Prof. John J. Craig taught at the Department of Electrical Engineering, Stanford University. His book Introduction to Robotics: Mechanics and Control evolved from class notes used to teach an introductory course on robotics at Stanford University during the autumns of 1983 through 1985. Over the next few years, Prof. Craig actively collaborated with his associates at Stanford, SILMA Inc., and Adept to fine-tune and enhance this book’s content, thus contributing to its relevance for students of today. Further, in 1987, his PhD thesis on “Adaptive Control of Mechanical Manipulators” was published by the International Journal of Robotics Research and received critical acclaim.
