It sounds like a much more fun challenge if you limit the mechanism to using only one degree of actuation! I can think of a few approaches, but they all inevitably end up using more hardware than simply hooking up two motors to drive the rollers.
This was a good lesson we took from last year; if you minimize the degrees of freedom of a manipulator you can make a system that is
in theory simpler than one that uses more actuators, but the final result typically ends up being more complicated than simply using multiple motors. Still, that won't stop us from trying... manipulators that utilize minimal actuators have a nice appeal.
