We're about as rookie as a team can be and while we're making progress and have had some great help from other teams there are some areas we're still struggling with (even at this late stage!).

We have a set-up where we're trying to tilt a horizontal panel (32" x 23") through a range of about 90 degrees with 5 pre-set stages (front 1: fully tilted, front 2: partially tilted, flat, back 2: partially tilted, back 1: fully tilted). We have a chain underneath the panel connected at each far side that runs through a tensioner on each side and then to what we want in the middle to be a motor with a sprocket. Everything on the mechanical side is figured out and working smoothly but we have no idea what kind of motor and controller to use that can be limited to that range of motion in labview and how to attach the motor properly to the sprocket. We have quite a few different types of motors on hand from the original kit as well as First Choice including several types of window motors. The load is not too great as the panel is balanced well in the center. The chain is basically pulling the panel around a pivot point.

We could really use some pointers to first tell us if this is even possible with a motor/controller/sprocket and then secondly, if so, what is the optimal motor/controller pair to use.

Thanks in advance for any tips!
