An air chuck includes a chuck unit including a pair of fingers that capable of being freely opened and closed, an operation unit that includes an operation mechanism, which opens and closes the pair of fingers, connection mechanisms for attaching the chuck unit to the operation unit such that the chuck unit is freely attachable and detachable to and from the operating unit, and a locking mechanism that locks the pair of fingers such that the pair of fingers are capable of being freely opened and closed when the chuck unit is attached to the operation unit and such that the pair of fingers are not able to be opened or closed when the chuck unit is detached from the operation unit.

A grip apparatus is provided. The grip apparatus includes a first finger; a second finger configured to face the first finger, a first link configured to have a first end connected to the first finger, a second link configured to have a first end connected to the second finger, and a differential apparatus including a motor and configured to connect a second end of the first link and a second end of the second link. The differential apparatus rotates the first link and the second link in different directions when the motor is driven. The differential apparatus rotates the first link in a first direction when the second link rotates in the first direction by an external force.

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.

The present invention relates to an elastic corrugated pipe single-acting cylinder-driven mechanical arm with a series-connection loose-leaf hinge framework. The mechanical arm 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 arm is driven by the elastic corrugated pipe single-acting cylinder to generate a grasping force. The mechanical arm applies to the grasping of fragile brittle objects, or grasping of objects with varying shapes and dimensions.

The present disclosure provides a robot gripper, comprising a bottom plate (101), a side plate A (102), an intermediate plate (103), a side plate B (104), guide rods (105), sliding blocks (106), cylinders (107), spherical joints (108), pneumatic quick plug connectors, a connecting plate (114), racks (115), a gear (116), a gear shaft (117), a horn type switch support (120), detection switches (121) and a detection head (122). By adopting the robot gripper, the bottom plate (101) can be connected with six-shaft flanges of a robot together by connectors; a gripper arm can be designed to connect the connecting plate (114) to grip a hub according to different demands; and the opening and closing state of the gripper can be detected by the detection switches (121). The robot gripper has the advantages of low price, compact overall structure, large clamping force, strong stability and the like.

The present invention concerns an apparatus (100) for transferring a vial (200) from a first station (301) to a second station (302), comprising a stock (101) of vials in said first station, a mobile arm (1) provided with at least three gripping elements (2a-2d) movable between one another in a controlled way at least between a first and a second position, wherein the free ends of at least part of said gripping elements (2a-2d) have a magnet (5), and wherein the area of the polygon (P) having as vertexes said free ends in said first position is smaller than the area of the polygon (P) having as vertexes said free ends in said second position.

A gripping device includes a drive motor with a motor-current-monitoring or pressure-monitoring system, and a gear unit which can be driven by the drive motor. The gear unit has a worm gear stage driven by a rotatable gear shaft, which worm gear stage is coupled to at least one of at least two gripping element carriers which are movable relative to one another. A holding brake for blocking the gear shafts is arranged in a housing of the gripping device. The worm gear stage has a screw that is axially slidable towards at least one spring energy accumulator, so that, upon an increase in the flank pressure on the respective gripping pressure flank of the screw, the loading on one of these spring energy accumulators increases. The drive motor is so relieved of load in a gripping device in spite of a high gripping force.
