The neural controllers of creatures evolved for movement are augmented with simple visual neurons and neural connections. The resulting neural networks are trained for light following by an evolutionary algorithm. We show that, through this process, we are able to train the neural controllers to follow a light source. Many of the evolved behaviours show stability and adaptiveness to environmental perturbations of body orientation.engVisionvirtualtechnical report2008-901-1310.11575/PRISM/30862
