     View Summary

    <p>We propose a new model for tactile perception of the finger pad of a human based on the stick-slip vibration. It is known that a frequency of the stick-slip vibration to occur on the contact surface of two hard substances depends on the relative speed to each other, the load applied on the contact surface and the difference between the coefficients of static and kinetic friction. We suppose that similar dependence can be applied to the finger pad with a fingerprint. The validity of our model is shown from the both of an experiment and a numerical simulation. In the experiment, a rubber board with stripe and rectangular shapes is used instead of the fingerprint to get a relationship between the surface roughness and the relative speed, the load on the contact surface and the frequency of stick-slip vibration. As a result, it is shown that the stick-slip vibrations with the same frequency occur in a particular range of the relative speed V and the load W. In the numerical simulation, one-dimensional beam model corresponding to an elastic body with rectangular shapes is investigated in the case of acting only a horizontal shear force. It is shown that the frequency change of stick-slip vibration is remarkable in the range of a small value of <i>V/W</i>.</p>

  • Experiment on route selection behavior of ant Camontus japonicus in foraging activity

     View Summary

    We conducted an experiment on the route selection behavior of comontus japonicus ant. The feeding spot and the entrance of the ant's colony are set at the both ends of the planar area surrounded by the acrylic case. All ants's routes recorded by the video camera were analysed by a computer. The converged routes formation were confirmed in two cases in a series of experiments. The trajectory and the temporal evolution of velocity of each ant were obtained. The frequency distribution of walking velocity and the moving distance ratio were also examined.
