This book consolidates the current state of knowledge on implementing cooperating robot-based systems to increase the flexibility of manufacturing systems. It is based on the concrete experiences of experts, practitioners, and engineers in implementing cooperating robot systems for more flexible manufacturing systems. Thanks to the great variety of manufacturing systems that we had the opportunity to study, a remarkable collection of methods and tools has emerged. The aim of the book is to share this experience with academia and industry practitioners seeking to improve manufacturing practice. While there are various books on teaching principles for robotics, this book offers a unique opportunity to dive into the practical aspects of implementing complex real-world robotic applications. As it is used in this book, the term “cooperating robots” refers to robots that either cooperate with one another or with people. The book investigates various aspects of cooperation in the context of implementing flexible manufacturing systems. Accordingly, manufacturing systems are the main focus in the discussion on implementing such robotic systems. The book begins with a brief introduction to the concept of manufacturing systems, followed by a discussion of flexibility. Aspects of designing such systems, e.g. material flow, logistics, processing times, shop floor footprint, and design of flexible handling systems, are subsequently covered. In closing, the book addresses key issues in operating such systems, which concern e.g. decision-making, autonomy, cooperation, communication, task scheduling, motion generation, and distribution of control between different devices. Reviewing the state of the art and presenting the latest innovations, the book offers a valuable asset for a broad readership.

The papers presented at the Second International Conference on Robotics and Factories of the Future held in San Diego, California, USA during July 28-31, 1987 are compiled in this volume. Over two hundred participants attended the conference, made technical presentations and discussed about various aspects of manufacturing, robotics and factories of the future. The number of papers published in this volume and the number of unpublished presentations at the conference indicates the evidance of growing interest in the areas of CAD/CAM, robotics and their role in future factories. The conference consisted of five plenary sessions, twenty three technical sessions, workshops, and exhibits from local industries and educational institutions. I wish to acknowledge with many thanks the contributions of all the authors who presented their work at the conference and submitted the manuscripts for publication. It is also my pleasure to acknowledge the role of keynote, banquet, and plenary sessions speakers whose contributions added greatly to the success of the conference. My sincere thanks to all session chairmen. I wish that the series of the International Conferences on Robotics and Factories of the Future which was initiated in 1984 in Charlotte, North Carolina will have a major impact on the use of robots and computers in the automated factories of the future.

The drive to reduce costs and enhance competitiveness in manufacturing industry has led to greatly increased interest in industrial automation, particularly for small and medium sized enterprises. Although manufacturing robots and flexible machining systems (FMS) are no longer the exclusive preserve of the major industrial multi-nationals, their adoption has not been as widespread or as effective as was once predicted. The purpose of this book is to examine the international patterns of development and adoption of flexible automated manufacturing, to identify current and future best practice particularly in the emerging technology of robotic assembly, and to show how technology, industrial flexibility and competitiveness are inter-related.

Surveys the wide spectrum of automated systems available to improve manufacturing productivity including robots, numerical control machines, programmable controllers, computer controllers and microprocessor-based automated systems. Completely updated, it features industry case studies, revised and expanded problem sections and new material on product design, CAD, Karnaugh Maps and CIM.

Much has been said and written about Japan's manufacturing prowess. Most ofthe comment comes from people who are merely visitors to the country and can be best cIassified as 'observers looking in from the outside'. Other views come from the Japanese themselves in which the double barrier of culture and language filters out much information that would be of real value to Western industrialists. Neither of these limitations apply to John Hartley, who has been resident in Japan for the past five years. He understands the culture, can speak the language and has extensive contacts at the highest level. Therefore, he is in a unique position to report on the Japanese scene and its activities in advanced manufacturing technology. This he has been doing on a regular basis to IFS magazines: The Industrial Robot, Assembly Automation, Sensor Review and The FMS Magazine. Most of the material in this book is from John Hartley's 'pen' and represents his most significant contributions on flexible automation in Japan to these journals over the last three years. It is augmented with a few other articles written by leading authorities on new technology in Japanese manufacturing industry.

From its inception in 1983, ESPRIT (the European Strategic Programme for Research and Development in Information Technology) has aimed at improving the competitiveness of European industry and providing it with the technology needed for the 1990s. Esprit Project 623, on which most of the work presented in this book is based, was one of the key projects in the ESPRIT area, Computer Integrated Manufacturing (CIM). From its beginnings in 1985, it brought together a team of researchers from industry, research institutes and universities to explore and develop a critical stream of advanced manufacturing technology that would be timely and mature for industrial exploitation in a five year time frame. The synergy of cross border collaboration between technology users and vendors has led to results ranging from new and improved products to training courses given at universities. The subject of Esprit Project 623 was the integration of robots into manufacturing environments. Robots are a vital element in flexible automation and can contribute substantially to manufacturing efficiency. The project had two main themes, off-line programming and robot system planning. Off-line programming enlarges the application area of robots and opens up new possibilities in domains such as laser cutting, and other hazardous operations. Reported benefits obtained from off-line program ming include: - significant cost reductions because re-programming eliminates robot down-time; - faster production cycles, in some cases time-savings of up to 85% are reported; - the optimal engineering of products with improved quality.
