Re: How to build good bumpers
OK, I guess it is time to weigh in here...
In 2014 I decided to test the rules since so many teams had problems making good bumpers. I gave the rules, the cloth, plywood cut to size and a stapler to a couple of freshmen and two moms who wanted to help. I gave them no further instruction except to make them look like bumpers from previous years. They did a marvelous job. They stapled to one edge as proposed above, inserted the noodles (without fasteners or tape), stretch the fabric and then had the students lean on the back as the fabric was stapled. That little bit of squeeze does not change the dimension but does get the fabric tight.
As to why compression was not allowed, we know from experience that the full dimension of the noodle gives the best reaction to a robot to robot hit. Remember that round, hex and star shapes have been allowed in the past. It is the dimension that is important. The rules were modified to allow dimension lumber ("solid, robust wood") to make it easier for teams that have issues obtaining plywood. We just know that plywood backed up by robot frame with 2.5" pool noodles give the best protection. Having been around at a time when robot hits could put a team out of competition due to frame failure, bumpers help keep teams playing as long as they are able.
