The hydrodynamics of eel swimming: I. Wake structure.
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, we examine in detail the hydrodynamics of American eels (Anguilla rostrata) swimming steadily at 1.4 L s(-1) and compare them with previous results from other fishes. We performed high-resolution particle image veloci...
متن کاملThe hydrodynamics of eel swimming II. Effect of swimming speed.
Simultaneous swimming kinematics and hydrodynamics are presented for American eels, Anguilla rostrata, swimming at speeds from 0.5 to 2 L s(-1). Body outlines and particle image velocimetry (PIV) data were collected using two synchronized high-speed cameras, and an empirical relationship between swimming motions and fluid flow is described. Lateral impulse in the wake is estimated assuming that...
متن کاملThe eel-like robot
The aim of this project is to design, study and build an " eel-like robot " prototype able to swim in three dimensions. The study is based on the analysis of eel swimming and results in the realization of a prototype with 12 vertebrae, a skin and a head with two fins. To reach these objectives, a multidisciplinary group of teams and laboratories has been formed in the framework of two French pr...
متن کاملKinematic Analysis of the vertebra of an eel like robot
The kinematic analysis of a spherical wrist with parallel architecture is the object of this article. This study is part of a larger French project, which aims to design and to build an eel like robot to imitate the eel swimming. To implement direct and inverse kinematics on the control law of the prototype, we need to evaluate the workspace without any collisions between the different bodies. ...

Acknowledgements My sincerest thanks go out to the following people—some were involved in starting me off on this road, others in keeping me going and others still in pushing me to the destination. gave me enough rope and always had faith—even when mine was waning. To Konrad Scheffler, who acted as advisor and sounding board and whose ability is surpassed only by his willingness. Professor Ben ...
