hmm. I'll have to think about this, but I'll bet, with a little work and a
couple polarity switches, you could make an AB skid steer. I think it would
take some fancy wiring (like the 18v thing) and some precice gearing, but
think about this: You could connect the drive motor output to a polarity
switch, and connect the polarity switch to the steering (like Chris did) and
the output would go to the motor on one side. Then, when the drive stick is
pushed forward, the motor goes forward. Move the 'turn' the stick, and the
motor stops or goes backward. (same thing for the other side)
That's just the concept. It CAN work, but it won't be easy.

Here's something interesting. Oh, wait, you don't like to do the same thing
as anyone else...

damn. I wish I was closer.
