Regarding IR receiver module, did you ever consider getting a 360 degree
coverage by pointing the module _up_ then adding a reflector above it
which will direct IR from all around into the detector?  A suitable
reflector could be a small cone made out of aluminium foil.  The apex
should point down and have an included angle of 90deg.

Hi Steve,

Good idea, no I haven't tried it (and, it would probably be very useable for
my application).

Of course you suggest it *after* I wire up my Robot...
