Artificial systems such as computers, robots and telecoms networks, collect information about and interact with the environments they inhabit. This raises the question of how to build artificial systems that adapt to their environment. The attempt to answer this question has brought together researchers from a broad range of theoretical and technological disciplines. Building an artifact that knows its environment requires on the one hand a Theory of Knowledge, on the other a broad range of scientific and technical know-how. In other words, it requires collaboration between psychologists, philosophers, biologists, engineers, computer scientists, physicists and mathematicians. The collaboration between these researchers in these different disciplines has already produced important theoretical and practical results. To further promote this collaboration, the EU has created a Network of Excellence, that brings together key workers in the area. The staff of the NAC laboratory is part of this effort. The focus of the lab's activity is to reproduce psychobiological phenomena in artificial systems using Evolutionary Robotics and Artificial Life techniques. Several of the key researchers come from the Laboratory for Adaptive Robotics and Artificial Life - Institute of Cognitive Sciences and Technologies National Research Council. Moreover, we are involved to extend this approach to create effective new technologies that support psychological processes (Learning, Decision Making, Entertainment, etc.- see our projects section).
