A praying mantis could teach robots a thing or two about 3D machine vision

What's the best way to teach a robot or drone to see in 3D? Quite possibly, the answer is to teach it to think like an insect. A praying mantis, to be more specific. A team at the Institute of Neuroscience at Newcastle University recently studied the stereoscopic vision of the praying mantis and found that its approach to depth perception is quite different than ours. And what do you need to study praying mantises' 3D vision? The team, led by behavioral ecologist Dr. Vivek Nityananda, discovered that mantis 3D vision works differently from all previously known forms of biological 3D vision.
