" Exploration and search " is a typical task for autonomous robots performing in rescue missions, specifically addressing the problem of exploring the environment and at the same time searching for interesting features within the environment. In this paper, we model this problem as a multi-objective exploration and search problem and present a prototype(More)
In this paper we present a novel representation framework based on Petri Nets for describing robot and multi-robot behaviors. The Petri Net Plan (PNP) formalism allows for high level description of complex action interactions that are necessary in programming cognitive robots: non-instantaneous actions, sensing and conditional actions, action failures,(More)
In this paper we present an asynchronous distributed mechanism for allocating tasks in a team of robots. Tasks to be allocated are dynamically perceived from the environment and can be tied by execution constraints. Conflicts among team mates arise when an uncontrolled number of robots execute the same task, resulting in waste of effort and spatial(More)
Intense efforts to define a common structure in robotic applications, both from a conceptual and from an implementation point of view, have been carried out in the last years and several frameworks have been realized for helping in developing robotic applications. However, due to the diversity of these applications, as well as of the research groups(More)
We describe an approach to reasoning agents which is based on a formal theory of actions and is actually implemented on a mobile robot working in an ooce environment. From an epistemological viewpoint, our proposal is originated by the correspondence between Dynamic Logics and Description Logics. Speciically, we consider an epistemic extension of(More)
The need for improving the robustness and the ability to adapt to different operational conditions is a key requirement for a wider deployment of robots in many application domains. To this end, uses of contextual information have proven to be effective in many robotic applications. In this paper, we present a case study on the use of contextual information(More)
Multi Robot Systems are, nowadays, an important research area within Robotics and Artificial Intelligence. Although Multi Robot Systems can be regarded as a particular case of Multi Agent Systems, it seems appropriate to study the Multi Robot Systems from a specific viewpoint, because of the issues which arise from the embodiment of agents operating in real(More)
