Повний текст джерелаOs veículos aéreos não tripulados são cada vez mais procurados para desempenhar diversas tarefas do quotidiano. Estes sistemas são, no entanto, caros e necessitam de equipas grandes para serem operados. O controlo de veículos aéreos autónomos num ambiente parcialmente conhecido é uma tarefa complexa. Os sistemas actuais são baseados em sensores e sistemas de controlo relativamente dispendiosos, e são frequentemente pesados, necessitando de uma grande quantidade de energia. O principal objectivo deste projecto é desenvolver um sistema aéreo não tripulado, fácil de operar, para inspecção e monitorização. Integrados neste sistema encontram-se a plataforma do robô aéreo, o sistema de controlo e a estação de controlo remoto. A plataforma desenvolvida é baseada em veículos mais leves que o ar. Pretende-se que esta plataforma seja capaz de navegar por espaços confinados e também em ambientes fechados. A esta plataforma foram incorporados sensores e sistemas de controlo leves e de baixo consumo de energia. Para a estação de supervisão foi desenvolvido um programa que permite o controlo do robô e supervisão dos objectivos da missão. A interface gráfica permite de uma forma intuitiva efectuar o controlo do robô. Os testes iniciais permitiram demonstrar as capacidades dos sistemas desenvolvidos para atingir os objectivos propostos. ABSTRACT: Unmanned aerial vehicles are being increasingly sought to perform every days tasks. But these systems are still costly and require a large crew of mission controllers and pilots to adequately manoeuvre the UAV. Managing and control an autonomous air vehicle in a partially known and uncontrolled environment is a complex problem. Current UAVs are based on costly sensors and control systems. These control systems are also usually heavy and demand large amounts of power. This thesis aims to develop an easy to operate unmanned aerial system for surveillance and monitoring missions. As part of this system will be developed an aerial platform, the embedded control system, the ground station with a graphical interface. The platform designed is based on a small lighter-than-air vehicle. To successfully complete the mission objectives the UAV must be capable of navigate through constrained areas and endow indoor flights. The UAV is equipped with low power consumption sensors and processors. For the ground station will be developed an application to control and monitor the UAV status. The graphical user interface application provide an easy to use interface to control and monitor the mission objectives. The initial tests allowed to validate the feasibility of the systems developed to achieve the proposed goals.

This thesis describes the design and testing of a quadcopter that capable of both driving and flying. This was achieved by mounting quadcopter motors and propellers to the center of each of the robot's four wheels. The wheels are then capable of changing orientation in order to allow the robot to either drive or fly. Each of these wheels contains a gearing and bearing system that decouples the rotation of the wheels from the rotation of the propellers and also houses the system's landing gear. The prototype described in this thesis is capable of driving on flat surfaces as well as vertical take-off and landing. Further improvements to the system would be required in order for it to perform longer flights, complex aerial maneuvers, drive on uneven surfaces, or carry additional payloads.

Commercially available Unmanned Aerial Vehicles (UAVs), especially multi-rotor aircrafts, have a flight time of less than 30 minutes. However many UAV applications, such as surveillance, package delivery, and infrastructure monitoring, require much longer flight times. To address this problem, we present a system in which an Unmanned Ground Vehicle (UGV) can recharge the UAV during deployments. This thesis studies the problem of finding when, where, and how much to recharge the battery. We also allow for the UGV to recharge while moving from one site to another. We present an algorithm that finds the paths for the UAV and UGV to visit a set of points of interest in the least time possible. We also present algorithms for cases when the UGV is slower than the UAV, and more than one UGV may be required. We evaluate our algorithms through simulations and proof-of-concept experiments.

Повний текст джерелаThe role of unmanned aerial vehicles (UAVs) in military, commercial and recreational applications is continuously evolving as devel-opments in technology increase capabilities. The research herein presents an inexpensive computer-vision-based solution for detection and classification of a stationary target with a mobile aerial sensor as a prototyping platform. The main goal of this system is to use commercial-off-the-shelf and open-source components to reduce design complexity to provide a legacy product for future develop-ment of specific capabilities. Color imagery collected during flight using a low-resolution camera is used to test the application of a simple algorithm against a commercially available and low cost sensor. Original image processing algorithms that leverage the existing body of works in the open-source community are developed and tested within the Systems Engineering construct. System architec-ture leverages a modular approach that can be easily modified and adapted to changing requirements and objectives. Conclusions are drawn and recommendations for further study and system development are presented.

