5.0 out of 5 stars More Details about the book, July 13, 2007

By	J. Kelly "GA Book Fan" (Atlanta, GA) - See all my reviews (REAL NAME)

The book consists of 26 chapters plus 1 appendix.

The first 2 chapters cover the questions of "What is a robot" and "What is a program" and introduce the topic of pseudo code. There are many different methods when it comes to pseudo code, but this method will hopefully help teachers, parents, and students to understand how to take an idea for a program and turn it into actual NXT-G block code.

All 36 blocks are covered (the book is useful for both the retail version software and the educational version), and each block has its own chapter with the exception of a couple of blocks that share a chapter (such as the Random block and Number-To-Text block that share chapter 14).

There is a chapter dedicated to the concept of data plugs and wires (Chapter 7). This can be one of the more confusing elements of NXT-G, so this chapter uses a simplified method of showing how data types (number, text, logic) are passed between blocks.

Another chapter provides a walkthrough on creating a My Block. My Blocks are powerful methods for simplifying NXT-G programs, and this chapter shows how the ability to re-use My Blocks can be helpful.

Finally, the appendix covers some basic math such as converting back and forth between degrees and rotations. It also explains the LCD screen's resolution and how the X/Y coordinates work.

Teachers, parents, coaches, and kids should find this book useful. It's written in a very friendly and easy-to-read style and provides plenty of sample programs in each chapter to demonstrate how to use the blocks. Also, coverage of each block's configuration panel is also provided. Overall, the book can be used as an additional source of information on the NXT-G programming language to supplement the Help files included with the software.

5.0 out of 5 stars Lego Mindstorms NXT_G Programming Guide, August 9, 2007

By	Mike Lawson "MLComputer" (Zanesville, OH USA) - See all my reviews (REAL NAME)

When it comes to wanting to do Lego Mindstorm NXT-G, this is the first book you should get. The book shows the reader what different blocks are and how they work. The book also reads in terms that middle school students can understand and follow. Programming is the most difficult item that you have to do with a roboit. This book shows is a great resource for people that are in to lego roboits.

5.0 out of 5 stars Great resource for NXT-G programming, February 25, 2008

By	John S. Kjellman (Orland Park, IL United States) - See all my reviews (REAL NAME)

This book covers a lot of ground on NXT-G programming and is a must have resource for anyone serious about programming in NXT-G as the on line help included with the NXT set is not adequate.
As a professional programmer and a robotics hobbyist, I would recommend that anyone wanting to bring out the full potential of their NXT creations move to a text based language like Robot-C instead. While NXT-G is good for simple programs, it is just to difficult to create anything of any complexity as the graphical elements and all those connecting lines distract you from what you are trying to accomplish.
I am giving this book 5 stars because it does well at what it is, a reference / guide to the NXT-G programming language. It is NXT-G itself that I would only give 2 stars.
