Integrating a Hierarchy of Simulation Tools for Legged Robot Locomotion
(Georgia Institute of Technology, 2008-09)
We are interested in the development of a variety
of legged robot platforms intended for operation in
unstructured outdoor terrain. In such settings, the traditions of
rational engineering design, driven by analytically ...
Kink-induced transport and segregation in oscillated granular layers
(Georgia Institute of Technology, 2003-09-26)
We use experiments and molecular dynamics simulations of vertically oscillated granular layers to study horizontal particle segregation induced by a kink (a boundary between domains oscillating out of phase). Counterrotating ...
Scaling and Dynamics of Sphere and Disk Impact into Granular Media
(Georgia Institute of Technology, 2008-02-29)
Direct measurements of the acceleration of spheres and disks impacting granular media reveal simple power law scalings along with complex dynamics which bear the signatures of both fluid and solid behavior. The penetration ...
Dynamics of drag and force distributions for projectile impact in a granular medium
(Georgia Institute of Technology, 2004-05-14)
Our experiments and molecular dynamics simulations on a projectile penetrating a two-dimensional granular medium reveal that the mean deceleration of the projectile is constant and proportional to the impact velocity. Thus, ...
Crucial role of sidewalls in velocity distributions in quasi-two-dimensional granular gases
(Georgia Institute of Technology, 2004-10-19)
Our experiments and three-dimensional molecular dynamics simulations of particles confined to a vertical monolayer by closely spaced frictional walls (sidewalls) yield velocity distributions with non-Gaussian tails and a ...
