Humanoid
This combo picture shows a humanoid robot HRP-4C, developed by Japan’s Advanced Industrial Science and Technology (AIST) showing her skills during the Digital Contents Expo in Tokyo on October 22, 2009. A monster-slaying bad breath blow gun, a rain-simulating “funbrella” and a navigation-aid helmet that steers users by pulling their ears: welcome to Japan’s latest whacky inventions. These bizarre gadgets and more — some of them useful, most of them fun — went on display at the Digital Content Expo, a fair showcasing futuristic gaming, arts, medical and other technologies that opened on October 22.
