This is not science fiction. It is a real and powerful threat to humanity". These are the first words of a Human Rights Watch Petition to Presdient Obama to keep robots from the battlefield. The argument is that robots possess neither common sense, "real" reason, any sense of mercy nor — most important — the option to not obey illegal commands. What with the fast-spreading use of drones et al. , we are allegedly a long way off from Asimov's famous Three Laws of Robotics being implanted in autonomous fighting machines, or into any ( semi- ) autonomous robot. A "Stop the Killer Robots" campaign will also be launched in April at the British House of Commons and includes many of the groups that successfully campaigned to have international action taken against cluster bombs and landmines. They hope to get a similar global treaty against autonomous weapons. The Guardian has more about this, including quotes from well-known robotics researcher Noel Sharkey from Sheffield University."
