Jens Krause’s research will be part of the behavioral biology component of SCIoI. He and his group have developed an interactive robotic fish which is recognised by live fish as a conspecific. This robot is used to investigate basic principles of collective behavior and collective cognition. In particular they are interested in the way in which group-living organisms process information to deal with environmental challenges and how they come to collective decisions that are adaptive. Their interactive robot can embody the algorithms that they identified in biological agents and thereby allows them to test their validity. In order to give their robots realistic behaviour (as fish) they address the issues of dimensionality reduction and cursive interaction which are central to SCIoI.
