Abstract: A spatial crossed-axis transmission mechanism includes a rotatable driving member, an actuating member, and a support member for fixing the driving member and the actuating member. The driving member comprises a first end surface adjacent to the support member, and an Archimedes spiral groove is defined in the first end surface of the driving member. The actuating member includes an end surf adjacent to the support member and a sliding shaft on the end surface of the actuating member. The support member defines a straight groove passing therethrough, and the sliding shaft comprises an end that extends through the straight groove and fits into the Archimedes spiral groove.

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 robotic finger structure includes a proximal phalanx; a middle phalanx rotatably connected to one end of the proximal phalanx; a distal phalanx rotatably connected to one end of the middle phalanx and defining a distal phalanx opening in a front side thereof and at one end adjacent to the middle phalanx; a connecting rod having opposite ends that are rotatably connected to the proximal phalanx and the distal phalanx, and an actuating assembly to drive the middle phalanx to rotate with respect to the proximal phalanx. The connecting rod includes a first angled segment having a first recess facing a back side of the middle phalanx. When the distal phalanx is flush with the middle phalanx, the first angled segment passes through the distal phalanx opening, and a first end of the distal phalanx opening extends into the first recess.
