What is this type of circuit called?

What is an electronic circuit called that would work like this (for example):
you have a knob the circuit and a servo. you turn the knob and the servo mimics the motion of the knob.
basically I am looking for schematics an information I can use for the control of a simple telemanipulator. just a simple (relatively) copy cat mimic circuit. the controller moves and the manipulator moves. any Ideas what to look for?
is there a name for this type of controller?

The elements for doing that are.
The (set point or input) potentiometer you refer to its supply is called the reference, usually 10V
This signal (arm of this pot) would go to the + input of the amplifier.
This amplifier must have the capability to drive the motor in question! (Power op-amp)
The mechanical output would have another potentiometer fed by the same reference as #1
This feedback potentiometer arm of this pot would go to the – input of the amplifier closing the loop.
This is a very simplistic explanation.
In real world there are some delays to deal with, and complex damping algorithm before it works properly.
Strip chart recorders use all this electro-mechanics.
There are many of the mechanics and electronics in computer disk drives, very cheap for reverse engineering.
This question and answer is an analog version.
Computers uses both, analog and digital, stepper motors, VCR also have quite a few with gears, very educative.
Hope this properly answers your question
