On the control of a wheeled mobile robot goalkeeper

This paper deals with the control of a wheeled mobile robot goalkeeper, where the goalkeeper's task is to intercept the ball before it goes inside the goal. The control law is based on the use of the kinematics equations and some geometrical rules. In our control strategy, the goalkeeper moves in a predefined path which corresponds to a rendezvous course. The goalkeeper is controlled in the linear velocity to intercept the ball. We consider various simulation examples.
