Overview of this book

This book will allow you to take full advantage of Raspberry Pi Zero and Raspberry Pi 3 by building both simple and complex robotic projects. The book takes a mission-critical approach to show you how to build amazing robots and helps you decide which board to use for which type of robot. The book puts a special emphasis on designing mobile (or movable) robots using the Raspberry Pi Zero. The projects will show inexpensive, yet powerful, ways to take full advantage. It will teach you how to program Raspberry Pi, control the movement of your robot, and add features to your robots.

Chapter 3. Building a Wall-E Robot

Now that you've built an R2D2, and you know how to control DC motors and provide sight for your robot, now let's build a robot that you almost certainly have heard of. I am talking about Wall-E. Your robot will have some cool capabilities, including rolling around on two tracks, two arms that move, and a vision system that, thanks to the Microsoft Kinect, will give you not Now your arm with the hand is completeonly a video image but also a depth image.

In this chapter, you'll learn the following:

Using the Raspberry Pi to control two DC motors for a track system
Using an external servo controller to control servos to position simple arms and hands
Creating a program in Linux to control servos and motors
Adding the Microsoft Kinect 360 for not only vision but depth as well

Since you will be creating your own Wall-E without the benefit having the head start of an existing toy, it will be more difficult mechanically, but will provide a...
