Superlinear Physical Performances in a SWARM-BOT

Dario Floreano, Francesco Mondada, Michael Bonani, Stéphane Magnenat, Christoph Studer, André Guignard

A swarm-bot is a robotic entity built of several autonomous mobile robots (called s-bots) physically connected together. This form of collective robotics exploits robot interactions both at the behavioral and physical levels. The goal of this paper is to a ...

Autonomous Exploration for Radioactive Hotspots Localization Taking Account of Sensor Limitations

Francesco Mondada, Hadi Ardiny, Stefan John Witwicki

Effective radioactive hotspot localization and detection is limited by sensor characteristics (i.e., the long acquisition time and poor angular resolution AR of a gamma camera) that significantly degrade the performance of autonomous exploration in terms o ...

TRIPILLAR: Miniature magnetic caterpillar climbing robot with plane transition ability

Francesco Mondada, Roland Moser, Frédéric Rochat, Patrick Schoeneich

We present a miniature magnetic climbing robot with dimensions 96 x 46 x 64mm(3). With two degrees of freedom it is able to climb ferromagnetic surfaces and to make inner plane to plane transitions whatever their inclination is. This robot, named TRIPILLAR ...

Towards Autonomous Energy-Wise RObjects

Alcherio Martinoli, Francesco Mondada, Michael Bonani, Philippe Rétornaz, Florian Christopher Vaussard

In this article, the RObject concept is first introduced. This is followed by a survey of applicable energy scavenging technologies. Energy is a key issue for the large scale deployment of robotics in daily life, as recharging the batteries places a consid ...

A Social Approach for Target Localization: Simulation and Implementation in the marXbot Robot

Francesco Mondada, Andres Perez-Uribe, Philippe Rétornaz, Andres Upegui

Foraging is a common benchmark problem in collective robotics in which a robot (the forager) explores a given environment while collecting items for further deposition at specific locations. A typical real-world application of foraging is garbage collectio ...

Swarm-bots to the Rescue

Francesco Mondada, Michael Bonani

We explore the problem of resource allocation in a system made up of autonomous agents that can either carry out tasks individually or, when necessary, cooperate by forming physical connections with each other. We consider a group transport scenario that i ...

Design of Magnetic Switchable Device (MSD) and applications in climbing robot

Francesco Mondada, Hannes Bleuler, Michael Bonani, Stéphane Magnenat, Frédéric Rochat, Patrick Schoeneich

A Magnetic Switchable Device (MSD) is a ferromagnetic circuit using permanent magnets where the flux can circulate between different paths when its configuration is changed. This routes or cancels the flux through specific surfaces, and thus turns on or of ...
