Mike,
You should add one more element to your excellent picture
The wood backing of the bumper sits on top of the bolt head without any kind of indention. In other words, the bumper is not firmly backed by the frame.
Quote:
<R07> The entire length of the BUMPER backing must be supported by the structure/frame of the
ROBOT (i.e. the backing material must not be in “free space” between or beyond
attachment points) (see Figure 8 – 3).
