Organisms such as bees and flies are superb at visually-guided navigation in real-world environments. We have implemented visual motion processing algorithms inspired by the visual systems of insects in custom analog/digital VLSI vision chips. In this paper we describe the implementation and operation of these algorithms, and discuss how these vision chips may be applied to practical problems of airborne visually-guided navigation.
