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.

Summary

In this chapter, we looked at some of the important functions inside OpenCV libraries. After that, we put these functions to the test and recognized an object from an image. Next, we learned how to read a video feed from the Pi camera, how to threshold a colored ball, and how to place a red dot on top of it. Finally, we used the Pi camera and the ultrasonic sensor to detect the ball and follow it.

In the next chapter, we are going to expand our OpenCV knowledge by detecting human faces using the Haar Cascade. After that, we will recognize a smile and make the robot follow the face.
