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

Yeah, that's what we did. At least I think it is - I couldn't figure out how to describe it, and you've at least made a stab at it. 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.
