If it's good enough for the Koreans... Clicky "The robot's primary usefulness lies in its camera systems and software, enabling it to pick out genuine intruders and â according to Samsung, anyway â ignore false alarms. Human overseers can then be alerted and decide on a response. That response can be delivered by the SGR-A1 itself in some cases. Samsung says that the unit can be fitted with a range of weapons. Naturally, the option which grabs the most attention is the one where the robot packs a machine gun, rather than a wussy non-lethal system of some sort."
