In this research, we propose a scanning haptic sensor that can be used for surface inspection. Minute irregularities on a wide surface must be found in surface inspection. Therefore, we propose a planar scanning haptic sensor with a wide inspection width when user trace once. This sensor has two long strain gauges arranged in parallel. It is easy to detect the signal due to minute irregularities by superimposing the signals of two strain gauges. As prototype, the haptic sensor with an inspection width of 60 mm is fabricated. In this paper, the minute irregularity is defined as a convex of Gaussian-shape that has height of 50 μm and wide of 3mm. We show by experiments that the proposed sensor can detect minute convex.
