Electric Skin that Rivals the Real Thing

See original article at Technology Review.

In Artificial Intelligence, an agent is defined as an entity that perceives and acts in an environment. Here's an example of a cool technology for perceptual input.
"The tactile sensitivity of human skin is hard to re-create, especially over large, flexible surfaces. But two California research groups have made pressure-sensing devices that significantly advance the state of the art."

One, made by researchers at Stanford University, is based on organic electronics and is 1,000 times more sensitive than human skin. The second, made by researchers at the University of California, Berkeley, uses integrated arrays of nanowire transistors and requires very little power. Both devices are flexible and can be printed over large areas; they are described this week in separate papers in the journal Nature Materials.

The Brain Speaks

See original article at The University of Utah.

A logical next step in human augmentation / technological integration.
"Sept. 7, 2010 -- In an early step toward letting severely paralyzed people speak with their thoughts, University of Utah researchers translated brain signals into words using two grids of 16 microelectrodes implanted beneath the skull but atop the brain."

Screensaver discovers new star

One of the first significant applications of distributed computing I heard about (and actually participated in) was SETI@home, a project that uses the computers of volunteers to analyze radio telescope data. Another is the search for Mersenne Primes -- in 2008 the Great Internet Mersenne Prime Search (GIMPS) found the then-largest known Mersenne Prime; a number that would stretch 30 miles if printed in 12-point type.

Here's another success of distributed computing: the discovery of a new star:
"WASHINGTON -- Astronomers announced Thursday the discovery of a new star, found with help from a most unusual source -- a screen saver.

Chris and Helen Colvin, owners of the personal computer running the screen saver are participants in a project called Einstein@home, an experiment in distributed computing that uses the donated idle time from hundreds of thousands of home computers across the globe in lieu of more expensive supercomputers."

With robot car, no driver needed

An interview with Alberto Broggi, leader of an autonomous driving project.
"We are making a three-month journey, travelling 13,000 kilometres from Parma, Italy, to Shanghai, China, using autonomous vehicles - a world first. We've just left Moscow and are heading to Siberia."

Translating Thought into Speech

See original story at latimes.com
"In a first step toward helping severely paralyzed people communicate more easily, Utah researchers have shown that it is possible to translate recorded brain waves into words, using a grid of electrodes placed directly on the brain.

Although they have only done it with one person and individual words can only be identified with accuracy in tests 50% of the time, the study reported Tuesday provides a ray of hope for people who can now communicate only by blinking, or wiggling a fingertip."

Your trash can may be watching you...

Students in COSC418 -- I saw this article and couldn't resist. Not exactly the same as the FoamRecycleBot we described in class on Monday, but a step in that direction. Challenge question: in which aspect of "PEAS" does the agent described in the article differ from the one we described in class?
"It would be a stretch to say that Big Brother will hang out in Clevelanders' trash cans, but the city plans to sort through curbside trash to make sure residents are recycling -- and fine them $100 if they don't."

Swarming spacecraft to self-destruct for greater good

See original at New Scientist

Students in COSC 180 -- this is a step toward the kind of space exploration we mentioned in class last Thursday -- using many many small devices rather than one large one. The probes described in this article aren't yet "smart dust," but they are a step in that direction.

Also interesting is the behavior described in the article and referred to in the title: self-destruction of individual probes "for the greater good of the collective." Begins to sound a bit like altruistic behavior, no?
"The agency foresees a day when space missions are undertaken not by one large spacecraft but by swarming formations of much smaller, cheaper ones. Such craft could collectively provide a 'floating optics' system for a space telescope comprising separate craft flying in formation, for instance."
