If I have a 6 wheel drive robot and my CG is on one side or the other of the middle wheels, then I do not need the other set of wheels to remain flat on the bridge. If I stick something out between the wheels that are not needed (and hanging over the edge of the bridge) I will remain flat with respect to the bridge the entire time. Once balance, we retract. This update gives me the ammunition I need to fight for this mechanism.

What we really need is a clear and concise ruling on this bridge balancing device.

There is a reason many of us are asking the questions so specifically. The extra clarification in the latest update makes it clear to me that if my robot looks like it is not raising its bumper relative to the surface that it is on, then we are good.

The fact that so many of us are not in agreement means we may need further clarification.
