Here's a robot video that I found interesting:
Thousands of students powered up for the ultimate robot showdown at the 2013 VEX Robotics Competition World Championship, presented by the Robotics Education and Competition Foundation.
More than 10,000 students from 20 countries will competed for the winning title at the annual VEX Robotics Competition World Championship. More than just an exercise in programming and driving robots, this competition helps kids turn robotics into an engaging hands-on sport that is riveting to watch. Through robotics, these students are being shaped into tomorrow's visionaries who will create the next big improvements in Science, Technology, Engineering and Math (STEM).
