Forget roboreptile, buy this book and build your own robot! Why spend a lot of money on this year's big thing in robots - Roboreptile - and wind up with something that can only do a few basic commands and then falls over? Instead, buy this book, and you and your child can bond while building your own robots. This is a very healthy update to the 2nd edition, and makes it well worth your while to purchase, read, and use as a reference book. The third edition has been updated to show most of the latest technologies that robot builders have been using. Gordon has done a very good job at organizing a wide variety of current information into his book, and Myke Predko is a welcome addition to the authoring team, bringing with him is vast knowledge of microcontrollers. This book covers much of the basics of building robots.
