Robot Analysis: The Mechanics of Serial and Parallel Manipulators, 1999, Wiley & Sons

This textbook provides the fundamental knowledge needed for understanding the mechanics of both serial and parallel manipulators. It offers an in-depth treatment of the position analysis, Jacobian analysis, stiffness analysis, and dynamical analysis of both types of manipulators, including a discussion of industrial and research applications.

Mechanism Design: Enumeration of Kinematic Structures According to Function, 2000, CRC Press

This textbook introduces a systematic methodology for the creation and classification of mechanisms. The approach is based on the idea that some of the functional requirements of a class of mechanisms can be transformed into structural characteristics. The kinematic structures of the same nature can be enumerated in a systematic and unbiased manner by using graph theory and combinatorial analysis.
