Pioneer approaches to Artificial Intelligence have traditionally neglected, in a chronological sequence, the agent body, the world where the agent is situated, and the other agents. With the advent of Collective Robotics approaches, important progresses were made toward embodying and situating the agents, together with the introduction of collective(More)
The concept of environment is of paramount relevance for new strategies to model systems of multiple artificial agents. This paper introduces a set of definitions designed to guide the modelling of institutional environments. This is part of ongoing research on a new strategy to conceptualize multi-robot systems, which takes a network of institutions as the(More)
This work is developed in the framework of Institutional Robotics (IR), an approach to cooperative distributed robotic systems that draws inspiration from the social sciences. We consider a case study concerned with a swarm of simple robots which has to maintain wireless connectivity and a certain degree of spatial compactness. Robots have local, bounded(More)
The work described is part of a long term program of introducing institutional robotics, a novel framework for the coordination of robot teams that stems from institutional economics concepts. Under the framework, institutions are cumulative sets of persistent artificial modifications made to the environment or to the internal mechanisms of a subset of(More)
Institutional robotics (IR) is an approach to the coordination of multirobot systems that draws inspiration from social sciences, namely from institutional economics. Using the concept of institution, it aims to provide a comprehensive strategy for specifying social interactions (e.g., norms, roles, hierarchies) among robots. In previous work, we have(More)
Institutional Robotics is a new approach to the coordination of distributed robotic systems, drawing inspiration from social sciences. It aims to provide a comprehensive strategy for specifying social interactions among robots in the form of institutions. In this paper, we present a formalism for institutions in the Institutional Robotics model. We apply(More)
With the increasing availability of high-performance massively parallel computer systems, sophisticated scientific simulation has grown rapidly. Besides, the fast growth of high bandwidth wide area networks has allowed the use of PC clusters and/or multiprocessors machines. In order to handle the complexity of such applications, software component(More)
