Philip K. Dick 
Second Variety 

In Second Variety, UN forces have retreated to a moon base in the aftermath of early Soviet victories in a nuclear conflict. In response, the UN forces developed special robots, called Claws, which feature spinning blades and rudimentary artificial intelligence. Six years later, the Soviet leadership asks for negotiations to end the war. A UN officer travels back to earth to discover that not only have the Claws learned to replicate themselves, they have also created a much deadlier cyborg that threatens humanity itself. The inspiration for the movie Screamers.
