We used a mechanical linkage to do it. It was actually 4 wheel Ackerman (don't know if this setup has a different name). The front wheels would turn one way and the back wheels would turn the opposite way, while the inside and outside wheels also compensated for the variable radii of the turn.
We did this for Lunacy and it was really cool when it was working however we had some massive issues with some couplings we were using (the tolerance needed to be tighter than we thought) which prevented us from ever getting to really show it off in competition.

If you're doing it to win, you're doing it wrong. Teams who truly understand why they are doing what they do will win Chairman's simply as a result, an added benefit. The award isn't the goal. It's the impact you create, and the results you see. - dcarr [more]
