2017 Bunper Rules?

[aring2017]

Hello, my team was looking at the bumper rules at a design meeting. We couldn't find any gap restrictions except for the 6 inches that must be covered on each corner. Did you guys find the same? Last year there was an 8inch limit. If not could you reference where it's says so? We don't want to design our robot around a rule that might be clarified later and leave us in the lurch. Thanks!