Повний текст джерела[spa]El transporte marítimo es una de las maneras más efectivas de transportar mercancías de un lugar a otro del mundo. Aunque hoy en día se llevan a cabo muchos esfuerzos para evitar los accidentes marítimos, estos todavía ocurren y, de vez en cuando, tienen consecuencias catastróficas en términos ambientales, humanos y/o económicos. Los daños estructurales causados por grietas y/o corrosión son la causa principal de estos accidentes y, por ello, los barcos son sometidos a inspecciones periódicas con el objetivo de garantizar su integridad estructural. Para llevar a cabo una inspección, los barcos son vaciados y llevados a un astillero donde se instalan andamiajes para permitir a los inspectores alcanzar las zonas más altas de su estructura. Estas inspecciones se realizan muchas veces en entornos peligrosos o de difícil acceso. En términos económicos, el proceso puede suponer un desembolso de hasta un millón de dolares. Por todo ello, cualquier contribución que suponga una reducción en el tiempo/coste de la inspección, o un incremento en la seguridad de los operarios, está justificada. En esta tesis se proponen nuevas herramientas tecnológicas que pretenden contribuir al rediseño de los procesos de inspección visual de barcos. Por un lado, se propone una nueva plataforma robótica aérea que permite al operario realizar la inspección del barco desde una posición segura y cómoda. Esta plataforma consiste en un dispositivo de fácil manejo que ha sido desarrollado siguiendo el paradigma de la Autonomía Supervisada, de tal manera que el vehículo se encarga de todas las tareas referentes a la seguridad, mientras que el operario proporciona las consignas de desplazamiento y puede centrarse en el proceso de inspección. Por otro lado, se proponen diversos algoritmos basados en visión para la detección de defectos en la estructura del barco. En primer lugar, se proponen varios métodos para la detección de corrosión, basados en la combinación de diferentes descriptores de color y de textura. En segundo lugar, se propone un algoritmo para la detección de grietas que combina la extracción de contornos con un proceso de crecimiento de regiones. Finalmente, se evalúa el concepto de notoriedad para la detección de defectos genéricos, y para la mejora del rendimiento de los detectores de corrosión y de grietas. La plataforma robótica y los detectores de defectos propuestos han sido evaluados tanto en laboratorio como durante pruebas de campo realizadas a bordo de un barco real. Los resultados obtenidos permiten confirmar la utilidad y el buen rendimiento de las diferentes herramientas tecnológicas propuestas.
[eng]Vessels are nowadays one of the most cost effective ways to transport goods around the world. Despite the efforts to avoid maritime accidents, these still occur and, from time to time, have catastrophic consequences in environmental, human and/or economic terms. Structural failures caused by cracks and/or corrosion are the main cause of these accidents and, as such, vessels are submitted to periodical inspections in order to ensure their structural integrity. To carry out this task, vessels have to be emptied and situated in a dockyard where high scaffoldings are installed to allow the human inspectors to reach the highest parts of the vessel structure. Besides, the surveys are on many occasions performed in hazardous environments with difficult access. In economic terms, total expenses can reach up to one million dollars. Therefore, it is clear that any level of automation of the inspection process that can lead to a reduction of the inspection time, a reduction of the financial costs and/or an increase in the safety of the operation is fully justified. In this regard, this dissertation presents novel technological tools to contribute to re-engineering the process of vessel visual inspection. On the one hand, a novel aerial robotic platform is proposed to allow the surveyor to perform a proper inspection from a safe and comfortable position. It consists in an easy-to-use device which has been developed around the Supervised Autonomy paradigm, so that the vehicle is in charge of all the safety-related issues, while the surveyor provides the displacement commands and focuses on the inspection process. On the other hand, novel vision-based algorithms for defect detection on vessels structures are proposed. Firstly, several corrosion detection methods are described, based on the combination of different colour and texture descriptors. Secondly, a crack detection method, which combines edge detection with a region growing procedure, is proposed. Finally, the idea of saliency for detecting generic defects on vessel structures is evaluated, and also to improve the performance of the corrosion and crack detectors. The aerial platform and the defect detectors are evaluated both under laboratory conditions and during field tests performed on board real vessels. The results obtained allow to confirm the usability and the good performance of all the proposed technological tools.

