An actuator is a type of motor that is responsible for moving or controlling a mechanism or system.
It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. The most common type of actuator is powered by air and is called a pneumatic cylinder or air cylinder. This type of actuator is an airtight cylinder, typically made from metal, that uses the stored energy of compressed air to move a piston when the air is released or uncompressed. These actuators are most commonly used in manufacturing and assembly processes. Grippers, which are used in robotics, use actuators that are driven by compressed air to work much like human fingers.
