Targeted worker removal reveals a lack of flexibility in brood transport specialisation with no compensatory gain in efficiency

Mahmut Selman Sakar, Laurent Keller, Fazil Emre Uslu

Division of labour is widely thought to increase the task efficiency of eusocial insects. Workers can switch their task to compensate for sudden changes in demand, providing flexible task allocation. In combination with automated tracking technology, we de ...

Robotic manipulation to investigate the physical principles of biological self-organization

Fazil Emre Uslu

Self-organization is the spontaneous formation of ordered patterns and networks from a population of comparatively simple elements or individuals with no prior information on neither the formation process nor the final organization. While the construction ...

Multiple nest entrances alter foraging and information transfer in ants

Bertrand Eric Collignon

The ecological success of ants relies on their ability to discover and collectively exploit available resources. In this process, the nest entrances are key locations at which foragers transfer food and information about the surrounding environment. We ass ...

Uncovering Latent Behaviors in Ant Colonies

Patrick Thiran, Matthias Grossglauser, Laurent Keller, Mohamed Kafsi, Raphaël Braunschweig

Many biological systems exhibit collective behaviors that strengthen their adaptability to their environment, compared to more solitary species. Describing these behaviors is challenging yet necessary in order to understand these biological systems. We pro ...

Ant Metaheuristics with Adapted Personalities for Vehicle Routing Problem

Rémy Glardon, Nicolas Zufferey, Jaime Farres

At each generation of an ant algorithm, each ant builds a solution step by step by adding an element to it. Each choice is based on the greedy force (short term profit or heuristic information) and the trail system (central memory which collects informatio ...

Tracking Individuals Shows Spatial Fidelity Is a Key Regulator of Ant Social Organization

Alessandro Crespi

Ants live in organized societies with a marked division of labor among workers, but little is known about how this division of labor is generated. We used a tracking system to continuously monitor individually tagged workers in six colonies of the ant Camp ...

Interest modeling in games: the case of dead reckoning

Kévin Clément Huguenin

In games, the goals and interests of players are key factors in their behavior. However, techniques used by networked games to cope with infrequent updates and message loss, such as dead reckoning, estimate a player's movements based mainly on previous obs ...

Evolution of division of labor in artificial societies

Pawel Lichocki

Natural and artificial societies often divide the workload between specialized members. For example, an ant worker may preferentially perform one of many tasks such as brood rearing, foraging and nest maintenance. A robot from a rescue team may specialize ...

Communication-based Swarming for Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

We aim at implementing a swarm of Micro-Air-Vehicles for creating communication networks (SMAVNETs) in disaster areas. For this purpose, we propose strategies for steering flying robots using only communication hardware (e.g. WiFi module or radio modem) an ...
