SAN DIEGO (AP) — You’ll never look at hummingbirds the same again.
The Pentagon has poured millions of dollars into the development of tiny drones inspired by biology, each equipped with video and audio equipment that can record sights and sounds.
They could be used to spy, but also to locate people inside earthquake-crumpled buildings and detect hazardous chemical leaks.
The smaller, the better.
Besides the hummingbird, engineers in the growing unmanned aircraft industry are working on drones that look like insects and the helicopter-like maple leaf seed.
