    This algorithm allows your robot to determine its own binary threshold for detecting the line.

      How to Use This Algorithm
      Set up your IR emitter/detector sensors and place all of them facing the concrete. Get a reading, then place all of them on the white line and get another reading. Now you have two readings for each IR. Find the average of each, and set them as the threshold for each.


        read IR1c //read on concrete
        read IR2c
        read IR1w //read on white line
        read IR2w

        (IR1c + IR1w)/2 = IR1thresh
        (IR2c + IR2w)/2 = IR2thresh

    Infrared line detection with 2 IR
    This algorithm allows your robot to follow a white line.

    2 IR on MOBOT course

      How to Use This Algorithm
      Set up your two IR emitter/detector sensors so that one is on the left of the line and the other on the right. As long as neither detects the white line it means your robot is following the line. If either detects the line, the robot must make course corrections.


        read leftIR
        read rightIR

        if leftIR detects line
        then turn robot left until not true

        if rightIR detects line
        then turn robot right until not true

        if neither IR detects line
        then robot goes straight
