Re: Fasteners extending outside the FRAME PERIMETER

Sorry to disagree with you again, Al.... I'm with Martin on this one.

By definition, the frame perimeter is measured within the bumper zone. That hasn't been changed in Update #6. The update only modifies the method by which you identify the frame perimeter. It doesn't modify any of the consequences of exceeding the (newly-defined) frame perimeter. (Such as <R16>, <G30> and by extension, <S04>.)

Rather than allowing some uncertainty about whether a protruding fastener in a pocket was sufficiently protected by bumpers to satisfy <R07A> (it probably would have been), and whether the frame perimeter would have had to follow the contour of that protruding fastener irrespective of the pocketing (this could have been true if the pocketing was intended for use by bumper fasteners only, rather than fasteners in general), I think FIRST opted to simplify everything and give a straightforward method for employing the <R07D> pocketing allowance.

However, with regard to the robot size limit—you're absolutely right. That constrains the total size of the robot, irrespective its frame perimeter.
