The collective directional movement of animals occurs over both short distances and longer
migrations, and is a critical aspect of feeding, reproduction and the ecology of many species …

Fish maintain high swimming efficiencies over a wide range of speeds. A key to this
achievement is their flexibility, yet even flexible robotic fish trail real fish in terms of …

Aquatic robotics is making a critical transition to adapt and inspire more efficient systems
from nature. The result is the abandonment of inefficient propeller-based locomotion for a …

Theory and modelling remain central to improving our understanding of undulatory and
oscillatory swimming. Simple models based on added mass can help to give great insight …

Numerical simulations are used to investigate the hydrodynamic benefits of body–fin and fin–
fin interactions in a fish model in carangiform swimming. The geometry and kinematics of the …

Through computational fluid dynamics (CFD) simulations of a model manta ray body, the
hydrodynamic role of manta-like bioinspired flap** is investigated. The manta ray model …

The effects of chordwise deformation and the half-amplitude asymmetry on the
hydrodynamic performance and vortex dynamics of batoid fish have been numerically …

Robotic systems are becoming more ubiquitous, whether on land, in the air, or in water. In
the aquatic realm, aquatic drones including ROVs (remotely operated vehicles) and AUVs …

Recent research on robotic fish mainly focused on the bionic structure design and realizing
the movement with smart materials. Although many robotic fish have been proposed, most of …

Finlets are a series of small non-retractable fins common to scombrid fishes (mackerels,
bonitos and tunas), which are known for their high swimming speed. It is hypothesized that …
