LineRider1 is a two wheeled differential steering line following robot. LineRider1 follows a black line on a white surface by using photocells and a krypton bulb that flashes using an interval timer. Also LineRider1 uses two relays to control its twin gearbox that correspond to the photocells. LineRider1's gearbox is set for a gear ratio of 203:1 for more torque. I had one problem and that was the photocells when they recieved light from being reflect off a white surface they kept running even when they got on the black line, but I fixed this by adding the interval timer. LineRider1 is powered by 16 AA batteries.
