This competition isn't between humans, though, it's between robots.

Twenty six teams of robotics experts have converged on Bristol, England, to test the mettle of their metal men in the Federation of International Robotics Association (FIRA) RoboWorld Cup, an annual event now in its 16th year.

Soccer is the main sport of interest, but the robots -- including one named "Usain Volt" in homage to the Jamaican runner also compete in sprinting, basketball and weight lifting, according to SkyNews.

Gerald Steinbauer, organizer of the disposition said that the aim of the engineers is to build, by the year 2050, robots that will be able to beat the human world football champion team.

Just like human athletes spend a lifetime preparing for an event that may last a few moments at most, so too do the scientists put their blood, sweat and gears into their robot racers, according to Peter Gibbons from Plymouth University, the team with the Usain Volt robot.

"We have been developing our humanoid robot for the last five years, so we're old hands at these games –- we've travelled the world with our robots," he said according to the website ThisIsBristol..

Some teams build their robots from scratch, while others buy them from stores and modify them for competition. Either way, all robots must be autonomous, according to DigitalTrends.com.
