Learn Robotics Programming

By: Danny Staple

Overview of this book

We live in an age where the most difficult human tasks are now automated. Smart and intelligent robots, which will perform different tasks precisely and efficiently, are the requirement of the hour. A combination of Raspberry Pi and Python works perfectly when making these kinds of robots. Learn Robotics Programming starts by introducing you to the basic structure of a robot, along with how to plan, build, and program it. As you make your way through the book, you will gradually progress to adding different outputs and sensors, learning new building skills, and writing code for interesting behaviors with sensors. You’ll also be able to update your robot, and set up web, phone, and Wi-Fi connectivity in order to control it. By the end of the book, you will have built a clever robot that can perform basic artificial intelligence (AI) operations.

Writing the code – testing the sensors

We can now test the sensors out for real. Power up the Pi and motor board and log in.

First, we'll need another library—this time a more general library for talking to devices and sensors connected via the GPIO. Install this on the Pi:

pi@myrobot:~ $ pip install gpiozero

GPIO Zero is a library designed to make interaction with devices attached to the Pi GPIO very simple. It has lots of good examples and documentation on the internet. We will be using it where our hardware does not require more specialist libraries.

Calibrating the sensors

Now, if your sensor has an adjustment pot, you may need to calibrate the sensors a little. As mentioned, these sensors turn the amount...
