The Biological and Artificial Self-organized Systems (BASS) lab of the Free University of Brussels gathers an interdisciplinary team of biologists, computer scientists, and theoreticians working on collective behaviour in biological and artificial systems. The unit, which is part of the Center for Nonlinear Phenomena and Complex Systems, focuses on the experimental and theoretical study of social and gregarious species such as ants, cockroaches, fish, and others as well as on artificial systems with robot swarms and mixed societies with animal-robot interactions. In HIVEOPOLIS, our aim is to build mathematical models based on accumulated data to better understand, guide and predict collective behaviour of bee colonies.
