3 unusual facts about Servomechanism


After Burner II

Like OutRun, another Sega arcade game, After Burner II came in several versions, the most famous being a large, servo actuated, sit-down cabinet which resembled a cockpit and moved according to the motion of the plane onscreen.

Cyclic/collective pitch mixing

Conventional model helicopters use three independent servos to manipulate the swashplate.

Heberlein brake

This causes the brake clips to be applied on individual wagons, assisted by a servo system which makes use of the rotation of the axle.

Motion control photography

Early attempts at motion control came about when John Whitney pioneered several motion techniques using old anti-aircraft analog computers (Kerrison Predictor) connected to servos to control the motion of lights and lit targets.

Saunders-Roe Princess

While the prototype aircraft had advanced (but conventional) hydraulic controls, S-R intended production aircraft to use an analogue system based around electrical servos with hydraulic final control actuators.

Self-parking system

The basic components of such a system are a rear-mounted camera, servo-motors for turning the steering column and activating brakes, and a micro-computer based control system to perform the parking maneuver.
