Re: <R08> Section M
Thanks for posting a question, Craig. Many teams (mine included) will be interested in the response.
I agree 3/4 x 5 inch plywood supported at two or more points per segment is plenty strong, and many teams used that approach in conjuction with cantilevered axles in previous years. <R08-M> appears to prohibit that approach this year, but hopefully the GDC will clarify that. My guess is that some kind of structure/frame, itself securely mounted in a fixed location w.r.t. the chassis at approximately mid-bumper height, will be required to contact the entire length of each segment of the BUMPER backing plywood.
What I'd like is for the GDC to provide some guidance for teams, and for robot inspectors, on what qualifies as structure/frame. Is a strip of 0.062" thick aluminum too flimsy to qualify? What about angle with a similar thickness? Or maybe 0.125" thickness is needed? What about other materials, such as plastic and wood -- can they qualify as structure/frame?
