Going To War With Animal-Inspired Tech

  • <p>Before iRobot got in the vacuuming business with its Roomba, the company developed Ariel, a robot that could <a href="http://berkeley.edu/news/media/releases/2002/09/rfull/robots.html" target="_blank">search for mines in surf zones</a>. Its design was based on the humble crab, with legs that allow it to retain its balance when it encounters choppy water. If the surf topples its body, the legs can reorient themselves so the top of the bot becomes the bottom (and vice versa).</p>

  • 02 /08 | Sea Mollusk Body Armor

    From mimicking crabs to protecting against them, a deep sea-dwelling mollusk’s iron-reinforced shell could inspire the next generation of body armor. True, the materials used by the snail, calcium carbonate and iron, won’t stand up to bullets. But the tri-layer organization, if implemented with better lab-synthesized materials, could be incorporated into protective gear for armed forces and police officers.

    When the Morphos butterfly’s wings are exposed to various vapors, the light they reflect shifts to different parts of the color spectrum. DARPA wants to translate that biological response into small, counterterrorism sensors for detecting bombs and chemicals.

  • 08 /08 | Maple Tree Seeds As Nano Air Vehicles

    An engineer at Lockheed-Martin transformed his childhood fascination with the spiral of silver maple trees seeds as they fall to the ground into a tiny, remote-controlled air vehicle that can be used on a field of combat. The monocopter performs the seed’s trip in reverse, propelling upwards using a small rocket thruster. With a tiny transponder in its wing, the RoboSeed Nav could be used to relay communications between soldiers during military operations.

The military will look for innovations and advantages anywhere, including the natural world. From using artificial hummingbirds for surveillance to making body armor like snails make their shells, nature is providing inspiration for all sorts of mindblowing defense tech.
