Every year, people from all over the world compete see who can build the fastest mouse. Mouse robot that is. These Micromouse competitions have miniature wheeled robots searching through mazes, finding the best path to their goal, and then racing to victory at speeds that may be hard to follow. The 31st Annual All Japan Micromouse Competition is set for November 20th, and already there’s a fore-runner that is catching a lot of attention. In the recent regional finals in Chubu, a builder named Kato displayed one of the fastest robots we’ve ever seen, especially in this size. Called Egg-Torte, the half-sized micromouse whips through a complex maze in the video below. Did it win the regional? Oh yes. And it might be the favorite to take the crown at the nationals in a few weeks. Bots like this one are a testament to the innovations generated by robotic competitions all over the world.
