Geckos inspire new wall climbing devices

Gecko-inspired paddles have been invented allowing a full-grown human adult to climb up a wall of glass!

The United States Defense Advanced Research Projects Agency (DARPA) announced on June 5, 2014 that a 218-pound climber climbed up and down a 25-foot tall glass wall while caring an additional pound 50-pound load. The climb was made possible due to the use of a pair of hand-held, gecko-inspired paddles.

Geckos can climb on a wide variety of surfaces, including smooth surfaces like glass due to the nano-sized structures on their toes. These structures are very small - there are a billion nanometers in a meter.

The gecko-inspired addles were created using nanotechnology.

Technologies such as these biologically inspired climbing devices could make it possible for soldiers to scale vertical walls without ladders. DARPA's mission is to create breakthrough technologies for national security.