Повний текст джерелаWildfires, also known as forest or wildland fires, are uncontrolled vegetation fires occurring in rural areas that cause tremendous damage to the society, harming environment, property and people. The firefighting endeavor is a dull, dirty and dangerous job and as such, can greatly benefit from automation to reduce human exposure to hazards. Aerial remote sensing is a common technique to obtain precise information about a wildfire state so fire response teams can prepare countermeasures. This task, when performed with manned aerial vehicles, expose operators to high risks that can be eliminated by the use of autonomous vehicles. This thesis introduces a wildfire monitoring system based on fleets of unmanned aerial vehicles (UAVs) to provide firefighters with timely updated information about a wildland fire. We present an approach to plan trajectories for a fleet of fixed-wing UAVs to observe a wildfire evolving over time. Realistic models of the terrain, of the fire propagation process, and of the UAVs are exploited, together with a model of the wind, to predict wildfire spread and plan UAV motion. The approach tailors a generic Variable Neighborhood Search method to these models and the associated constraints. The execution of the planned monitoring mission provides wildfire maps that are transmitted to the fire response team and exploited by the planning algorithm to plan new observation trajectories. Algorithms and models are integrated within a software architecture allowing for execution under scenarios with different levels of realism, with real and simulated UAVs flying over a real or synthetic wildfire. Mixed-reality simulation results show the ability to plan observation trajectories for a small fleet of UAVs, and to update the plans when new information on the fire are incorporated in the fire model

Повний текст джерелаObemannad luftfarkoster (UAV:er) kan navigera i inomhusmiljöer och genom miljöer som är farliga eller svåra att nå för människor. Detta gör dem lämpliga för användning i sök- och räddningsuppdrag och av akutmottagning och rättsväsende genom ökad situationsmedvetenhet. Dock är det även för en erfaren UAV-teleoperatör krävande och svårt att kontrollera en UAV i dessa situationer utan att kollidera med hinder. Denna avhandling presenterar ett människa-UAV-gränssnitt tillsammans med en kollisionsundvikande metod, båda optimerade för en mänsklig teleoperatör. Målet är att förenkla uppgiften att navigera en UAV i inomhusmiljöer. Utvärdering av systemet görs genom att testa det mot ett antal användningsfall och en användarstudie. Resultatet av denna avhandling är en kollisionsundvikande metod som lyckas skydda UAV från hinder och samtidigt tar hänsyn till operatörens avsikter.

Повний текст джерелаThe aim of this Thesis is to give contributions to the state of the art on the collective behavior of a group of flying robots, specifically quadrotor UAVs, which can only rely on their onboard capabilities and not on a centralized system (e.g., Vicon or GPS) in order to safely navigate in the environment. We achieve this goal by giving a possible solution to the problems of formation control and localization from onboard sensing and local communication. We tackle these problems exploiting mainly concepts from algebraic graph theory and the so-called theory of rigidity. This allows us to solve these problems in a decentralized fashion, and propose decentralized algorithms able to also take into account some typical sensory limitations. The onboard capabilities we referred to above are represented by an onboard monocular camera and an inertial measurement unit (IMU) in addition to the capability of each robot to communicate (through RF) with some of its neighbors. This is due to the fact that an IMU and a camera represent a possible minimal, lightweight and inexpensive configuration for the autonomous localization and navigation of a quadrotor UAV

Повний текст джерелаHierarchical Task Network (HTN) planning is a popular approach to build task plans to control intelligent systems. This thesis presents the HATP (Hierarchical Agent-based Task Planner) planning framework which extends the traditional HTN planning domain representation and semantics by making them more suitable for roboticists, and by offering human-awareness capabilities. When computing human-aware robot plans, it appears that the problems are very complex and highly intricate. To deal with this complexity we have integrated a geometric planner to reason about the actual impact of actions on the environment and allow to take into account the affordances (reachability, visibility). This thesis presents in detail this integration between two heterogeneous planning layers and explores how they can be combined to solve new classes of robotic planning problems

Drones or Unmanned Aerial Manipulators have been used in the construction industry to collect visual data in form of images, videos, or to map surveys, and visually inspect the structures. However, if equipped with a robotic arm, they attain the capability of touching and interacting with the environment to effectively function as an Unmanned Aerial Manipulator (UAM). UAMs have researched for various applications such as sensor installation, touch-based sensor inspections, door opening, and closing, and pick up and drop, etc. However, there is a lack of study for their opportunities and challenges in the construction industry. This research focuses on understanding the opportunities and challenges associated with the application of UAMs in the construction industry.

