Hello. We are struggling to follow a black line using a simple one sensor PID line follower. I believe that the problem is that in the SUV box design, the color/light sensors are actually a couple of centimeters BEHIND the midline of the robot. As a result, the robot gets caught in an endless loop. It sees too much white (too far to the left in this case) and so it begins to turn right. But because the sensor is behind the midline, as the robot turns right, the left sensor sees still MORE white and tries to correct even more. This all equals an endless loop of turning right and failure.
Has anyone encountered similar? Any solutions?
