<i>'US army robots may wage a war against entire world'</i>

Echoing the scenario in the new blockbuster movie Terminator Salvation, officials at US Navy have warned that the "killer" robots being built to fight terrorists may even take over the world.
The film shows John Connor, played by Christian Bale, leading humanity in a fight with an army of Terminators controlled by the robotic Skynet.
US Navy's secretive Office of Naval Research has said that real-life robot soldiers will soon be capable of making their own battlefield decisions.
The US Army possesses many sophisticated military robots, one of which is SWORDS - Special Weapons Observation Reconnaissance Detection System -used in Afghanistan and Iraq.
SWORD can be equipped with machine guns, grenade launchers, and anti-tank rockets.
The SGR-A1 sentry robot, is another deadly droid, which has been programmed to shoot its machine gun at anyone entering the demilitarised zone between South and North Korea.
