"This book is an excellent introduction to LEGO robotics and, frankly, is what should have come in the box with the NXT kit. If you want to learn about NXT robots, you need to get this book."
--Joe Dolittle, Computing Unplugged Magazine
"Mindstorms expert David J. Perdue fills his book with plans for the aggressive-sounding Claw-Bot and Guard-Bot, as well as the stationary Golf-Bot. Perdue takes you step by step into the Mindstorms NXT's rich, fascinating little world of pegs, gears, and electronic parts. He also provides guidance for constructing sturdier machines for your next battle of the bots."
