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?

       The primary motivation is because a hallway is wide and a
line is narrow.  This means that when the 'bot is on a line it has a
reasonably good idea where it is.  Also, in maze following, when it
reaches an intersection it can see all of its various choices without
randomly bumping around for five minutes.  And even after five minutes
of randomly bumping around, there might still be one option the 'bot
missed.

        It will certainly be interesting to continue to see the
various solutions in both areas.

Thanks for the thoughts.

I'm not sure if it's been done before, but I'm now making a playing field where the bot will have to
keep within two black lines using 2 RCX light sensors to see how it compares to conventional line
following. I'll include a  T-junction to see how the bot will react in actual practice.

Nothing like trying it out to see if it'll work.

(...) You are right that with one stationary light sensor, line following is not a trivial matter. Change the constraint and it starts to become a little more trivial... we're just splitting the problem by focusing on both the mechanical and (...) (25 years ago, 17-Nov-99, to lugnet.robotics)
