The new NXT book that we, The NXT Step blogger team, have been working on is in full-swing. We can't comment (yet) on any specific robots that will be included in the book (there will be 9 of them with full building instructions and programming steps in a CAD format), but there will also be 9+ chapters from various blog contributors on different topics that readers might find of interest.
My chapter is on debugging and includes some tips on troubleshooting your NXT-G programs. Many of these will come as no surprise to experienced programmers, but newcomers to NXT-G (and programming, in general) will hopefully find some helpful stuff in there for helping with pesky programs.
We're working hard on this book - no expected due date yet, but it won't be too long. Some of my fellow contributors might chime in and give some hints about their book material, too. There are some things we can't talk about yet (such as the robots) but we'll answer the questions we can if you've got them...
I hope everyone had a safe and Happy New Year - now it's back to work!
