of brake unlocking becomes within a constant value even when a shape, an attitude and a load condition of the robot arm vary. Therefore, movement work of the arm by the brake unlocking can be performed alone and a robot with high safety can be obtained.
