No point in continuing to argue this one, we just disagree. We'll see once I've got [S]better[/S] prototypes on my end.

Maximum width of robot including bumpers is 36 inches. Maximum wheel-to-wheel distance is more like 26. You have more than a foot of room to misaim... if you fall of the bridge in the process of crossing it, your driver did something horribly wrong, no matter how good your software is.

So, uh, you're saying that we could be blocked from crossing the bridge if two robots independently break down in front of two separate bridges and are too heavy to be pushed out of the way? The odds of that are so negligible that it's hardly worth discussing.

Or you could just not design for the ridges. It's not like they're necessary to cross for most robots. (If all three robots on an alliance are regularly crossing midfield, think of the time wasted!) I haven't tried the wedges, but I'm 99% sure they'll work. Remember, any drive built to cross the ridge needs an elevated chassis to avoid high-centering anyways, so all you're adding is extra metal plates.

I'm not assuming you'll be there, I'm saying you can get there. Maybe there have never been good tank drive defense robots at my regional, but I kind of doubt that. Pushing mecanum drives is indeed fairly easy, but it's not pushing them around that's the hard part of defense, it's maintaining the push.
