The book takes a hands-on approach to robot-building, and the author goes out of the way not by promising a gizmo but rather a simple acoustic-controlled car trolley which can be extended to pave the way for a more advanced project. A course in basic electronics is recommended, the book also covers sufficient details so as not to require much knowledge initially. But the fun part of the book is the amount of possibilities that the author has actually tried out with the robot - this includes following a chalk line on pavements, and even seeking and plugging into a battery charger when its supplies go low! This is definitely a book worth treasuring, and moreover - IMPLEMENTING!
