Martin,
As I look at your drawing, there are no fasteners in the bumper zone and so those dimensions (12 x 12) become the FRAME PEERIMETER. Therefore the fasteners at the bottom of the chassis extend beyond those dimensions. If this robot was placed in the sizing box, the fasteners outside the bumper zone would contact the vertical sides of the box before the frame in the bumper zone and would therefore not meet the definition (as I understand the rules at this date) even though the robot is significantly smaller than the sizing box.
