Overview of this book

The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The Raspberry Pi is known as a tiny computer built on a single circuit board. It runs a Linux operating system, and has connection ports for various peripherals so that it can be hooked up to sensors, motors, cameras, and more. Raspberry Pi has been hugely popular among hardware hobbyists for various projects, including robotics. This book gives you an insight into implementing several creative projects using the peripherals provided by Raspberry Pi. To start, we’ll walk through the basic robotics concepts that the world of Raspberry Pi offers us, implementing wireless communication to control your robot from a distance. Next, we demonstrate how to build a sensible and a visionary robot, maximizing the use of sensors and step controllers. After that, we focus on building a wheeled robot that can draw and play hockey. To finish with a bang, we’ll build an autonomous hexcopter, that is, a flying robot controlled by Raspberry Pi. By the end of this book, you will be a maestro in applying an array of different technologies to create almost any imaginable robot.

Downloading and installing OpenCV – a fully featured vision library


Now that you have your camera connected, you can access the amazing capabilities that have been provided by the open source community. Open a terminal window and type the following commands:

  1. sudo apt-get update: You're going to download a number of new software packages, so it is better to make sure that everything is up to date.

  2. sudo apt-get install build-essential: Although, you may have done this earlier, the library is essential for building OpenCV.

  3. sudo apt-get install libavformat-dev: This library provides a way to code and decode the audio and video streams.

  4. sudo apt-get install ffmpeg: This library provides a way to transcode the audio and video streams.

  5. sudo apt-get install libcv2.4 libcvaux2.4 libhighgui2.4: This command shows the basic OpenCV libraries. Note the number in the command. This will almost certainly change as the newer versions of OpenCV become available. If 2.4 does not work, then either try 3.0 or...
