PID Line Follower for EV3 (Part 2) – K Values and How to Improve Performance

The PID line follower is the ultimate EV3 line following program. It is mathematically complex, but it can compensate for a lot of errors and keep your robot right on track. It is a popular line follower to use in FLL or WRO. Previously, I taught you how to program a PID line follower. Today, I will demonstrate the line follower in action with my robot, Sirius, provide some sample K values you can try with your own EV3 robot, and discuss ways to make it more accurate and reliable. I will also discuss the practicality of using a PID line follower in an FLL or WRO competition.
