A hundred humanoid communication robots called Robi perform a synchronized dance during a promotional event called 100 Robi, for the Weekly Robi Magazine, in Tokyo January 20, 2015. The 34cm-tall (13.4-inch) robot, designed by Tomotaka Takahashi, chief executive officer of Robo Garage Co and project associate professor of Research Centre for Advanced Science and Technology at the University of Tokyo, is able to speak, walk and dance. The weekly magazine comes with parts of the robot, which allows buyers to have a fully assembled Robi after 70 issues. REUTERS/Yuya Shino (JAPAN - Tags: SOCIETY BUSINESS TPX IMAGES OF THE DAY)
