CONCLUSIONCONCLUSION
The robot was able to achieve the following goals: adhering to and walking over an aircraft fuselage regardless of the orientations of those surfaces, acquiring eddy-current inspection data that appeared identical to manually deployed eddy-current sensors, and being remotely operated using video and sensor feedback provided to the inspector. Video camera-based automatic alignment and navigation were demonstrated in an auxiliary experiment using a separate robot moving on an aircraft skin surface.
