Abstract
A wrist mechanism for an industrial robot having a robot casing, robot arms capable of extending from and contracting to the robot casing, a robot hand for gripping a workpiece, and a wrist arranged between the robot arms and the robot hand, comprises: two reduction gears with a high reduction ratio connected respectively to each of two high speed rotational driving motors, the two reduction gears cooperating with one another for generating two individual reduced rotational outputs, and; two transmitting mechanisms, connectable to the hand, for transmitting respectively the two reduced rotational outputs to the hand, thereby causing respectively rotational motion and swinging motion of the hand.
