Book Description
An aerial robot is a system capable of sustained flight with no direct human control and able to perform a specific task. A lighter than air robot is an aerial robot that relies on the static lift to balance its own weight. It can also be defined as a lighter than air unmanned aerial vehicle or an unmanned airship with sufficient autonomy. Lighter than air systems are particularly appealing since the energy to keep them airborne is small. They are increasingly considered for various tasks such as monitoring, surveillance, advertising, freight carrier, transportation. This book familiarizes readers with a hierarchical decoupled planning and control strategy that has been proven efficient through research. It is made up of a hierarchy of modules with well defined functions operating at a variety of rates, linked together from top to bottom. The outer loop, closed periodically, consists of a discrete search that produces a set of waypoints leading to the goal while avoiding obstacles and weighed regions. The second level smoothes this set so that the generated paths are feasible given the vehicle's velocity and accelerations limits. The third level generates flyable, timed trajectories and the last one is the tracking controller that attempts to minimize the error between the robot measured trajectory and the reference trajectory. This hierarchy is reflected in the structure and content of the book. Topics treated are: Modelling, Flight Planning, Trajectory Design and Control. Finally, some actual projects are described in the appendix. This volume will prove useful for researchers and practitioners working in Robotics and Automation, Aerospace Technology, Control and Artificial Intelligence.

Book Description
Engineered Biomimicry covers a broad range of research topics in the emerging discipline of biomimicry. Biologically inspired science and technology, using the principles of math and physics, has led to the development of products as ubiquitous as VelcroTM (modeled after the spiny hooks on plant seeds and fruits). Readers will learn to take ideas and concepts like this from nature, implement them in research, and understand and explain diverse phenomena and their related functions. From bioinspired computing and medical products to biomimetic applications like artificial muscles, MEMS, textiles and vision sensors, Engineered Biomimicry explores a wide range of technologies informed by living natural systems. Engineered Biomimicry helps physicists, engineers and material scientists seek solutions in nature to the most pressing technical problems of our times, while providing a solid understanding of the important role of biophysics. Some physical applications include adhesion superhydrophobicity and self-cleaning, structural coloration, photonic devices, biomaterials and composite materials, sensor systems, robotics and locomotion, and ultra-lightweight structures. - Explores biomimicry, a fast-growing, cross-disciplinary field in which researchers study biological activities in nature to make critical advancements in science and engineering - Introduces bioinspiration, biomimetics, and bioreplication, and provides biological background and practical applications for each - Cutting-edge topics include bio-inspired robotics, microflyers, surface modification and more

Book Description
This chapter describes recent developments in the area of manmade microflyers. The design space for microflyers is described, along with fundamental physical limits to miniaturizing mechanisms, energy storage, and electronics. Aspects of aerodynamics at the scale of microflyers are discussed. Microflyer concepts developed by a number of researchers are described in detail. Because the focus is on bioinspiration and biomimetics, scaled-down versions of conventional aircraft, such as fixed-wing micro air vehicles and micro-helicopters, are not addressed. Modeling of the aeromechanics of flapping wing microflyers is described with an illustrative example. Finally, some of the sensing mechanisms used by natural flyers are discussed.

Book Description
This book provides state-of-the-art scientific and engineering research findings and developments in the area of mobile robotics and associated support technologies. The book contains peer reviewed articles presented at the CLAWAR 2010 conference. Robots are no longer confined to industrial manufacturing environments. A great deal of interest is invested in the use of robots outside the factory environment. The CLAWAR conference series, established as a high profile international event, acts as a platform for dissemination of research and development findings and supports such a trend to address the current interest in mobile robotics to meet the needs of mankind in various sectors of the society. These include personal care, public health, and services in the domestic, public and industrial environments. The editors of the book have extensive research experience and publications in the area of robotics in general and in mobile robotics specifically, and their experience is reflected in editing the contents of the book.

Book Description
Lithium-sulfur (Li-S) batteries provide an alternative to lithium-ion (Li-ion) batteries and are showing promise for providing much higher energy densities. Systems utilizing Li-S batteries are presently under development and early stages of commercialization. This technology is being developed in order to provide higher, safer levels of energy at significantly lower costs. Lithium-Sulfur Batteries: Advances in High-Energy Density Batteries addresses various aspects of the current research in the field of sulfur cathodes and lithium metal anode including abundance, system voltage, and capacity. In addition, it provides insights into the basic challenges faced by the system. The book includes novel strategies to prevent polysulfide dissolution in sulfur-based systems while also exploring new materials systems as anodes preventing dendrite formation in Li metal anodes. - Provides insight into the basic challenges faced by the materials system - Discusses additives and suppressants to prevent dissolution of electrolyes - Includes a review of the safety limitations associated with this technology - Incorporates a historical perspective into the development of lithium-sulfur batteries
