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.

Building an object-following robot

After thresholding an image and viewing the video feed from the Pi camera, we will combine both of these programs to create our object-following robot program.

In this section, we will write two programs. In the first program, we place the ball in front of the camera and trace it by creating a dot (using moments) in the center of the ball. Next, we will move the ball up, down, left, and right and note the point values at different positions on the camera.

In the second program, we will use these point values as an input and make the robot follow the ball object.

Ball tracing using moments

Before following the ball, the robot should first be able to trace it using the Pi camera. Before writing...
