Hands-On Robotics Programming with C++

By: Dinesh Tavasalkar, Lentin Joseph

Overview of this book

C++ is one of the most popular legacy programming languages for robotics, and a combination of C++ and robotics hardware is used in many leading industries. This book will bridge the gap between Raspberry Pi and C/C++ programming and enable you to develop applications for Raspberry Pi. You'll even be able to implement C programs in Raspberry Pi with the WiringPi library. The book will guide you through developing a fully functional car robot and writing programs to move it in different directions. You’ll then create an obstacle-avoiding robot using an ultrasonic sensor. In addition to this, you’ll find out how to control the robot wirelessly using your PC or Mac. This book will also help you work with object detection and tracking using OpenCV, and guide you through exploring face detection techniques. Finally, you will create an Android app and control the robot wirelessly with an Android smartphone. By the end of this book, you will have gained experience in developing a robot using Raspberry Pi and C/C++ programming.

Creating a voice-controlled bot app

The voice-controlled bot application is the main focus of this chapter. The following are the three main parts involved in creating a voice-controlled robot:

  • A voice recognition application: The voice recognition application will recognize our voice and send data as text when a particular word is recognized. For example, if we say the word forward, the application would send an F to the robot.
  • Bluetooth connection: This involves establishing a working connection between the Bluetooth of the smartphone and the Bluetooth of the RPi.
  • RPi Robot program: In this section, we will decode the text information that is transmitted from the smartphone and move the robot accordingly. For example, if the incoming text is F, then we will write a program to move the robot forward.

In this section, we will create a voice recognition application. In the...
