The Robocup started in 1997 with 37 teams in Japan and now caters to over 500 teams from around the globe. Robots are separated into size categories including small, teen, kid, and adult. Classifying in the adult category this year was Virginia Tech's CHARLI (short for Cognitive Humanoid Autonomous Robot with Learning Intelligence). CHARLI Weighs in at 27 pounds, and is powered by 29 motors, and assembled with only 276 parts. CHARLI won the RoboCup 2011 adult class for the US. Watching the tournament, his gait was steady and stride twice as fast as competitors. Also taking home a US win was team Darwin-OP kid class robots.
