Effective team-driven multi-model motion tracking

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 motion models as a function of the robot’s actions. If the object to be tracked is actuated by a team, the set of motion models is quite more complex. 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 ga...
