Line follower robot with one light sensor. Lego NXT.

Useing one linght sensor to follow an arbitrary line. The line can be curved with very large curvature, and the width can be less than 1cm.
Actually the robot will work more smoothly on smoothly curved lines.
The obstacle senseing was failed in this test, however.

I have wrote an article to explain the methodology to program it, go and reference at http://www.wretch.cc/blog/myandychen/23114583

I think you'll need more than one led. I did one in my electronic lab, I had four on the bottom, four on the side, two front, two back, it follows line and parallel park.
