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.

Abstract: A thumb structure includes a proximal phalanx, a distal phalanx rotatably connected to one end of the proximal phalanx, a fixing member connected to the proximal phalanx through a first ball joint, a linking member having opposite ends that are connected to the distal phalanx and the fixing member through a second ball joint and a third ball joint, a first actuating assembly to drive the proximal phalanx to swing in a direction of a first degree of freedom, and a second actuating assembly to drive the proximal phalanx to swing in a direction of a second degree of freedom.

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.
