GE Global Research, in partnership with International Climbing Machines, have created the machine, which carries a high definition camera.
Additionally, the company is working on a microwave scanner that can be fitted onto the device, allowing inspectors to see beyond the surface and into the structure of the blade.
Waseem Faidi, GE Global Research manager said: "The inspection technology platform GE is developing with ICM provides a closer view of the turbine blade to detect repair and service needs.
"And in the future, GE researchers are working on technology that will allow inspectors to see through the blade materials and identify potential issues well in advance of any service needs. This all will mean faster diagnosis and repair – minimizing the risk of failure or forced down-time of the turbine."
