US Military's New Swarm of Mini-Drones


US military scientists have invented a miniature drone that fits in the palm of a hand, ready to be dropped from the sky like a mobile phone with wings.

The "micro air vehicle" is named after the insect that inspired its invention, the Cicada, which spends years underground before appearing in great swarms, reproducing and then dropping to the ground dead.

"The idea was why can't we make UAVs (unmanned aerial vehicles) that have the same sort of profile," Aaron Kahn of the Naval Research Laboratory told AFP.
