The methodology of the artificial

Biorobotics research should not only target >realistic> models of living systems and be judged exclusively from that perspective. It should pay just as much attention to formal models and artificial systems. They allow the examination of assumptions which do not necessarily hold for living systems, but precisely therein lies their value. They generate insight by enabling a comparison between the artificial and the real.Funding from a governmental GOA project to the VUB AI Lab and CNRS-OHLL project to Sony CSL is gratefully acknowledged.Peer Reviewe
