Praying mantises with tiny 3D glasses have stereo vision

Praying mantises sporting tiny 3D glasses that were held in place with beeswax have revealed a new kind of'stereo' vision that may help improve robot sight. With two teardrop-shaped, light-filtering lenses perched on their heads, the insects lashed out at images of tempting prey in a special 3D film, a team of scientists said. Currently robot algorithms for sight require a lot of computing power. However, if scientists could replicate the way mantis sight detects depth they could create more lightweight robots with better 3D vision.
