Here's a robot video that I found interesting:
Robot Japan features several different types of events, but the most popular by far has always been the ROBO-ONE style humanoid battles. Many of the competitors are actually ROBO-ONE champions.
This particular match pits Garoo against Chrome Kid for the Robot Japan Championship. At the end of the standard 3 minute match the score was tied, so they went into Sudden Death overtime with the win going to the robot that scores the first knock-down.
