Praying mantises wear miniature 3D glasses to improve robot vision

If you thought praying mantises already look pretty cool, wait till you see them in these stunning shades.
Scientists who put tiny 3D glasses on these petite hunters have found that their stereoscopic vision system is unlike that of any other known animal.
The findings, described this week in the journal Current Biology, reveal how these remarkable insects have developed a sophisticated ability with such a tiny brain – and could prove useful in designing visual systems for future robots….
