名师大咖面对面，有问有大收获多。Football fever will continue in Brazil next month when robotic teams from around the world will gather there seeking to win their own championship. In preparation, U.S. technology students at the University of Pennsylvania are "coaching" a team of robots with a goal of winning a fourth consecutive victory at the international event known as the RoboCup.
Watching robots play football is similar to watching small kids play the game. The kicks are awkward, there's a lot of falling down, and grown-ups are there to coach and cheer. Jian Qiao Li, a robotics student at the University of Pennsylvania, is one of the team creators.
"Our goal is in two parts. Part one is to detect the goal and the ball and localize itself in the field. The second part is just the locomotive part, like control the walking and the gait and the kick," says Jian.
