... a moving target from a mobile robot. González-Baños et al. [22] especially focus on the problem of tracking a moving target in the presence of obstacles. Additionally, Parker [49], Jung and Sukhatme =-=[31]-=-, Pirjanian and Matarić [50], and MurrietaCid et al. [48] present distributed approaches to control a team of mobile robots in order to maximize the visibility of moving targets. Whereas the focus of ...

...-Baños et al. [17] presented a modified version that works without a prior map of the environment. Furthermore, some multi-robot systems have been developed that keep track of multiple moving targets =-=[44, 25, 49]-=- or surround a moving target [50]. Riley and Veloso [52] use predefined opponent models in the RoboCup domain to reason about the opponents’ strategy and predict their behavior. Depending on the infer...

...ile there exist methods that do consider occlusion [8, 9], they still only consider situations where the target’s trajectory is known a priori, or are only applicable to follow a few (2 or 3) targets =-=[10, 11]-=-. Many researchers [12, 13, 14] have also considered the case where both trajectory and environment are unknown. The main idea of these motion planners is to greedily minimize the escaping risk or max...

Additionally, several multi-robot systems were developed that keep track of moving objects =-=[18, 9, 20]-=- or surround a moving target [21]. In the work presented by Rosencrantz et al. [23] a team of robots tries to locate and tag “enemies” which are not always in their perceptual field of view. They used...
