Barcode Scanner Based Line Follower

line follower

Brody thought it was high time we featured another robot project and directed us to his site: For his line follower bot he used an old barcode scanner he found cheap at a junk shop. The scanner has a 2088 pixel ccd linear image sensor. Several red LEDs are used to illuminate the image and the data is fed to an ATmega8. The wheels are then driven using two Sanwa servos modified for continuous rotation. He’s got a couple other projects on the site and I’m sure we’ll see more in the future.
