the way the ultra sonic sensor is set up is a good idea

I feel the way they set up the light sensor is a little to far out

we are gonna have to place the ultrasound or light sensor under three inches if we are following the inside walls, but thats an individule decsion. we could use a code similar to the wall following code in the romba project.
