Line following: Learning the track with encoders

[Nexo]

Hello everyone!
I've been reading that is possible to use magnetic or optical encoders in order to "learn" or "record" the track. Do you have any idea on how to do this?
Thanks in advance!

If your robot can already follow the line, then the track can easily be derived from the movement commands you gave to the motors. There is a matter of filtering and compressing the data, but this is really up to experimentation and depends on particular hardware anyway.
