RoboFly 96
Quite a number of people wrote to us yesterday about The San Francisco Chronicle running an article about robotic flies with cameras. Pretty cool looking thing - capable of flight, with four wings - although the whole steering thing still needs be resolved, apparently.

David Brin has been pointing out that privacy is going away, because of things like this (causing people to flame him because they think Brin is advocating the loss of privacy, rather than simply predicting it). What's the use of PGP when the fly in the corner is recording your passphrase?
Brin advocates making the lack of privacy democratic: not only can the authorities spy on the public, but anyone in the public can spy on the authorities. No cop would get away with beating a confession out of a suspect ever again, not with hundreds of cameras following his every move.
I don't much like the surveillance society, but I'm afraid that it's coming, and our only choice is to let everyone be a watcher as well as a watchee, or to have a police state the likes of which have never been seen before
For those who think we can pass laws against roboflys, yeah, right. The things will soon be practically invisible, as Moore's Law means that they'll halve in size every couple of years. Laws will be ignored. There will be "arms races" as techologies for detecting micro-spy devices competes with other technology for foiling such detection.

The movie you're asking about is Runaway [imdb.com]. Huh- another Michael Crichton movie! I like his stories.
It's interesting that you mention that movie, because a lot of the concepts in it are becoming feasible now. Runaway had floating surveillance cameras, "lock-ons" which would track your car and attempt to blow it up, and smart bullets that sought out particular heat signatures. Not to mention the nasty little spider robots.
These roboflies could certainly handle some of the tracking and surveillance.
And companies are looking into ways to disable automobiles from a distance for police departments. A robot deployed from a police car in front of the offender futzes up the electronic fuel injection or ignition. Sucks to be you!

Anyne know of Kafka's Panopticon? That's where we're heading.
The Panopticon was a cylindrical prison, walled to the outside, but open/bar-doored to the inside. There was a watch tower in the center of the prison yard that shone bright light through the bars of all of the cells, lighting them up for the watchman to see.
There was a single watchman, with a sniper rifle, and the only punishment for misbehavior was execution. Prisoners sat in their cells, not able to see the tower or other cells well, due to the bright lights, and not aware of wether or not the watchman was looking at them or not.
The sense of potential observation, coupled with the occasional gunshot (for effect) eventually makes a watchman unnecessary, since the fear of being caught results in 'appropriate' behavior.
Once a society feels that it can at any moment be watched, it changes it's behavior patterns. We would become slaves, behaving in accordance with what is expected instead of what's natural and normal.

Re:Needed feature: gyroscopically stablized camera (Score:1)
I was thinking maybe some sort of helicopter-style thing is going on here. (Ie, helicopters get their forward thrust by tilting forward slightly and letting the rotors move them in that direction.) If the fly had a spinning gyroscope inside it, then when the fly tried to tilt the gyroscope with respect to itself, the fly would actually be the one to tilt. The gyroscope would tend to remain in the same orientation.
This way, the hovering fly tilts forward (or backward [or sideways?!]), and its beating wings would carry it in that direction.
Of course, this is all one freaking big intuitive leap, probably off an even bigger, freakier cliff.

Now the average tropical daylight solar availability is much lower, around 1800 W/m^2
The best cells for efficiency are not
flexible enough to use on the wings, and
are pretty dense. Lets just assume that it is possible to find such a cell, and that it has an efficiency comparable to Silicon (~9%) even though we know they won't work either. Oh, you can forget that weight estimate of 43mg they gave too. Mylar wings aren't going to collect power.
Now with my wild-ass guess of 20mm^2 for the upper surface area, we get about 3.2mW total available power. But wait, that is for a fly sitting flat still with every bit of its surface area perpindicular to a bright tropical sun. Once those wings start flapping and turning, any part that is more than 60 degrees from the sun will lose power completely, and any lesser angle will still mean significant loss of efficiency.
In operation, outside in daylight, I'd expect the fly to be receiving an average of around 1mW. Indoors, an order of magnitude lower (0.1mW).
Never say Never, but certainly not in the next decade.

In the case of the micro-mini 747, the air molecules aren't scaled down so their fluid behavior would be different. Also, the molecules that make up the steel aren't scaled down either, thus their structural properties would be different.

