Various detection methods for locating non-visible or concealed objects have been developed, but the accuracy of these has been limited to rough presumptions of position. Now, a dismantling robot with highly accurate positioning has been developed. This robot is designed to cut plasterboard that is fixed to light gauge steel with screws hidden under the plasterboard. A sensor with magnets has been designed to detect and trace this light gauge steel. The sensor incorporates a detecting mode and tracing mode to keep high position accuracy and high scanning speed. It was installed in the dismantling robot and tested for its ability to detect and trace the light gauge steel. Testing has proven this sensing system and design method to be highly successful and suitable for practical use.
