Your frame as it stands now is illegal according to the bumper rules. In these rules, the ROBOT PERIMETER is defined by a string around your robot. Hence the inward facing segments would not be located on the bumper perimeter. And since all BUMPERS must be attached to a solid frame member located on the ROBOT PERIMETER, and since all corner vertexes on the ROBOT PERIMETER must also have at least six inches of bumper on either side, this is illegal.

This situation is solvable though by making the two inner facing chassis rails perpendicular to the other frame rails.
