Abstract

This paper deals with a recovery method of a crack shape for preventive maintenance of power plant. In order to detect a crack and recover of its shape automatically, we develop a mobile inspection robot with ECT (eddy current testing) sensor composed of a transmitter-receiver coil probe. ECT is a major technique for detection of surface and subsurface cracks found out in structures of the power plant. The robot detects crack by ECT sensor signals, localizes the crack and recover its shape by rough and fine inspection mode. For showing the effectiveness of this method, we show experimental results
