Re: Rule clarification - trailer recessed

BUMPER 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 BUMPER PERIMETER, wrap a piece of string around the ROBOT at the level of the BUMPER ZONE - the string describes this polygon. The BUMPER PERIMETER may extend up to, but cannot exceed, the maximum ROBOT volume constraints defined in Rule <R11>.
"Outside" is not defined; rather <R18>D says, "D. The Trailer Hitch must be located on an outer edge of the ROBOT structure such that it may easily connect with the tongue of the TRAILER (attached to the TRAILER)."

Thus, the GDC has to be asked in the Forum (when it opens) what "outer edge" in <R18> means. I suspect their answer will be, "On the bumper perimeter" - but we don't know that now.
