Orient both RCXs so that they are pointing towards the ceiling. Set the RCX
transmit power level to high (default is probably low power); there's
probably some Lejos function to do this -- all it requires is setting one
bit in an I/O register to 1. RCX signal will bounce off the ceiling. Verify
this will work before building RCXs into your model. This works in my office
with 10 foot ceilings

Have you tried a mirror? Infrared light IS light !

| In terms of power requirements and battery life, has anyone here actually quantified how much of a difference that makes? Its a damn good idea - as long as you have white, and relatively flat ceilings. If you dont want/are not able to reposition (...) (21 years ago, 6-Aug-05, to lugnet.robotics.rcx)
