Python Robotics Projects

Using GPIOs as Input

In the previous chapter, we understood how GPIOs are used for output. But, as the name suggests, the GPIO can be used for both input and output purposes. In this chapter, we will see how you can go ahead and use these pins to input the data over to Raspberry Pi.

The topics which we will cover in this chapter are:

  • A deeper dive into GPIOs
  • Interfacing the PIR sensor
  • Interfacing the ultrasonic proximity sensor
  • Interfacing through I2C

A deeper dive into GPIOs

I am sure you remember this line of code from the previous chapter:

GPIO.setup(18,GPIO.OUT)

As explained earlier, this basically tells us how GPIO the pin will behave in a certain program. By now, you must have guessed that by changing this single line of code we can change the behavior of the pin and convert it from output to input. This is how you would do it:

GPIO.setup(18,GPIO.IN)

Once you write this line of code in your program, the microcontroller will know that during the time that the program is being run, the pin number 18 will only be used for input purposes. 

To understand how this would actually work, let's head back to our hardware and see how it can be done. Firstly, you need to connect an LED to any of the pins; we will be using pin number 23 in this program. Secondly, you need to connect a switch on pin number 24. You can refer...

Interfacing through I2C

So far, so good. Electronic circuits can be very interesting and, while they seem very complex, often we find that the working can be very simple. In the previous section, we interfaced one sensor at a time. We can go ahead and interface multiple sensors, but we are limited by the number of GPIOs that are present. We have also seen that some sensors such as ultrasonic sensors may use more than one GPIO pin for their working. This further reduces the number of sensors that we can interface with the microcontroller. Once we move on to more complex circuits, we will also realize that the wiring can be really messy and if a problem occurs then finding what's wrong becomes one tedious task.

Now, there is an even bigger problem that we face while designing robotic systems and that's the problem of timing—all the work done in a system has to be...

Summary 

This chapter was all about interfacing sensors with GPIOs so that the data can be retrieved by sensors. Moving forward, in the next chapter, with the help of these learned topics, we will learn how to make a pet-feeding robot.

Key benefits

  • • Design, build, and stimulate collaborative robots
  • • Build high-end robotics projects such as a customized personal Jarvis
  • • Leverage the power of Python and ROS for DIY robotic projects

Description

Robotics is a fast-growing industry. Multiple surveys state that investment in the field has increased tenfold in the last 6 years, and is set to become a $100-billion sector by 2020. Robots are prevalent throughout all industries, and they are all set to be a part of our domestic lives. This book starts with the installation and basic steps in configuring a robotic controller. You'll then move on to setting up your environment to use Python with the robotic controller. You'll dive deep into building simple robotic projects, such as a pet-feeding robot, and more complicated projects, such as machine learning enabled home automation system (Jarvis), vision processing based robots and a self-driven robotic vehicle using Python. By the end of this book, you'll know how to build smart robots using Python.

Who is this book for?

If building robots is your dream, then this book is made for you. Prior knowledge of Python would be an added advantage.

What you will learn

  • • Get to know the basics of robotics and its functions
  • • Walk through interface components with microcontrollers
  • • Integrate robotics with the IoT environment
  • • Build projects using machine learning
  • • Implement path planning and vision processing
  • • Interface your robots with Bluetooth

The two first sets of code the book has you write both either result in errors or flat out just don't do what they are intended to do. Doesn't matter if you copy them verbatim from the text. They won't work unless you change them yourselves. The writer tells you to use Broadcom(BCM) in the first code and then changes it to (BOARD) in the next code. The second code doesn't work unless you use BCM, and even then the loop never ends. The text also fails to show the appropriate indent after the range(3): line. The first code wouldn't work because GPIO.out(23.....) needed to be GPIO.ouput(23......), which oddly enough, I figured out because he started using it in the second code. Heck, by the time you make it to the third code, he uses both OUT and OUTPUT. Seriously, do yourself a favor and avoid this absolute train wreck of a book. PackT might want to hire and editor and start some quality control.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
