Abstract
A dismantling robot with highly accurate positioning has been developed. This robot is designed to cut plasterboard that is fixed to light gauge steel (LGS) 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. This paper studies the feasibility of position-detection for a small projected object represented by a screw on the LGS, and it shows the same method of the LGS detection is useful for screw detection.
