The Lockheed Martin 'Spider' is a robot that is capable of detecting and repairing pinhole leaks on hybrid airships. The Spider is meant to make the inspection process of the blimp's inflatable envelope more time-efficient and more accurate in detecting any tiny pinhole leaks.
Spider stands for "Self-Propelled Instrument for Damage Evaluation and Repair." The robot is capable of performing inspections while the aircraft is fully inflated and is far more accurate than any inspections done by humans. The robot uses LED lights and a camera to detect pinhole leaks and the Spider will re-position itself to be able to repair the leak. Photos of the pinhole leak before and after the patch are sent to a server for human inspection to double check the patch.
