It can be used by practicing engineers and scientists—or as a text in standard university courses in robotics. The book has extensive coverage of the major robotic classifi cations, including Wheeled Mobile Robots, Legged Robots, and the Robotic Manipulator. A central theme is the importance of kinematics to robotic principles. The book is accompanied by a CD-ROM with MATLAB ® simulations, photographs, tutorials, and third-party software (see On the CD-ROM section). FEATURES ■ Discusses the major robot classifi cations including Wheeled Mobile Robots, Legged Robots, and the Robotic Manipulator ■ Provides an introduction to basic mechanics and electronics; presents math- ematical modeling concepts; and performs robotic simulations using MATLAB ■ Includes extensive coverage of kinematics—integrated throughout the book whenever appropriate ■ Includes a CD-ROM with demos, MATLAB simulations, photos, and more BRIEF TABLE OF CONTENTS 1.