Повний текст джерелаThe biorobotics team from the Institute of Movement Sciences (Marseille, France) takes its inspiration from biological studies on flying insects which are able to navigate into unknown 3D environments with a high maneuverability. These studies led us to build minimalist optical sensors to make aerial robots autonomous for achieving complex tasks such as automatic landing and take-off, obstacle avoidance and very accurate hovering flight depicted in this doctoral thesis. This work presents several bio-inspired visual sensors implemented with different visual processing algorithms. All these sensors are able to locate visual objects (contrasting edges and bars) with unusual properties for optical sensing devices: a blur obtained by defocusing optics related with active retinal micro-movements to improve the sensor resolution. We showed that the resolution in locating contrasting objects can be improved up to 160 fold better than the static resolution defined by the pixel pitch, which means that these bio-inspired optical sensors are endowed with hyperacuity.The thesis presents a miniature artificial compound eye CurvACE (of 1.75g for 2.2cm3) with a panoramic field of view (180x60°). This thesis describes thoroughly the characterization and the implementation of the CurvACE sensor onboard an aerial robot named HyperRob. This artificial compound eye acts as a position sensing device able to measure its position relative to a complex textured scene by fusing the position measurements obtained by 40 pixels. The tethered flying robot HyperRob (a 150-g bi-rotor with a 23-cm wingspan) stabilizes its roll and its position thanks to its hyperacute artificial compound eye

Повний текст джерелаWhat are the common characteristics of humanoid robots and quadrotors? Well, not many… Therefore, this thesis focuses on the development of algorithms allowing to dynamically control a robot while staying generic with respect to the model of the robot and the task that needs to be solved. Numerical optimal control is good candidate to achieve such objective. However, it suffers from several difficulties such as a high number of parameters to tune and a relatively important computation time. This document presents several ameliorations allowing to reduce these problems. On one hand, the tasks can be ordered according to a hierarchy and solved with an appropriate algorithm to lower the number of parameters to tune. On the other hand, machine learning can be used to initialize the optimization solver or to generate a simplified model of the robot, and therefore can be used to decrease the computation time

Повний текст джерелаThis research work addresses the problems of attitude estimation of rigid bodies moving in 3D-space with an acceleration which is neither constant, nor negligible as compared to the gravity, using IMU and GPS. We propose an observer based on proportional-integral type second order sliding mode to estimate unknown bounded time-varying input to a nonlinear dynamical system. Exponential convergence on the observed is demonstrated using Lyapunov theory in a general case. This observer has been applied to estimate the unknown linear acceleration in the inertial frame from the equations of rigid bodies translational dynamics. We then propose a two-step observer for which the estimation of linear acceleration is the first step which is then used in the equations of rigid bodies rotational dynamics at second step. The exponentially convergence at first step is sufficient excuse to study the convergence analysis of the rigid bodies rotational dynamics separately. The combined system is found to be almost global asymptotic convergent by using separation principle. We also propose a complementary filter to filter raw measurements of two non-collinear vectors in the body frame, for which we get global asymptotic convergence. Note that we get global exponential convergence if gyro-bias is not considered. After filtering these directions, the doors of attitude estimation through using some algebraic algorithm, are open. The performance of the proposed observers is illustrated by simulation results as well

