Goodbye Rio, hello robots: Expect high-tech cool at 2020 Tokyo Olympics

Japanese Prime Minister Shinzo Abe, dressed as Super Mario, holds a red ball during the closing ceremony of the Rio 2016 Olympic Games in Rio de Janeiro. Japanese PM Shinzo Abe's show-stopping appearance at today's closing ceremony in Rio, dressed as iconic game character Super Mario, already sets the tone for what lies in store. Japan is known internationally for its technological innovations, so Tokyo 2020 organizers are aiming to launch ambitious tech projects that will boost the economy and wow crowds. Tourists staying next to the Olympic Village in Tokyo's Odaiba neighborhood can choose, for example, to hang out with robot helpers of all sizes and sorts that offer up tips on the best transport, food and entertainment options in Tokyo. And that won't be the only place they'll encounter their robotic counterparts.
