[Robotgroup] High torque servo

[Paul Atkinson]

You could also support the moving part on an axle and then use the servo to
drive a gear that drives the axle. This way the servo would not be
supporting the weight.

There are some interesting soft cover books at some of the (radio-control)
hobby stores called "Control Systems". They give some pretty good pictures
and sketches of ways to use servos to connect to and move things.
