Evolving CAM-Brain to control a mobile robot

CAM-Brain is the model to create neural networks based on cellular automata, and ®nally aims at developing an arti®cial brain. In particular, this model can rapidly evolve the neural networks composed of several thousand modules with special purpose computers such as CAM-8 at MIT and CBM at ATR. This paper attempts to evolve a module of CAM-Brain for the problem to control a mobile robot, especially Khepera, which might show the feasibility of evolutionary engineering to develop an arti®cial brain. The original model has been modi®ed to solve a couple of problems which are caused by evolving CAM-Brain to control a mobile robot. Some preliminary experiments show the potential of CAM-Brain at the problem of control. Ó 2000 Elsevier Science Inc. All rights reserved.
