This book addresses the design of compliant mechanisms, presenting readers with a good understanding of both the solid mechanics of flexible elements and their configuration design, based on a mechanism-equivalent approach in the framework of screw theory. The book begins with the theoretical background of screw theory, and systematically addresses both the compliance characteristics of flexible elements and their configuration design. The book then covers a broad range of compliant parallel mechanism design topics, from stiffness to constraint decomposition, from conceptual design to dimensional design, and from analysis to synthesis, as well as the large deformation problem; this is followed by both simulations and physical experiments, offering readers a solid foundation and useful tools. Given its scope and the results it presents, the book will certainly benefit and inform future research on the topic. It offers a valuable asset for researchers, developers, engineers and graduate students with an interest in compliant mechanisms, robotics and screw theory.

Firstly, the synthesis design problems of compliant parallel mechanisms are explored at both the conceptual-design level and dimensional-design level. At the conceptual-design level where mainly degrees of freedom and constraints are considered, screw theory is implemented to generate the arrangement of constraint flexible elements as well as actuators for given motions of a compliant parallel mechanism. At the dimensional-design level where the stiffness of compliant parallel mechanisms are considered, algorithms are developed that are able to decompose the pre-determined stiffness matrix of a compliant parallel mechanism into a combination of flexible elements, thus achieving complete synthesis without knowing the original layout of the compliant parallel mechanism. Then the optimization design of compliant parallel mechanisms is investigated following the stiffness synthesis. Ortho-planar springs are selected as examples, and their six-dimensional compliance performances are evaluated in forms of compliance matrices and optimized by conducting parameterization and optimization analysis of the design parameters. Finally this thesis investigates the large deformation problem of compliant parallel mechanisms using origami-inspired compliant mechanisms. Experimental tests are conducted to explore the stiffness behaviours of crease-type flexures, based on which a novel repelling-screw based analytical approach is proposed to analyze the force transmission of compliant origami structures undertaking large deformations. This also leads to the developments of a series of bio-inspired continuum robots and manipulators.

This book contains mechanism analysis and synthesis. In mechanism analysis, a mobility methodology is first systematically presented. This methodology, based on the author's screw theory, proposed in 1997, of which the generality and validity was only proved recently, is a very complex issue, researched by various scientists over the last 150 years. The principle of kinematic influence coefficient and its latest developments are described. This principle is suitable for kinematic analysis of various 6-DOF and lower-mobility parallel manipulators. The singularities are classified by a new point of view, and progress in position-singularity and orientation-singularity is stated. In addition, the concept of over-determinate input is proposed and a new method of force analysis based on screw theory is presented. In mechanism synthesis, the synthesis for spatial parallel mechanisms is discussed, and the synthesis method of difficult 4-DOF and 5-DOF symmetric mechanisms, which was first put forward by the author in 2002, is introduced in detail. Besides, the three-order screw system and its space distribution of the kinematic screws for infinite possible motions of lower mobility mechanisms are both analyzed.

Parallel Kinematics- Type, Kinematics, and Optimal Design presents the results of 15 year's research on parallel mechanisms and parallel kinematics machines. This book covers the systematic classification of parallel mechanisms (PMs) as well as providing a large number of mechanical architectures of PMs available for use in practical applications. It focuses on the kinematic design of parallel robots. One successful application of parallel mechanisms in the field of machine tools, which is also called parallel kinematics machines, has been the emerging trend in advanced machine tools. The book describes not only the main aspects and important topics in parallel kinematics, but also references novel concepts and approaches, i.e. type synthesis based on evolution, performance evaluation and optimization based on screw theory, singularity model taking into account motion and force transmissibility, and others. This book is intended for researchers, scientists, engineers and postgraduates or above with interests in robotics and advanced machine tools technology such as parallel kinematics machines (PKMs).

This book reviews the fundamentals of screw theory concerned with velocity analysis of rigid-bodies, confirmed with detailed and explicit proofs. The author additionally investigates acceleration, jerk, and hyper-jerk analyses of rigid-bodies following the trend of the velocity analysis. With the material provided in this book, readers can extend the theory of screws into the kinematics of optional order of rigid-bodies. Illustrative examples and exercises to reinforce learning are provided. Of particular note, the kinematics of emblematic parallel manipulators, such as the Delta robot as well as the original Gough and Stewart platforms are revisited applying, in addition to the theory of screws, new methods devoted to simplify the corresponding forward-displacement analysis, a challenging task for most parallel manipulators.

"Uncertainties are an inherent element of the manufacturing and control of mechanisms. Generally, uncertainties are neglected in the analysis and synthesis of mechanisms, as they can be difficult to account for. However, the performance of real mechanisms depends on the uncertainties; thus, there is a need for reliable methods which are able to provide bounds on the true performance of mechanisms. Parallel mechanisms are considered in this work, where the design of a parallel mechanism accounting for uncertainties is termed an appropriate design. Reliable methods, based on interval analysis, are developed to analyze and synthesize appropriately designed parallel mechanisms, fittingly termed appropriate analysis and appropriate synthesis respectively. These appropriate methods are applied to the four-bar linkage and the 3-R̲RR planar parallel mechanism. Appropriate analysis methods compute the associated workspaces of mechanisms with an appropriate design. These workspaces consider the reachability, self-collisions, singularities, and wrench-capabilities of the mechanisms, and are used to guarantee whether the desired task is able to be accomplished by the mechanism. Appropriate synthesis methods are able to completely explore a continuous design parameter space to determine the complete set of appropriate designs of a mechanism which accomplish the desired task. Any design selected from this set is guaranteed to accomplish the desired task. The development of appropriate analysis and appropriate synthesis introduces a powerful new tool to mechanisms designers."--Pages ii-iii.
