Control Architecture for Cooperative Mobile Robots using Multi-Agent based Coordination Approach

National audienceThis paper is about a Multi-Agent based solution to control and coordinate team-working mobile robots moving in unstructured environments. Two main contributions are considered in our approach. The rst contribution of this paper is about the Multi-Agents System to Control and Coordinate teAmworking Robots (MAS2CAR) architecture, a new architecture to control a group of coordinated autonomous robots in unstructured environments. MAS2CAR covers three main layers: (i) the Physical Layer (ii) the Control Layer and (iii) the Coordination Layer. The second contribution of this paper is about the multi-agent system (MAS) organisational models aiming to solve the key cooperation issues in the coordination layer, the software components designed based on Utopia a MAS framework which automatically build software agents, thanks to a multi-agent based organisational model called MoiseInst . We provide simulation results that exhibit robotics cooperative behavior related to our scenario, such as multi-robots navigation in presence of obstacles (including trajectory planning, and reactive aspects) via a hybrid control

Reading "all about" computerization: five common genres of social analysis

This paper examines unstated, but critical, social assumptions which underlie analyses of computerization. It focuses on the popular, professional and scholarly literature which claims to describe the actual nature of computerization, the character of computer use, and the social choices and changes that result from computerization. This literature can be usefully segmented five ideal type genres: utopian, anti-utopian, social realism, social theory, and analytical reduction. Each genre is characterized and illustrated. The strengths and weaknesses of each genre are described. In the 1990s, there will be a large market for social analyses of computerization. Utopian analyses are most likely to domínate the popular and professional discourse. The empirically oriented accounts of social realism, social theory and analytical reduction, are likely to be much less common and also less commonly seen and read by computer professionals and policymakers. These genres are relatively subtle, portray a more ambiguous world, and have less rhetorical power to capture the imagination of readers. Even though they are more scientific, these empirically anchored genres don't seem to appeal to many scientists and engineers. It is ironic that computing -- often portrayed as an instrument of knowledge -- is primarily the subject of discourses whose knowledge claims are most suspect. Conversely, the discourses whose claims as valid knowledge are strongest seems to have much less appeal in the mass media and technological communities

Counter-Dancing Digitality: On Commoning and Computation

Digitality is imposed upon us! To change this, we should not turn away from it, but look carefully into its transformative power and make operable alternatives such as counter-algorhythms and solidarity-oriented commoning. The aim is a world where profit and property no longer exist, but instead where a cooperative dance - between all the needs posed by our ecosystems, and all the needs of people - becomes practicable. This book is a critical media theory of future-building, modulated by a focus on the potentials of counter-dancing as providing ways to unfold fugitive practices

Nam-Shub versus the Big Other: Revising the Language that Binds Us in Philip K. Dick, Neal Stephenson, Samuel R. Delany, and Chuck Palahniuk

Within the science fiction genre, utopian as well as dystopian experiments have found equal representation. This balanced treatment of two diametrically opposed social constructs results from a focus on the future for which this particular genre is well known. Philip K. Dick’s VALIS, Neal Stephenson’s Snow Crash, Samuel R. Delany’s Babel-17, and Chuck Palahniuk’s Lullaby, more aptly characterized as speculative fiction because of its use of magic against scientific social subjugation, each tackle dystopian qualities of contemporary society by analyzing the power that language possesses in the formation of the self and propagation of ideology. The utopian goals of these texts advocate for a return to the modernist metanarrative and a revision of postmodern cynicism because the authors look to the future for hopeful solutions to the social and ideological problems of today. Using Slavoj Žižek’s readings of Jacques Lacan and Theodor Adorno’s readings of Karl Marx for critical insight, I argue these four novels imagine language as the key to personal empowerment and social change. While not all of the novels achieve their utopian goals, they each evince a belief that the attempt belies a return to the modernist metanarrative and a rejection of postmodern helplessness. Thus, each novel imagines the revision of Žižek’s big Other through the remainders of Adorno’s inevitably failed revolutions, injecting hope in a literary period that had long since lost it
