2007年VOA标准英语-Young Engineers Design Robots To Score Goals, S

A robot playing a modified game of football

In a gymnasium on the campus of the Georgia Institute of Technology in Atlanta, more than 1,700 high school and university students and their faculty¹ advisers² readied their teams for a week of football -- or soccer, as Americans know it.

The athletes did not seem to mind the occasional touch of a soldering³ iron or twist of the screwdriver⁴.

That is because the players are robots, and they have come here with their human creators for RoboCup 2007, the World Cup of robotic soccer.

But these kid-size humanoids are still in the early stage of development -- movements awkward and crude.

It is hard to imagine that RoboCup's goal is to create a team of robots that can defeat the World Cup human champions by the year 2050.

But Tucker Balch, one of RoboCup's organizers, fully⁶ expects to do it. "We're already playing soccer with teams of robots with legs, that look like little people. And it's just another of many incremental⁷ steps until we reach that goal. They're all steps that we can predict and know. There's nothing magic has to happen. We just have to make steady improvement."

Balch expects to see robots helping⁸ people in their homes one day. They are already on the job at disaster sites.

In the Rescue Robot event, robots operated in a simulated collapsed⁹ building. The machines have to maneuver¹⁰ around obstacles and up stairs to find the dolls that represent human victims.

Teams from Japan, Germany and the United States have dominated RoboCup since the competition began 10 years ago, but now other countries are winning matches. Organizer Tucker Balch says that is because each country has different approaches to designing and building their robots. "What I find especially interesting is a country like Iran, where they have fantastic engineers but they don't have all of the latest computing¹¹ technology, cameras and so on. So that the technology the robots are built out of is maybe five years old, but their engineering and design is current, and they perform very, very well.

So well, in fact, that the Iranian junior soccer team -- Team Espadana -- is the defending world champion. Its robots are intensively engineered and they seem smarter than the others on the field.

Team member Amir Kherabadi says they had to beat other groups to represent their country here.

"In our league, there are about 18 teams in Iran and every year they challenge each other and then the best team comes to the RoboCup."

Teammate Najam Naderi programs the robots. He says the Iranians put in a lot of time and effort. "These [past] two or three years, we work all days and nights, eight or 10 hours a day."

All that work paid off. The Iranians robots did well at Robocup 2007. They beat soccer teams from Italy, Japan, Poland, Hungary and the United States. When the points were added up for the finals, Team Espadana wound up sharing the championship trophy¹² with the Japanese and Italian teams.

RoboCup 2008 will be held in Shanghai, just before the Summer Olympics in Beijing.
