If it passes the Robot section of the manual (all of it), it's legal.

Yes we have a back up plan, our team has become quite good at working and building the basic two-wheel drive chassis and drive train so we've got that to fall back on.

found a couple of cad drawings, what did you mean by "the Nothing" is that a typo or a gearbox, please save the ignorant.

I believe that Ian is referring to the "Nothing But Dewalts" whitepaper that you can find here:

Guys i would highly suggest sticking to your back up plan, not to say that you can not do it but you only have 5 and a half weeks left. If you want to explore swerve drive then do it in the off season. It requires a lot of custom machine work and a lot fo customization. Seriously consider not exploring this drive system.

I agree with many of the above posts. A 'swerve drive' is potentially quite usefull, but it is a much better off-season project for your first time out. Our team (33) tried to build one for 2005 and it was abandoned after our first regional due to unforseen complications (including drivers not having nearly enough practice.) If you want some good technical tidbits on the little quirks we found, you should PM our mentor Jim Zondag.
Good luck!
