Re: How can we drive on this new floor?

We found out a few interesting things today. we mounted 4 of the rover wheels on the back of our 2008 lowered center 6wd and drove it on the FRP. the weight is biased pretty far back so the front never touched down. right away you could push it around really easy like they did at the kickoff. after wearing out a few batteries driving around, the wheels got a a significant amount more traction. we then put a small scale in front of the front bumper and told the driver to push as hard as he could without spinning. it pushed with about 35 lbs of force until the wheels broke loose, when the scale went down to about 19 lbs.
This type of drivetrain (long 6wd, lowered center) drives like a smaller version of a wide robot as long as it stays on the rear 4 wheels turning was pretty easy but we haven't hooked up a trailer yet.
