==Mechanisms==
* [[Servomechanism]], or servo, a device used to provide control of a desired operation through the use of feedback
** [[AI servo]], an autofocus mode
** [[Electrohydraulic servo valve]], an electrically operated valve that controls how hydraulic fluid is ported to an actuator
** [[Servo drive]], a special electronic amplifier used to power electric servomechanisms
** [[Servomotor]], a rotary actuator that allows for precise control of angular position
** [[Servo (radio control)]], a small, cheap, mass-produced actuator used for radio control and small robotics
*** [[Servo bandwidth]], the maximum trackable sinusoidal frequency of an amplitude
*** [[Servo control]], the use of pulse width modulation to remotely control servos
* [[Servo tab]], a small hinged device installed on an aircraft control surface to assist the movement of the control surface
