Odd elasticity in a three-link microswimmer: feedback equivalence, global controllability, and the cost of non-reciprocity
Rossella Attanasi, Gaetano Napoli, Marta Zoppello
We study a Purcell three-link microswimmer whose joints are \emph{odd-elastic}: the torsional stiffness is non-Hermitian, its antisymmetric part injecting mechanical work so…
Purcell swimmer near a wall
Enrico Micalizio, Marco Morandotti, Henry Shum +1
We study the effects of hydrodynamic interactions between a wall and the Purcell three-link swimmer in the two-dimensional case. After deriving the equations of motion in a low Rey…
Controllability and Displacement Analysis of a Three-Link Elastic Microswimmer: A Geometric Control Approach
Rossella Attanasi, Marta Zoppello, Gaetano Napoli
This study investigates the dynamics and controllability of a Purcell three-link microswimmer equipped with passive elastic torsional coils at its joints. By controlling the sponta…
Controllability and kinetic limit of spherical particles immersed in a viscous fluid
Marta Zoppello, Henry Shum, Marco Morandotti
This paper deals with systems of spherical particles immersed in a viscous fluid. Two aspects are studied, namely the controllability of such systems, with particular attention to…
