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. An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
Robotics Planning. Robotics Technology-Actuators. Actuators, also known as drives, are mechanisms for getting robots to move. Most actuators are powered by pneumatics (a ir pressure), hydraulics (fluid pressure), or motors (electric current).Most actuation uses electromagnetic motors and gears but there have been frequent uses of other forms of actuation including NiTinOLmuscle-wires and inexpensive Radio Control servos.ost actuators are powered by pneumatics (a ir pressure), hydraulics (fluid pressure), or motors (electric current).
