Dr Richard Grimmet

Dr Richard Grimmet has always been fascinated by computers and electronics from his very first programming project that used Fortran on punch cards. He has a Bachelors and Master’s degree in Electrical Engineering and a PhD in Leadership Studies. He also has 26 years of experience in the Radar and Telecommunications industries, and even has one of the original brick phones. He now teaches Computer Science and Electrical Engineering at Brigham Young University, Idaho, where his office is filled with his many robotics projects. He recently completed a book on using the BeagleBone Black for robotics projects, and another for the Raspberry Pi.

In Detail

Robotics development is accelerating, and an amazing array of new hardware and software capabilities are available to anyone with an interest in the area. Robots will soon be a part of our everyday life, and it will soon be as important to know how they work as it is to know how a computer works. Raspberry Pi is a credit-card sized, fully capable PC that can be used for many of the things that your desktop PC does, such as spreadsheets, word processing, and games.

This book starts with the essentials of turning on the basic hardware. It provides the capability to interpret your commands and have your robot initiate actions. By the time you are through, you’ll have robots that can speak, listen, and move in a number of amazing ways.

This book is a step-by-step projects guide to unlocking some complex and interesting capabilities of Raspberry Pi. Teaching you to use Raspberry Pi from scratch, this book will discuss a wide range of capabilities that can be achieved with it. These capabilities include voice recognition, human-like speech simulation, computer vision, motor control, GPS location, and wireless control. You will then learn how to combine these capabilities to create your own robotics projects.

By the time you have completed this book, you will be able to use Raspberry Pi to create some complex and fascinating robotics projects with a vast array of capabilities.

Approach

This book is for enthusiasts who want to use Raspberry Pi to build complex robotics projects. However, some programming background is recommended. With the aid of the step-by-step instructions in this book, you can construct complex robotics projects that can move, talk, listen, see, swim, or fly.

Who this book is for

Raspberry Pi Robotic Projects is an easy-to-follow, step-by-step projects guide packed full of examples of actual robotics projects. Each topic is explained in detail to make it easy to replicate the projects described.
