概要

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 shap e automatically, we develop a mobile robot with ECT (Eddy Current Testing) sensor composed of a transmitter-receiver coil probe. ECT is a major techn ique for detection of surface and subsurface cracks found out in structures of the power plant. The robot detects a crack by ECT sensor signals, local izes the crack and recover its shape by rough and fine inspection mode. For showing the effectiveness of this method, we show a experimental results.
