Potentiometer useage in remote controlled mechanical arm
Potentiometer useage in remote controlled mechanical arm
(OP)
I have been working on a project building a mechanical arm and shoulder ending in a manipulator. I would like to control this using a frame mounted to my own arm with a rotary potentiometer at each joint. I'm better at the actual build of the machine than the building of circuits so I need some help on the setup of this. I want the mechanical arm to mimic the actions of my own arm using the pots in the joints and I'm using a flex sensor in a glove to control the end effector. Thanks!

So then you connect the wiper to the input of a servoamplifier/motor that moves an output shaft (connected to the slave arm) in proportion to the voltage at the input. The motor typically has a pot of its own on the output shaft that tries to minimize the difference between the input voltage and the slave shaft pot voltage by driving the motor.
R/C servos work similarly, except that the control signal is represented by the width of a pulse instead of a voltage.
That's grossly oversimplified. Get some local help.
