I'm planning to use colors, too, for a "follow the line" vehicle that I'm
building. I don't like the simple black line that is commonly used. If you
loose it, you don't necessarily know which way to go, and you have no clue
how far you are off the line. My current plan is to use a strip that is
black on one edge, and white on the other edge, with a nice gradient fill in
between. I'll make various pieces of these strips (straight, sharp curves,
light curves etc.) with my computer and printer. The brightness reading
directly translates into steering input. The darker it gets, the more you
steer to the right. The brighter it gets, the more  you steer to the left.
At a reading of 50, go straight.

There will be some intersting experiments. If you turn off the lights in the
room, will the vehicle move a little more to the right?

The next phase will be to embedd barcodes into the strip, to tell the
vehicle about its location along its course.


Wow- sounds really interesting. Keep us all up to date...

(...) Just for reference: The optical mouse pads made by Mouse Systems, and shipped with Sun workstations for a long time, used two detectors in the mouse. One used a red LED, and the other one looked the same, but was dark. I suspect it was an IR (...) (25 years ago, 28-Apr-99, to lugnet.robotics)
