摘      要：This paper argues that for those neuronal systems which control behaviour, reliable responses are more appropriate than precise responses. We illustrate this argument using a mobile robot controlled by the responses of a neuronal model of the locust LGMD system, a visual system which responds to looming objects. Our experiments show that although the responses of the model LGMD Vary widely as the robot approaches obstacles, they still trigger avoidance responses. (C) 2001 Elsevier Science B.V.
