Book Description
Arc welding is one of the key processes in industrial manufacturing, with welders using two types of processes - gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). This new book provides a survey-oriented account of the modeling, sensing, and automatic control of the GMAW process.Researchers are presented with the most recent information in the areas of modeling, sensing and automatic control of the GMAW process, collecting a number of original research results on the topic from the authors and colleagues. Providing an overview of a variety of topics, this book looks at the classification of various welding processes; the modeling aspects of GMAW; physics of welding; metal transfer characteristics; weld pool geometry; process voltages and variables; power supplies; sensing (sensors for arc length, weld penetration control, weld pool geometry, using optical and intelligent sensors); control techniques of PI, PID, multivariable control, adaptive control, and intelligent control. Finally, the book illustrates a case study presented by the authors and their students at Idaho State University, in collaboration with researchers at the Idaho National Engineering and Environment Laboratory.

Book Description
Intelligent Seam Tracking for Robotic Welding is part of the Advances in Industrial Control series, edited by Professor M.J. Grimble and Dr. M.A. Johnson of the Industrial Control Unit, University of Strathclyde. This publication discusses in depth the development of a seam tracking system for robotic welding. Various topics are covered including the theory of seam tracking, details of the sub-systems comprising the intelligent seam tracker and the operation of the seam tracking system with coordinated interaction amongst the various sub-systems. The sources of various seam tracking errors and existing seam tracking systems operating in both structured and unstructured welding environments are also addressed. The work reported builds upon the research conducted during the course of the project ARTIST (Adaptive, RealTime, Intelligent Seam Tracker) at the Applied Research Laboratory of the Pennsylvania State University. Although the book is presented in the context of seam tracking, issues related to systems integration are general in nature and relate to other applications as well.

Book Description
This book is the outcome of the NATO Advanced Research Workshop on Machine Intelligence and Knowledge Engineering for Robotic Applications held at Maratea, Italy in May 1986. Attendance of the workshop was by invitation only. Most of the participants and speakers are recognized leaders in the field, representing industry, government and academic c0mrnunity worldwide. The focus of the workshop was to review the recent advances of machine intelligence and knowledge engineering for robotic appli cations. It covers five main areas of interest. They are grouped into five sections: 1. Robot Vision 2. Knowledge Representation and Image Understanding 3. Robot Control and Inference Systems 4. Task Planning and Expert Systems 5. Software/Hardware Systems Also included in this book are a paper from the Poster Session and a brief report of the panel discussion on the Future Direction in Knowledge-Based Robotics. Section I of this book consists of four papers. It begins with a review of the basic concepts of computer vision, with emphasis on techniques specific for robot vision systems. The next paper pre sents a comprehensive 3-D vision system for robotic application.

Book Description
How quickly the technological 'flavour of the month' changes. At the beginning of the 1980's many saw 'robotics' as being something of a pana cea for those problems in the manufacturing industries which had been exacerbated by the world recession. Those working at the time in the field of robotics stressed that robots themselves were only part of the solution. Yet in many quarters the 'hype' for the new technology apparently knew few bounds, resulting, inexorably, in many industries painfully discover ing for themselves a new realism, closely followed by disillusionment. In its wider sense the term 'robotics' covers an extremely broad spec trum of technologies ranging from extremely flexible, highly sensory and integrated systems capable of handling a very diverse product range, through to comparatively inflexible, high volume systems which can merely handle slightly different variations of the same basic product. As a result of the one 'buzzword' referring to such a variety of actual system types, the disillusionment which started to become apparent during the early 1980's acted as something of a double edged sword. A given com pany might consider a particular robotics-based technological solution to its production problems, find that it was unsuitable, and so renounce all robotics approaches as inappropriate. Yet just because one position on that spectrum of technological solutions was unsuitable for the company should not have led them to assume that there was no other robotics solu tion that was appropriate.

Book Description
This volume contains papers presented at the NATO Advanced Research Workshop (ARW) on "Sensors and Sensory Systems for Advanced Robots", which was held in Maratea, Italy, during the week Apri I 28 - May 3, 1986. Participants in the ARW, who came from eleven NATO and two non-NATO countries, represented an i nternat i ona I assortment of d i st i ngu i shed research centers in industry, government and academia. Purpose of the Workshop was to rev i ew the state of the art of sensing for advanced robots, to discuss basic concepts and new ideas on the use of sensors for robot control and to provide recommendations for future research in this area, There IS an almost unanimous consensus among invest i gators in the fie I d of robot i cs that the add i t i on of sensory capabi I ities represents the "natural" evolution of present industrial robots, as wei I as the necessary premise to the development of advanced robots for nonindustrial app I i cat ions. However, a number of conceptua I and techn i ca I problems sti I I challenge the practical implementation and widespread appl ication of sensor-based robot control techn i ques. Cruc i a I among those prob I ems is the ava i lab iii ty of adequate sensors.
