A Small Bioinspired Spy.

I read at Air & Space about a mini-copter spy inspired by maple seeds. That mini-copter will be used on spy actions made by military soldiers. But the project is still facing some technical problems, such as rotation stress and which thruster would be interesting to use.

That mini-copter is the first of its kind and was developed by the famous Skunk Works division from Lockheed Martin.

Tha small spy is another invention that reminds me Ingo Rechenberg's approach to solve (often difficult) problems and we should remember that evolutionary algorithms are bioinspired too.
