Written by three world-leading experts in LEGO Mindstorms homebrew hardware, this book contains the detailed instructions for the construction of sensors and other extensions to the NXT. Over 15 projects are explained with well-illustrated, clear, step-by-step instructions so people with even limited experience in electronics can follow. This book is for intermediate-level users of NXT who would like to advance their capabilities by learning some of the basics of electronics. It makes a great reference for the NXT hardware interfaces. Examples even come complete with multiple, alternative NXT languages.

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 popularity of NXT and the success of The Da Vinci Code are combined in this fascinating book. Projects for building and programming five of Leonardo's most famous inventions are covered in detail: the tank, the helicopter, the catapult, the flying machine, and the revolving bridge. This book is written for serious NXT programmers and covers the most popular programming environments available today. The book is abundantly illustrated and includes sample code and countless best-practices strategies.

This book offers a remarkable collection of chapters covering a wide range of topics related to ICT applications in agriculture and the environment. It gathers the proceedings of the 2nd International Conference on ICTs in Agronomy and Environment (CITAMA 2019), held in Guayaquil, Ecuador on January 22–25, 2019. The conference attracted a total of 27 papers, submitted by pioneering researchers from countries around the globe. Following a thorough peer-review by leading experts, only 14 papers were ultimately selected for publication. They cover a diverse range of topics, including: intelligent and knowledge-based systems; the Internet of things and monitoring systems; image processing; and social and collaborative systems. The book offers a valuable resource for a broad readership, including researchers, educators, undergraduate and graduate students, as well as professionals from the areas of ICT, Agriculture and Environment.

Today, the development of robots is making steady advances. In particular, the Robot Operating System (ROS) offers a unified platform that greatly facilitates the development of robots and has become a new hotspot for learning and application in the field of robotics research.This book introduces readers to the key technologies and development methods for ROS-based intelligent robots. Covering both the development history of robots and various aspects of programming robots, it offers effective support for beginners.The book is divided into three parts, the first of which introduces the basics of robots, including their definition, development, composition, and key technologies. In turn, the second part covers the hardware and software components and the implementation of functions such as vision, speech, grasping, and autonomous navigation. These functions need to work together to provide user-friendlier and more intelligent service. The third part shows how to develop robots with different functions in different application scenarios.Combining theoretical and practical aspects, with a strong focus on application, this work can be used as a reference book for robotics-related courses. Moreover, it will benefit all readers who are interested in intelligent robot development, sharing essential insights into developing service robots based on ROS.
