Actually, you don't need true line of sight from the RCX to the tower. The
IR light is sufficiently strong enough that reflections from walls,
etc. can still control the RCX and vice versa. (Try this with the RCXCC
"joystick" utility.) As for the PalmIII, I've got one of those and would
love for a utility like RCXCC ported over.

| Good point, I also had the brief idea to construct something like a IR-mirror which scatters the IR but with only 2 motors the mechanics become a nightmare. I looked into the palm III and its actually more difficult than initially thought: Lego is (...) (26 years ago, 14-Feb-99, to lugnet.robotics)
