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?

Sterylite6000 is a large and somewhat unusual robot.  Originally it was designed to use only six servos.  This worked resonably well, but did not get good ground … Read more

Guibot's mothers shaver

Today I got a parcel with the post.

Wondering what it was, it was quite a surprice to find what I imidatly recognized as being Guibot's mothers shaver.

Guibots mothers shaver

wrt54g as robot brain

Andrey Mikhalchuk demonstrates how to hack a popular wifi router to have an rs232 interface (or two). The openwrt project allows us to actually use that powerful hack. Andrey did what few people did before: he added a micro servo controller and TING robot's done!
