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.

Controlling your robot from a remote computer


The next step in constructing your laser tag playing robot is to add the remote control. You'll first need to add the ability to control Raspberry Pi via a WLAN connection. As noted in Chapter 1, Adding Raspberry Pi to an RC Vehicle, the section, Accessing the RC Car remotely, showed you how to add a WLAN interface as an access point. To prepare for the next section, you will want to configure two Raspberry Pis with WLAN, one as an access point and other that you'll connect to the access point. You'll also connect a USB web camera to Raspberry Pi on the wheeled robot for control. Finally, when you have logged in to Raspberry Pi, this will function on the remote computer. Log in to the second Raspberry Pi on the wheeled robot by typing ssh –X [email protected], where the xxx.xxx.xxx.xxx is the IP address of Raspberry Pi on the wheeled robot.
