Topic: my line follower (Read 2 times) previous topic - next topic


I had successfully completed my 2nd line follower with arduino
its not that good though but for beginner i believe its ok...   ;)
but i face a problem... if u see the video closing you will see my robot sways and zigzags too much.... is there someway i can make it go straight and faster.... i used 4 sensors... i have currently reduced my speed becoz if i increase speed it zigzags even more violently. now i am completely overhauling this robot to make a new one any suggestions to avoid this problem in new robot?
thanx in advance  :)


It needs some kind of a look ahead so it knows how much it needs to turn to get to the target. The zigzag is caused by overshooting the target. Find a way to make it not overshoot, and you should remove most of the oscillation.


yeah wanted to knw how to reduce that overshoot...


Perhaps you can use the PID library to control overshoot and improve line following?

It's in the Playground: http://www.arduino.cc/playground/Code/PIDLibrary

Sorry I can't be of more help, I haven't used it myself yet.


5kb is lots of space.... :o
