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?
How about linear actuators? I've heard they are kind of slow. This bot may go up to 5 miles per hour.
Maybe I'll need a powerful stepper?
Or perhaps a simple geared motor with limit and position switches?
