This book describes the mathematical foundations, especially geometric, underlying the motions and force-transfers in robots. The principles developed can be applied to both control of robots and the design of their major moving parts. Comprehensive coverage of the screw and its geometry bridges the gap between screw theory and traditional mechanics but no prior knowledge of screw theory is assumed. The reader is introduced to the screw with a simple planar example and progresses to robots that move three-dimensionally. Containing many illustrative examples, over 300 exercises, and a chapter...
