Slow axial drift in three-dimensional granular tumbler flow
Zafir Zaman, Umberto D'Ortona, Paul B. Umbanhowar +2
Models of monodisperse particle flow in partially filled three-dimensional tumblers often assume that flow along the axis of rotation is negligible. We test this assumption, for sp…

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…
