Servo Motor Applications
• Servos are used in radio-controlled airplanes to position control surfaces like elevators, rudders and ailerons.
• In robot manipulators or operating grippers.
• Cruise control of automobiles
• Electronic devices such as DVD and Blu-ray Disc players use servos to extend or retract the disc trays
