Last year, our robot was completely surrounded by standard bumpers. We built them to specification, with holes drilled in the 3/4" plywood to make weight. As of
this Q&A that is no longer legal. Our bumpers are
just as specified <R08> and cover the perimeter of the the robot base completely, with the addition of some embroidery fabric. They weigh a little bit more than
16 pounds. Has anyone else run into this problem?
