This was my 2nd attempt in developing a line following robot using the Lego Mindstorms NXT 2.0 kit. It was much faster and accurate than my initial attempt and the power level of the motors were set to 100% in the straight line areas. The robot was made from a modified NXT 1.0 basic kit model with a color sensor attached to the front. The track was simply made from taping printouts of black lines together. The NXC programming language was used for programming the robot.
