All in the pictures.
The biggest one that sort of concerns me (and please chime in Chris) is whether we should drive the turret directly or if we should drive it using a sprocket / chain setup. The reason why this decision isn't clear to me is because it AFFECTS PROGRAMMING. Chris, what is our plan to position sense, if any, if the the motor directly drives the turret? Or maybe we should let go of trying to do autonomous shooting and camera tracking all together?
