As the width gets greater and the length less, the robot begins to approximate a 2 wheel drive robot (like a segway) and should be very close to having the absolute maximum possible turning force.
That's how we see the theory, at least. We'll let you know how it works in practice once we get it all together and give it a try, perhaps late next week or early the following week.

Exactly the same thing we are doing. It was the easiest thing to do, but prototyping this was really annoying and took me forever. But maybe I'm just dysfunctional.
Once we have the CAD/Inventor drawings done and machine the parts, it should be a simple yet effective design.
