COMPUTER FUNDAMENTALS

Detailed explanation-1: -An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power.

Detailed explanation-2: -For example, servo motors, actuators that are electrically operated, are used to move the joints of robots and to change the direction of radio-controlled car by moving their tires. Power shovels and other construction equipment use actuators called pneumatic cylinders, which rely on oil pressure to extend and retract.

Detailed explanation-3: -An actuator is a device that produces a motion by converting energy and signals going into the system. The motion it produces can be either rotary or linear.
