摘要: Research on the visual behavior of insects has uncovered a number cues that are used for controlling and stabilizing flight extracting information about structure environment. Flies monitor their egomotion maintain straight course by sensing patterns image motion induced in eyes. Bees flying through tunnel equidistance to flanking walls balancing speeds images two walls. This enables them safely negotiate narrow passages or fly between obstacles. The speed is controlled holding constant average velocity as seen 2 ensures bee slows down safer when passage narrows. landing horizontal surface hold they approach it, thus automatically ensuring close 0 at touchdown. bees distinguish objects from backgrounds relative images...
