Abstract: The present disclosure relates to an anti-shake method of robot and a robot thereof. The method includes: receiving at least one motion-controlling instruction from a main control unit, determining whether a servo performs the motion-controlling instruction, obtaining a target angle and a current angle of the servo upon determining the servo is not under a control of a main control unit, determining whether the target angle and the current angle is within a fault tolerance range, terminating the servo upon determining the target angle and the current angle is within the fault tolerance range. As such, the shaking of the robot may be avoided when the robot performs actions, so as to reduce power consuming and to extend stand-by time.

Abstract: A servomotor includes a control circuit, an electric motor, a harmonic drive and a sensor. The control circuit is connected to the electric motor and used to control the electric motor. The harmonic drive includes an outer casing, a wave generator, a flex spline and a circular spline. The wave generator is driven by the electric motor. The flex spline is sleeved on an exterior of the wave generator and located within the circular spline and engages with the circular spline. The flex spline is connected with an output member that is used to output power, and a post is arranged along a rotation axis of the output member. The sensor is arranged within the outer casing and used to detect an angular displacement of the post. A method for controlling the servomotor is also provided.

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. An output end of the planetary gear transmission assembly includes a cam having a number of protruding portions in a circumferential direction thereof. Each two adjacent protruding portions are spaced apart from each other by a space, thereby forming a curved circumferential surface. One end of each of the claws stays in contact with the curved circumferential surface, enabling the claws to be rotatable toward or away from one another when driven by the cam.
