If I can get a video camera from somewhere, I can post "Ferret VS. Robosapien" to YouTube. However, I will try to avoid constant petblogging, and be mindful that not everyone is as enamored of a pet as their person. :)

I'll post a thorough report of my weekend tonight. In the meantime here's a quick post.

Has no one else noticed that the breakthroughs which led to the motion-sensing technologies in the Nintendo Wii can be applied to robotics? Robots have almost never had the slightest clue where their bodies were positioned in space, except through dead reckoning from their memory of commands they sent to their moving parts, from a presupposed starting position. If an exterior object moved them by bumping them, they usually could not tell at all-- or at most, barely. My Robosapien has no idea when he's not standing upright.

Now that ultra-sensitive mechanical accelerometers have been wildly miniaturized, and more importantly the infrastructure is in place to mass-produce them at radical cost reduction for the new generation of game controllers, some hardware hacker is probably already planning to repurpose them for the vestibular (inner ear) and proprioception (body pose) senses of robots.

Goatchurch on the MundaneSF blog posted about his skepticism of molecular nanotechnology. He asked why we think a self-propelled miniature machine can exist, when we still don't have a robot that can vacuum the living room. (Given the existence of Roomba, that's another claim which, in itself, I would highly debate.) Here is the response I put there.

The failure of modern robotics is a software problem. But whether or not that is solvable is not relevant to nanotechnology, which rarely considers molecular robots. There is vast potential in nanotech products and materials that are not only dumb, but downright inert and permanently motionless. The potential of nanosystems which, while not motionless, are nevertheless dumb and sessile, is even more vast.


Look at this computer animation concept. Note that nothing in the assembly line depicted here involves individual nanorobots with independent self-propulsion, self-guidance or decision-making. Independence and intelligence are not required of molecular machinery. Don't confuse the "Universal Assembler/Disassembler" myth with the nanosystems that are actually being proposed.

MIT's Technology Review has a video documentary series titled "The Impact of Emerging Technologies" which is exclusively online. It's really interesting! It covers stem cells; robotic prosthetics with a mind/machine interface; artificial polymer muscle; computer interpretation of body language; nano-scale valves; and more.

The video about using lab yeast instead of lab mice for a 50,000-fold decrease in cost and slowness of new drugs showed them using robot laboratory systems. It reminded me of an article on Edge.org by Kevin Kelly, editor of WIRED Magazine, about using robots, Google, Wikis, "Zillionics" and more, to practice science in the future.

Wow.

The researchers who constructed a robot with "mirror image cognition" are evidently looking at their project from the point of view of asking whether the robot is doing what it is we do. Or at least, what very simple animals do, such as insects. "Consciousness." "Self-awareness." I think the attempt to make that comparison only leads to dissapointment, because there is a tendency to define intelligence as whatever it is artificial intelligence researchers haven't accomplished yet. Instead, look at it as doing something new and useful that robots haven't done before. According to Discovery Channel News:

"A new robot can recognize the difference between a mirror image of itself and another robot that looks just like it.
...
Humans learn behavior during cognition and conversely learn to think while behaving, said Takeno.

To mimic this dynamic, a robot needs a common area in its neural network that is able to process information on both cognition and behavior.
...
Imitation, said Takeno, is an act that requires both seeing a behavior in another and instantly transferring it to oneself and is the best evidence of consciousness."

This robot is controlled by a trackball mounted to it. More to the point, it's controlled by a giant hissing cockroach on the trackball which shies away from lights that are shined in its face when the robot approaches an obstacle. Cool!

Cory Doctorow asked to present a panel at Penguicon about "The Hidden Totalitarian Assumptions of I, Robot." I've been curious ever since he told me this.

Now it turns out he's published a new story about it on the Infinite Matrix website titled I, Robot. After the story he writes, "Last spring, in the wake of Ray Bradbury pitching a tantrum over Michael Moore appropriating the title of 'Fahrenheit 451' to make Fahrenheit 9/11, I conceived of a plan to write a series of stories with the same titles as famous sf shorts, which would pick apart the toalitarian assumptions underpinning some of sf's classic narratives."

It's an excellent story but I still don't get the point. The money quote is probably this from a Eurasian missionary/secret agent to a Canadian cop: "You live in a country where it is illegal to express certain mathematics in software, where state apparatchiks regulate all innovation, where inconvenient science is criminalized, where whole avenues of experimentation and research are shut down in the service of a half-baked superstition about the moral qualities of your three laws, and you call my home corrupt?" But as far as I can tell, some characters decided to be totalitarian dictators, and other characters in their society allowed them to be, for reasons which I can only dimly connect to the three laws or to Asimov's book, probably because it's been years since I read it. (The movie, which was a script called Hard Wired until they slapped the I, Robot name on it for no good reason, doesn't count.) Why don't the Eurasian robots, who are not "3 Laws Safe," run amok and take over the world? The story does not say. In asking that question, am I making one of the totalitarian assumptions of I, Robot?

A few months ago I bought it the e-book from Fictionwise.com, but from this LJ entry you might recall how Digital Rights Management screwed me out of my property. I don't know if I'd call that totalitarian though.

This address by Christian cognitive scientist Edmund Furse is a totally straight-faced explanation of how robots, in his opinion, will be able to do things like sin, or communicate with God. An excerpt:

..."give us this day our daily bread" might have to be replaced by "give us our regular electric feed".

...It seems to me that Christ died for all persons, male, female, human and robot. A second argument might be that a robot is unlikely to be an icon of Christ at the altar, but I suppose that priestly robots could grow long hair and a beard if desired.


A noble sentiment indeed. Followed later by this:

Could a robot steadfastly set its face against the will of God. Could a robot continuously know what is the right thing to do, and yet choose to go against it. Could a robot ultimately choose to reject God and all goodness, and desire to be cut off from God and his grace for all eternity? Surely a robot being so knowledgeable would choose a path of goodness. But we have to allow for the possibility of free choice, and in allowing the robot this possibility, we also have to allow for it to ultimately to go to Hell.Read more... )

I, Robot

Scientists today detected a slight wobble in the earth's orbit. It was determined to be caused by Isaac Asimov spinning in his grave. I was seriously annoyed when I saw the trailer to I, Robot and realized it was yet another modernity-phobic action movie. The book I, Robot was a thoughtfully philosophical collection of detective stories about the communion of mindkind. Just like with Paul Verhoeven's film of Heinlein's Starship Troopers, the director of the film probably never read the book.
