Wow, so thats what it looks like.

If all else fails does it drive like a normal 6WD?
Yes. The turntable is powered by a BaneBot 545 motor in a 64:1 planetary gearbox, which is not easily back driven. If we do not power the 545 motor, the robot drives like a standard 6 wheel drive robot. We noticed that turning ability was somewhere in between a narrow and wide configuration, but closer the narrow configuration.

How much is the center wheel lowered? Related: how much does the front rock up and down?

How are you controlling it? (I'd probably use a standard arcade joystick and the x axis of a second joystick to set the angle to rotate the drive base)
The center wheel is lowered 1/16th of an inch.

We are controlling the drive with a steering wheel and one joystick. The steering wheel controls the powered turntable, and the joystick is in arcade mode, controlling the drive like a normal 6 wheel drive.

Here's more info on how it works: http://www.chiefdelphi.com/forums/sh...5&postcount=15
