I think that's going to be true for most of us, regardless of design. I really expect (as I've written here before) that some robots are simply going to drive out from under their arms. A 'bot with an extended arm with a tetra on it is going to have a high polar moment of inertia in the vertical axis. I might have to buy a new video camera for the tournarment.
