Can I use the Pololu Jrk Motor Controller with Feedback to control a window motor and use it as a steering servo for a power wheels. Basically can I programt the controller to run directly off a RC receiver and to have a center point, then be able to turn the motor both directions about 90 degrees? I hope this makes since.
Yes: for input, the jrk can be directly connected to an RC receiver.
For output/feedback, the jrk can control the position of a motor as long as you have an analog feedback signal that represents the position of the motor. Do you have a potentiometer that turns when your motor turns? If so, the jrk can control the position of that motor if you configure it correctly.
The feedback and input scaling settings of the jrk will let you set the center points.
