An anonymous reader quotes a report from Metro: While machines from the likes of RoboCop and Chappie might just be the reserve of films for now, this new type of robot is already fighting crime. This particular example can be found guarding a shopping center in California but there are other machines in operation all over the state. Equipped with self-navigation, infra-red cameras and microphones that can detect breaking glass, the robots, designed by Knightscope, are intended to support security services. Stacy Dean Stephens, who came up with the idea, told The Guardian the problem that needed solving was one of intelligence. "And the only way to gain accurate intelligence is through eyes and ears," he said. "So, we started looking at different ways to deploy eyes and ears into situations like that." The robot costs about $7 an hour to rent and was inspired by the Sandy Hook school shooting after which it was claimed 12 lives could have been saved if officers arrived a minute earlier.
