Abstract
Compositional ingredients of locomotion in living species interact to enhance survival. A major optimization indicator manifests within the detailed function of locomotor surfaces in many species. Surfaces highlight a design logic preserving the structural integrity of the surface and subsurface layers and energy conservation during motion. This chapter presents a comparative study of the topographical structure of three examples: human, canine, and feline-cat feet. It is shown that the metrological roughness of each of the examined feet is customized for the specific locomotion and energetic demands of the species. The textural parameters closely correlate to the pressure distribution experienced in movement. This enhances the durability and structural integrity of the bio-analogue.
