What is an Artificial Intelligence (AI)-enabled drone and what can it do? Are AI-enabled drones better than human-controlled drones? This book will answer these questions and more, and empower you to develop your own AI-enabled drone. You'll progress from a list of specifications and requirements, in small and iterative steps, which will then lead to the development of Unified Modeling Language (UML) diagrams based in part to the standards established by for the Robotic Operating System (ROS). The ROS architecture has been used to develop land-based drones. This will serve as a reference model for the software architecture of unmanned systems.

A hands-on, beginner-friendly guide to building and programming LEGO robots. You’re the new owner of a LEGO robotics kit. Now what? Getting Started with LEGO MINDSTORMS teaches you the basics of robotics engineering, using examples compatible with the LEGO MINDSTORMS Robot Inventor and SPIKE Prime sets. You’ll be making remote-control vehicles, motorized grabbers, automatic ball launchers, and other exciting robots in no time. Rather than feature step-by-step instructions for building a handful of models, you’ll find essential information and expert tips and tricks for designing, building, and programming your own robotic creations. The book features a comprehensive introduction to coding with Word Blocks, an intuitive visual programming language based on Scratch, and explores topics such as using motors and sensors, building sturdy structures, and troubleshooting problems when things go wrong.

This book aims to cover a new emerging need in designing digital phase shifter for modern communication systems. With the advancement of new generation mobile communication systems, directed beams of antenna arrays save a substantial amount of power as well as improve the communication quality. In this regard, beam-forming circuits, such as digital phase shifters (DPS) constitute essential parts of the antenna array systems. Therefore, this book is devoted to the design of digital phase shifters for various communications systems. Nowadays, phase array systems demand compact phase shifters suitable for chip implementation with wide phase-range and broad frequency band. For each phase shifter topology introduced in this book, the reader is furnished with explicit design equations to construct the circuit under consideration. Furthermore, design equations are programmed using MATLAB to assess the electrical performance of the phase shifters with ideal and lossy components. MATLAB design programs are given at the and of each chapter as appendices and provided as soft copy on the web page of the book.

This book introduces the basic analysis methods in signal processing, principles of various sensors and the concept of measurement system. To make students better understand and apply the theories, the book includes many MATLAB examples, such as the generation of standard signals and the spectrum analysis of audio signals in the signal processing part and Arduino examples as well, such as temperature measuring and ultrasonic ranging to show the applications of sensors. Readers can not only learn the fundamental theories but also get many opportunities to apply the theories to perform measurement tasks. Ultrasonic Ranging Device Based on Arduino: The principle of ultrasonic ranging has already been explained. With an ultrasonic ranging module (HC-SR04), we can build our own ultrasonic ranging device. The reference code below needs a computer to display the measured distance. We recommend you try to add an LCD screen to display the distance and use a battery to power your board, so you can build a portable device.

The ESP 32 is a low cost system on chip series created by express systems. It's an improvement on the popular SB eight two six six that is widely used in Internet of Things products. ESP 32, has both Wi-Fi and Bluetooth capabilities, which make it an all rounded chip for the development of Internet of Things project and embedded systems engineer. Now, in this course, you will learn how to get started with that iOS P32 and learn how to use it to scan Wi-Fi hotspots, control LEDs, buttons, sensors or get sensors reading on our page along with other examples. This course will equip you with the basic knowledge that you will need when working on your ISP. 32 projects in the future. It's basically an Internet of Things development framework that they provide for their boards. There is also Micro Python, jаvascript or Lua, the ones that we are going to use, and this course is Arduino I.D. It requires some adjustments to install the ISP library, but everything will be explained in details in a separate section.
