488 accomplishes this by using omni wheels on the corners. This style is shown in Madison's preso on FIRST Drivetrains... http://www.chiefdelphi.com/media/papers/2037
A variation of this I've seen on a few bots (45-2007) uses high traction wheels in the center and middle and lower traction wheels on the remaining corners. I'm pretty sure they used no wheel drop in this config. http://www.chiefdelphi.com/media/photos/28857

Yep... this year, team 45 is also using a 6wd without a dropped wheel in the center. All 6 axles are on the same plane, and all 6 wheels are 2008 Kit Wheels. The middle two wheels have been lathed down a bit and then a traction wheel tread has been riveted on. This makes the middle wheel about 3/16"-1/4" larger in diameter, compared to the outer wheels.
(edit...
Oh... by the way... team 45's 6wd uses only 3 different custom fabricated parts this year (not including bumper mounts). All of these parts can be made with a band saw and drill press. Stop by the pit in Atlanta and the kids will give you a tour.
