Actually, I had in mind a tank-drive setup, which can do a nice turn-in-place (with suitable wheels/tires) and driving arcs can be achieved by just driving each side at a different velocity.
If it's not my drawing you're referring to, then nevermind <grin>.

heh, the strategy in the picture did give me ideas

. It happens to work perfect for our forklift drivetrain(easier to drive in an arc).
- Not going with Ackerman steering, so turns in place will be just fine.

The steering system in cars is called Ackerman steering. The front wheels have to turn at slightly different angles such that the if lines drawn perpendicular to the plane of each wheel and through the center of the wheel all meet at a single point, the center of the turn. This is a pretty good article:

That is very good information, however it doesn't help me with my problem as I am not using ackerman steering. Also, it doesn't give any mathematcal equations which is what I was looking for. Thanks anyway.
