Brilliant take. Especially if you use some sort of roller-coaster-tire style mechanism vs linear ways, which just aren't going to stay aligned.
It would need a position and feedback system outside of the current "servo and home position" method, because even with closed loop motors, the distance traversed isn't exact. We need a cheap, easy way to get accurate-ish absolute position (1-3cm), maybe acoustics and phase-based?
