Re: Frame perimeter "minor protrusions"?

I agree with Alan. It sounds like the gusset plates are behind the bumpers, so they would define the frame perimeter and the slight protrusions would be allowed in the bumper zone.

Two things to keep in mind:

1) Make sure the gusset plate + bolt heads don't push the bumpers out enough that you have more than 1/4" gap between the bumpers and the c-channel along the rest of the bumper length, or the bumpers will be considered unsupported and need support every 8 inches. If they do, you are allowed to place small relief areas in the bumper plywood to clear the bolt heads.

2) The bolt heads can protrude beyond the frame perimeter, but they still have to be inside the maximum allowed dimensions of the overall robot (they still have to fit in the sizing box).
