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.

Driving a specific distance

For this behavior, we'll use the PI Controller again, and incorporate the distance measurements into our encoder object. We will calculate how many ticks we want the left wheel to have turned for a given distance, and then use this instead of a timeout component.

Refactoring unit conversions into the EncoderCounter class

We'll want the conversions for our encoders in the the EncoderCounter class so that we can use them in these behaviors. Open up your encoder_counter.py class. First, we need the math import:

from gpiozero import DigitalInputDevice
import math
...

At the top of the class, add ticks_to_mm_const as a class variable (not an instance variable) so that we can use it without any...
