Perhaps I should state that this was based on last year's game and our derived requirements. Obviously different games will drive requirements; however, I find the raised front with appopriately placed CG works exceptionally well in maneuverability and stability. For instance, we were able to rotate in place while balanced on the bridge in Rebound Rumble.

I might be mistaken with the CG of the OP's drop center, as I was expecting a CG placed over the center wheels for optimum rotation. As you are aware, this is a huge assumption and changes the entire dynamics of the robot. Correct my assumption if this is not the case. Moving forward with this assumption, would the robot not require a forward vector to pivot to the rear 4 wheels when turning, thus negating the ability to turn in place?

I was also under the impression that teter-tottering was a design deficiency, but I now see how you could use it as an advantage.
