MindStorms is an absolutely fascinating robot building system for children, adults, and those who don't fit well into either category. This book helps you delve more deeply into the principles behind making really cool robots with MindStorms. The opportunities for learning are just never-ending, and at the same time, the limitless fun anyone can have, from pre-teen to geezer, makes the learning very rewarding. This book helps open this potential.

This book takes you beyond the step-by-step instructions in the Constructopedia, and doesn't shy away from the physical principles behind robots, so it is suited for the more experienced and mentally mature builder. I use it to get ideas for things I can build with my 9-year-old son. It won't be long until he's ready to have a go at the book himself, though.

This is the best book on lego building techniques I've seen so far. The basic mathematical foundation is extensive and done without holes or errors, and the ideas, from the mechanical to the lego-technical are well choosen. Something missing in this book? yes, heavy treathment of diagonal matching gear, but it's partly explained why not... the book is so well written that you probably won't feel it like a loss..
