Abstract: Abstracts of thesis entitled Kinematics, Dynamics and Control of High Precision Parallel Manipulators Submitted by Cheung Wing Fung Jacob for the degree of Doctor of Philosophy at The University of Hong Kong in March 2007 End-point positioning accuracy, fast point-to-point motion travel and stable operation are essential in high-precision motion mechanisms for industrial applications such as semiconductor packaging. In this thesis, a high-precision 2-DOF planar parallel manipulator and a 4-DOF spatial parallel manipulator are developed to advance the motion capabilities of traditional XY table and overcome difficulties in the kinematics design and end-point positioning accuracy of existing parallel manipulators. Novel methods of kinematics design and optimization, dynamic modelling and advanced control strategies are integrated in a complete design of the proposed manipulators to achieve high-speed positioning of the end-effector to an accuracy of micrometer unit. Modular design approaches are developed for designing the kinematics structure of the proposed parallel manipulators. In this design process, consideration is given to ensuring that the kinematics design can be realized to the required tolerance using existing mechanical construction technology. A Monte-Carlo simulation method is developed to determine the workspace of the parallel manipulator, and a Jacobian decoupling approach is developed to verify that the workspace of the manipulator is free of internal singularity. Kinematics optimization is performed to suppress the kinematics error magnification effect so that the end-effector positioning accuracy matches the manufacturing tolerance of the linkages. A dynamic model is essential for motion analysis, capability estimation and controller design of the parallel manipulator. The derivation of the dynamic model is simplified using a nested approach whereby the 4-DOF parallel manipulator is decomposed into triangular mechanisms at the actuator level and at the end-effector level, resulting in a high degree of decoupling in the modelling process. Recursive Newton-Euler method is employed to determine the dynamic model. The response of the dynamic model is simulated using sinusoidal force profiles to drive the linear actuators of the manipulator. The results obtained from the kinematics design, optimization and dynamic modelling are used to develop prototypes of the planar and 4-DOF parallel manipulators for the purpose of experimentation. A traditional PID computed-torque controller is first designed for the 2-DOF planar and the 4-DOF parallel manipulators using a model-based approach. In view of the limitations of the computed-torque control method, a robust learning control method is developed to enhance the motion performance by minimizing the settling time and steady-state error of the parallel manipulators. A frequency-domain system identification approach is used to identify the high frequency dynamics of the manipulator. A robust control design method is employed to design a stable, fast tracking-response feedback controller with less sensitivity to high frequency disturbance, with the control parameters determined using genetic algorithm. A Fourier-series based iterative learning controller is added to the feedforward path of the controller to improve the settling time by reducing the dynamic tracking

Book excerpt: Parallel structures are more effective than serial ones for industrial automation applications that require high precision and stiffness, or a high load capacity relative to robot weight. Although many industrial applications have adopted parallel structures for their design, few textbooks introduce the analysis of such robots in terms of dynamics and control. Filling this gap, Parallel Robots: Mechanics and Control presents a systematic approach to analyze the kinematics, dynamics, and control of parallel robots. It brings together analysis and design tools for engineers and researchers who want to design and implement parallel structures in industry. Covers Kinematics, Dynamics, and Control in One Volume The book begins with the representation of motion of robots and the kinematic analysis of parallel manipulators. Moving beyond static positioning, it then examines a systematic approach to performing Jacobian analysis. A special feature of the book is its detailed coverage of the dynamics and control of parallel manipulators. The text examines dynamic analysis using the Newton-Euler method, the principle of virtual work, and the Lagrange formulations. Finally, the book elaborates on the control of parallel robots, considering both motion and force control. It introduces various model-free and model-based controllers and develops robust and adaptive control schemes. It also addresses redundancy resolution schemes in detail. Analysis and Design Tools to Help You Create Parallel Robots In each chapter, the author revisits the same case studies to show how the techniques may be applied. The case studies include a planar cable-driven parallel robot, part of a promising new generation of parallel structures that will allow for larger workspaces. The MATLAB® code used for analysis and simulation is available online. Combining the analysis of kinematics and dynamics with methods of designing controllers, this text offers a holistic introduction for anyone interested in designing and implementing parallel robots.

Download or read book Parallel Manipulators written by Jee-Hwan Ryu and published by BoD – Books on Demand. This book was released on 2008-04-01 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parallel manipulators are characterized as having closed-loop kinematic chains. Compared to serial manipulators, which have open-ended structure, parallel manipulators have many advantages in terms of accuracy, rigidity and ability to manipulate heavy loads. Therefore, they have been getting many attentions in astronomy to flight simulators and especially in machine-tool industries.The aim of this book is to provide an overview of the state-of-art, to present new ideas, original results and practical experiences in parallel manipulators. This book mainly introduces advanced kinematic and dynamic analysis methods and cutting edge control technologies for parallel manipulators. Even though this book only contains several samples of research activities on parallel manipulators, I believe this book can give an idea to the reader about what has been done in the field recently, and what kind of open problems are in this area.
Book Synopsis Parallel Manipulators by : Cecilia Norton
Download or read book Parallel Manipulators written by Cecilia Norton and published by Nova Science Publishers. This book was released on 2016 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robots are a key element in current industrial processes, as they can be applied to a number of tasks, increasing both quality and productivity. Traditionally, serial robots have been installed in factories, as their wide operating space allowed them to fulfill a number of tasks. However, due to their high moving mass and single kinematic chain structure, these robots present some disadvantages when high speed, accuracy or heavy load handling tasks have to be executed. Parallel robots provide an interesting alternative to these application fields, as their multiple kinematic chain structure offers increased stiffness, allowing reduced positioning errors, lighter mechanisms and increased load/weight ratios. In this book, Chapter One addresses a new control strategy for parallel manipulators based on L1 adaptive control. This latter is known for its decoupled control and estimation loops, enabling fast adaptation and guaranteed robustness. Chapter Two focuses on the control of parallel robots. Chapter Three reviews structure synthesis of fully-isotropic two-rotational and two-translational parallel robotic manipulators. Chapter Four reviews the new prototype of the two-legged, parallel kinematic walking robot CENTAUROB, developed at Hamburg University of Technology. Chapter Five analyzes and robustly controls the 6-DOF 3-legged Wide-Open parallel manipulator, using a Lyapunov analysis approach.

