This book presents the most recent research advances in the theory, design, control and application of robot systems, which are intended for a variety of purposes such as manipulation, manufacturing, automation, surgery, locomotion and biomechanics. The issues addressed are fundamentally kinematic in nature, including synthesis, calibration, redundancy, force control, dexterity, inverse and forward kinematics, kinematic singularities, as well as over-constrained systems. Methods used include line geometry, quaternion algebra, screw algebra and linear algebra. These methods are applied to both parallel and serial multi-degree-of-freedom systems.
