▪ Abstract Interest in novel forms of marine propulsion and maneuvering has sparked a
number of studies on unsteadily operating propulsors. We review recent experimental and …

Underwater robot designs inspired by the behavior, physiology, and anatomy of fishes can
provide enhanced maneuverability, stealth, and energy efficiency. Over the last two …

In this work we describe an autonomous soft-bodied robot that is both self-contained and
capable of rapid, continuum-body motion. We detail the design, modeling, fabrication, and …

Tunas are flexible, high-performance open ocean swimmers that operate at high
frequencies to achieve high swimming speeds. Most fish-like robotic systems operate at low …

The development of autonomous, energy efficient, underwater robots for large areas
exploration has been attracting many researchers, since their use can be effective in several …

Classifications of fish swimming are reviewed as a prelude to discussing functional design
and performance in an ecological context. Webb (1984a, 1998) classified fishes based on …

We employ numerical simulation to investigate the hydrodynamics of carangiform
locomotion as the relative magnitude of viscous and inertial forces, ie the Reynolds number …

Eels undulate a larger portion of their bodies while swimming than many other fishes, but the
hydrodynamic consequences of this swimming mode are poorly understood. In this study …

To evaluate the swimming performances of aquatic animals, an important dimensionless
quantity is the Strouhal number, St= fA/U, with f the tail-beat frequency, A the peak-to-peak …

This paper is concerned with the design of a robotic fish and its motion control algorithms. A
radio-controlled, four-link biomimetic robotic fish is developed using a flexible posterior body …