This book was released on 2008 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of parallel manipulator has received a lot of attention recently in the industry and the robotic community due to its high accuracy, high rigidity, high operation speed, high load capacity and high stiffness as compared with the conventional serial manipulator. One of the most popular parallel manipulators that are commonly used for aircraft simulator is the general purpose 6 degree-of-freedom (DOF) Stewart parallel manipulator. Despite these advantages, the kinematic and dynamic analyses are extremely complicated. Such models are important in terms of qualitative analysis of the required actuator forces to realize certain end-effector task (inverse dynamics), and computing the corresponding end-effector task based on certain input to the system (forward dynamics). However, till date, not much general symbolic solution is reported to aid the above process. Most of the prior work required some form of heuristic, or introduction of extra spring/damper elements to approximate the solutions. This thesis addresses the possibility in using the state-of-the-art symbolic manipulation software tool to derive the general kinematic and dynamic equation of motion of the system so that more accurate solution can be computed. However, there are still consideration are needed to accurately simulate such systems. We address these issues using the example of Stewart parallel manipulator and highlight the solution to the corresponding challenges. Control using stabilizing inverse dynamics was implemented to enhance trajectory tracking of the system.

Download or read book Control Dynamics of Robotic Manipulators written by J Skowronski and published by Elsevier. This book was released on 2012-12-02 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control Dynamics of Robotic Manipulators deals with both theory and mechanics of control and systems dynamics used in robotic movements. The book discusses mechanical models of robot manipulators in relation to modular RP-unit manipulators, multiple mechanical system (Cartesian Model), or generalized coordinates (Lagrangian Model). The text also describes equations used to determine the force characteristics, energy, and power required in manipulators. For example, damping forces dissipate energy caused by dry friction or viscous damping at mechanical joints due to slips and sheer effects on surfaces. Other examples are oil, water, and air resistance in the environment of the manipulator, as well as damping in links caused by microscopic interface effects. Demands for high-speed and high-accuracy in manipulators require sturdiness in control against variations in the system parameter. The book cites a situation where the manipulator works in a "hot cell" and must be controlled remotely. The text also tackles the avoidance of obstacles by nonvisual means by referring to the works of Lozano, Perez and Wesley, and of Reibert and Horn. The text is useful for students of civil, structural, and mechanical engineering. It will also profit technicians of automatic, telecontrol, and designers of industrial machinery.

Available in PDF, EPUB and Kindle. Book excerpt: The parallel robot, a kind of robot that utilizes multiple closed-loop branch chains jointly connecting and driving the moving platform, is an important part of modern robotics, with outstanding advantages of high stiffness, high precision and high speed. Parallel robots can efficiently change performance through the configuration of synthesis and design. The rich variety of configurations and the existence of a large number of passive joints also brought abundant challenges and research topics to the modeling, optimization, calibration and trajectory planning of parallel robots. This book focuses on the research frontiers of parallel robots from fundamental theory to application technology. Special attention is paid to kinematics/dynamics modeling, error modeling and calibration, impedance control and the machining stability of parallel robots. Notably, a considerable portion of the book focuses on cable-driven parallel robots (CDPRs) that integrate cable-driven kinematic chains and parallel mechanism theory. CDPRs inherit the high dynamics and heavy load capacities of parallel robots and significantly improve the workspace, cost and energy efficiency simultaneously, following the cutting-edge trend of rigid-flexible fusion.

Download or read book Dynamic Decoupling of Robot Manipulators written by Vigen Arakelian and published by Springer. This book was released on 2018-02-20 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest results in the field of dynamic decoupling of robot manipulators obtained in France, Russia, China and Austria. Manipulator dynamics can be highly coupled and nonlinear. The complicated dynamics result from varying inertia, interactions between the different joints, and nonlinear forces such as Coriolis and centrifugal forces. The dynamic decoupling of robot manipulators allows one to obtain a linear system, i.e. single-input and single output system with constant parameters. This simplifies the optimal control and accumulation of energy in manipulators. There are two ways to create the dynamically decoupled manipulators: via optimal mechanical design or control. This work emphasises mechatronic solutions. These will certainly improve the known design concepts permitting the dynamic decoupling of serial manipulators with a relatively small increase in total mass of the moving links taking into account the changing payload. For the first time such an approach has been applied on serial manipulators. Also of great interest is the dynamic decoupling control of parallel manipulators. Firstly, the dynamic model of redundant multi-axial vibration table with load has been established, and, secondly, its dynamic coupling characteristics have been analyzed. The discussed methods and applications of dynamic decoupling of robot manipulators are illustrated via CAD simulations and experimental tests.
