[osofdz16]

The rule for the bumper says that a corner must have a least 8in to each side covered by the bumpers, it also says that a side smaller than 8in must mi entirely protected.
Here is the rule:
ROBOTS are required to use BUMPERS to protect all outside corners of the FRAME PERIMETER. For adequate protection, at least 8 in. of BUMPER must be placed on each side of each outside corner (see Figure 4-3). If a side is shorter than 8 in., the entire side must be protected by BUMPER (see Figure 4-4). A round or circular FRAME PERIMETER, or segment of the frame perimeter, is considered to have an infinite number of corners.

With this in consideration: Would a robot with a front size of 25in and an opening of 13in thus leaving 2 small sides of 6in, be legal? As the one shown in the image.
