But I understand what you are saying though. But why would you want a robot with a CG + acceleration that would allow rocking in normal situations? Is there too much variance in when it does or does not teeter to be able to predict what axis the robot will turn about?

We chose this design for stability reasons. We always sit on our rear wheels. Likewise we always turned about the same point.

I guess it is just design intent.
