Nagata covers both sides of the MindStorms equation--mechanical construction and logical control--very well. Every step in the physical assembly procedure for each robot is clearly illustrated with orthographic drawings similar to those in Lego kit documentation. Color would make these drawings even better (they're printed in contrasting gray tones, with color pictures of each finished project in a center section) but would probably add a lot to the price. The coverage of software is good too, consisting variously (depending on the complexity of the program) of a screen shot of the MindStorms visual programming environment or a listing of Not Quite C (NQC) code. This book achieves what should be the main goal of any book about Lego blocks: it gets the reader thinking about ways to modify and expand on the ideas in it. --David Wall
Topics covered: How to construct and program a variety of creatures, vehicles, and machines with LEGO MindStorms pieces. Projects include (this list is comprehensive) a car, a centipede, a vehicle that skates, a dinosaur, a train that runs on tracks, a walker with articulated legs, a segmented vehicle that will climb over obstacles, an analog clock, a six-legged bug that can be made to turn right and left, and a very (very) cool car, in which the motor is used not for direct propulsion, but to compress air that propels the vehicle forward.
