From the We Built It Because We Can file, otherwise known as Japanese robotics, comes the latest blow to the future of humanity: an erosion of our supremacy at games of chance.

Billed as a showpiece for what they describe as human-machine co-operation systems, researchers at the University of Tokyo’s Ishikawa Oku Laboratory have come up with a robot arm that will mercilessly thrash you in a game of “janken,” or rock-paper-scissors.

According to its creators, the janken bot uses high-speed vision to quickly identify the position and shape of a human hand, allowing it to successfully predict an opponent’s move  — a display of technology they say will allow machines and humans to communicate and complete tasks as a team without delay.

The janken bot is the latest in a string of greatest hits from Japanese minds, hits that also include a responsive set of buttocks, powder-based kits for homemade take-out, robot guide dogs and, of course, an infamous Whopper lightly garnished with 1,050 slices of bacon.
