This is a line following robot that is controled by a PCB and compenents kit from that is based on David Cook's sandwich circuit. This robot can follow a black line on a white surface or a white line on a black surface. The robot uses differential steering. Its body is made from a radio shack project box I got from LineRider1 which I scraped for parts because it wasn't that adequate of a line following robot. I hope to put this robot in competitions maybe in the future. And I may build a LineRider3 but it will probably have a microprocessor of some kind so I can program it to follow overlapping lines and have more intelligence.

Problems: One problem was the first 9v battery I put it wasn't brand new or must of been a lemon. It didnt power the robot efficiently but I put a new one in and it worked fine. Also the biggest problem is I tried to use the motors from LineRider1 for this bot but the gear box was to stiff for this circuit to drive and it stalled the whole thing out. It wasn't until I changed the motors to the GM8s that the robot worked. I should have used them anyway because they came with the kit.