2) They claimed it is solar powered. Now, I *really* have trouble imagining a solar power collection system providing enough power to actually make it fly. I believe plants have the most efficient solar energy collection and conversion systems around (I could be quite wrong on this, actually), and I've never seen a flying plant. No biological fly uses solar power. I can't believe this thing is going to fly purely on solar power, and I really question how they are going to put ANY power plant on the thing so small and yet power everything that needs to be powered:
* Processor (and it will probably be quite a processor!)
* Propulsion system
* Video camera
* Transmitter
* Receiver (gotta be able to update its directions, eh?)
* Some kind of energy storage system, as if it is supposed to go indoors, in rubble, etc., or work at night, it won't be able to be purely solar powered. This of course means that it will have to collect more than 100% of its energy requirements to "bank" the extra for when solar isn't available.
Up to the point the point where I saw "Robofly will be powered by the sun", I thought it was just some interesting research that may or may not lead anywhere near its original goal, but upon seing that it was to be solar powered, I'm starting to think it sounds more like fraud. Or a reporter who got something VERY wrong. Personally, I'd find any energy STORAGE system that could propel a tiny flying machine for more than a few seconds very, very facinating.

Processor: 1mw is a very small amount of power for a processor. For reference, I believe some of the Pentium II class chips are running around 15W. 15,000 times as much. Not a whole lot can be done with 1mw of power other than your watch. Keep in mind, your watch isn't trying to keep its own weight in mid-air, but rather just counting the oscilations of a quartz crystal.
A 1mw transmitter is a very small amount of power OUTPUT for a radio transmitter, and transmitter circuits aren't particularly efficient.
As for propulsion, gyros are a means of orientation and perhaps navigation, not propulsion (unless, perhaps, they are off balance!). Assuming all the 1mw of power went into propulsion, at near 100% efficiency (HA!), I doubt it could fight the thermal drafts around it, assuming it got airborn (a helium baloon tied to it might help it combat gravity...). Think about trying to fight the thermal drafts around a lightbulb...putting out thousands of times the energy our fly has available to keep it on or near course.
Anyone with an aeronautical engineering background know if there is some minimum energy expenditure required to keep an object of weight X aloft? (There would be more to the calculation than just weight, obviously) Or to fight a (say) 0.05m/s headwind? (My background is Electrical Eng...I can say with authority that 1mw of power is very, very little for the electronics. I can't say with authority that 1mw is currently or theoretically sufficient or insufficient to levitate this thing) If so, this thing could possibly be proven to be impossible as presented OR possible, given sufficiently efficient parts.
The thing might actually come close to being possible with near-term technology if instead of trying to have it generate or carry its own power, it were to be powered by an external radio signal -- the mylar wings could be used as a radio antenna. Feed it with a powerful, high-frequency radio source (a microwave oven magnetron would be close to the right frequency, at least in the neighborhood), you could extract enough power from this antenna as you needed, assuming you 1) kept the wings oriented properly to the radio source (going directly towards or away from the radio source) and 2) didn't mind frying things in line with the power supply's output.
>People who say that it can't be done should not interfere with those that are doing it
Point well taken. That's a phrase I live by. I would not care if they are working with their own money, or with the money of investors who have volenteered to put it into this project. However, they are working on what, from what I can see, is very likely a thermodynamically impossible project on tax payer money. I'm not really happy about that idea. I'm more concerned about that then I am about any potential spying that this thing could ever do in my life time.
I wouldn't mind if they were working on pure research which *might* some day lead to a robofly, and after it gets airborn, wouldn't it be cool if they could control it, and then add a camera, and a transmitter... but that's not what they are saying. They said it would be hopefully flying in 2004, and the person who sold the Navy on this admitted that he didn't even know how a biological fly flies at the time he commited to the time schedule. For someone like that to say commit to a project like that just sounds too close to fraud to me.

More sinister types of orwellian mass surveillance will not, I think, be aided by this, at least for long. The big problem in spying now isn't gathering information, it's processing the incredible amounts of info that can easily be gathered. If the FBI had 24-hour video of everyone in the US, all the time, how would they make any use of it? And as these devices became cheap, their own activities would become public- and they're far more afraid of that then we are.
The one activity that would really be aided would be obsessive stalking. But I think culture would adapt to that too... there have been many successful cultures with far less privacy than ours (any primitive village), and others with far more. Humanity is quite capable of adapting to this.
