Here is a link to Gus Janson's SteerBot
(http://www.lugnet.com/~726/SteerBot) which I think you will find has great
maneuverability as well as a tight turning radius (~6"). I have replicated
it several times in the past 2 months for my group's line following event.
After getting the original built, I was able to make several tweaks that
improved speed in straights but not improve turning radius (I tried but
failed to add Ackerman effect to the rack and pinion setup). The latest
version of this robot built by Gus actually has a smaller footprint and even
tighter steering setup (See this picture:
http://pix.houseofdistraction.com/2002-10-12b/4.html). All in all this is a
nice and small platform for a car steering robot, even without the Ackerman
effect. Anyway...I hope this helps you.
