Detailed explanation-1: -Actuators use an energy source – such as electrical, compressed air, or hydraulic pressure – and a control signal that can be manual, an automatic electronic system, a fixed mechanical system, a software-run system or a robotic control system.
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 component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a “mover". An actuator requires a control device (controlled by control signal) and a source of energy.
