Modular Lorentz Force Actuators for Efficient Biomimetic Propulsion of Autonomous Underwater Vehicles

Modular Lorentz Force Actuators for Efficient Biomimetic Propulsion of Autonomous Underwater Vehicles PDF Author: Joseph Christopher Church

Pages : 63

Book Description
In this thesis, we developed a highly scalable design for modular Lorentz force actuators for use in segmented flexible-hull undersea vehicles such as the RoboTuna being developed at Franklin W, Olin College of Engineering. The actuators were designed to directly drive tail foil sections, or vertebrae, in an oscillatory motion to provide thrust. The design process was automated to facilitate implementation in different sized vertebrae. A set of prototype actuators was manufactured and tested to evaluate the feasibility of the design. A test stand was constructed to evaluate both the static and dynamic performance of the actuators. The prototype actuators achieved the required motion and demonstrated modest performance at a variety of load levels.

Motion Control of Biomimetic Swimming Robots

Motion Control of Biomimetic Swimming Robots PDF Author: Junzhi Yu
Publisher: Springer
ISBN: 9811387710
Category : Technology & Engineering
Languages : en
Pages : 203

Book Description
This book reports on the latest advances in the study of motion control in biomimetic swimming robots with high speed and high manoeuvrability. It presents state-of-the-art studies on various swimming robots including robotic fish, dolphins and jellyfish in a unified framework, and discusses the potential benefits of applying biomimetic underwater propulsion to autonomous underwater vehicle design, such as: speed, energy economy, enhanced manoeuvrability, and reduced detectability. Given its scope, the book will be of interest to researchers, engineers and graduate students in robotics and ocean engineering who wish to learn about the core principles, methods, algorithms, and applications of biomimetic underwater robots.

Biomimetic Oscillating Foil Propulsion to Enhance Underwater Vehicle Agility and Maneuverability

Biomimetic Oscillating Foil Propulsion to Enhance Underwater Vehicle Agility and Maneuverability PDF Author: Stephen Carl Licht
Publisher:
ISBN:
Category : Ocean engineering
Languages : en
Pages : 216

Book Description
Inspired by the swimming abilities of marine animals, this thesis presents "Finnegan the RoboTurtle", an autonomous underwater vehicle (AUV) powered entirely by four flapping foils. Biomimetic actuation is shown to produce dramatic improvements in AUV maneuvering at cruising speeds, while simultaneously allowing for agility at low speeds. Using control algorithms linear in the modified Rodrigues parameters to support large angle maneuvers, the vehicle is successfully controlled in banked and twisting turns, exceeding the best reported AUV turning performance by more than a factor of two; a minimum turning radius of 0.7BL, and the ability to avoid walls detected> 1.8BL ahead, are found for cruising speeds of 0.75BL/s, with a maximum heading rate of 400/s recorded. Observations of "Myrtle", a 250kg Green sea turtle (Chelonia mydas) at the New England Aquarium, are detailed; along with steady swimming, Myrtle is observed performing 1800 level turns and rapidly actuating pitch to control depth and speed. Limb kinematics for the level turning maneuver are replicated by Finnegan, and turning rates comparable to those of the turtle are achieved. Foil kinematics which produce approximately sinusoidal nominal angle of attack trace are shown to improve turning performance by as much as 25%; the effect is achieved despite limited knowledge of the flow field. Finally, tests with a single foil are used to demonstrate that biomimetically inspired inline motion can allow oscillating foils utilizing a power/recovery style stroke to generate as much as 90% of the thrust from a power/power stroke style motion.

Marine Robotics and Applications

Marine Robotics and Applications PDF Author: Luc Jaulin
Publisher: Springer
ISBN: 3319707248
Category : Technology & Engineering
Languages : en
Pages : 186

Book Description
This book reports on findings at the intersection between two related fields, namely coastal hydrography and marine robotics. On one side, it shows how the exploration of the ocean can be performed by autonomous underwater vehicles; on the other side, it shows how some methods from hydrography can be implemented in the localization and navigation of such vehicles, e.g. for target identification or path finding. Partially based on contributions presented at the conference Quantitative Monitoring of Underwater Environment, MOQESM, held on October 11-12, 2016, Brest, France, this book includes carefully revised and extended chapters presented at the conference, together with original papers not related to the event. All in all, it provides readers with a snapshot of current methods for sonar track registration, multi-vehicles control, collective exploration of underwater environments, optimization of propulsion systems, among others. More than that, the book is aimed as source of inspiration and tool to promote further discussions and collaboration between hydrographers, robotic specialists and other related communities.

Underwater Robots PDF Author: Gianluca Antonelli
Publisher: Springer
ISBN: 3319778994
Category : Technology & Engineering
Languages : en
Pages : 374

Book Description
A classic in underwater robotics. One of the first volumes in the “Springer Tracts in Advanced Robotics” series, it has been a bestseller through the previous three editions. Fifteen years after the publication of the first edition, the fourth edition comes to print. The book addresses the main control aspects in underwater manipulation tasks. With respect to the third edition, it has been revised, extended and some concepts better clustered. The mathematical model with significant impact on the control strategy is discussed. The problem of controlling a 6-degrees-of-freedoms autonomous underwater vehicle is investigated and a survey of fault detection/tolerant strategies for unmanned underwater vehicles is provided. Inverse kinematics, dynamic and interaction control for underwater vehicle-manipulator systems are then discussed. The code used to generate most of the numerical simulations is made available and briefly discussed.
