BeagleBone Robotic Projects. - Second Edition

Overview of this book

BeagleBone Blue is effectively a small, light, cheap computer in a similar vein to Raspberry Pi and Arduino. It has all of the extensibility of today’s desktop machines, but without the bulk, expense, or noise. This project guide provides step-by-step instructions that enable anyone to use this new, low-cost platform in some fascinating robotics projects. By the time you are finished, your projects will be able to see, speak, listen, detect their surroundings, and move in a variety of amazing ways. The book begins with unpacking and powering up the components. This includes guidance on what to purchase and how to connect it all successfully, and a primer on programming the BeagleBone Blue. You will add additional software functionality available from the open source community, including making the system see using a webcam, hear using a microphone, and speak using a speaker. You will then learn to use the new hardware capability of the BeagleBone Blue to make your robots move, as well as discover how to add sonar sensors to avoid or find objects. Later, you will learn to remotely control your robot through iOS and Android devices. At the end of this book, you will see how to integrate all of these functionalities to work together, before developing the most impressive robotics projects: Drone and Submarine.

Preface

Chapter 6. Providing Speech Input and Output

In this chapter, you'll be adding a microphone and speaker, but more than that, you'll add functionality so that your project can both recognize voice commands and also respond via the speaker. This will free you up from typing in commands and let you interact with your projects in an impressive way.

Besides, what self-respecting robot wants to carry around a keyboard? No, you want to interact in natural ways with your projects, and what you learn in this chapter will enable that.

In this chapter, you'll learn about the following topics:

  • Hooking up speakers and a microphone to make and input sound
  • Using eSpeak to allow your projects to respond in a robot voice
  • Using Pocketsphinx to interpret your commands
  • Providing the capability to interpret your commands and have your robot initiate action
