Prosthetic devices and, more particularly, modular myoelectric prosthesis components and related methods, are described. In one embodiment, a hand for a prosthetic limb may comprise a rotor-motor; a transmission, comprising a differential roller screw; a linkage coupled to the transmission; and at least one finger coupled to the linkage. In one embodiment, a component part of a wrist of a prosthetic limb may comprise an exterior-rotor motor, a planetary gear transmission, a clutch, and a cycloid transmission. In one embodiment, an elbow for a prosthetic limb may comprise an exterior-rotor motor, and a transmission comprising a planetary gear transmission, a non-backdrivable clutch, and a screw.

A gripping device with linear actuation for a robotic arm for seizing and gripping Petri dishes and other light items. The gripping device has a support and first and second gripping arms slidably retained relative to the support by guide rods. A motorized drive mechanism actuates the gripping arms through an operating member that acts only on the first gripping arm. Through an interconnection mechanism, movement of the first gripping arm actuates a simultaneous and dependent opposite movement of the second gripping arm so that the gripping arms are movable between a slack position and a clamping position. The operating member acts on the first gripping arm through a resiliently compressible member, the distortion of which is measured to provide a clamping limitation mechanism.

The present invention relates to an elastic corrugated pipe single-acting cylinder-driven mechanical gripper with a series-connection loose-leaf hinge framework. The mechanical gripper consists of a palm and two flexible fingers or a palm and three flexible fingers. The flexible fingers are identical in structure, and each one of the flexible fingers consists of an elastic corrugated pipe single-acting cylinder and a series-connection loose-leaf hinge. Each one of the series-connection loose-leaf hinges has a hinge mandrel equipped with a torsion spring, and the characteristic parameters and pre-tightening angle of the torsion spring are optimally designed according to the features of a grasped object. The mechanical gripper is driven by the elastic corrugated pipe single-acting cylinder to generate a grasping force. The mechanical gripper applies to the grasping of fragile brittle objects, or grasping of objects with varying shapes and dimensions.

A workpiece conveying device capable of correctly positioning and conveying a workpiece that has a burr having an indefinite shape by means of a robot. A robot hand has first and second claws configured to move toward and away from each other. The first claw has a first contacting portion configured to come into contact with a lower surface of the burr, and a first clamping portion arranged at a front end of the first contacting portion and configured to come into contact with a main body of the workpiece. The second claw has a second contacting portion configured to come into contact with the lower surface of the burr, and a second clamping portion arranged at a front end of the second contacting portion and configured to come into contact with the main body. The first and second clamping portions cooperatively position and clamp the main body.

The present invention discloses a biomimetic bag opening device for an automatic filling line, comprising brackets left and right symmetrically arranged on the filling line for filling bags, the symmetrically arranged brackets moving in a horizontal relative motion respectively driven by a pull rod, a push bag plate facing the filling bag provided at a front end of the bracket, a row of gripper holes provided on the push bag plate in the upper and lower of the horizontal level respectively, two rows of grippers provided on the brackets behind the push bag plate and corresponding to the two rows of gripper holes, a gripper drive device driving two rows of grippers open or closed, and grasping fingertips of the grippers projecting or retracting from two rows of the upper and lower of the gripper holes.
