On this topic, I know it's been asked before, but...
Is there a formula for the optimal offset of the caster wheel's axle from
the pivot point?
BTW, the relatively new 3u pin without friction
(http://www.peeron.com/inv/parts/x202) plus the freestyle wheels
(http://www.peeron.com/inv/parts/6248) or model team wheels
(http://www.peeron.com/inv/parts/2695) make a nice two-wheel caster with a
minimum of parts.

Thanks everybody for the answers, but i think i will give up with the
caster... The robot will be very heavy... i think it wont work.. I will go
to a synchro drive aproach...
Thanks.
