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 that have the same sort of profile,” Aaron Kahn of the Naval Research Laboratory told AFP.

“We will put so many out there, it will be impossible for the enemy to pick them all up.”

The “Cicada”, short for Covert Autonomous Disposable Aircraft, was designed to be smaller, cheaper and simpler than any other robotic aircraft — but still able to carry out a mission in a remote battlefield.

The prototype cost just a thousand dollars, and the cost could come down to as little as $250 apiece, said Kahn, a flight controls engineer at the naval lab. With no motor and only about 10 parts, the Cicada resembles a paper airplane with a circuit board.

It is designed to glide to programmed GPS coordinates after being dropped from an aircraft, a balloon or a larger drone, researchers said.

In a test about three years ago in Yuma, Arizona, Cicada drones were released from 17,500 meters. The little drone flew — or fell — 11 miles, landing within 15 feet of its target.
