Discrimination of particles has been investigated by using tactile information in an artificial system. Two kinds of time-series signals, i.e. normal and tangential fluctuations, were obtained experimentally when two silicone-gum specimens were rubbed with particles (diameter: 20-710μm). The particle diameters were found to be correlated with two quantities obtained from the time-series signals, i.e. the elastic recovery and the weighted mean frequency. By using the relationship between the two quantities and the particle diameters, the artificial system showed an ability of discrimination comparable with human subjects. Information of the size of sands appears in three ways. In case of larger-size samples, it appears strongly in the weighted mean frequency with lower-range frequency. On the contrary, it appears strongly in the elastic recovery for middle-size samples, and in the weighted mean frequency with higher-range frequency for smaller-size samples. By considering such characteristics, an algorithm has been constructed for discriminating the all samples with a higher accuracy, which has a similarity to the functions of three kinds of tactile receptors.
