Novel robot mimics insects’ optics-to-neurons pathway

With a brain the size of a pinhead, insects perform fantastic navigational feats. They avoid obstacles and move through small openings. How do they do this with their limited brain power? Understanding the inner workings of an insect's brain can help us in our search towards energy-efficient computing; physicist Elisabetta Chicca of the University of Groningen demonstrates with her most recent result: a robot that acts like an insect.
