Advanced Vision Concept [help!]

It sounds like you are trying to use a motor as a servo. If you can use a hobby servo, your job will be a lot easier. If the Kinect is too much for the hobby servo, servo-ing a motor isn't overly difficult. It is a matter of comparing your current position to your desired position and compensating.

First figure out how you are going to measure that position. Do you need continuous rotation, or is there a range you can limit yourself to? How will you know where zero is? This will help you decide between a potentiometer, an encoder, or something else.

Then decide on a way to use that information to drive your motor. Jaguars have several advantages over Victors here. They have much much better low end response, which is important when the position is close. Victors can't do a good job of nudging here. Also, when driven over CAN they can perform all of the control loop on board for you. Then all you need to do is tune the parameters and then send new position set points periodically.
