If all this excellent book did was to provide careful, graduated instruction in robotics and the necessary Arduino skills to complete the
transition from a line-following or wall hugging robot to advanced projects like a workhorse lawnbot and a do-it yourself Segway-clone it would be worth many times the cover price. But, with practical well-illustrated instruction it also provides the physical computing enthusiast with the background they need in sensors and actuators (like accelerometers, H-Bridge Motor Controllers and Arduino Interfacing of DC Servo and Stepper Motors) to complete many advanced projects of all kinds with the Arduino and a variety of embedded processors. Addtional Hackerspace skills such as use of a Dremel Tool, PCB layout with Eagle Cad and homebrew PCB construction round out the skills to complete a wide variety of Electronic and Mechatronic projects.
So, whether your aim is to build personal robotic projects in the Hackerspace, or in K-12 STEM Education and you wish to use the Open Source
easy to implement Arduino Platform, or you need a range of hardware, software and workshop skills to complete your own dream project this book is an excellent and necessary part of your library.
