Lockheed Martin is serious about developing lighter-than-air vehicles, and now it has patented a new “spider” device that solves a maintenance problem for airship operators. Traditionally, teams of workers have been required to manually scan the airship envelope to find and repair tiny holes that couldn’t be found any other way. Now, Lockheed’s engineers have developed a small device, about the size of a Roomba autonomous home vacuum, that can travel over the entire surface of the envelope to find and repair any holes.
