摘要:
An articulatable member includes a distal end, a proximal end, an actuation member, and a constraint member. The actuation member extends from the proximal end to the distal end. The actuation member transmits force to bend the articulatable member from a neutral position. The constraint member extends from the proximal end to the distal end. The constraint member may have opposite ends that are fixed to the distal end and the proximal end. In one embodiment, the constraint member follows a helical path along at least a portion of the articulatable member from the proximal end to the distal end. In another embodiment, the actuation member follows a helical path along at least a portion of the articulatable member.

A method of making an actuator having a complex internal shape includes providing a core of a shape that defines an internal cavity of an actuator; molding an actuator around the core, wherein the core occupies the internal cavity of the actuator, the cavity having an opening; generating a pressure differential between an exterior surface of the actuator and the internal cavity of the actuator, wherein the external pressure is less than the internal pressure, to expand the actuator cavity; and removing the core through the opening of the expanded actuator cavity.

The invention relates to an assembly device (1) having an assembly rail (2), comprising a base slide (3) and a spacer slide (4) for replacing a gripper tip (5) of a gripper finger (6) for a robotic system. The base slide (3) comprises a first fastening means (30) for fastening a gripper jaw (7) of the gripper finger (6) and the spacer slide (4) comprises a second fastening means (40) for fastening the gripper tip (5) such that the gripper jaw (7) can be fastened on the base slide (3) by the first fastening means (30) relative to a longitudinal direction (L) and the gripper tip (5) can be fastened on the spacer slide (4) by the second fastening means (40) relative to the longitudinal direction (L). According to the invention, the base slide (3) and the spacer slide (4) are arranged to be movable against each other between a locked position (VP) and an unlocked position (EP) along the longitudinal direction (L) such that, in the locked position (VP), the gripper tip (5) is locked to the gripper jaw (7) and, in the unlocked position (EP), the gripper tip (5) is unlocked from the gripper jaw (7).

A modular gripper assembly having body with a yoke structure (44) defined at one end thereof and an actuator at an opposite end for reciprocally driving a piston assembly (58) within the yoke structure (44). A pair of opposable jaw members (49) having through-slots (48) formed therein are provided within the yoke structure (44) and coupled to the piston assembly (58) by a cam pin (47) so that at least one of the opposable jaw members (49) pivots when the piston assembly (58) moves within the yoke structure (44). The jaw members (49) are removable and interchangeable.

Adjustable stoppers for limiting the angle at which pivotal gripper jaws (200) are opened. The stoppers include a stop block (205) and at least one stopper pad (207) which is made from a shock absorbing material such as urethane. The stoppers are secured to a pivotal one of a pair of gripper jaw members of a parts gripper and positioned to abut the other of the pair of gripper jaw members. Stoppers which are provided with two or more stopper pads of different lengths are reversible and can be used to adjust the angle at which the jaw members open.
