| | | Does anyone know how to do drift correction? I have tried 4 different ways, but they all don't work. Is it a difference in wheel circumference? Or is it something with the programming? I drive for 5 seconds, then check the rotation sesnor values, If (...) (25 years ago, 3-Dec-99, to lugnet.robotics)

| | | | This will not work. Imagine a straight line that you want to follow. Drive for 5 seconds, allowing to drift to one side or the other.
