"《技术在行动：入门级机器人编程与Raspberry Pi和Arduino》是一本专为对科技感兴趣的极客玩家量身打造的书籍，特别是那些热衷于探索树莓派（Raspberry Pi）和Arduino平台的读者。作者Jeff Cicolani深入浅出地讲解如何利用Python和OpenCV进行机器人开发，引导读者从基础开始，逐步进入机器人技术的世界。该书详细介绍了如何通过这两个开源硬件平台构建机器人，Python作为脚本语言，因其易学性和强大的功能，在机器人控制和数据处理中扮演着关键角色。OpenCV则是一个广泛应用于计算机视觉领域的库，它能够帮助机器人理解和理解其周围环境，实现诸如物体识别、图像处理等功能。书中内容包括但不限于：搭建Raspberry Pi和Arduino的基本环境，编写控制电路和传感器交互的Python代码，使用OpenCV进行实时视频分析，以及设计简单的机器人控制系统。此外，本书还涉及了机器人的运动控制、路径规划和避障算法等核心概念。本书特别强调实践操作，每个章节都配以清晰的示例和指导，让读者能在动手操作中学习理论知识。此外，它还涵盖了版权信息，指出所有内容受版权保护，未经许可不得复制或以任何形式进行商业用途，确保了知识的合法传播。《 Beginning Robotics with Raspberry Pi and Arduino: Using Python and OpenCV》是一本适合初学者入门的机器人开发指南，无论你是想踏入机器人领域的新手，还是希望提升现有技能的工程师，都将从中获益匪浅。它不仅提供了理论知识，也提供了实际项目开发的宝贵经验，是推动创新和科技进步的重要资源。"

Robotics Basics

I like to tell people who are new to robotics, or are just robotics curious, is

that a robot consists of three elements.

• The ability to gather data

• e ability to process, or do something with the

gathered data

• The ability to interact with the environment

In the following chapters, we apply this principal to build a small

mobile robot. We will use ultrasonic rangefinders and infrared sensors to

gather data about the environment. Specifically, we will identify when there

is an object to be avoided, when we are about to drive off the edge of a table,

and the contrast between the table and the line that we will follow. Once we

have this data, we will apply logic to determine the appropriate response.

We will use Python in a Linux environment to process the information

and send commands to our motors. I chose Python as the programming

language because it is easy to learn, and you don’t have to have a complex

development environment to build some pretty complex applications.

Our interaction with the environment will be simply to control the

speed and direction of motors. This will allow our robot to move about

freely on the table or floor. There really isn’t much to driving a motor.

We will look at two ways of doing it: with a motor driver made for the

Raspberry Pi and with a common motor controller.

This book is intended to be challenging. I cover some pretty complex

material and I do it quickly. There is no way that I can provide detailed

coverage on any of these topics, but I hope to get you to a functional robot

by the end of the book. In each chapter, I try to provide you with more

resources to follow up on the topics discussed. You will struggle at times; I

did and I frequently still do.

Chapter 1 IntroduCtIon torobotICs

Not everyone will be interested in all the subjects. The expectation is

that you will expand on the areas that interest you the most outside of this

book. Persistence pays off.

At the end of the book, I add a little more challenge. In Chapter 9, we

begin leveraging the real power of the Raspberry Pi. We look at computer

vision. Specifically, we look at an open source package called OpenCV (CV

stands for computer vision). It is a common and very powerful collection

of utilities that make working with images and video streams very easy.

It’s also a six-hour build on the most recent version of the Raspberry Pi. To

make things a little easier and a lot less time-consuming, I have available

for download a version of the operating system with OpenCV already

installed. I discuss this more in Chapter 2.

Linux andRobotics

Linux is a Unix-based operating system. It is very popular with

programmers and computer scientists because it’s simple and

straightforward. They seem to enjoy the text-based interface of the

terminal. Yet, for many others, including me, Linux can be very

challenging. So, why in the world would I choose this environment for an

introduction-to-robotics book? The answer to that question is threefold.

First, when you work with robotics, you eventually have to confront

Linux. That’s just a fact. You can do a lot without ever typing a single sudo

command, but you will have limited capabilities. The sudo command stands

for super user do in Linux. This tells the operating system that you are about

to perform a protected function that requires more than general user access.

You will learn more about this when we begin working with the Raspberry Pi.

Second, Linux is challenging. As I stated before, this book will challenge

you. If you have worked in Linux before, then this reason doesn’t apply to

you. However, if you are new to Linux, the Raspberry Pi, or working in a

command line, then some of the things that we do will be challenging. And

that’s good. You’re learning something new and it should be a challenge.
