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 heat-, voice- and motion-detecting surveillance robot in the Demilitarised Zone. With guns.
The $US330,000 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 centre.
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]
