Small triangular mechanical claw applied to chess piece grabbing and robot

The invention belongs to the technical field of robots, and particularly relates to a small triangular mechanical claw applied to chess piece grabbing and a robot. The small triangular mechanical clawapplied to chess piece grabbing comprises a driving unit, a rotating disc, paws, a transmission unit and a base, the rotating disc can rotate under the action of the driving unit, the number of the paws is three, the two ends of the transmission unit are connected with the rotating disc and the paws respectively in a rotatable mode, the base is connected with the driving unit, and the middle section of each paw is connected with the base in a rotatable mode. According to the small triangular mechanical claw applied to chess piece grabbing in the technical scheme, the driving unit can drive the rotating disc to rotate, meanwhile, the rotating disc acts on the paws through the transmission unit, and due to fact that middle sections of the paws are connected with base in rotatable mode, thepaws can rotate along the
