If you happen to be in the Yokohama area on Sunday afternoon (February 19th), drop by the Pacifico Yokohama convention center and catch some sumo robot action. This particular event, the 17th Japan Nationals for 10 kg (22 lbs) sumo robots, is sure to offer lots of heavy competition and excitement. The doors open at noon, and the contests are scheduled to finish up around 3:00 pm ? though they sometimes finish ahead of schedule. If you happen to notice a tall foreigner, with an obvious obsession with things robotic, taking photos please come up and say hello.
