Robot Design: Frame Perimeter?

[DonRotolo]

I can't say; I think the rule is pretty clear:

FRAME PERIMETER – the polygon defined by the outer-most set of exterior vertices on the ROBOT (without the BUMPERS attached) that are within the BUMPER ZONE. To determine the FRAME PERIMETER, wrap a piece of string around the ROBOT at the level of the BUMPER ZONE - the string describes this polygon

Got any string?

If any ball can go more than 3" inside that string, it's not allowed.
