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.

Constructing and connecting the robot

Constructing the robot properly is one of the most important steps. A properly constructed robot will move smoothly without any obstructions. Before constructing the robot, let's take a look at the complete list of components that you will need.

The parts required for building the robot include the following:

  • A robot chassis, which must include the following components:
    • An upper plate and a lower plate
    • Two BO DC motors (BO is a type of DC motor that generally is yellow in color)
    • Two wheels
    • One castor wheel
    • Spacers
    • Screws for connecting different parts
  • One screwdriver
  • One L298N motor driver
  • Seven or eight connecting wires
  • One battery snapper
  • One 9V battery

Since these robot chassis are created by small-scale companies and there isn't a standard robot chassis that is available internationally, the robot chassis that I'm using...
