There are few borders more heavily guarded than the one dividing North and South Korea. That became even more true last month, when Seoul stationed a a heat-, voice-, and motion-detecting surveillance robot in the Demilitarized Zone. With guns.
The $330,000 unit will serve in the central section of the DMZ, and is considered a test to determine the practicality of broader deployment. It's outfitted with both a gun and a 40mm automatic grenade launcher, which are controlled from a remote command center.
While this is a sentry robot—though one that's armed and dangerous—Seoul's robotic efforts include Terminator-like combat bots that would actually join human soldiers in the battlefield. [Telegraph UK]
