By considering both the note in TU 6 and this...

<R16> During normal operation no part of the ROBOT shall extend outside the vertical projection of the FRAME PERIMETER, except as permitted by Rule <G30>.

I believe the intent is that "minor protrusions such as bolt heads, fastener ends, rivets, etc" outside the bumper zone are treated the same as if they were in the bumper zone as R16 references the definition. I think that the restrictions allow robots to be equally inspected. Please note that axles, structures, kickers and other frame parts are not part of the exclusion. Thank you, GDC.
