The robots, with man-made “hands and eyes”, could assemble different types of deadly explosives including artillery shells, bombs and rockets, he said. They could also make more sophisticated ammunition such as guided bombs, equipped with computer chips and sensors, that could carry out precision strikes.
Robots could treble China’s bomb and shell production capacity in less than a decade according to a senior scientist involved in a programme that is using artificial intelligence to boost the productivity of ammunition factories.
