Abstract: A connection assembly for holding a support member in position includes: a base defining a receiving hole to receive an end portion of the support member, and a guiding hole in a lateral surface thereof, which communicates with the receiving hole; a fixing block; a locking member slidably received in the guiding hole and slidable between a first position where the locking member is engaged with the support member so as to hold the support member in position, and a second position where the locking member is disengaged from the support member; and an actuating member connected to the fixing block and the locking member, the actuating member being configured to drive the locking member to move between the first position and the second position.

Abstract: A finger of a robotic hand includes a phalanx portion including two phalanxes rotatably coupled to each other, one of the two phalanxes being rotatable about a rotation axis with respect to the other one of the two phalanxes; and a stopper structure including a first stopper member connected to the one of the two phalanxes and a second stopper member connected to the other one of the two phalanxes. The first stopper member extends around the rotation axis, and a circumferential space is defined between the first stopper member and the second stopper member and allowing the first stopper member to rotate together with the one of the two phalanxes in a predetermined range.

Abstract: A finger of a robotic hand includes a phalanx portion including at least two phalanxes rotatably coupled to each other, a rotating member that is rotatable with respect to the phalanx portion, a rope having two opposite ends respectively connected to one phalanx and the rotating member, a rotating cam driven by a driving device and having a lateral surface that stays in contact with the rotating member, the rotating cam being configured to push the rotating member to rotate the rotating member in a first direction, and an elastic member connected to the rotating member and configured to apply a force to the rotating member to rotate the rotating member in a second direction.
