Actuators
Actuators are mechanical devices that convert energy, typically electrical, hydraulic, or pneumatic, into mechanical motion to effect a change in a system. They serve as the 'muscles' of automated systems, performing tasks like opening valves, moving robot arms, or adjusting flight surfaces…
