That appears to be the max size of a drive base according to last years rules, right? For a competition bot, would you scale that design down somewhat in order to add a protective structure around the outside? or would you just rely on the fabric bumpers? It would seem to me that the channel used on the outside would bend/dent easily, and no amount of suspension will keep a Mecanum drive operating correctly if one or two of the wheels are suddenly bent at some odd-angle. The video looks very nice indeed, and I can't wait to see what the drivers can do with a bit of practice
