Thats a cool idea using only nuts and bolts...
My team has had our frame welded every year for as long as I can remember...and then we have skeletons of welded frames from even before that lol

I can see the advantages:
no cracked welds
perfectly straight members
extra rigitity...

our robot is all crooked :|
because there were so many small parts to weld together this year...
but it still drives straight as an arrow =D
