South Korea has unveiled the latest piece of evidence that the future is finally upon us: it's supplementing its soldiers manning the border with North Korea with "gun-toting sentries" that can detect baddies and kill them. Or as Lee Jae-Hoon, deputy minister of commerce, industry and energy told the Agence France Press: "The Intelligent Surveillance and Guard Robot has surveillance, tracking, firing, and voice recognition systems built into a single unit." The South Korean government is expected to buy 1,000 of these robots at the cost of $200,000 apiece and will deploy them along its northern border, coastal regions and military airfileds. However, it's unclear what would happen if Kim Jong Il were to send in a legion of pilfered remote-controlled domestic robots as a countermeasure -- that is, if these robotic sentries would be willing to fire on their own kind.Update: Eagle-eyed reader (and likely Korean speaker) Jihan J. happened upon a Korean site with pics and an actual video of this bot in action. Go on and check it out -- that is, if you like watching robots shoot automatic weapons wildly in every direction.
