Robotic manipulators are becoming increasingly important in research and industry, and an understanding of statics and kinematics is essential to solving problems of robotics. This book, written by an eminent researcher and practitioner, provides a thorough introduction to statics and first-order instantaneous kinematics with applications to robotics. The emphasis is on serial and parallel planar manipulators and mechanisms. The text differs from others in that it is based solely upon the concepts of classical geometry. It describes how to introduce linear springs into the connectors of parallel manipulators and to provide a proper geometric method for controlling the force and motion of a rigid lamina. Both students and practising engineers will find this book easy to follow, with a clearly written text and abundant illustrations, as well as exercises and real-world projects to work on.

A robot manipulator is a movable chain of links interconnected by joints. One end is fixed to the ground, and a hand or end effector that can move freely in space is attached at the other end. This book begins with an introduction to the subject of robot manipulators. Next, it describes in detail a forward and reverse analysis for serial robot arms. Most of the text focuses on closed form solution techniques applied to a broad range of manipulator geometries, from typical industrial robot designs (relatively simple geometries) to the most complicated case of seven general links serially connected by six revolute joints. A unique feature is its detailed analysis of 6R-P and 7R mechanisms. Case studies show how the techniques described in the book are used in real engineering applications. The book will be useful to both graduate students and engineers working in the field of robotics.

Discover a fresh take on classical screw theory and understand the geometry embedded within robots and mechanisms with this essential text. The book begins with a geometrical study of points, lines, and planes and slowly takes the reader toward a mastery of screw theory with some cutting-edge results, all while using only basic linear algebra and ordinary vectors. It features a discussion of the geometry of parallel and serial robot manipulators, in addition to the reciprocity of screws and a singularity study. All 41 essential screw systems are unveiled, establishing the possible freedom twists and constraint wrenches for a kinematic joint. Familiarizing the reader with screw geometry in order to study the statics and kinematics of robots and mechanisms, this is a perfect resource for engineers and graduate students.
