The RoboCup is the World Cup for robots.
In China this weekend, tiny robots of all shapes and sizes took to the field in the 19th annual competition, which brings together thousands of contestants from more than 47 different countries and regions. Robots will compete until July 23, when they will crown a RoboCup champion.
The goal? To create a robotic soccer team that will be able to beat the winner of the World Cup by 2050.
