Available in PDF, EPUB and Kindle. Book excerpt: Modular self-reconfigurable robots (MSRs) are composed of multiple modules which can change their connections with each other to take different shapes, commonly known as configurations. Forming different configurations helps the MSR to accomplish diferent types of tasks in different environments. In this dissertation, we study three different problems in MSRs: partitioning of modules, configuration formation planning and locomotion learning, and we propose algorithmic solutions to solve these problems. Partitioning of modules is a decision-making problems for MSRs where each module decides which partition is a NP-complete problem. We propose game theory based both centralized and distributed solutions to solve this problem. Once the modules know which set of modules they should team-up with, they self-aggregate to form a specific shaped configuration, known as the configuration forming planning problem. Modules can be either singletons or connected in smaller configurations from which they need to form the target configuration. The configuration formation problem is difficult as multiple modules may select the same location in the target configuration to move to which might result in occlusion and consequently failure of the configuration formation process. On the other hand, if the modules are already in connected configurations in the beginning, then it would be beneficial to preserve those initial configurations for placing them into the target configuration as disconnections and re-connections are costly operations, We propose solutions based on an auction-like algorithm and (sub) graph-isomorphism to solve the configuration problem. Once the configuration is built, the MSR needs to move towards its goal location as a whole configuration for completing its task. If the configuration's shape and size is not known a priori, then planning its locomotion is a difficult task as it needs to learn the locomotion pattern in dynamic time - the problem is known as adaptive locomotion learning. We have proposed reinforcement learning based on fault-tolerant solutions for locomotion learning by MSRs.

Book excerpt: A comprehensive survey of the growing field of self-reconfigurable robots that discusses the history of the field, design considerations, and control strategies. Self-reconfigurable robots are constructed of robotic modules that can be connected in many different ways. These modules move in relationship to each other, which allows the robot as a whole to change shape. This shapeshifting makes it possible for the robots to adapt and optimize their shapes for different tasks. Thus, a self-reconfigurable robot can first assume the shape of a rolling track to cover distance quickly, then the shape of a snake to explore a narrow space, and finally the shape of a hexapod to carry an artifact back to the starting point. The field of self-reconfigurable robots has seen significant progress over the last twenty years, and this book collects and synthesizes existing research previously only available in widely scattered individual papers, offering an accessible guide to the latest information on self-reconfigurable robots for researchers and students interested in the field. Self-Reconfigurable Robots focuses on conveying the intuition behind the design and control of self-reconfigurable robots rather than technical details. Suggestions for further reading refer readers to the underlying sources of technical information. The book includes descriptions of existing robots and a brief history of the field; discussion of module design considerations, including module geometry, connector design, and computing and communication infrastructure; an in-depth presentation of strategies for controlling self-reconfiguration and locomotion; and exploration of future research challenges.

Available in PDF, EPUB and Kindle. Book excerpt: What Is Self Reconfiguring Modular Robot Self-reconfigurable modular robots are autonomous kinematic machines that may take on a variety of shapes and configurations. They are also known as modular self-reconfiguring robotic systems. In addition to the conventional actuation, sensing, and control that are typically found in fixed-morphology robots, self-reconfiguring robots have the ability to deliberately change their own shape by rearranging the connectivity of their parts. This enables them to adapt to new circumstances, perform new tasks, or recover from damage more quickly than fixed-morphology robots.

Available in PDF, EPUB and Kindle. Book excerpt: Modular reconfigurable robots were intensively studied. In particular, problems of planning of self-reconfiguration received considerable attention. Problems of reconfiguration planning play a central role for modular reconfigurable robots. Solutions for such problems lies at the heart of any control system of modular reconfigurable robots. Performance of such solutions is the base factor for the performance of the whole control system of modular reconfigurable robot. Recently, the optimal reconfiguration planning problem of finding the least number of reconfiguration steps to transform between two configurations for chain-type modular robots was introduced. It is preferred that the robot keeps connected throughout the reconfiguration process. Respectively, in this book we suppose that the robot keeps connected throughout the reconfiguration process. We describe an approach to solve the problem. Our approach is based on constructing logical models for considered problem. Also we consider genetic and local search algorithms for the problem. The book should be especially useful to professionals in modular robotics.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the theory, design and applications of computer networks, distributed computing and information systems. Networks of today are going through a rapid evolution, and there are many emerging areas of information networking and their applications. Heterogeneous networking supported by recent technological advances in low-power wireless communications along with silicon integration of various functionalities such as sensing, communications, intelligence and actuations is emerging as a critically important disruptive computer class based on a new platform, networking structure and interface that enable novel, low-cost and high-volume applications. Several of such applications have been difficult to realize because of many interconnections problems. To fulfill their large range of applications, different kinds of networks need to collaborate, and wired and next-generation wireless systems should be integrated in order to develop high-performance computing solutions to problems arising from the complexities of these networks. The aim of the book “Advanced Information Networking and Applications” is to provide latest research findings, innovative research results, methods and development techniques from both theoretical and practical perspectives related to the emerging areas of information networking and applications.
Download or read book DYNAMIC STABILITY ANALYSIS OF MODULAR SELF RECONFIGURABLE ROBOTIC SYSTEMS written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, an efficient algorithm has been developed for the dynamic stability analysis of self-reconfigurable, modular robots. Such an algorithm is essential for the motion planning of self-reconfigurable robotic systems. The building block of the algorithm is the determination of the stability of a rigid body in contact with the ground when there exists Coulomb friction between the two bodies. This problem is linearized by approximating the friction cone with a pyramid and then solved, efficiently, using linear programming. The effects of changing the number of faces of the pyramid and the number of contact points are investigated. A novel definition of stability, called percentage stability, is introduced to counteract the adverse effects of the static indeterminacy problem between two contacting bodies. The algorithm developed for the dynamic stability analysis, is illustrated via various case studies using the recently introduced self-reconfigurable robotic system, called I-Cubes.

