We built the first prototype and the competition drivetrain both in the same six week build season. It weighs just a bit more than a standard 8WD because of the pneumatic actuation. Here's a link to what I mean: Grasshopper Drive System
I had a great opportunity to talk to a couple of people on your team about your drive train, including manufacturing and maintenance. The insight was invaluable. If we decide to do it next year and improve upon it, we'll definitely send you a heads up with any of our new findings. From what I saw it was the best blend of simplicity, maneuverability and immovability. Who knew it was based upon a concept that was put out 3 years ago by the Killer Bees?

The only thing about the whitepaper I don't quite understand is the 'elastic tensioning'. Could you explain?
