  • Underactuated mechanical finger capable of linear motion with compensatory displacement, mechanical gripper and robot containing the same
    Patent number: 10618182
    Abstract: The proximal phalanx of an underactuated mechanical finger includes a cam fixed on a linkage. Upon actuation, the linkage rotates the cam, which then drives a cam follower, which then drives an extensible part in the distal phalanx to extend the length of the finger, and therefore compensate the finger's height loss that would otherwise occur in the absence of the extensible part.

  • UNDERACTUATED MECHANICAL FINGER CAPABLE OF LINEAR MOTION WITH COMPENSATORY DISPLACEMENT, MECHANICAL GRIPPER AND ROBOT CONTAINING THE SAME
    Publication number: 20190176344
    Abstract: The present invention provides an underactuated mechanical finger capable of linear motion with compensatory displacement, a mechanical gripper and a robot containing such finger. The proximal phalanx of the finger includes a cam fixed on a linkage. Upon actuation, the linkage rotates the cam, which then drives a cam follower, which then drives an extensible part in the distal phalanx to extend the length of the finger, and therefore compensate the finger's height loss that would otherwise occur in the absence of the extensible part.
