<R10> During the MATCH, the ROBOT will assume one of two operating configurations. When in each configuration, the ROBOT shall fit within the limits shown below (note: these limits are defined in reference to the ROBOT, not the FIELD).

NORMAL CONFIGURATION
Max horizontal dimension Rectangular space no more than 28 inches (71.12cm) by 38 inches (96.52cm)
Max Height 60 inches (152.40cm)
Max Weight 120 pounds (54.43Kg)
FINALE CONFIGURATION
Max horizontal dimension 84 inch (213.4cm) diameter vertical right cylindrical volume
Max Height 90 inches (243.8cm)
Max Weight120 pounds (54.43Kg)

So if a robot fastener does not fit within the sizing box which is designed to test the max horizontal dimensions of 28" x 38", the team will need to make some modifications to do so.

We already established that this discussion has nothing to do with the NORMAL CONFIGURATION limitations. I understand that nothing whatsoever (except for the allowance made for a some type of kicker) can extend past the 28x38 footprint while in NORMAL CONFIGURATION. This discussion is about the FRAME PERIMETER. The problem still exists even if you have 12" by 12" robot. Then your FRAME PERIMETER would be decided by your frame members within the bumper zone. Any bolts that protrude from the FRAME PERIMETER, but NOT the NORMAL CONFIGURATION would be "excluded from determination" of the FRAME PERIMETER. Thus, they would extend past the FRAME PERIMETER and be illegal, and they would not allow for identical bolts below the FRAME PERIMETER either.
