What's the best way to study a praying mantis' ability to see in 3D? By fitting it with a pair of 3D glasses of course! Scientists at Britain's Newcastle University developed the smallest pair of 3D glasses ever made to study the insects' 3D vision abilities and see if they could be of use in human technologies.
The tiny 3D glasses were placed in front of the praying mantis' eyes using beeswax as an adhesive. The mantises were then held in front of a computer screen, on which moving 3D targets were displayed. By studying the praying mantis' reactions to the stimuli, scientists can figure out if they process 3D imagery the same way humans do.
This knowledge will aid the development of human technologies involving robotic vision.
