How accurate need sensory coding be for behaviour? Experiments using a mobile robot

摘要

this paper argues that for those neuronal systems witch control behaviour, reliable re- sponges 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.
