As a Rutgers philosopher discusses robot war scenarios, one science magazine counts the ways robots are already being used in warfare, including YouTube videos of six military robots in action.

There are up to 12,000 ‘robotic units’ on the ground in Iraq, some dismantling landmines and roadside bombs, but ‘a new generation of bots are designed to be fighting machines.’ One bot can operate an M-16 rifle, a machine gun, and a rocket launcher — and 250 people have already been killed by unmanned drones in Pakistan.

He also tells the story of a berserk robot explosives gun that killed nine people in South Africa due to a ’software glitch.
