The use of machine learning techniques in the development of microscopic swimmers has
drawn considerable attention in recent years. In particular, reinforcement learning has been …

The process of swimming at the microscopic scale is successfully described as a finite-
dimensional, nonholonomic control system due to negligible inertia in the low-Reynolds …

The observations of microorganisms revealed how they swim. As inspired by them, studies
on artificial micro-robots with various actuation mechanisms have been thriving. To elucidate …

Ionic polymer-metal composites (IPMCs) are electrically driven materials that undergo
bending deformations in the presence of relatively low external voltages, exhibiting a great …

Micro-organisms encounter heterogeneous viscous environments consisting of networks of
obstacles embedded in a viscous fluid medium. In this paper we analyse the characteristics …

Locomotion of biological and artificial microswimmers has received considerable attention
due to its fundamental biological relevance and promising biomedical applications such as …

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) …

The wheeled three-link snake model is a well-known example of an underactuated robotic
system whose motion can be kinematically controlled by periodic changes of its internal …

In this paper, we study the swimming of a model organism, the so-called Taylor's swimming
sheet, in a viscoelastic fluid close to a solid boundary. This situation comprises natural …

Micro-organisms expend energy moving through complex media. While propulsion speed is
an important property of locomotion, efficiency is another factor that may determine the …
