One word: wow! Jack, you certainly came up with a substantial amount of
information, especially considering that you only had a short time for your
project! You have a lot of good theory on your site that I'll have to study,
especially your GPS "ping" routine.
Something I thought of when reading your report: do you suppose that, in
addition to providing out-of-range notification for the PC and indicating that
the datalog is ready for upload, the ping routine could provide a source for
the proximity sensor reflection data? In my experience I haven't had to mount
the RCX pointing straight up (it can still receive messages even facing away
from the tower), so hopefully I can use the RCX IR in conjunction with the
light sensor.

| (...) Sure. I had mine detect overhead objects since that is the way the RCX was pointing. (...) I found I had a longer range with the RCX pointing up instead of away from the IR tower. In theory, the ping routine will turn the RCX towards the IR (...) (25 years ago, 25-Aug-99, to lugnet.robotics)
