For some reason, bots are compelled to follow a single line. Whereas
humans typically keep within two parallel lines when they drive.
However, when they are inebriated, humans may try to emulate the bot,
often with disastrous results.
There exist line tracking algorithms for bots using 1, 2 or even 3 light
sensors to follow a single line. None appears to be entirely
satisfactory. Humans, on the other hand, seem to be able to stay within
parallel lines pretty well with just a pair of visual sensors coupled to
a central processor.
I wonder if bots were made to follow parallel lines the way we humans
do, would just 2 light sensors be necessary and sufficient for the
purpose? And would the bot move smoothly without jerking to and fro like
a druken driver?

I wouldn't say the human eye is just a 'visual sensor' of the Lego type... it's more like a very advanced camera... and the 'central processor' is also much better than any supercomputer at analyzing that kind of input...

| (...) Yes, but I believe that in most cases the CPU for a human has a few more KB of RAM than the RCX. (...) Another difference is the range on visual sensors - eyes can detect lines meters away, and even distinguish 2 lines inthe same field. (25 years ago, 16-Nov-99, to lugnet.robotics)
