Micro-Robot Climbs on Vertical and Upside-Down Conductive Surfaces

Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take more than a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart. This problem is not confined to jet engines; many complicated, expensive machines like generators and scientific instruments require large investments of time and money to inspect and maintain.
