The present invention relates to a gripper (500), for example for lifting and lowering a block, comprising one or more arms (540) having a damped self-centering mechanism (570) at a distal end thereof. The damping self-centering mechanism attenuates the contact force received thereon and facilitates self-centering of the damping self-centering mechanism relative to the block as the arm is lowered through the aperture in the block. The mechanism further includes one or more rods (575) at a distal portion of the one or more arms, the one or more rods being actuatable between a retracted position allowing the grabber to be lowered past a bottom end of the block and an extended position allowing the one or more rods to engage the block, the one or more rods being movable between a retracted position allowing the grabber to be lowered past the bottom end of the block and an extended position allowing the one or more rods to engage the block. The damped self-centering mechanism is configured to extend past a bottom surface of the block when the grabber is coupled to the block.
本发明涉及一种抓取器(500),其例如用于提升和降低块体,该抓取器包括在其远侧端部处具有阻尼自定心机构(570)的一个或更多个臂(540)。该阻尼自定心机构减弱其上接收的接触力并且在臂降低通过块体中的孔时有助于阻尼自定心机构相对于块体的自定心。该机构进一步包括位于所述一个或更多个臂的远侧部分的一个或更多个杆(575),所述一个或更多个杆可在缩回位置和延伸位置之间致动,所述缩回位置允许抓取器降低经过块体的底部端部,所述延伸位置允许所述一个或更多个杆接合块体,所述阻尼自定心机构被构造成当抓取器联接到块体时延伸经过块体的底部表面。
