We did indeed test this, by placing the wall away from the perimeter so that it contacted only on the tiles, and then ramming the 315G (Turning Point division finalists, 6m base with ramps) robot into the wall. I think we have footage of this too, and it should be in our documentary when that finally comes together.
I hear your point, and I understand where you’re coming from. Given Amonton’s First Law and all, it seems that pushing an 11lbs wall should be pretty much the same as pushing an 11lbs robot with mesh/banded traction wheels, which is difficult but not impossible. However, I think that the weight of this wall causes it to sink into the field tiles more than any normal robot with wheels does. This deformation, I think, means Amonton’s First Law doesn’t directly apply, and so the 11lb wall is even harder to push than an 11lb robot.
A last point on a different note: we don’t disagree that an 8m basebot with some specially designed anti-wallbot features (wedges/hooks/etc.) could be a potentially effective counter.
However, a bot designed expressly to counter the wallbot is, in our estimation, a bot that can’t score well anyways. Seeing as we still have 2 4m basebots, our strategy would likely be to simply gang up defense on your partner after deploying our walls. Even if you are able to move a wall out of the way, I imagine your partner will find it exceedingly difficult to make use of that new window of opportunity. This might bring the game to more of a 0.5v1 or something, but I will assert that the advantage remains with the wallbot alliance.
