The publisher's blurb suggests that this is a book containing a number of NEW projects but it is really an EXACT reprint of "LEGO Mindstorm Masterpieces: Building and Programming Advanced Robots" with an updated cd. Although the cd includes PDFs of a few other books it does not include the cds shipped with those books so you are better off buying the books themselves, and the chances are that if you are looking to buy this book, you already have those other books. Similarly, the cd includes some software for drawing LEGO diagrams, etc. but offers no information on how to use these programs effectively so you could just as easily download the software and find guidance on using it on the internet. Unfortunately, the software that is provided does not include any of the programming tools or alternative firmware installs available to enhance your robot's behaviour. Overall, if you do not already own a copy of "LEGO Mindstorm Masterpieces" then this book is worth the money, but if you do, consider yourself warned.
