Abstract

Rodents can recognize objects by using their whiskers. Not only rodents but also mammals use their whiskers to recognize objects. However, rodents can discriminate surface roughness in micrometer resolution throughout their whisker sensing. Rats can distinguish an target object's shape, roughness and surface pattern by moving their whisker back and forth freely. Mechanoreceptors surrounding the whisker in their follicle measure deflection and vibration of the whisker. In this paper, we designed biomimetic whiskers modeling rodent whiskers and showed the characteristic properties to extract the information of surface roughness.
