MakeBlock - Line Follower

Purpose:

To use the line following sensor so that the robot can follow a black line and correct itself when it goes off track. The line follower uses light to detect a black line on the surface below the robot. It has two sensors, one on the left and one on the right. When both detect a black line, they return a value of 0 to the the robot. When the left side does not detect black, the sensor shows a value of 1, when the right side does not detect black, the sensor shows a value of two. When both sensors do not detect black a value of 3 is sent to the robot.

Procedure:

  1. Connect the line-following sensor to port 9 on the robot.
  2. Copy the sample code. Test the sample code on the Ranger Test Pad.
  3. Figure out what is wrong with the code. Fix it so that it will track the line the entire way around.
