The Japan Robo-One competition is coming up this March at the National Museum of Emerging Science and Innovation (Miraikan). The Robo-One events focus on bi-ped walking robots, though they often include lots of related technology and unique designs. As you might imagine, many of the robots resemble Gundam or Transformers. While the designs can get pretty creative, the competition challenges are very relevant and drawn from real life situations - things like walking up a set of stairs, or opening a door.
The Junior events are scheduled for March 13th, followed by a week long exhibition at the museum. The following weekend, March 19th and 20th the final competition will take place. The top prize is listed at 1 million yen (roughly USD$10,000) with other prizes to be announced before the competition.
If it's at all possible, I plan on attending the competition for at least one of the days. If anyone else plans on attending, feel free to contact me so we can link up.
Access to the Miraikan venue is easy from anywhere in the general Tokyo/Chiba/Kanagawa area-
