The robotic hummingbird is manufactured by AeroVironment of /*Monrovia*/. The nano bird is a pocket-sized drone that spies while it flies.
"This is the first aircraft that has been developed that flies with two flapping wings," explained Matt Keenon of AeroVironment.
The /*Defense Department*/ spent $4 million developing the battery-powered robotic birds.
The prototype has a wingspan of 6.5 inches, weighs two-thirds of an ounce and has a body fairing shaped like a real hummingbird.
AeroVironment was founded by the late Paul MacCready, designer of the pioneering human-powered flying machines Gossamer Condor and Gossamer Albatross. The company also makes unmanned military aircraft systems.
