Hi, people I have carried out an investigation into line following, a task that all respectable bots are expected to be able to do. Diagrams often show the idealized zigzag path that the robot is supposed to take when following a line. However, I (...) (22 years ago, 26-Sep-02, to lugnet.robotics)

Very interesting (and good) work. It may be useful for you to post the program used, because (as you said) it can make a difference in the results. However, I have to disagree with part of the conclusion: "A line follower using a single light sensor (...) (22 years ago, 26-Sep-02, to lugnet.robotics)

(...) You can improve the single sensor program considerably by having it go straight when it sees an intermediate value, which is what it would see when it's right on the edge. So, you have two cutoffs, LOW and HIGH. If light value is less than (...) (22 years ago, 27-Sep-02, to lugnet.robotics)

It might be worth trying to increase the area that the light sensor is seeing by putting some kind of a lens in front of it. If the sensor could see (say) a roughly circular region 3 centimeters across then numbers you'd read between the 'white' and (...) (22 years ago, 27-Sep-02, to lugnet.robotics)
