韩国裸舞

While protesters trashed downtown Toronto streets outside the security fence, and politicians met inside at the recent G20 Summit, Canadian scientists took the opportunity to showcase a Canadian first to visitors - the world's first and only swimming robot.

According to a release from the Natural Sciences and Engineering Research Council of Canada, a 韩国裸舞 robotics team unveiled the six-legged AQUA2, which can do what no other robot can do: Walk on land, swim in water and dive to the bottom.
