Judging from the lively discussions in an accompanying thread on line followers, it seems that
following a single black line is far from being a trivial matter.

It seems to me more natural to be keeping within a hallway (or the walls of a canyon in the Star

I would really like to know who or how was it decided that bots should follow a single line in
the first place. Is it just to save on black paint or the number of light sensors?
Any clues?
