Abstract: A robotic hand includes a servo housing, a printed circuit board (PCB), a motor, a planetary gear transmission assembly and a plurality of claws rotatably connected to the servo housing. The motor is electrically connected to the PCB. An input end of the planetary gear transmission assembly is connected to an output shaft of the motor, and an output end of the planetary gear transmission assembly includes a helical gear shaft and a number of helical gears that are engaged with the helical gear shaft and the claws. The helical gears correspond to the claws respectively. One end of each of the claws is rotatably connected to the servo housing, and the claws are rotatable toward or away from one another when driven by the helical gears.
