Mechanical or electrical devices that convert energy into motion to control or move systems and mechanisms.
From Latin 'actuare' meaning 'to set in motion' or 'to activate', plus the agent suffix '-ator'. The term emerged in the mid-20th century as automated control systems became more sophisticated in industry and aerospace.
Actuators are the muscles of the mechanical world - they're what makes robots move, airplane wings adjust, and automatic doors open. From the tiny actuators that focus your smartphone camera to the massive ones that control jet engines, they bridge the gap between digital commands and physical action.
