Working with the Research Center for Advanced Science from the University of Tokyo, Nissan has developed the Robot Car BR23C.
This robot is based on bees and how in a swarm, they still avoid managing to crash into each other. Hopefully this technology will make it’s way into their cars by 2015.
In flight, bees have a safety shield similar to the one in the picture below. This is thanks to a bees compound eyes with 300 degrees of vision. See a video here.
