Soccer Robotics

This paper describes the activities of the research group Bahia Robotics Team (BRT) in preparation of the Bahia-PV team for the Physical Visualization(PV) Sub-League, disputed for the first time in RoboCup 2007 at Atlanta. In this paper we give an overview of this new sub-league, and present the proposal for the architecture and strategies of a robotic soccer team in PV environment. We also present new applications that explores the potentiality of the PV environment.

This paper presents the initial research results of Bahia Robotics
Team. This is a new research group created to investigate the application of artificial intelligence methods in the standard problem of robotics soccer.
In this work, fuzzy controllers are used to improve some abilities of the players. In the case of the attackers, the kick and the positioning ability were improved. The midfielders had their positioning and passing ability improved. The goalkeeper and the defenders had their positioning ability improved. The generated Bahia2D soccer team was tested in matches against some victorious teams from Robocup Brazil Open 2006 and from previous editions of the Robocup World Competition. The positive results achieved and the ongoing works to improve the current limitations are also presented.

This paper describes a research about fuzzy controllers for the positioning of the goalkeeper without the ball in the 2d simulated robot soccer. The goal of this research was to improve the behavior of the goalkeeper, raising the number of catches and decreasing the number of goals, improving its positioning to catch the ball. To validate the research, 30 matches were simulated against some of the best teams of the world that participate of the RoboCup. The achieved results are presented, the conclusions are discussed and future works are suggested.

Este artigo apresenta os resultados iniciais do grupo de pesquisa Bahia Robotics Team. Neste trabalho, controladores fuzzy são usados para melhorar algumas habilidades dos jogadores. Para os atacantes, o chute e o posicionamento foram aperfeiçoados. Os meiocampistas tiveram seu posicinamento e tomada de decisões abordados. Goleiro e defensores tiveram o posicionamento tratado. O passe de bola melhorou para todos os jogadores. O time gerado Bahia2D foi testado em partidas contra algumas equipes vitoriosas no Ropocup Brasil Open 2006 e em edições anteriores da competição mundial da Robocup. Apresenta também os resultados positivos obtidos até o momento, bem como os trabalhos em andamento para solucionar problemas que ainda são encontrados.