Book excerpt: It is man’s ongoing hope that a machine could somehow adapt to its environment by reorganizing itself. This is what the notion of self-organizing robots is based on. The theme of this book is to examine the feasibility of creating such robots within the limitations of current mechanical engineering. The topics comprise the following aspects of such a pursuit: the philosophy of design of self-organizing mechanical systems; self-organization in biological systems; the history of self-organizing mechanical systems; a case study of a self-assembling/self-repairing system as an autonomous distributed system; a self-organizing robot that can create its own shape and robotic motion; implementation and instrumentation of self-organizing robots; and the future of self-organizing robots. All topics are illustrated with many up-to-date examples, including those from the authors’ own work. The book does not require advanced knowledge of mathematics to be understood, and will be of great benefit to students in the robotics discipline, including in the areas of mechanics, control, electronics, and computer science. It is also an important source for researchers who wish to investigate the field of robotics or who have an interest in the application of self-organizing phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: Technological advances especially in the miniaturization of robotic devices foreshadow the emergence of large-scale ensembles of small-size resource-constrained robots that distributively cooperate to achieve complex tasks (e.g., modular self-reconfigurable robots, swarm robotic systems, distributed microelectromechanical systems, etc.). These ensembles are formed from independent, intelligent and communicating units which act as a whole ensemble. These units cooperatively self-organize themselves to achieve common goals. These systems are tought to be more versatile and more robust than conventional robotic systems while having at the same time a lower cost.These ensembles form complex asynchronous distributed systems in which every unit is an embedded system with its own but limited capabilities. Coordination of such large-scale distributed embedded systems poses significant algorithmic issues and open for new opportunities in distributed algorithms. In my thesis, I defend the idea that distributed algorithmic primitives suitable for the coordination of these ensembles should be both identified and designed.In this work, we focus on a specific class of modular robotics systems, namely large-scale distributed modular robotic ensembles composed of resource-constrained modules that are organized in a lattice structure and which can only communicate with neighboring modules. We identified and implemented three building blocks, namely centrality-based leader election, time synchronization and self-reconfiguration.We propose a collection of distributed algorithms to realize these primitives. We evaluate them using both hardware experiments and simulations on systems ranging from a dozen of modules to more than a dozen of thousands of modules. We show that our algorithms scale well and are suitable for large-scale embedded distributed systems with scarce memory and computing resources.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces interesting topics, from concepts to the latest research, on cellular and micro robotic systems. The cellular robotic system is a self-organizing robotic system composed of a large number of autonomous robotic units, named cells. This idea came from the organic structure of a living body. Several attractive topics in this area are covered, such as swarm intelligence, communications, and robotic mechanisms. The micro robotic system is currently the most fascinating technology. Micro mechanisms, control and intelligence, with respect to this system are treated here. The combination of both technologies will prepare the way for a new paradigm in the field of engineering.

This book was released on 2014-09-25 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how the principle of self-sufficiency can be applied to a reconfigurable modular robotic organism. It shows the design considerations for a novel REPLICATOR robotic platform, both hardware and software, featuring the behavioral characteristics of social insect colonies. Following a comprehensive overview of some of the bio-inspired techniques already available, and of the state-of-the-art in re-configurable modular robotic systems, the book presents a novel power management system with fault-tolerant energy sharing, as well as its implementation in the REPLICATOR robotic modules. In addition, the book discusses, for the first time, the concept of “artificial energy homeostasis” in the context of a modular robotic organism, and shows its verification on a custom-designed simulation framework in different dynamic power distribution and fault tolerance scenarios. This book offers an ideal reference guide for both hardware engineers and software developers involved in the design and implementation of autonomous robotic systems.
Download or read book Discovering Distributed Locomotion Algorithms for Self Reconfigurable Cellular Robots written by Akhila Reddy Magam and published by . This book was released on 2008 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-reconfigurable modular robots are distributed robots that reconfigure via autonomous movement decisions made by their modules. Such robots have been widely studied in the literature, but in almost all cases, the rules for their reconfiguration and locomotion are hand-crafted. The work reported in this thesis seeks to automate this process using evolutionary search methods for the discovery of distributed locomotion algorithms. Cellular automata-based rules are evolved to achieve autonomous locomotion in an environment with obstacles. A standard genetic algorithm (GA) approach is tried first, and shown to be inadequate. A staged version of evolutionary algorithms is then developed, and applied to three complex situations. In each case, this approach is able to find reasonable solutions. A simulator for an abstract homogeneous self-reconfigurable robotic system was developed to simulate a two-dimensional robot moving in a two-dimensional environment. This simulator was used to evaluate the performance of locomotion algorithms using several fitness criteria during and after the evolutionary search. Results from the standard GA-based approach are compared with those obtained from the staged approach using three locomotion problems. The discovered robot behavior indicates that the multi-stage approach exhibits better performance than the standard GA approach. Experimental results also show that the algorithms produced by the multi-stage approach are more easily adaptable to different environments when compared to those found using the standard approach.
