Since the NXT 2.0 set was released this year, many people have been asking whether many of the existing NXT books on the market are compatible with the 2.0 kit. Generally, the answer is no, and my book is no exception. The Unofficial LEGO MINDSTORMS NXT Inventor’s Guide was written for the first version of the NXT set (#8527), and its projects are only compatible with the first version (what I call the NXT 1.0 set). In other words, because of piece differences between the NXT 1.0 and 2.0 sets, the projects in my book can only be built with an NXT 1.0 set. However, much of the other information is still helpful. Much of the building, mechanical, and programming information is still applicable.
So what if you’re the proud owner of an NXT 2.0 set and want to use the NXT Inventor’s Guide with it? I’m currently working with my book’s publisher, No Starch Press, to get out a second edition specifically for the NXT 2.0 set. I do not yet have a firm release date for the book. In the meantime, you will need to either purchase an NXT 1.0 set or hunt down the necessary pieces to build the robots if you own only an NXT 2.0 set. The second option can be difficult although this resource might help.
