 Among the arthropods, some spiders have similar setae on their scopulae or scopula pads, enabling them to climb or hang upside-down from extremely smooth surfaces such as glass or porcelain.In May 2014, DARPA demonstrated the latest iteration of its "Geckskin" technology by having a 100 kg researcher (saddled with 20 kg of recording gear) scale an glass wall using only two climbing paddles.Tests are ongoing, but DARPA hopes one day to make the technology available for military use, giving soldiers Spider-Man-like abilities in urban combat.
