Robot Guilt?

The robot courses across the battlefield, swiveling on sleek steel legs, turning its bullet-shaped head toward its prey. Its eyes flash red, then blue: signal received. Before the ensuing sound boom and the inevitable end of hundreds of lives, it pauses a moment to reflect. Death is never easy, even with a heart of circuits.

Battlestar GalacticaOkay, so maybe not quite like that, but you get the drift. To a demographic familiar with Cylons and Replicants, the concept of robot warfare might not seem so far fetched. But according to the New York Times, great strides are being made to program ethics, and even guilt, into robots designed for combat.

Believe it or not, there are already over 18,000 unmanned systems deployed in Iraq now, so the issue of robotic warfare is moot at this point. It’s here, whether or not we are comfortable with it. But Ronald Arkin of Georgia tech is out to change the way robotic warfare is conducted and to improve it: after a three year programming project working with the U.S. Army he believes that “in limited situations, like countersniper operations or storming buildings, the software will actually allow robots to outperform humans from an ethical perspective.”

Essentially he’s working to create a robot super brain, far out performing the average soldier in difficult situations. Arkin explains, “I believe these systems will have more information available to them than any human soldier could possibly process and manage at a given point in time and thus be able to make better informed decisions.”

And beyond logic and reason, beyond even ethics, Arkin wants to instill guilt in the programming to mimic “remorse, compassion, and shame”. According to the article, guilt allows to change outcomes and generate constructive change.

While fighting, his robots assess battlefield damage and then use algorithms to calculate the appropriate level of guilt. If the damage includes noncombatant casualties or harm to civilian property, for instance, their guilt level increases. As the level grows, the robots may choose weapons with less risk of collateral damage or may refuse to fight altogether.

Of course, this brings about a slew of questions. Can remorse really be programmed? Or, as I thought when I first read this piece, isn’t the point of robot warfare to make them inhuman? Or is it just a matter of being able to get into difficult places and minimize “true” loss of life? These are the questions that sci-fi has been exploring for years. It’s quite something else altogether to see it manifested.

All this has happened before, and all of it will happen again. Two tickets to Kobol, anyone?



The Science Behind Ferrofluid

Ferrofluid is an assemblage of magnetic particles engineered at the nanoscale, 100 times smaller than the wavelength of visible light. Although too small to be imaged with microscopes, nano-products harness surprising properties from nanoscale physics for use in the macroscale world.

4G mobile broadband becomes a reality

Samsung 4g Dongle

A Swedish firm has become the first to offer 4G mobile broadband services for consumers. But the service has been described as a “killer user experience” rather than a “killer app”.

The service from TeliaSonera AB will debut in the next few months, initially in Stockholm, Sweden and Oslo, Norway, extending it across the two countries throughout the year. At launch there won’t be any compatible handsets: the service will instead be available for laptops via a dedicated USB dongle produced by Samsung.

In theory, 4G broadband could reach up to 100 megabits per second. That’s 12.5 MBps, which would be classed as a decent fixed-line broadband speed in most places in the world.

The main note of caution for would-be 4G users is that it there aren’t any imminent changes in what you can do with the technology compared with 3G, beyond simple increasing speed. With the 2G to 3G leap, several features became credible options, most notably streaming video and even video messaging. The change from 3G to 4G theoretically allows better resolution video to be streamed, but that’s going to make little noticeable difference on existing handset screens. Of course, on laptops it’s a different story and means watching live TV on the move without squinting could become viable.

The features most likely to benefit from 4G may include videoconferencing for multiple participants and better quality online gaming. However, the market is probably at the chicken-and-egg stage with developers hesitant to put too much effort into applications until there is a sizeable enough user base, and users unwilling to upgrade until there are more benefits to doing so.

Another important issue in the 4G market’s development is how networks manage demand. Getting data ten times as quickly isn’t much more attractive if customers are still subject to tight constraints on monthly data use. But without such limits, some users will inevitably push the network’s capacity to its limit.

Early adoption of the technology may also be limited by the fact that the 4G dongle doesn’t cover 3G reception, meaning that anyone who may leave the 4G coverage area will need two dongles. A dual-format dongle won’t be available until the middle of 2010.

To hook new customers, the firm is offering free modems for the first six months, along with a trial price of just 4 kroner (approximately 56 US cents) a month. In July, the price will then rise to its standard cost of 500 kroner ($70) a month. While that’s theoretically a great way of letting people become dependent on the service and paying up later rather than returning to the slower speeds, there is the possibility that the 4G network will become overloaded if too many people sign up for the offer.

The bed that made the Kessel Run in less than twelve parsecs

From Kayla Kromer, creator of the famed Hamburger Bed, comes a must-have bed for Star Wars fans: The Millennium Falcon. Like the “real” Falcon, the bed features hidden compartments (for smuggling, though I didn’t think I’d have to smuggle myself in them) working headlights, and a radar dish pillow (try not to knock it off the bed when fighting the second Death Star.) The bed can even accommodate multiple action figures inside its cockpit.

Game sales figures tell many stories

Market researchers NPD have released their estimates for video game sales figures for November. For what’s theoretically a simple enough figure – $2.7 billion – there are plenty of lessons to be learned:

Everything is a matter of perspective. If you’re feeling the blues, it’s a depressing 7.6% slump on last year’s November figures, suggesting “Christmas stockings are going to be a bit on the empty side this year.” But if you’re full of seasonal joy, it’s the second best November figure on record, beaten only by 2008 being an “incredible year”.

It may or may not have been the result of airport terrorism controversy, but Modern Warfare 2 was a true blowaway hit. With more than 6 million sales, it’s destroyed all records for a newly-released game. And without it, overall sales would have been down by a much more significant margin.

Online gaming is becoming more important in driving sales. While there are only about 25% more Xbox 360 users than PS3 users, Modern Warfare sold more than twice as many copies on the Xbox. A spokesman for Microsoft made the credible, if somewhat biased point that this may very well be down to the idea of playing the game online being more appealing to Xbox Live users.

The price cut that came with the PS3 Slim certainly seems to have done the trick, with sales almost doubled from last year. It’s still in third place, but at 710,400 sales for the month, it’s closing in on the Xbox at 819,000 (which is barely changed from last year). The Wii remains out in front at 1.26 million, though that’s down from over 2 million at the same point last year, despite a recent price cut.

Subjective game quality is not necessarily reflected in sales. A report by Metacritic for 2009 as a whole found that while the Xbox had the highest quantity of games rated highly, the PS3 had the highest average rating as well as making up five of the 10 best rated individual games. And while the Wii has far more titles released, a clear majority of them were poorly rated. The site takes its ratings by averaging the scores awarded by a range of game review sites.
