Geoffrey,
It is not my own plan of attack, so to speak, but it
seems to me that there might be advantages to a
florescent strip as opposed to a single bulb type
light. Well, there might be if your camera system can
differentiate alignment of the strip. That is to say
that if your light strip runs due east/west, then you
have only to look at the light and have a 50% chance
of knowing exactly which direction east is. That means
that your other landmarks are instantly easier to
use/identify, or might be.
Its all down to how your camera system works. I don't
think there would be too much advantage to it if you
are simply using light detectors with low resolution.
Anything much lower than a camera would seem too low
to detect the direction of the strip (but I could be
wrong). My first thoughts would be to use a camera and
the I2C interface for RCX from mindsensors.com...
Once you can identify lights vs. bright spots on the
ceiling, I wouldn't think the programming has to be
more complex than that.
Cheers

| I take it you are thinking about using the CMUCam or some similar system with some level of intelligence on board the camera processor. After all -you are really not going to be able to shift the amount of data required to process on board the RCX, (...) (19 years ago, 9-Dec-05, to lugnet.robotics)