Повний текст джерелаThis thesis addresses the study of autonomous Aerial Vehicles (AVs) actively interacting with the surrounding environment, with particular attention to the development of modeling and design techniques, and suitable control strategies for these systems. Due to the intrinsic difficulty and the novelty associated with the study of these systems, new techniques are needed to: i) better describe the aerial vehicle dynamics and its actuation limits; ii) effectively design new aerial prototypes with particular properties of dexterity and resilience; iii) guarantee a stable control during contact-less operations despite the actuation limits; and iv) preserve the system stability also during the contact phase with the environment while guaranteeing the fulfillment of the sought manipulation task. This thesis explores new strategies to overcome, to a certain extent, the under-actuation problem of classical multi-rotor platforms, conceived with the propellers aligned towards a common direction. The goal of this thesis is to contribute to a wise growth of the preliminary theoretical results on multi-directional thrust aerial vehicles laid by the state of the art and, furthermore, to the development of more suitable real aerial robotic systems with enhanced manipulation means, tailored for aerial physical interaction tasks. This thesis takes place inside the context of the European H2020 AeroArms project, whose goal is to develop aerial robotic systems with advanced manipulation capabilities to be applied in industrial inspection and maintenance. Hence, also the technology transfer and the impact on the industry plays here an important role

Повний текст джерелаIn recent years, the subject of physical interaction for aerial robots has been a popular research area with many new mechanical designs and control approaches being proposed. The aerial robotics community is currently observing a paradigm shift from classic guidance, navigation, and control tasks towards more unusual tasks, for example requesting aerial robots to physically interact with the environment, thus extending the manipulation task from the ground into the air. This thesis contributes to the field of aerial manipulation by proposing a novel concept known has Multiple Aerial-Ground Manipulator System or MAGMaS, including what appears to be the first experimental demonstration of a MAGMaS and opening a new route of research. The motivation behind associating ground and aerial robots for cooperative manipulation is to leverage their respective particularities, ground robots bring strength while aerial robots widen the workspace of the system. The first contribution of this work introduces a meticulous system model for MAGMaS. The system model's properties and potential extensions are discussed in this work. The planning, estimation and control methods which are necessary to exploit MAGMaS in a cooperative manipulation tasks are derived. This works proposes an optimal control allocation scheme to exploit the MAGMaS redundancies and a general model-based force estimation method is presented. All of the proposed techniques reported in this thesis are integrated in a global architecture used for simulations and experimental validation. This architecture is extended by the addition of a tele-presence framework to allow remote operations of MAGMaS. The global architecture is validated by robust demonstrations of bar lifting, an application that gives an outlook of the prospective use of the proposed concept of MAGMaS. Another contribution in the development of MAGMaS consists of an exploratory study on the flexibility of manipulated loads. A vibration model is derived and exploited to showcase vibration properties in terms of control. The last contribution of this thesis consists of an exploratory study on the use of elastic joints in aerial robots, endowing these systems with mechanical compliance and energy storage capabilities. Theoretical groundings are associated with a nonlinear controller synthesis. The proposed approach is validated by experimental work which relies on the integration of a lightweight variable stiffness actuator on an aerial robot
Tognon, Marco. "Theory and Applications for Control and Motion Planning of Aerial Robots in Physical Interaction with particular focus on Tethered Aerial Vehicles." Thesis, Toulouse, INSA, 2018. http://www.theses.fr/2018ISAT0030.
Повний текст джерелаThis thesis focuses on the study of autonomous aerial robots interacting with the surrounding environment, and in particular on the design of new control and motion planning methods for such systems. Nowadays, autonomous aerial vehicles are extensively employed in many fields of application but mostly as autonomously moving sensors. On the other hand, in the recent field of aerial physical interaction, the goal is to go beyond sensing-only applications and fully exploit the aerial robots capabilities in order to interact with the environment. With the aim of achieving this goal, this thesis considers the analysis of a particular class of aerial robots interacting with the environment: tethered aerial vehicles. This work focuses on the thorough formal analysis of tethered aerial vehicles ranging from control and state estimation to motion planning. In particular, the differential flatness property of the system is investigated, finding two possible flat outputs that reveal new capabilities of such system for the physical interaction. The theoretical results were finally employed to solve the challenging problem of landing and takeoff on/from a sloped surface. In addition, moved by the interest on aerial physical interaction from A to Z, we addressed supplementary problems related to the design, control and motion planning for aerial manipulators

Повний текст джерелаThe new goal for unmanned aerial systems will be to find creative methods of keeping the cost low and still maintain effectiveness. This thesis discusses the importance of UAVs over the last few years, suggests the development of a low-cost, large UAV, and evaluates the results. We also examine the idea of a platform for deploying multiple aerial-delivery, parafoil-based systems and discuss scenarios for the improvement of the collaboration of the large UAV with the Snowflake project.

