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 insp...

Development of Crack Shape Inspection System with ECT Sensor Robot

This paper deals with an ECT diagnosis system using network communication. This system consists of an inspection module, a computational m odule and a communication interface module which can visualize some inspection results from the inspection module with ECT and some analys is results from the computation module. Here, three modules are connected through network architecture and communicated each other. Moreov er, an operator can control interactively the inspection and computational modules in order to...

Development of ECT Diagnosis System with Network Communication

This study deals with a crack detection method with a mobile robot for preventive maintenance of power plant. Eddy current testing (ECT) is a major technique for detection of c racks found out in structures of the power plant. In this paper, we develop a mobile robot with ECT sensor composed of a transmitter-receiver coil probe. The robot detects a cr ack by ECT sensor signals and localizes the crack by the position of the robot. Then, the robot traces the crack and reconstructs the shape of the crack. By ...
