Perhaps, its a possibility,
My team probably will. Most of the designs we've come up with have an arm to stack and thus can fold down. Also we have a design of a giant box, like the ball gatherers from last year that could fit under the bar and of course internally stack boxes.(A really cool method
) I think every team could but I don't think it is that necessary. My team is just afraid of the moving wall that we can't get past. (we don't want to build one though
too boring) Remeber pieces of the robot can always start vertically and then fold down. I've heard the horror stories of Chiefdelphis robot two years ago ^_^.(i wasn't there) They're all terrified of them now.
good luck!
