Actuator or actuator is a mechanical device to move or control a mechanism or system. The actuator is activated using a mechanical arm which is usually driven by an electric motor, which is controlled by an automatic media controller programmed including a microcontroller. An actuator is an element that converts analog electrical quantities into other quantities such as rotation speed and is an electromagnetic device that produces movement power so that it can produce movement on the robot. We sell quality actuators at low prices.
