Abstract

See full text

Systems, methods, and apparatus to provide artificial whisker filaments are disclosed and described. An example artificial whisker is tapered to include a tip diameter smaller than a base diameter of the artificial whisker, the artificial whisker formed from a polymer arranged to permit elastic deformation of the artificial whisker, the deformation of the artificial whisker to transmit force to a sensor associated with a base of the artificial whisker. An example method of manufacturing an artificial whisker includes removably affixing a first end of a filament to a heated, non-stick surface; drawing the filament across the surface to form a first, tapered portion, a second portion of the filament remaining on the surface, wherein the filament is to be drawn until the first portion is disengaged from the surface; and separating the first, tapered portion of the filament from the second portion of the filament to form a tapered artificial whisker.
