Japan loves robots, and Japan loves sumo. So what would be more obvious than robot sumo? The so-called FSI Japan Robot-Sumo Tournament recently took place in the Ryogoku hall in Tokyo (where the real sumo wrestlers have their tournaments, too, by the way) – and we have two videos from the finals.

There were two kinds of robots battling it out, autonomous and radio-controlled models. In total, 102 robots were registered for the tournament (which took place earlier this week) this time.

Here is the final bout in the autonomous robot class:
