Last month I reported on Atlas, the Cheetah and the Cougar 20-H robots that could detect people through walls by the sound of their breath and perform other feats of creepiness. Now design company TiaLinx, Inc. has developed a flying version: the Phoenix40-A.

The miniature unmanned hexacopter (a six-bladed helicopter), the Phoenix40-A can detect motion and breathing inside of a ground compound while flying. It can be controlled remotely over long distances — out of harm's way — by a person using a joystick or laptop controller.

The bot can penetrate reinforced concrete in a highly directed way by using a narrow beam of multi-gigahertz radio frequencies, in real time. It also has video cameras capable of imaging in day or night, and is lightweight and agile, all of which make the copter suited for surveillance in a variety of situations. Additionally, it can provide the layout of a multi-story building and travel to more than one GPS destination in a single trip. The copter even helps locate undetonated land mines.

But better yet, like its partner in team terror bot, the Cougar 20-H, the Phoenix40-A could serve less militant purposes, such as finding people buried in rubble during rescue missions. The United States Army provided funding to the California-based company in order to develop this latest option in life-detecting unmanned aerial vehicles (UAV's). Collect 'em all.
