<p>A wrist mechanism for an industrial robot having a robot casing (18) robot arms (20, 20') capable of extending from and contracting to the robot casing, a robot hand (24) for gripping a workpiece, and a wrist (22) 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 (26,26') 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.</p> |
