This was my second Line following robot. After lots of runs I made some changes to the position of the IR sensors. I used the IR TX pair combination for the line sensor. Four Sensors are placed in one line which tracks any line whose angle can be +/- 90 degrees and two more sensors in a second line at the extremes sides of the robot which can detect angles greater than +/- 90 degrees.
