Autonomous underwater vehicles (AUVs) are playing an ever-growing role in modern
subocean operations, generating a demand for faster, more manoeuvrable designs capable …

A new type of underwater thruster was designed to provide high-accuracy, low-speed
maneuvering to underwater robots. Located internal to the vehicle surface, these thrusters …

U-CAT is a highly maneuverable biomimetic four-fin underwater robot for operating in
confined spaces. Because of its novel mechanical design and specialized purpose, the …

A detailed series of experiments is performed to investigate the 'ground effect'experienced
by propulsive flap** foils operating near a solid boundary. A high aspect ratio foil is towed …

We show experimentally that flap** foil kinematics consisting of a power downstroke and
a feathering upstroke together with a properly timed in-line motion, similar to those …

The common guillemot, Uria aalge, a member of the auk family of seabirds exhibits
locomotive capabilities in both aerial and aquatic substrates. Simplistic forms of this ability …

Ocean sampling for highly temporal phenomena, such as harmful algal blooms,
necessitates a vehicle capable of fast aerial travel interspersed with an aquatic means of …

Inspired by the natural locomotion of jellyfish and squid, a series of compact thrusters series
is developed for propulsion and maneuvering of underwater vehicles. These thrusters …

Fin-actuated underwater robots usually control motion by changing the locomotion primitives
of the fins, such as frequency, amplitude, phase shift, or in more complicated cases also the …

The sea lion fore flipper has superior underwater movement performance. Its structural
characteristics and propulsion mechanism are drawn, combined with the large deformation …
