DARwin-OP, CHARLI-2 humanoids make history at RoboCup 2011, 'U-S-A!' chants ensue (video)
While most American sports fans were busy celebrating a World Cup victory over Brazil this weekend, an indubitably more compelling soccer tournament was drawing to a close in Istanbul -- site of RoboCup 2011. Virginia Tech's Team DARwin made history at this year's event, becoming the first US squad to bring home top honors in both the Kid Size and Adult Size competitions. The petite DARwin-OP humanoid danced circles around the lightweight class, while the five-foot CHARLI-2 demoralized Robo Erectus in the big boys' final with a last-minute penalty kick. In its international debut, the CHARLI-2 (pictured, in a moment of Zen, on the right) also earned the vaunted Louis Vuitton Humanoid Cup, ending a nine-year period dominated by teams from Germany and Japan. These programmed Peles may not the most graceful of strikers, but RoboCup organizers remain convinced that autonomous bots will be able to compete with human athletes by 2050 -- which might just give us enough time to develop a taste for soccer. Dribble past the break to see Team DARwin in action, along with an extra clip from the BBC.
Virginia Tech researchers reveal full-sized CHARLI-L humanoid robot (update: video!)
Dr. Dennis Hong was kind enough to give us a glimpse the CHARLI robot on The Engadget Show this weekend -- or its leg, anyway -- but he and his students have just now finally revealed the full-sized bot that's been described as a "robot teenager." As we'd heard, CHARLI is actually a series of robots that initially consists of the 5-foot tall CHARLI-L (or lightweight, pictured above), and the forthcoming CHARLI-H (or heavy), both of which are completely autonomous, with a full range of movements and gestures thanks to a series of pulleys, springs, carbon fiber rods, and actuators (not to mention some slightly more mysterious AI). What's more, while CHARLI-L is currently restricted to walking on flat surfaces, CHARLI-H promises to be able to walk on the uneven ground around the Virginia Tech campus, and eventually even be able to "run, jump, kick, open doors, pick up objects, and do just about anything a real person can do." Unfortunately, there doesn't seem to be any video of CHARLI-L in action just yet, and it is still somewhat of a work in progress -- the researchers say it will be able to speak soon, and they're also busily working to improve its soccer skills in time for this year's RoboCup. [Thanks, Kyle] Update: Video is now after the break!
Robotic hand controlled by compressed air grasps the concept of delicacy
The Robotics and Mechanisms Laboratory (AKA the RoMeLa Project) at the College of Engineering at Virginia Tech has designed and built a prototype robotic hand that is controlled and operated by compressed air. Called RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments), the robot can hold heavier, solid objects, as well as light or delicate ones such as a light bulb or an egg. The hand is powered by a compressor air tank at 60 psi and an accordion style tube actuator, with microcontroller commands operating and coordinating the movements of its fingers. It uses no other motors, and the strength of the grasp is controlled by a change in air pressure, making the hand quite dextrous. RAPHaEL -- which is part of a larger RoMeLa robot project named CHARLI -- has already won several awards, including grabbing first prize at the 2008-2009 Compressed Air and Gas Institute Innovation Award Contest. RoMeLa researchers envision CHARLI one day roaming the VT campus making friends with students and visitors. We look forward to that day, but until then, check out RAPHaEL holding some stuff after the break.
