Design and implementation of fuzzy ring univector field for robot soccer game

In this paper, the fuzzy ring univector field (FRUF) scheme is proposed for mobile robot to accomplish the obstacle-avoidance and goal-reaching missions. Application of FRUF method to the robot soccer game is also examined. According to the laws of F180 league of RoboCup, the active robots are not allowed to push the inactive robot a width of robot away when colliding. Tackling these problems, we also provide the ring univector field (RUF) in comparisons with the FRUF approach and the commonly used univector field method. The shooting action is incorporated to score a goal. Both computer simulations and experimental results illustrate that the proposed schemes can not only chase the ball and avoid collision with opponents but also successfully kick the ball in a real-time robot soccer game.
