Oh my goodness... I was simply admiring the robot until the question about the bumpers came up.

My concern was initially over rule R8 part I, "Bumpers must protect all exterior corners of the bumper perimeter" as the corner between the trailer hitch section on the angled side piece is a corner and, with bumpers on only one side, would not be protected. However examining the reference figure 8-2, this design would be in keeping with the figure specifically referenced by the rule. I'm not up on all my bumper Q&A's, so perhaps there has been an answer to this already... but ARE the rear corners of the robot adjacent to the trailer hitch in figure 8-2 protected by bumpers? Do they have to be? If that hasn't been answered you might want to get an answer on that one as when a drawing is inconsistant with a wording, the wording takes precedence.

My other concern would be R18 E, concerning the trailer bumpers contacting the robot bumpers before the trailer tongue contacts the bumpers. It may be that this happens in this design, it is hard to tell without seeing it with bumpers on and a trailer attached.

I am assuming that with bumpers on the front of the robot that 2/3 of the bumper perimeter is covered?
