Teams from all over the world competed in the International Robot Sumo Tournament 2015 on December 13, 2015, in Tokyo, Japan. The event was held at the famous Ryogoku Sumo Hall. 14 winners of local robot sumo tournaments from around the globe joined the winners of the All Japan Robot-Sumo National Tournament and the All Japan Robot-Sumo High-School Tournament to see which robot would be the strongest. There were two divisions, one for radio controlled "sumo robots" and the other for autonomous wrestlers. In the radio controlled division the Japanese team defeated Mexico in the final for the second year in a row. (Video by Rodrigo Reyes Marin/NipponNews.net)
