Take the NXT Step, May 27, 2010
This review is from: The LEGO MINDSTORMS NXT 2.0 Discovery Book: A Beginner's Guide to Building and Programming Robots (Paperback)
I (a hardware/software developer and radio ham for some 30 years) bought LEGO Mindstorms for my now eight-year-old son last Christmas. Being a LEGO nut since he was old enough not to swallow the pieces, he's had great fun with Mindstorms since then.
But after you've built the models detailed in the Mindstorms kit, where do you go next? The Mindstorms online help is pretty good, but tiresome to read on the screen, and not the best medium for a youngster. The Alpha Rex etc. are impressive but it's hard for a child to try to make his own models of a similar complexity on the basis of the models in the Mindstorms kit. There is a huge gap between copying ready-made models and learning to create real robots from scratch, and Laurens Valk's book fills that gap perfectly.
As "the missing manual", this book thoroughly explains the NXT hardware and NXT-G software, in enough technical detail to satisfy a seasoned programmer like me, but without overloading someone who is completely new to the technology. That is no mean feat!
The building instructions are of a similar quality to those provided in the all-too-slim Mindstorms manual, and my son was able to follow them and the programming instructions with only minimal guidance from me (usually because we hadn't yet read the accompanying text! :-)
Now, there are several ways to approach this book. To get started quickly, you or your child genius can simply follow the detailed building and programming instructions to create any of the eight robots detailed in the book. My son had almost no trouble doing this: in fact, he first went after the more complex models like the Strider featured on the cover, followed by the very impressive Chimney Climber. If, like us, you're new to the LEGO Technic and Mindstorms systems, you'll be surprised how they can be made to do such remarkable things.
The program instructions feature a simplified overview - essentially a flow diagram - that lets you follow the basic structure of the program and learn about loops, "if-then-else" blocks, etc. Your young robotics engineer can learn about the how-and-why of the programs, and gradually improvise to deepen his/her understanding of what the NXT controller is "thinking", and then devise clever ways to change it.
Then there are the challenges, or "discoveries" to use Laurens' word: 87 of them in all. Once we have settled down to reading the book together start-to-finish (give us a chance, we've only had this book for a week!), the discoveries will provide many new paths to explore and consolidate our understanding of robotic systems.
I would have expected to pay three times what Amazon is charging for this book, based on similar books aimed at software developers. At under $20, it is excellent value for money and an essential "NXT" step on any robot designer's path of discovery. Buy it!

A Tremendous NXT Teaching Accomplishment By A Young Roboticist, June 30, 2010
This review is from: The LEGO MINDSTORMS NXT 2.0 Discovery Book: A Beginner's Guide to Building and Programming Robots (Paperback)
From his infectious enthusiasm for the Mindstorms NXT System it might be easy to guess that Laurens Valk was introduced to Lego Robotics at age 13 just five short years ago. But, from the careful logical pedagogy of this book and his interesting approach mixing successively more advanced robots intermixed with a clearly arranged taxonomy of parts, programming tools and motor/drive train and sensor categorization, I would have imagined that this book was written by an excellent teacher with many years of experience bringing engineering concepts to youthful learners. Not only does the book offer a clear top-down beginning to end approach to both the NXT Parts Architecture and NXT-G Programming Language while combining this end-to-end approach with interesting projects of increasing difficulty, but he stimulates the reader with building and programming challenges to increase their skill at independent thought in robot building and programming. Just how far and how thoughtfully Laurens' teaching approach goes is indicated by by his unique system of flowcharting/state diagrams which both provides the logical decisions involved in programming this system with a graphical correspondence to the NXT-G Programming language.
I cannot recommend this book highly enough as an aid to using the Lego Mindstorms NXT 2.0 robotics system, and bringing a
new generation of roboticists and engineers to a deep and intuitive understanding these sciences. This handbook should be included in every Mindstorms NXT Set to insure that the recipient will learn, absorb and extend the concepts which this powerful educational system can teach.

Are you ready for a journey of discovery?, May 10, 2010
This review is from: The LEGO MINDSTORMS NXT 2.0 Discovery Book: A Beginner's Guide to Building and Programming Robots (Paperback)
This book is the culmination of more than a year's work and it shows. It's broken up into 4 parts and will guide you through a journey of discovery. On your route to becoming a robotics master you will build no less than 8 different robots and learn about every aspect of NXT-G programming with the help of 50 sample programs. If that's not enough, you can test just how good you've become with any one of the 85 building and programming challenges.
The building and programming instructions are really nice, clear and clean; it's not hard to tell the author has done this before. Learning to program and build with your new NXT 2.0 kit will be so much more fun with this book by your side. It will knock your socks off (don't worry, there's a robot in the book that can help you pick them up again).
