Humans obtain a tactile feeling when they rub a surface of an object. The feeling is associated with some properties of the object, therefore they obtain some information about it by tactile sensation. For example, humans memorize the tactile feeling of five kinds of sand particles with different mean diameters of 0.24−0.66 mm, and discriminate them precisely to some extent by using the slight differences in their tactile feelings. An artificial system has been constructed for obtaining signals induced by friction with sand particles between sliding surfaces. The signals are found to contain the information about particle size, and the system discriminates the five kinds of sand particles comparably with humans.
