Need help with a steering algorithm...


This may be more of a general programming question than arduino specific; I guess the principles apply to all programming languages.

Steering problem


I don't know if any of you have seen my project that I posted just earlier on today (http://letsmakerobots.com/node/23660), but I have already ran into a problem with the servo steering. As it says in the project, the servo at 0 or 180 is barely turning left or right.

Do any of you know of any genius ideas as to how to fix this ?? Or perhaps even a way or rebuilding the steering entirely for use with a micro servo?


Recommendations for steering

I'm building a yard bot. The initial blog is posted for my Yard Gnome already.

This robot will steer like a car, with one drive motor pushing two rear wheels, and a two-wheeled steering mechanism up front.

I'm looking for recommendation for how to automate steering on this thing.

Is there an affordable servo that is strong enough?

Should I build my own servo?
