Robots, the next generation of soccer players
If you think a robot will steal your job, you are not alone. Soccer players should be worried too. The next Messi probably won’t be of flesh and blood but plastic and metal.
The concept emerged during the conference “Workshop on grand challenges in artificial intelligence,” held in Tokyo in 1992, and independently, in 1993, when Professor Alan Mackworth from the University of Bristol in Canada described an experiment with small soccer players in a scientific article.
Over 40 teams already participated in the first RoboCup tournament in 1997, and the competition is held every year. The RoboCup Federation wants to play and win a game against a real-world cup humans’ team by 2050.
The idea behind artificially intelligent players is to investigate how robots perceive motion and communicate with each other. Physical abilities like walking, running, and kicking the ball while maintaining balance are crucial to improving robots for other tasks like rescue, home, industry, and education.
Designing robots for sports requires much more than experts in state-of-the-art technology. Humans and machines do not share the same skills. Engineers need to impose limitations on soccer robots to imitate soccer players as much as possible and ensure following the game’s rules.
RoboCup Soccer Federation, the “FIFA” of robots, which supports five leagues, imposes restrictions on players’ design and rules of the game. Each has its own robot design and game rules to give room for different scientific goals. The number of players, their size, the ball type, and the field dimensions are different for each league.
In the humanoid league the players are humanlike robots with human-like senses. However, they are rather slow. Many of the skills needed to fully recreate actual soccer player movements are still in the early stages of research.
The game becomes exciting for middle and small size leagues. The models are much simpler; they are just boxes with a cyclopean eye. Their design focuses on team behavior: recognizing an opponent, cooperating with team members, receiving and giving a standard FIFA size ball.
Today, soccer robots are entirely autonomous. They wireless “talk” to each other, make decisions regarding strategy in real-time, replace an “injured” player, and shoot goals. The only person in a RoboCup game is the referee. The team coaches are engineers in charge of training the RoboCups’ artificial intelligence for fair play: the robots don’t smash against each other or pull their shirts.
The next RoboCup competition will soon be played, virtually, with rules that will allow teams to participate without establishing physical contact.

Gabarito

B

Comentário do professor

Alternativa correta: A alternativa B está correta porque o texto menciona que o conceito dos jogadores de futebol robóticos surgiu durante a conferência “Workshop on grand challenges in artificial intelligence,” realizada em Tóquio em 1992, e também em 1993, quando o Professor Alan Mackworth descreveu um experimento. Portanto, a década de 1990 é a correta, já que tanto 1992 quanto 1993 pertencem a essa época.


Alternativas incorretas:

A: Esta alternativa está incorreta porque 1997 refere-se ao ano da primeira competição RoboCup, e não à origem do conceito de jogadores robóticos, que ocorreu em 1992 e 1993.


C: Esta alternativa está incorreta porque o texto menciona claramente que o conceito surgiu na década de 1990, e não antes dessa década.


D: Esta alternativa está incorreta, pois a afirmação de que o conceito surgiu no início do século 20 não é suportada pelo texto, que especifica os anos de 1992 e 1993 como os momentos da emergência do conceito.


E: Esta alternativa está incorreta porque diz que o conceito surgiu no início do século 21. No entanto, o texto afirma que as ideias sobre jogadores robóticos foram introduzidas na década de 1990, muito antes do século 21.
