We're talking two separate things, FRAME PERIMETER (Yes, it is a definition in Section 1.6) and the robot size as defined in <R11>.

The robot size is non-negotiable. Either you're in the box, or you're trying to fit in the box so you can pass inspection. It's that simple. 28" by 38" by 60" is the maximum starting size. No screw heads, bolt heads, or rivet heads excepted. See <R11>.

The Frame Perimeter, as defined in Section 1.6, is "FRAME PERIMETER – the polygon defined by the outer-most set of exterior vertices on the HOSTBOT (without the BUMPERS attached) that are within the BUMPER ZONE." Bolts and screws and other similar items are not counted--this is to facilitate tight bumper-frame connections.

If your frame perimeter is 28" by 38", and has bolt heads, welds, rivet heads, and similar items sticking out such that it will not go into the box, then you are not in compliance with <R11>. If your frame perimeter is less than 28" by 38" (many teams design 1" undersize in all dimensions), then your bolt heads, welds, and rivet heads can stick out up to that 28" by 38" rectangle on the floor.