Повний текст джерелаRobotik revolutionerar arbetet i farliga miljöer som gruvor och tunnlar, vilket gör livet enklare och säkrare för arbetarna. Det specifika fallet som behandlas i denna avhandling gäller UAV: er som används för 3D-kartläggning av dessa zoner. Användningen av UAV i underjordiska gruvor kan dock vara utmanan- de av många anledningar, till exempel minskad sikt, ingen GPS-lokalisering tillgänglig och begränsad trådlös kommunikation, utmaningar som delvis kan lösas genom att göra roboten autonom. Just av dessa skäl syftar detta arbe- te till att bidra till denna applikation med implementeringen av en autonom vägplaneringsalgoritm för flygfordon i underjordiska zoner. Det relaterade ar- betet har utvecklats med stöd av Inkonova AB, ett robotföretag i Stockholm. Emellertid gäller det speciella bidraget till detta arbete axelminor, som är ver- tikala eller nästan vertikala tunnlar med åtkomst från toppen och botten. Det- ta speciella scenario är extremt utmanande för UAV: er, eftersom längden på dessa tunnlar (vanligtvis 100-200 m) orsakar förlorad signal från kontroll- stationen under uppdraget. Därför väljs den implementerade algoritmen för att lyckas i axelscenarier. Sedan har en optimering av algoritmen gjorts för att minska uppdragstiden och därmed öka chanserna för framgång genom att spara i robotens batteri.

Повний текст джерелаRoboternas förmåga att arbeta i farliga miljöer som underjordiska gruvor kan göra det möjligt för arbetare att arbeta i en säkrare miljö. I synnerhet kan kartläggning och utforska gruvor och tunnlar spara liv och pengar. För denna typ av uppdrag väljs ofta UAV: er tack vare deras höga rörlighet i 3D-utrymmen. Men för att göra det måste roboten arbeta i en komplex miljö med nedsatt synlighet och dåliga anslutningar. Artificiell intelligens och särskilt Deep Reinforcement Learning (DRL) blir ett mer populärt tillvägagångssätt för att lösa denna typ av problem, men implementeringen av denna teknik är fortfarande svår och begränsad, särskilt vid behandling med 3D-data. Av dessa skäl är syftet med detta arbete att tillhandahålla ett nytt tillvägagångssätt för att lösa problemet med autonom utforskning av 3D-underjordiska miljöer med hjälp av DRL. Vi presenterar och förklarar de metoder som har fungerat och varför andra metoder inte har, med särskild uppmärksamhet i de resurser som används. Dessutom implementerar vi den nya tekniken med uppmärksamhet åt att tillhandahålla ett system som enkelt kan överföras i en riktig UAV. Därför testar vi det nya tillvägagångssättet med det faktiska tillståndet i fältet och förklarar vilken teknik som används idag och varför DRL är ett värdefullt alternativ till mer analytiska tillvägagångssätt som används idag.

Повний текст джерелаAerial manipulation is one of the challenges of robotics over the last decade. One of the constraints on the development of aerial manipulators is the limited autonomy of drones, reduced by the load and energy consumption of the on-board manipulator. One way to overcome this limit is to have several drones collaborate on a manipulation task. This thesis deals with the design and control of a new type of autonomous aerial vehicle for manipulation tasks. The concept consists in the collaboration of several drones, in particular quadrotors, through a polyarticulated passive architecture. The robot thus obtained is a fusion between the passive architecture of a parallel robot and several drones. The study of the dynamic model of this robot class highlights a decoupling in the dynamic model. This decoupling allows the design of a cascade control law. This controller provides stabilization and trajectory tracking for these robots. Two study cases are then presented in this thesis: a flying parallel robot with two drones and a flying parallel robot with three drones. For these two robots, a numerical simulation is performed to validate the controller performances. These simulations also allowed to validate the reconfiguration abilities of passive architecture in flight. The work was successfully carried to the experimental stage for the flying robot with two drones
