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

Integral line-of-sight path following control of magnetic helical microswimmers subject to step-out frequencies
A Mohammadi, MW Spong - Automatica, 2021 - Elsevier
This paper investigates the problem of straight-line path following for magnetic helical
microswimmers. The control objective is to make the helical microswimmer to converge to a …

The swimming of a deforming helix
Many microorganisms and artificial microswimmers use helical appendages in order to
generate locomotion. Though often rotated so as to produce thrust, some species of bacteria …

Controlling non-controllable scallops
A swimmer embedded on an inertialess fluid must perform a non-reciprocal motion to swim
forward. The archetypal demonstration of this unique motion-constraint was introduced by …

A neutrally stable shell in a Stokes flow: a rotational Taylor's sheet
In a seminal paper published in 1951, Taylor studied the interactions between a viscous
fluid and an immersed flat sheet which is subjected to a travelling wave of transversal …
