Robot finger

The invention belongs to the field of robots, and discloses a robot finger which comprises a finger assembly, a power line mechanism and a driving mechanism. The power line mechanism comprises power lines, a power assembly and a winding wheel, the power assembly comprises a plurality of rotating wheels, and the winding wheel and the multiple rotating wheels are in tensioning connection through thepower lines; the finger assembly comprises a palm and fingers; each finger comprises at least two knuckles, wherein every two adjacent knuckles are rotationally connected through one rotating wheel,and the knuckle close to the palm is rotationally connected with the palm through the rotating wheel; the driving mechanism drives the winding wheel to rotate, so that the winding wheel drives the rotating wheels to rotate through the power lines, and the knuckles rotate. According to the robot finger, the rotating wheels between the knuckles provide rotating power through the power lines to achieve rotation of the finger,
