Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This thesis presents the design, fabrication, capabilities, and analysis of a test-bed Micro Air Vehicle (MAV) used in developing a vision-based flight control algorithm. Vision-based controlled flight and its further developments are geared towards use on MAVs of the future. A test-bed airplane was designed from MAV concepts, and was large enough to accommodate the current commercial components available on the market. Two generations of the vision-based MAV were developed and tested. Each generation had 0.6 m wingspan and used a pusher configuration with a flexible wing concept. The second generation, however, had an improved fuselage and wing design, drive system, and a unique morphing mechanism. Both vehicles were tested and compared during numerous flight and wind tunnel tests. Effects of the morphing mechanism on the flexible wing were analyzed in the wind tunnel using the digital image correlation method.

This book was released on 2007-01 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This intriguing book breaks new ground on an emerging subject that has attracted considerable attention: the use of unmanned micro air vehicles (MAVs) to conduct special, limited duration missions. Significant advances in the miniaturization of electronics make it now possible to use vehicles of this type in a detection or surveillance role to carry visual, acoustic, chemical, or biological sensors. Interestingly, many of the advances in MAV technology can be traced directly to annual student competitions, begun in the late 1990s, that use relatively low cost model airplane equipment. The wide variety of configurations entered in these contests and their ongoing success has led to a serious interest in testing the performance of these vehicles for adaptation to practical applications. MAVs present aerodynamic issues unique to their size and the speeds at which they operate. Of particular concern is the aerodynamic efficiency of various fixed wing concepts. Very little information on the performance of low aspect ratio wing planforms existed for this flight regime until MAVs became of interest and the proliferation of fixed wing designs has since expanded. This book presents a brief history of unmanned air vehicles and offers elements of aerodynamics for low aspect ratio wings. Propulsion and the basic concepts for fixed wing MAV design are presented, as is a method for autopilot integration. Three different wing configurations are presented in a series of step-by-step case studies. The goal of the book is to assist both working professionals and students to design, build, and fly MAVs, and do so in a way that will advance the state of the art and lead to the development of even smalleraircraft.

Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous Localization and Mapping (SLAM) is a challenging research area in robotics. SLAM is used to estimate the location of a mobile platform and simultaneously build a map of its surrounding environment. The essence of the SLAM algorithm is creating a map of everything that the mobile robot senses using its onboard sensors while simultaneously localizing itself on the built map. SLAM is used in the various robotics applications. `Roomba' robot was the first SLAM based vacuum cleaner introduced by iRobot. SLAM is also used in various applications such as autonomous navigation of mining robots, space explorations rovers, toy robots, and self-driving cars. For path planning or collision avoidance, the robot uses its poses and mapped environment to perform the specified task. Real-time SLAM systems perform the required processing such as capturing sensor data and processing the captured data in a real time. With limited computational power, the best policies as well as algorithms are being developed to obtain correct robot poses and a map of the environment in real time. The main challenge in SLAM is to design real time application with onboard processing for applications like autonomous navigation wherein robot may need to operate at night or under low illumination conditions. This research aimed at development of monocular Visual SLAM for indoor environment. This chapter presents the literature review of the various visual SLAM algorithms. First section discusses theoretical background of visual SLAM. The feature-based and direct approaches are presented in second section. The third section describes different embedded platforms used followed by review of SLAM algorithms. Various evaluation metrics used and the bench marking datasets, applications, open challenges in visual SLAM are discussed. Chronology of SLAM The development of visual SLAM took place in three phases: namely SLAM problems, Visual SLAM and Visual SLAM with IMU integration to achieve as robustness shown in Figure 2-1. In, first stage focused various mathematical expressions presented to solve the SLAM problem. During second phase the attention of SLAM shifted to visual approaches. Various visual SLAM algorithms were presented with RGB-D cameras, and stereo cameras. Fundamental properties of Visual SLAM such as consistency and convergence were studied. Various SLAM methods were developed around the visual LAM. In third phase the robustness of visual SLAM algorithm is improved. The goal of this stage is to improve the reliability of visual SLAM for various real-life applications. This lead to the development of visual inertial SLAM methods. he second phase of SLAM development is called as golden phase, since most of the problems in SLAM were solved. In 2007, The biggest achievement is keyframe based PTAM (Parallel Tracking and Mapping) was proposed[12]. This approach allowed task parallelization, good utilization of global optimization, reduction in computation time and reduction in tracking drift error. Nowadays, PTAM's framework is used in almost every visual SLAM algorithm. The Visual SLAM became reliable with integration of global optimization, effective use of loop closing, keyframe and map point culling policies for memory management and computation time. The parallelization using multi-threading helped to achieve real time performance. Different hardware's like RGB-D and stereo cameras were integrated with vision-based SLAM algorithms. In third phase, main focus was on improving the robustness of visual SLAM. The combination of camera and IMU became an important research topic. In 2010's, the combination of camera and IMU was used to implement the visual inertial approach.

Download or read book Study of Micro-Sized Technology, Micro Air Vehicles, and Design of a Payload Carrying Flapping Wing Micro Air Vehicle written by and published by . This book was released on 2006 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been recent interest by the military to have platforms capable of operating close to a point of interest without being detected while providing critical surveillance. By providing information that is not readily available, these platforms could provide a useful tool for small unit commanders in potentially life-threatening situations. Highly maneuverable, slow-flying micro air vehicles could fly under canopies, through alleys, or indoors to provide such intelligence. This study consists of a survey of current micro-sized technologies and commercially available components. The findings are presented and used in the design process of a larger payload-carrying variant of the NPS flapping wing micro air vehicle. The intent is to develop a readily deployable, backpackable, slow-flying micro air vehicle that can be used by smaller-size ground units in theatre for urban reconnaissance.

