Active oscillations in microscale navigation

KY Wan - Animal Cognition, 2023 - Springer
Living organisms routinely navigate their surroundings in search of better conditions, more
food, or to avoid predators. Typically, animals do so by integrating sensory cues from the …

The asymptotic coarse-graining formulation of slender-rods, bio-filaments and flagella

C Moreau, L Giraldi, H Gadêlha - Journal of the Royal …, 2018 - royalsocietypublishing.org
The inertialess fluid–structure interactions of active and passive inextensible filaments and
slender-rods are ubiquitous in nature, from the dynamics of semi-flexible polymers and …

The geometry of optimal gaits for drag-dominated kinematic systems

S Ramasamy, RL Hatton - IEEE Transactions on Robotics, 2019 - ieeexplore.ieee.org
In this paper, we present a set of geometric principles for understanding and optimizing the
gaits of drag-dominated kinematic locomoting systems. For systems with two shape …

A mixed-dimensional formulation for the simulation of slender structures immersed in an incompressible flow

F Lespagnol, C Grandmont, P Zunino… - Computer Methods in …, 2024 - Elsevier
We consider the simulation of slender structures immersed in a three-dimensional (3D) flow.
By exploiting the special geometric configuration of the slender structures, this particular …

Energy-optimal strokes for multi-link microswimmers: Purcell's loops and Taylor's waves reconciled

F Alouges, A DeSimone, L Giraldi, Y Or… - New Journal of …, 2019 - iopscience.iop.org
Micron-scale swimmers move in the realm of negligible inertia, dominated by viscous drag
forces. In this paper, we formulate the leading-order dynamics of a slender multi-link (N-link) …

Soap-bubble optimization of gaits

S Ramasamy, RL Hatton - 2016 IEEE 55th Conference on …, 2016 - ieeexplore.ieee.org
In this paper, we present a geometric variational algorithm for optimizing the gaits of
kinematic locomoting systems. The dynamics of this algorithm are analogous to the physics …

Symmetries and gaits for Purcell's three-link microswimmer model

E Gutman, Y Or - IEEE Transactions on Robotics, 2015 - ieeexplore.ieee.org
Robotic locomotion typically involves using gaits-periodic changes of kinematic shape,
which induce net motion of the body in a desired direction. An example is robotic …

Optimal gaits for drag-dominated swimmers with passive elastic joints

S Ramasamy, RL Hatton - Physical Review E, 2021 - APS
In this paper we identify optimal swimming strategies for drag-dominated swimmers with a
passive elastic joint. We use resistive force theory to obtain the dynamics of the system. We …

Local controllability of the two-link magneto-elastic micro-swimmer

L Giraldi, JB Pomet - IEEE Transactions on Automatic Control, 2016 - ieeexplore.ieee.org
A recent promising technique for robotic micro-swimmers is to endow them with a
magnetization and apply an external magnetic field to provoke their deformation. In this …
