Winner robot’s design is very sleek. It’s COG balanced with neodmium magnets. Robot Sumo matches can be quick and deadly, or they can be long and packed full of drama. This match took place during the February 2006 All Japan Robot Sumo competition in Yokohama, Japan. It starts off a little slow, but finishes with a big bang of excitement.
The All Japan Robot Sumo competitions start in the early Fall on a regional basis then built up to the finals held in mid-December in Tokyo. This set of videos was taken at the Kanto Regional Finals. For more information visit ROBOTS DREAMS at www.robots-dreams.com.
