Re: Angled Bumpers, concave design

See Figure 8-1 in the 2017 Manual and description of Example following R01. Based on those figures and examples, we would like to know which rule the attached "concave" design might be breaking.

It took a bit of work to find the link, but the word link above links to what I think you're interested in. I'm not completely sure what I'm supposed to be looking at, but trying to figure it out, this is my best guess:

The blue polygon is your chassis frame, and the grey rectangles are segments of bumpers.

If this is the case, your design is right out. The FRAME PERIMETER is the smallest CONVEX polygon which includes all of your robot, excluding bumpers and bolt heads. In your case, the FRAME PERIMETER is a rectangle which includes all of your "maw". This rectangle is the one which requires 6" of bumper support at each corner. Most of the grey rectangles are inside the FRAME PERIMETER, and are not BUMPERS.
