Mole crab-inspired vertical self-burrowing
Frontiers in Robotics and AI, 2022 We present EMBUR—EMerita BUrrowing Robot—the first legged robot inspired by the Pacific mole crab, Emerita analoga, capable of burrowing vertically downward.

Robust self-propulsion in sand using simply controlled vibrating cubes
Frontiers in Robotics and AIMuch of the Earth and many surfaces of extraterrestrial bodies are composed of non-cohesive particulate matter. Locomoting on such granular terrain is challenging for common robotic devices, either wheeled or legged.

Spin-models of granular compaction: From one-dimensional models to random graphs
, 2001 We discuss two athermal types of dynamics suitable for spin-models designed to model repeated tapping of a granular assembly. These dynamics are applied to a range of models characterised by a 3-spin Hamiltonian aiming to capture the geometric ...

Toward a 3D physical model of diffusive polymer chains
Frontiers in Physics, 2023 Recent studies in polymer physics have created macro-scale analogs to solute microscopic polymer chains like DNA by inducing diffusive motion on a chain of beads.

, 2000 Stimulated by recent experimental results, we simulate ``temperature''-cycling experiments in a model for the compaction of granular media. We report on the existence of two types of memory effects: short-term dependence on the history of the sample, and

Avalanche Dynamics in Wet Granular Materials
, 2002 We have studied the dynamics of avalanching wet granular media in a rotating drum apparatus. Quantitative measurements of the flow velocity and the granular flux during avalanches allow us to characterize novel avalanche types unique to wet media.

Drag Induced Lift in Granular Media
Physical Review Letters, 2011 Laboratory experiments and numerical simulation reveal that a submerged intruder dragged horizontally at constant velocity within a granular medium experiences a lift force whose sign and magnitude depend on the intruder shape. Comparing the stress on a flat plate at varied inclination angle with the local surface stress on the intruders at regions ...

Motility of small nematodes in disordered wet granular media
, 2010 The motility of the worm nematode \textit{Caenorhabditis elegans} is investigated in shallow, wet granular media as a function of particle size dispersity and area density ($\phi$).

Continuum-type stability balloon in oscillated granular layers [PDF]
, 1998 The stability of convection rolls in a fluid heated from below is limited by secondary instabilities, including the skew-varicose and crossroll instabilities.
