Pakistani robotics masters compete for soccer honors

A Pakistani team is vying for the RoboCup for the first time, and the robots’ odds are better than their human counterparts’

The little striker wearing a crescent moon and star jersey lines up his penalty and kicks right, netting his goal as the goalkeeper dives the wrong way and hits the ground yelping in pain.

Both players are teammates practicing to represent Pakistan in a major world soccer tournament. However, unlike their low-ranked flesh-and-blood counterparts, these are advanced robots whose programmers are set to compete against students from the world’s top universities as they look to showcase what their country can do in the world of artificial intelligence.

Students at Pakistan’s National University of Science and Technology (NUST) this year sent a team for the first time to the annual RoboCup, an event featuring 32 universities held in Leipzig, Germany, from Monday to tomorrow.

The six machines are Nao humanoid robots purchased from France’s Aldebaran Robotics at a cost of roughly US$17,000.

It is in fact the third year that NUST, Pakistan’s premier engineering institute, has qualified for the prestigious cup. However, a lack of travel funds has meant their dream of representing their country on the world stage had to be placed on hold — until now.

“Our dream came true this year when the university managed to allocate 1.5 million rupees [US$22,325] for the team’s travel to Germany,” Yasar Ayaz, head of the university’s Department of Robotics and Artificial Intelligence, told reporters.

The amount was enough only for three students instead of all 10 involved in the project to travel to Germany and participate in the event, but the university was hoping to close the gap with funding from sponsors.

“We are not disheartened... Something is better than nothing,” Ayaz said.

The first robot soccer league was started in 1993 by a group of Japanese researchers and named the Robot J-League, after the Japanese professional league.

Following a surge of outside interest, the initiative was extended into an international project and the Robot World Cup Initiative, or RoboCup, was conceived.

The first edition was held in Osaka in 1996. Its stated aims were: “By the middle of the 21st century, a team of fully autonomous humanoid robot soccer players shall win a soccer game, complying with the official rules of FIFA, against the winner of the most recent World Cup.”

However, for the time being that goal appears a long way off.

Students tap away at their laptops in their university lab, programming their code. Zain Murtaza, who leads the 10-member team, sets up the cute robots on their 2.74m by 1.83m pitch, and the action begins.

Each robot has two cameras on their faces guiding their movements.

“The cameras take pictures and feed them to the computers installed inside, which help them decide about their movements and recognize movements of the other players,” Ayaz said.

They walk around the field with short staccato movements, pulling their legs back like a golfer lifts his club before unleashing an ungainly kick that sends the plastic orange ball rolling along the floor.

Mishaps and tumbles are frequent, and the process makes for awkward viewing. Humans are allowed to make minor interventions, but the robots’ movements are entirely their own, with results hinging on how cleverly the machines are programmed to carry out their roles.

The work is a labor of love for the Pakistan team.
