Servo

Servo motors are small devices that have an external shaft. This axis can be moved to different positions if a coded signal is sent to the servo. As long as there is this signal at the Servo input line, it will keep its axis in a specific position. When the signal changes, it causes the servo to change the angle of the shaft. In practical applications, the servo is used in remote-controlled airplanes, cars, and robotics. These engines have an extremely small size but are strong enough for their size. Servo is very useful in robotics. They have a micro mechanism, a built-in control system, and a great deal of power compared to their size. The energy consumed is proportional to the mechanical load it receives. That is, the less load we give to a servo, the less energy it consumes.
