Hmm, you started something going in my mind with this! Have had to break out the Bluetooth keyboard for more accurate typing than on the onscreen job.
Going back to ''The Three Laws'': IIRC there was only one company, US Robotics, capable of producing the ''positronic brain'' required for the robots - the thing that made them so special. I do not remember, in any of the stories, that anyone attempted to reverse engineer the brains to be able to pirate the design. I also seem to remember that there was no international conflict.
So, the perfect world where no-one is going to make ''wild'' robots or robot soldiers? What would the likes of N. Korea do with such technology? It might already be possible to make a tracked robot that would recognise a human figure in any position - standing, kneeling, running etc - and aim a weapon at that ''target''. Current sensor systems and servos, linked to a dedicated mini-super-computer, would make it very quick and accurate. Maybe, because of expense, the supercomputer could even be remote, controlling a ''cluster'', a ''distributed'' robot system. No decision making, shoot on sight.
