The American military is planning to build robot soldiers that will not be able to commit war crimes like their human comrades in arms.
The US Army and Navy have both hired experts in the ethics of building machines to prevent the creation of an amoral Terminator-style killing machine that murders indiscriminately.
By 2010 the US will have invested $4 billion in a research programme into “autonomous systems”, the military jargon for robots, on the basis that they would not succumb to fear or the desire for vengeance that afflicts frontline soldiers.
