Those reflectance sensors are not made for detecting objects, they are
usually used in something like a shaft encoder. So the 5mm is the useful
range that they will have for that application. Not too useful for
object detection.
Digikey 1-800-digikey has those types of (shaft encoder) ir detectors.
As far as I know, if you want to detect objects at a useful range, you
have to build them out of detector modules and a dual oscillator. Radio
Shack has a schematic of one that you can get by fax but I don't have
the number with me now. Let me know if you want it.

PS We (my associates and I) have put some assembly code for using the
miniboard as a slave to the handy board on the user contributed code
page. I don't have that address with me either but LMKIYWI.

| I don't have the Flynn book with me currently, but I coulda sworn that I read about the Rug Warrior (or some other robot) "wall following behavior". I thought that this was accomplished by IR obstacle detectors. I was also under the impresion that (...) (28 years ago, 10-Dec-96, to lugnet.robotics.handyboard)
