Robots hearts will be able to creep anywhere. Even in aviation engines

Instead of the compressed air the device similar to an earthworm, uses electric charges wavy to move on a pipe. The plane engine — is a labyrinth of twisting, rotating pipes which transport liquids and gases on all car. It complicates survey of pipelines. The team of robototekhnik was inspired by the nature for development new, more effective method of diagnostics and aviation engines to prevent their breakage and ignition. Their invention — mechanical earthworms with the "muscles" made of dielectric elastomeric drives, and "feet"...
