Servo (radio control)

In the context of radio control (RC) systems, a "servo" is a type of electromechanical device that provides precise control of angular position, velocity, and acceleration. Servos are commonly used in RC models, including airplanes, helicopters, cars, boats, and drones, to control the movement of various components such as control surfaces (like ailerons, rudders, and elevators), steering mechanisms, and other movable parts.
