Actually, given that we're allowed FOUR banebots motors this year, there's a good argument for building a quadcopter to pick up the tubes and place them on the rack. It'd be the absolute lightest overall mechanism out there (mainly because it'd HAVE to be in order to fly properly).

I suggested it, but the kids thought I was totally whacko. Heavy sigh.
Maybe I can convince them to try it this offseason. It's actually not that hard.
