Thanks, we probably have the largest panels in the nation (at least that we seen/heard of) and the unique material you speak of is our 1.5" pvc-foam core design which is extremely rigid while also extremely light.
Unfortunately, we aren't. We twice lost to the Beach Bots (330 - an incredibly strong robot, look for them to go far in Atlanta) in the semis and finals in LA and SD; repectively. And both times we took the first of three games from them only to have them win the next two... Grr. Our only regret about not going to Atlanta is that we wont be able to showcase our unique design and reaffirm our feeling that we have one of the best lifting robots in the nation. To all those teams going to Atlanta - Good luck
