Machine with sticky feet which can can climb up, down, and all around jet engines

A robot with sticky feet that can climb up and down vertical walls as well as across the ceiling has been created by scientists. Harvard University engineers and Rolls-Royce partnered to make the robot which they say could inspect complex machines in the future. The device could be used in future to identify and maintain jet engines, scientific instruments and even generators. Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take over a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart, adding time and costs to maintenance.
