kinematics

[Mikejkd]

Just getting ready to build one of these for fun and since its been a while since college I am looking for a good kinematics program. Is there any free programs out there or do I have to spend some cash?

Thanks

PS. I saw some posts that have a % for ackerman, isn't ackerman an angular mesurment?

% Ackermann is a ratio to perfect Ackermann angle.

150% ackermann is 4.5deg ackermann when perfect steer calls for 3deg. and so on.
