Re: How are you getting over the 4" bump?

But we have the "braces" (VAGUELY like fenders; our plywood prototypes looked like fenders, but the final ones are just tubes of aluminum defining the outline of the 'fender') just on the outside of each wheel. They are made of tubular aluminum and the "braces" actually hit the bump before the wheel, lifting the (8" mecanum) wheel up a little so it can just slide over the bump. The chassis is high enough that it doesn't touch the bump in the middle. So we go over 2 wheels at a time (budump, budump). It works.
(emphasis added)

Update: I believe I spoke too soon. At this point, it does NOT work. At least, it does not work with our plywood 'bump'. It worked great when tested on our 'chassis-only' bot, but with the extra weight of the actual bot, no dice. We're still thinking it might work with the steel bump, but if not, no big deal, we can just zip over the bridge. And we're going to be so busy scooping up balls and scoring that it probably won't matter that much. We hope.
