This edition is a major revision that includes new content on Robot Operating System, CAD Design, 3D Printing, and Microcontrollers. Building a bridge between technicians, who have hands-on experience, and engineers with a deeper insight into the workings, the book covers a range of machines, from arm, wheel, and leg robots to flying robots and robotic submarines and boats. Additionally, a formal introduction to Robot Dynamics for both Mobile and Arm Robots has been added. Unlike most books in this field, this text offers a complete set of topics from electronics, mechanics, and computer interface and programming, making it an independent source for knowledge and understanding of robotics.
