Learn Robotics Programming

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.

Attaching line sensors to the robot and Raspberry Pi

In this section, we will get to know the parts we are about to use and then mount them on the robot, wiring up to the Pi.

What are optical line sensors?

There are a few types of sensor that can be used. One type is known as hall sensors, which can detect magnetic strips or current carrying cables. The other type are optical sensors. Basic optical line sensing bounces infrared light off of whatever is below the robot. It then detects the intensity of the reflected light.

These send a data value depending on this. The sensor we will use turns this intensity into a binary, 1 or 0, value by seeing if the detected light passes a threshold. The following photo shows the sensors...
