The objective of this book is to show the effect of flexible arm studied by dynamic analysis of a robot manipulator with two flexible arms. The book has been established for the undergraduate upper-levels and graduate level in Mechanical Engineering. Clearly, it is desirable to build lightweight robot arms which have a large working volume, high mobility and the capability to carry heavy payloads. In order to meet these requirements, the robot arm has to be flexible, in other words, the rigid-body-assumption in robotics has to be abandoned. Then, the deflection and vibration of the robot arm present a severe problem to the accuracy and the stability in positioning. Therefore, the control of flexible manipulators is becoming a critical issue in robotics. Modal analysis can improve physical knowledge of a structure and in some cases give us much information about its behaviour during operating. The calculation of the natural frequencies of the structure by modal analysis becomes today...
