Robots should be equipped with an ethical black box

Science fiction is littered with nightmare visions of robots turning against their creators, but a proposed device could help us keep track of their decision making. Intelligent machines of the future could be equipped with recorders, similar to the black box on aircraft, that would capture their ethical behaviour. This'ethical black box' would allow experts to analyse what went wrong in the event of an accident or malfunction. While it may not be enough to stop a robot from harming a human, albeit accidentally, it could prove useful in help to avoid repeat incidents. Science fiction is littered with nightmare visions of robots turning against their creators, like the Terminator (pictured).
