Autonomous robots use sensors to perceive and track objects in the world. Tracking algorithms use object motion models to estimate the position of a moving object. Tracking efficiency completely depends on the accuracy of the motion model and of the sensory information. Interestingly, when the robots can actuate the object being tracked, the motion can become highly discontinuous and nonlinear. We have previously developed a successful tracking approach that effectively switches among object

In this paper, we report on a tracking approach that can use a dynamic multiple motion model based on a team coordination plan. We present the multi-model probabilistic tracking algorithms in detail and present empirical results both in simulation and real robot test. Our physical team is composed of a robot and a human in a real Segway soccer game scenario. We show how the coordinated plan allows the robot to better track a mobile object through the effective interaction with its human teammate.
