Let's Make Robots!

Simple Map robot

Hello!

 

I have arduino duemilanove, ultrasonic sensor , geared motors with wheels. I wanted to make a room mapping/ navigating robot to go from one place to other.

 Even if it doesnt learn the environment in real time ,is allright. I just want it to store a simple map of square room and go from one square tile to the other.

 

Please guide me.
