Actuator

An actuator is a device that converts energy into motion. It takes a control signal—often electrical—and uses it to move or control a mechanism or system. For example, in a car, electric actuators can adjust the position of windows or seats. Actuators are essential in various applications, from robotics and automation to appliances and industrial machinery, enabling precise movements like opening valves, steering, or even moving robotic arms. Essentially, actuators help implement the commands from a control system, turning instructions into physical actions.
