Meet the Pibot, South Korea's answer to the unmanned aerial drone. Shim Hyung-Chul and his colleagues at the Advanced Institute of Science and Technology in Daejeon, South Korea, aren't trying to replace the drone, Shim tells Reuters, but he argues that the Pibot has one big advantage: It "can immediately automate any kind of aircraft." That's handy for instances when flights are too dangerous for human pilots, such as after a nuclear disaster.The Pibot has proven adept at flying a computer flight simulator and even a miniature airplane.
