Invited Talks

Distibuted Robotics and Sensor-Actuator Networks
Gaurav Sukhatme
University of Southern California, USA
Wireless communication technology has altered robotics. Examples include distributed robot systems that solve a diverse set of problems (e.g. localization, coverage, navigation, task allocation) in some cases using a network of immobile sensors. I will discuss and characterize the algorithms we have devised for some of these tasks. I will argue that robotics can potentially alter the way wireless sensor networks are deployed, maintained, repaired, and replenished, illustrating once again with experimental prototypes.


Swarm-bot: A novel type of self-assembling robot
Marco Dorigo
Université Libre de Bruxelles, Belgium
Swarm robotics is an emergent field of collective robotics that studies robotic systems composed of swarms of robots tightly interacting and cooperating to reach their goals. In this talk I will report on work we carried out within the SWARM-BOTS project, a project funded by the Future and Emerging Technologies program of the European Commission. This work is directly inspired by the collective behavior of social insects colonies and other animal societies. In particular, it focuses on the study of the mechanisms which govern the processes of self-organisation and self-assembling in artificial autonomous agents. In order to pursue these objectives, a new type of robot, called s-bot, has been developed. The s-bots are mobile robots with the ability to connect to and to disconnect from each other. A swarm-bot is defined as an artifact composed of a swarm of assembled s-bots. S-bots have relatively simple sensors and motors and limited computational capabilities. Their physical links are used to assemble into a swarm-bot able to solve problems that cannot be solved by a single s-bot. In the swarm-bot form, the s-bots are attached to each other and, when needed, become a single robotic system that can move and reconfigure. In the talk I will not only describe the hardware and control algorithms that we developed, but also present many recent results concerning coordinate movement, path formation, and collective transport.
