Robots seem to be everywhere these days. Not only in movies but also in our day-to-day lives. They vacuum floors, play with children, and build automobiles. These new machines are quickly migrating from university and government labs to our homes, offices, schools, and playgrounds. A similar migration has occurred in recent years with computers.

A good part of this migration, as in the case of computers, is that the untrained but interested general population has been able to take part in the development of these new machines. A big reason for this is the introduction of inexpensive hardware and free, open source hardware. Initially, it was Arduino, an inexpensive processor developed for the do-it-yourself crowd, which enabled normal people to create robotics projects with complex functionality. More recently, Raspberry Pi has extended this capability by providing an inexpensive, small, but powerful Linux computer for these projects.

This second edition is designed to allow you to take full advantage of the capabilities of Raspberry Pi in your robotics projects. It will not only teach you how to use the USB port to add additional hardware capabilities, but it will also show you how to connect the hardware to the GPIO as well. It will provide a step-by-step guide to get you well on your way to building your very own amazing robotics projects.
