need simple line following robot schematic

[555 timer chip guy]

I need a simple line folowing robot schematic for a research paper. It needs to be simple so I can build it fast. I do not need the robot design only the circuit schematic.

i *think* this guy used to have the circuit diagram for his "sandwitch" robot on his site:
http://www.robotroom.com/Sandwich.html
but i can't seem to find it now.
have a look around his site. maybe it's still there and i'm just missing it.
even if you can't i have herd his book is quite good. you will get the diagram there.

dunk.

You could check out his book from your local library. I'm sure it has the schematic.
