Mudskippers use tail thrusting to help crutching to move on mud of various wetness
Divya Ramesh, Gargi Sadalgekar, Jiangqi Tan +1
At the water-land interface, amphibious fishes encounter wet flowable substrates made of granular solid-water mixtures, which can stay solid or flow like a fluid. As these substrat…
Importance and methods to control, vary, and characterize mud strength for studying locomotion
Divya Ramesh, Gargi Sadalgekar, Qiyuan Fu +3
Animals and robots encounter mud at the water-land interface. Like sand, mud can stay solid or flow like a fluid. Unlike sand, the yield strength of mud at which solid-fluid transi…
SenSnake: A snake robot with contact force sensing for studying locomotion in complex 3-D terrain
Divya Ramesh, Qiyuan Fu, Chen Li
Despite advances in a diversity of environments, snake robots are still far behind snakes in traversing complex 3-D terrain with large obstacles. This is due to a lack of understan…
A resistive force model of legged locomotion on granular media
Chen Li, Tingnan Zhang, Daniel I. Goldman
Compared to agile legged animals, wheeled and tracked vehicles often suffer large performance loss on granular surfaces like sand and gravel. Understanding the mechanics of legged…
Towards a terramechanics for bio-inspired locomotion in granular environments
Chen Li, Yang Ding, Nick Gravish +6
Granular media (GM) present locomotor challenges for terrestrial and extraterrestrial devices because they can flow and solidify in response to localized intrusion of wheels, limbs…
A review on locomotion robophysics: the study of movement at the intersection of robotics, soft matter and dynamical systems
Jeffrey Aguilar, Tingnan Zhang, Feifei Qian +11
In this review we argue for the creation of a physics of moving systems -- a locomotion "robophysics" -- which we define as the pursuit of the discovery of principles of self gener…
Multi-functional foot use during running in the zebra-tailed lizard (Callisaurus draconoides)
Chen Li, S. Tonia Hsieh, Daniel I. Goldman
A diversity of animals that run on solid, level, flat, non-slip surfaces appear to bounce on their legs; elastic elements in the limbs can store and return energy during each step.…
The effect of limb kinematics on the speed of a legged robot on granular media
Chen Li, Paul B. Umbanhowar, Haldun Komsuoglu +1
Achieving effective locomotion on diverse terrestrial substrates can require subtle changes of limb kinematics. Biologically inspired legged robots (physical models of organisms) h…
A Terradynamics of Legged Locomotion on Granular Media
Chen Li, Tingnan Zhang, Daniel I. Goldman
The theories of aero- and hydrodynamics predict animal movement and device design in air and water through the computation of lift, drag, and thrust forces. Although models of terr…
