Sure, Robots Might Kill Us. They Also Could Rescue Us From Land Mines, Natural Disasters and Collapsing Buildings

Aerial drones can be used to locate disaster survivors – or to pepper-spray protestors. Their earthbound robotic cousins can help rescue victims of events like a building’s collapse – or make fresh victims on the battlefield.
Robots’ duality – their ability to help or harm people – isn’t lost on their evangelists. Debates are building over the anticipated arrival of lethal autonomous robots, for example, and unmanned armed vehicles.
“If robots can squeeze the handle of a steering wheel and manipulate the air conditioning controls on your Ford Escort, they can also squeeze the trigger of an AK-47 and a grenade launcher,” points out Illah Nourbakhsh, robotics professor at Carnegie Mellon University.
