(...) That's why I suggested a solution that works in all cases. It's not much harder than your solution either. (URL) Robert Munafo (25 years ago, 15-Jul-99, to lugnet.robotics.rcx)

(...) This is my inspiration for adding on-the-fly init code, btw. RoboTag uses two seperate robots, and it turns out that my friend -- the source of the second mindstorms kit -- has a light sensor which reads about 10 "darker" than mine. (25 years ago, 15-Jul-99, to lugnet.robotics.rcx)

(...) Wow. I feel I should point out that experimentally my method works 100% of the time. :) On the other hand, mine is a special-case application: the light sensor is used to read color values from a surface, which presumably will have very little (...)

Matthew's program takes one reading at initialization time to determine a baseline value. Any reading that falls 7 units below this is assumed to be a dark line. I take a somewhat more conservative approach, taking 10 readings over one second and (...) (25 years ago, 15-Jul-99, to lugnet.robotics.rcx)

(...) The author claims it has very good spectral properties, but I have no way of testing that. The only other reference I have found to it on the net is from a group at the University of Salzburg, who state that it performed well in their tests. (...)
