Line Follow Robot Tutorial
MOBOT 2006 Robot Competition
Without further ado, watch the video!
The line tracking is done with two photoresistors, using a case-based three state program to decide which way to turn.
Design in CAD
Feel free to drag around the interactive CAD file:

Now I added the omni-wheel and photoresistor sensors.
Spacers and a back copper plate was added. Those holes in that back plate are for servo wires to pass through.
Now I add both 6V 1800mAh NiMH batteries.
Wheels and a second battery are added.
Then I connected the no longer sold Cerebellum (PIC16F877) microcontroller to the top of the four spacers. Pikachu is added. And it's turned on so that's why its glowing green.
I just thought this lights-off shot looks cool . . . mmmmm 4000 candela LED's are great!
And a bottom shot.
A close-up of the LED and photoresistor.
