Re: Bumpers sticking out 1" beyond frame perimeter

As I read OP, this could be perfectly legal. I'm ignoring the other three sides (where the bumpers are against the "frame" and seem to be exactly what the rules envision).

How I read it: On the front side, the bumpers would be located 1" forward of the "frame". Then, at least once each 8", there is a (substantial) protrusion from the "frame" which is part of the robot (not the bumper) that supports the bumper. These protrusions then define the FRAME PERIMETER. As long as the FRAME PERIMETER is still no more than 120" after including these protrusions, this would be a legal FP/bumper combination. On the other hand, if the protrusions are part of the bumper (that is, they come off the robot when bumpers are changed), they are illegal, as the hard parts now extend beyond 1" from the FRAME PERIMETER.

In a practical sense, this is the same as the bumper brackets used on many West Coast style drives, just on the front face rather than a side face.
