Many tasks have still required human hand even in industry fields where automation technologies have been developed. Well-trained craftsworker's touch is indispensable. The aim of this study is the development of a finger-mounted tactile sensor. By mounting a sensor on finger, dexterous human fingers are applied to the sensing, it is easy to introduce into the task, and the intuitive sensing is given. A tactile sensor for small surface irregularity inspection was developed and real-time signal processing was introduced for detection and evaluation. Results show that the sensor can detect the surface irregularity and evaluate it relatively.
