2012 Bumper rule gray area

[Japper]

[R01] states, "The robot must have a Frame Perimeter that is comprised of fixed, non-articulated structural elements of the robot. The frame perimeter of a robot is defined by the outer-most set of external verticies on the robot that are within the bumper zone which is between 2 and 10 in. from the floor."

To me this reads like it is only covering the side perimeter of the robot and not the bottom as I am trying to see if we can incorporate an extra set of wheels on a swing arm under the robot to allow us to lift our (2" from the floor) bumpers over that metal curb in the middle of the field.

Any thoughts on that?

It definitely seemed like the rules were missing the whole "definitions" section that they've had in the past, where things like frame perimeter and bumper zone were defined.

Yep, I spent a good half hour searching for it Saturday afternoon. The unobvious definitions seem to be scattered throughout the blue boxes.

How the bumper zone is calculated with a swing arm changing the height from the floor sounds like a question to submit to the GDC.
