I wish I had time to post more on this right now, but suffice it to say there has been a lot of research on how humans and animals do this type of thing. Staying within a hallway without bumping into the walls is actual done by taking a mental (...) (25 years ago, 16-Nov-99, to lugnet.robotics)

(...) Fascinating, I tried the search but unfortunately nothing related turned up. Coincindentally, there's another thread on line following based on the conventional single black line. There is the suggestion that the line has to be somewhat (...) (25 years ago, 16-Nov-99, to lugnet.robotics)

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.

(...) 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)
