Coordinated by the Service d’écologie sociale of the Université libre de Bruxelles in the frame of the European project « Leurre », the research has experimentally demonstrated the possibility to realize mixed groups of cockroaches and robots making the choice of shared shelter.
The researchers have observed collective behaviours based on self-organization in different group-living animals, from insects to vertebrates. Those findings in biology have stimulated engineers to study the possibility to use these models to elaborate multirobots systems based on self-organization.
The study presented in Science (11/16/07) combines those two aspects : it shows that individuals, natural or artificial, are all perceived as equivalent. The collective decisions emerges from nonlinear feedbacks based on local interactions. Even when in the minority, robots are able to modulate the collective behaviour of the mixed groups and to produce shelter choices non-observed in their absence.
Led by the ULB (Service de écologie sociale), the Ecole polytechnique fédérale de Lausanne (EPFL) and biologists from the CNRS at the Université de Rennes 1, the research demonstrates for the first time the possibility to use autonomous artificial agents to study and control self-organized social behaviour in group-living animals.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