Available in PDF, EPUB and Kindle. Book excerpt: The advance in robotics has boosted the application of autonomous vehicles to perform tedious and risky tasks or to be cost-effective substitutes for their - man counterparts. Based on their working environment, a rough classi cation of the autonomous vehicles would include unmanned aerial vehicles (UAVs), - manned ground vehicles (UGVs), autonomous underwater vehicles (AUVs), and autonomous surface vehicles (ASVs). UAVs, UGVs, AUVs, and ASVs are called UVs (unmanned vehicles) nowadays. In recent decades, the development of - manned autonomous vehicles have been of great interest, and different kinds of autonomous vehicles have been studied and developed all over the world. In part- ular, UAVs have many applications in emergency situations; humans often cannot come close to a dangerous natural disaster such as an earthquake, a ood, an active volcano, or a nuclear disaster. Since the development of the rst UAVs, research efforts have been focused on military applications. Recently, however, demand has arisen for UAVs such as aero-robotsand ying robotsthat can be used in emergency situations and in industrial applications. Among the wide variety of UAVs that have been developed, small-scale HUAVs (helicopter-based UAVs) have the ability to take off and land vertically as well as the ability to cruise in ight, but their most importantcapability is hovering. Hoveringat a point enables us to make more eff- tive observations of a target. Furthermore, small-scale HUAVs offer the advantages of low cost and easy operation.
Book Synopsis Improvements of a Flying-wing Micro-Air-Vehicle by Closing the Control-loop on Ground by : Irene Gallego Sanchez
Download or read book Improvements of a Flying-wing Micro-Air-Vehicle by Closing the Control-loop on Ground written by Irene Gallego Sanchez and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro Air Vehicles (MAVs) are a very small Unmanned Vehicles which provide interesting indoor implementations due to its reduced size. Therefore, onboard payload is very restricted, so GPS use is very limited too. The most common payload is video-network and it works independently of vehicle control system. In this context, the autopilot addition in a given MAV platform results in a significant changes that could raise the process and, in the worst case, could be too expensive because of the weight limitation. A proposed solution is to design an autopilot that close the control loop of the System "on ground" and links by the remote control channel. Consequently, the orders are sent from ground station as an emulation of the remote control. To close the control loop of the system would be necessary the telemetry acquisition and send it through audio channel from video-network onboard in the platform. In addition it would be necessary to process the images on ground station to know the attitude and relative position at real time. This is an only indoor solution which is the main MAV actuation environment. Finally, a quad-rotor platform gyro-stabilized as a power plant simplifies immensely the closing of the control loop (in the ground station) implementation since we can divide the MAV control in different subsystems. Such the autopilot is on ground, it does not contribute to raise the weight restrictions, so the MAV's thrust is not compromised. It will be implemented a height stabilization subsystem in a MAV.
Download or read book The DelFly written by G.C.H.E. de Croon and published by Springer. This book was released on 2015-11-26 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the "Delfly", a flapping wing robot designed at Delft University in The Netherlands. How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard. This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Explorer is the world's first flapping wing MAV that is able to fly completely autonomously in unknown environments. The DelFly project started in 2005 and ever since has served as inspiration, not only to many scientific flapping wing studies, but also the design of flapping wing toys. The combination of introductions to relevant fields, practical insights and scientific experiments from the DelFly project make this book a must-read for all flapping wing enthusiasts, be they students, researchers, or engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Technological progress in a number of areas to include aerodynamics, micro- electronics, sensors, micro-electromechanical systems (MEMS), micro-manufacturing, and more, is ushering in the possibility for the affordable development and acquisition of a new class of military systems known as micro-air vehicles (MAV) MAVs are a subset of uninhabited air vehicles (UAV) that are up two orders of magnitude smaller than the manned systems that permeate our contemporary life, Recent advances in miniaturization may make possible vehicles that can carry out important military missions that heretofore were beyond our reach or could only be attained at great risk or resource expenditure. These missions will be possible if MAVs can fulfill their potential to attain certain attributes to include: low cost, low weight, little to no logistical "footprint," mission versatility, range, endurance, stealth, and precision. A review of the literature in this area indicates that the military potential of this emerging field remains on the "technological push" side of the equation with little to no "requirements pull" from the user community. Accordingly, concepts of operations deriving from the war fighting community - particularly the United States Air Force (USAF) - are sparse. At a higher level, the potential of micro-air vehicles opens up new possibilities in the formulation of military strategies that require investigation. This paper provides an outline of the contemporary technological dimension of MAVs and contemplates how they might be used to enhance Air Force operations.

Download or read book Unmanned Aircraft Systems written by Reg Austin and published by John Wiley & Sons. This book was released on 2011-09-20 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned Aircraft Systems delivers a much needed introduction to UAV System technology, taking an integrated approach that avoids compartmentalising the subject. Arranged in four sections, parts 1-3 examine the way in which various engineering disciplines affect the design, development and deployment of UAS. The fourth section assesses the future challenges and opportunities of UAS. Technological innovation and increasingly diverse applications are two key drivers of the rapid expansion of UAS technology. The global defence budget for UAS procurement is expanding, and in the future the market for civilian UAVs is expected to outmatch that of the military. Agriculture, meteorology, conservation and border control are just a few of the diverse areas in which UAVs are making a significant impact; the author addresses all of these applications, looking at the roles and technology behind both fixed wing and rotorcraft UAVs. Leading aeronautical consultant Reg Austin co-founded the Bristol International Remotely Piloted Vehicle (RPV) conferences in 1979, which are now the longest-established UAS conferences worldwide. In addition, Austin has over 40 years' experience in the design and development of UAS. One of Austin's programmes, the "Sprite UAV System" has been deployed around the world and operated by day and night, in all weathers.
