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

If there is any drift, you will now be off the line and point in a direction that is not parallel to the line. Now (...) (25 years ago, 3-Dec-99, to lugnet.robotics)
