The Vision Command camera was great - until you discovered it had a cord :)
and thereby understood that Lego *faked* the robot in robotics inventions
commercial...)
This is my very first post and so I don't know if this idea is new, but I'm
suggesting that until Lego understand they have to release an IR-connected
camera, that you can
1) Use any cel phone to eavesdrop, for example making a rover that reacts
to something "interesting" by turning the phone on, dialing a number (or
recording) i.e. sending sound via the microphone, and when the receiving end
hangs up, times out after a certain time and turns the phone off.
2) The robot could call an automated answering service, which sends a
message thru the mobile's speaker, or even the time of day if you call that
number! oo - a clock on wheels which gives you the time in Andorra at the
clap of a hand! (Or two, as the case may be :)
3) The same would of course be true for the phone types which have the
ability to take, send and receive pictures.
4) Two robots with a mobile each could possibly send modem noise (at low
bitrates, probably) to communicate digital information. One of them could be
stationary and sit by the IR tower, thereby allowing the other to stray far
away (the next country, even!) and still send info to your PC. (Which could
be running some sort of AI program - in effect _providing the faraway robot
with that intelligence_.)
The cel phone with the largest, most clickable buttons (and fewest button
clicks to reach a certain function), and the best/loudest sound quality,
would probably be the one chosen for this.
To press the buttons, the obvious method would be using Cams. Those familiar
with the Ultimate Builders Set could put a long axle on Motor Module 3 and
put a couple of cams on it, using the Rotation Sensor to keep track of how
many degrees the axle has turned.
If a given sequence of 4 or less buttons is to be pressed, you just have to
put them at 90° angle to one another, the first to be pressed at 0°, the
second button at 90° a.s.o, and then just turn the axle 360° to press the
4-button sequence. So you program the sequence by putting each cam in the
correct angle. In that case, you could use a Cam and a Touch sensor to stop
rotating after 1 rev.
If you use the "Motor Saver Trick" in RIS 2.0, you could do 2x4-button
sequences with 1 motor, 8 cams and a touch sensor.
I just got this idea from my Coffee Pot, so when I have some pictures to
show what I mean I'll reply to this.
Sending info via cel phones is the only way that I can see which could
expand the robot's capabilities beyond 32K memory. (See above)
What do you guys think? Anybody know the perfect cel phone model for this?

| I don't know about other places, but here cell phone service is expensive to use as a robot communication method. Perhaps a "personal radio" (They have a range of about 2 miles) would be better, and data could be transmitted through tones. ----- (...) (22 years ago, 4-Jan-03, to lugnet.robotics)

| (...) It's even more than that really. Sending live video over IR really isn't feasible - there isn't anywhere near enough bandwidth to do that. What you *REALLY* want is to have enough on-board CPU power in the robot to process the images locally - (...) (22 years ago, 4-Jan-03, to lugnet.robotics)
