Bridging Walking and Slithering – Stokesian Locomotion

Abstract

This a peer reviewed 1-page extended abstract for a talk given at the Dynamic Walking conference, 2021Both legged locomotion and slithering motions typically utilize periodic gaits – repeating cycles of body shape change that produce a net motion through the world. Legged locomotion can be viewed from the perspective of piecewise contact constraint formation and removal. Slithering and low Reynolds number swimming operate under continuous constraints of force balance, wherein dissipation removes the ability to accumulate momentum. Here we discuss how to bridge the gap between these domains of motion, thereby, among other benefits, producing models for the space of legged locomotion with slipping. The connective fabric is the use of a “Stokesian”, or “local connection” model.Army Research Office Defense University Research Instrumentation Program grant W911NF-17-1-0243 Army Research Office Multi University Research Initiative grant W911NF-17-1-0306 National Science Foundation Civil, Mechanical and Manufacturing Innovation grant 1825918 D.
