H-Bridge Motor Control for DIY Servo

I'm building a DIY servo for steering Yard Gnome. I'm testing some things out while I wait for the 24VDC 30 rpm 41 in-lbs gearmotor I ordered to arrive.

I'd like some advice on my controller.

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?
