Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Simple learning rules to cope with changing environments

Roderich Gross

We consider an agent that must choose repeatedly among several actions. Each action has a certain probability of giving the agent an energy reward, and costs may be associated with switching between actions. The agent does not know which action has the hig ...

Division of Labour in Self-Organised Groups

Francesco Mondada, Michael Bonani, Roderich Gross

In social insect colonies, many tasks are performed by higher-order entities, such as groups and teams whose task solving capacities transcend those of the individual participants. In this paper, we investigate the emergence of such higher-order entities u ...

Performance Benefits of Self-Assembly in a Swarm-Bot

Francesco Mondada, Michael Bonani, Roderich Gross

Mobile robots are said to be capable of self-assembly when they can autonomously form physical connections with each other. Despite the recent proliferation of self-assembling systems, little work has been done on using self-assembly to add functional valu ...

Fifty years of self-assembly experimentation

Roderich Gross

In this paper, we review half a century of research on the design of systems displaying (physical) self-assembly of macroscopic components. We report on the experience gained in the study of 22 such systems, exhibiting components ranging from passive mecha ...

Moving targets: Collective decisions and flexible choices in house-hunting ants

Roderich Gross

Many decisions involve a trade-off between commitment and flexibility. We show here that the collective decisions ants make over new nest sites are sometimes sufficiently flexible that the ants can change targets even after an emigration has begun. Our fin ...

Autonomous Self-assembly in a Swarm-bot

Francesco Mondada, Michael Bonani, Roderich Gross

Multi-robot systems have been studied in tasks that require the robots to be physically linked. In such a configuration, a group of robots may navigate a terrain that proves too difficult for a single robot. On the contrary, many collective tasks can be ac ...

Self-assembly of mobile robots - From swarm-bot to super-mechano colony

Roderich Gross

Up to now, only a few collective or modular robot systems have proven capable of letting separate and autonomous units, or groups of units, self-assemble. In each case, ad hoc control algorithms have been developed. The aim of this paper is to show that a ...

Negotiation of goal direction for cooperative transport

Roderich Gross

In this paper, we study the cooperative transport of a heavy object by a group of robots towards a goal. We investigate the case in which robots have partial and noisy knowledge of the goal direction and can not perceive the goal itself. The robots have to ...

Autonomous Self-assembly in Swarm-Bots

Francesco Mondada, Michael Bonani, Roderich Gross

In this paper, we discuss the self-assembling capabilities of the swarm-bot, a distributed robotics concept that lies at the intersection between collective and self-reconfigurable robotics. A swarm-bot comprises autonomous mobile robots called s-bots. S-b ...

Cooperation through self-assembly in multi-robot

Francesco Mondada, Michael Bonani, Roderich Gross

This article illustrates the methods and results of two sets of experiments in which a group of mobile robots, called s-bots, are required to physically connect to each other, that is, to self-assemble, to cope with environmental conditions that prevent th ...
