Actuator systems are devices that convert energy into motion, enabling machines and equipment to perform specific tasks. They can be powered by various energy sources, including electricity, hydraulics, or pneumatics. Common applications include robotics, automotive systems, and industrial machinery, where precise movement is essential. These systems typically consist of an actuator, which generates movement, and a control system that directs the actuator's actions. Examples of actuators include electric motors, hydraulic cylinders, and pneumatic actuators. By controlling the position, speed, and force of movement, actuator systems play a crucial role in automation and modern technology.
