An autonomous sailboat robot is a boat that only uses the wind on
its sail as propelling force, without remote control or human
assistance to achieve its mission. This involves autonomy in energy
(using batteries, solar panels, turbines...), sensor data
processing (compass, GPS, wind sensor...), actuators control
(rudder and sail angle control...) and decision making (embedded
computer with adequate algorithms). Although robotic sailing is a
relatively new field of research, several applications exist for
this type of robots: oceanographic and hydrographic research,
maritime environment monitoring, meteorology, harbor safety,
assistance and rescue in dangerous areas...
Over the last decade, several events such as the Microtransat
challenge, the WRSC/IRSC and SailBot have been set up to stimulate
research and development around robotic sailing. These proceedings
cover the current and future academic and technology challenges
raised by the development of autonomous sailboat robots presented
at the WRSC/IRSC (World Robotic Sailing Championship/International
Robotic Sailing Conference) 2013, in Brest, France, 2-6 September
2013.
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.
This book is about guaranteed numerical methods based on interval analysis for approximating sets, and about the application of these methods to vast classes of engineering problems. Guaranteed means here that inner and outer approximations of the sets of interest are obtained, which can be made as precise as desired, at the cost of increasing the computational effort. It thus becomes possible to achieve tasks still thought by many to be out of the reach of numerical methods, such as finding all solutions of sets of non-linear equations and inequality or all global optimizers of possibly multi-modal criteria.The basic methodology is explained as simply as possible, in a concrete and readily applicable way, with a large number of figures and illustrative examples. Some of the techniques reported appear in book format for the first time. The ability of the approach advocated here to solve non-trivial engineering problems is demonstrated through examples drawn from the fields of parameter and state estimation, robust control and robotics. Enough detail is provided to allow readers with other applications in mind to grasp their significance. An in-depth treatment of implementation issues facilitates the understanding and use of freely available software that makes interval computation about as easy as computation with floating-point numbers. The reader is even given the basic information needed to build his or her own C++ interval library.The CD-ROM contains a trial version of Sun Microsystems' Forte(TM) Developer 6 for use with Solaris(TM) SPARC(TM) Platform Edition 2.6, 2.7 and 2.8.
This volume constitutes the results of the International Conference
on Underwater Environment, MOQESM'14, held at "Le Quartz"
Conference Center in Brest, France, on October 14-15, 2014, within
the framework of the 9th Sea Tech Week, International Marine
Science and Technology Event. The objective of MOQESM'14 was to
bring together researchers from both academia and industry,
interested in marine robotics and hydrography with application to
the coastal environment mapping and underwater infrastructures
surveys. The common thread of the conference is the combination of
technical control, perception, and localization, typically used in
robotics, with the methods of mapping and bathymetry. The papers
presented in this book focus on two main topics. Firstly, coastal
and infrastructure mapping is addressed, focusing not only on
hydrographic systems, but also on positioning systems, bathymetry,
and remote sensing. The proposed methods rely on acoustic sensors
such as side scan sonars, multibeam echo sounders, phase-measuring
bathymetric sonars, as well as optical systems such as underwater
laser scanners. Accurate underwater positioning is also addressed
in the case of the use of a single acoustic beacon, and the latest
advances in increasing the vertical precision of Global Navigation
Satellite System (GNSS) are also presented. Most of the above
mentioned works are closely related to autonomous marine vehicles.
Consequently, the second part of the book describes some works
concerning the methods associated with such type of vehicles. The
selected papers focus on autonomous surface or underwater vehicles,
detailing new approaches for localization, modeling, control,
mapping, obstacle detection and avoidance, surfacing, and software
development. Some of these works imply acoustics sensing as well as
image processing. Set membership methods are also used in some
papers. The applications of the work presented in this book concern
in particular oceanography, monitoring of oil and gas
infrastructures, and military field.

Mobile Robotics presents the different tools and methods that
enable the design of mobile robots; a discipline booming with the
emergence of flying drones, underwater robots mine detectors,
sailboats robots and robot vacuum cleaners. Illustrated with
simulations, exercises and examples, this book describes the
fundamentals of modeling robots, developing the actuator concepts,
sensor, control and guidance. Three-dimensional simulation tools
are also explored, as well as the theoretical basis for reliable
localization of robots within their environment.

At the core of many engineering problems is the solution of sets of
equa tions and inequalities, and the optimization of cost
functions. Unfortunately, except in special cases, such as when a
set of equations is linear in its un knowns or when a convex cost
function has to be minimized under convex constraints, the results
obtained by conventional numerical methods are only local and
cannot be guaranteed. This means, for example, that the actual
global minimum of a cost function may not be reached, or that some
global minimizers of this cost function may escape detection. By
contrast, interval analysis makes it possible to obtain guaranteed
approximations of the set of all the actual solutions of the
problem being considered. This, together with the lack of books
presenting interval techniques in such a way that they could become
part of any engineering numerical tool kit, motivated the writing
of this book. The adventure started in 1991 with the preparation by
Luc Jaulin of his PhD thesis, under Eric Walter's supervision. It
continued with their joint supervision of Olivier Didrit's and
Michel Kieffer's PhD theses. More than two years ago, when we
presented our book project to Springer, we naively thought that
redaction would be a simple matter, given what had already been
achieved . . ."
