Extreme NXT: Extending the LEGO MINDSTORMS NXT to the Next Level, Second Edition (Technology in Action)

Extreme NXT: Extending the LEGO MINDSTORMS NXT to the Next Level, Second Edition (Technology in Action) Review

Although LEGO MINDSTORMS NXT allows anyone to build complex inventions, there are limits to what you can do with what comes inside the box. This book shows you how to advance the NXT with more than 45 exciting projects that include creating a cool magic wand that writes words in thin air, building a remotely guided vehicle, and constructing sophisticated robots that can sense color, light, temperature, and more. All projects are explained with easy-to-follow, step-by-step instructions, so you’ll be able to create them successfully whether you’re a novice or an expert. This book also shows you how to expand the programming software and use the alternative language NXC.

New input devices—such as keypads, sensors, and even the human body—are covered, along with fun games such as surfing, PONG, and SIMON. On the serious side, there are classic engineering challenges such as controlling an inverted pendulum, making a robot that follows a wall, and building several light-seeking vehicles. Some projects are just entertaining, such as the Etch-A-NXT; others are useful, such as a motorized camera mount that takes panoramic photographs.

This second edition accounts for the important changes found in the next generation NXT, and it also covers the original concepts in greater depth. Details are presented for practically unlimited expansion of the NXT inputs and outputs by using the I2C communications bus, and several power amplifier designs allow the NXT outputs to drive bigger motors. Instructions are also included for adapting LEGO Power Functions motors to work directly with the NXT.

The NexStar User's Guide

The NexStar User's Guide Review

Michael Swanson’s online discussions with literally thousands of NexStar owners made it clear that there was a desperate need for a book such as this – one that provides a complete, detailed guide to buying, using and maintaining NexStar telescopes. Although this book is highly comprehensive, it is suitable for beginners – there is a chapter on "Astronomy Basics" – and experts alike.

Celestron’s NexStar telescopes were introduced in 1999, beginning with their first computer controlled "go to" model, a 5-inch. More models appeared in quick succession, and Celestron’s new range made it one of the two dominant manufacturers of affordable "go to" telescopes.

RobotBASIC Projects for the Lego NXT: Robot Programming for Beginners

RobotBASIC Projects for the Lego NXT: Robot Programming for Beginners Review

Lego’s NXT system allows you to snap together a robot base complete with a variety of self-contained, modular sensors and motors. The problem with the NXT Robot though is software. While the visual programming language that ships with the system is supposed to be easy-to-use for beginners, many find it far from intuitive. Unless the tasks you are attempting are rudimentary and uncomplicated you may find the NXT’s programming procedures difficult to comprehend. Even many of the after-market languages available for the NXT have cryptic syntax that can frustrate a new user. One solution to these problems is RobotBASIC. Its easy-to-use English-like syntax makes programming easy to grasp, even for beginners. We provide a library of routines that allow you to control the NXT without downloading anything to the robot itself. RobotBASIC controls the NXT’s motors and reads sensory data by talking directly to the NXT computer using Lego’s wireless protocol. With our system, you program totally on the PC and when your program is ready, just run it and watch the robot respond. We also provide a Lego Simulation Library that allows your NXT programs to operate with the RobotBASIC simulator, letting students experiment even when the Lego hardware is not available. Every student can work with their own simulated robot both at home and in the classroom and when someone gets their program working, just plugging in a USB Bluetooth adapter will instantly allow their program to control the real NXT. This system makes programming easier to understand because the user can concentrate on concepts rather than cryptic syntax or an unintuitive graphical interface. Finally, RobotBASIC is a powerful, full-featured robot-control language, so after you have learned all you can from the NXT you can still use the RobotBASIC skills you learn from this book when you move on to other hardware technologies with more options and capabilities.
