Excuse the tabloid heading, but when I investigated undocumented behavior of
the Scout last night, I hit onto some surprising features.
See the preliminary report on LEGO on my mind.

Highlights:
- overview of RCX-triggered responses
- wipe the dust off your Code Pilot, the Scout emits bar codes!

See: http://homepages.svc.fcj.hvu.nl/brok/legomind/robo
and select Scout from menu.

Looks like Eric got his batteries recharged at Mindfest!

Hmmm, if we have pre-programmed abilities in the Scout, maybe
we can make networks of scouts to make a distributed
control system?

Think of a conveyor system with a scout driving the belt, another
dumping things on, and a third taking things off.

This is an awful lot like the Crickets we saw at the Media Lab!

Cheers,

Additional observations:

- at the start of any program, the Scout emits barcode 004 which triggers a
'steam puff' sound in the Code Pilot (if it's in record mode). The Scout
seems to emit no other barcodes (but motor left, motor right, motor float
and puff) during the built-in programs.
- showing a valid barcode on a computer screen doesn't allow a Code Pilot to
read it, probably because of the interfering screen refresh rate (tried up
to 100 Hz).
- refresh rate may also interfere with a pulsating spot on the screen (to
simulate bar code) but I didn't test it
- running the Scout's light sensor over a backlighted bar code on regular
paper didn't give any response. Didn't have printable transparant sheet. So
far we don't know how to tell when the Scout recognizes a bar code anyway.
- the built-in programs distinguish between three light levels. If the
program is started at a medium ambient light  level, a strong light will
trigger the LED indicator and an 'up' sound while darkness will also(!)
trigger the LED indicator and a 'down' sound.

Hi Eric,
thanks for digging into the Scout and revealing all those amazing features!

Last Sunday at the Mindfest I met a Lego representative who confirmed that
there's much more than most of people image packed into the Scout. He told
me they're going to release a textual interface to program it, and they will
probably do sooner than what they originally planned.

BTW, he knew all the names of the people the regularely write here, and web
pages, concepts, works, software and everything happens here. Just to give
you some examples, he came to our table and asked Marco Beri and myself if
we plan to release a new version for our legOS emulator, and is not that
emulegOS is a very widespread tool! And we talked about Laurentino Martins
and his deep experience with Cybermaster, and he mentioned many others.
So now I'm sure THEY DO READ LUGNET, and they pay a lot of attention to what
happens here.

March 7, 2003 - The SCO Group filed legal action against IBM in the State

UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
