Python Robotics Projects

By: Prof. Diwakar Vaish

Overview of this book

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.

Controlling the vehicle by Bluetooth


Had some fun trying those combinations? Now is the time that we take this journey a step ahead and see what else is possible. We have all played with remote-controlled cars and I'm sure everyone will have had fun with those zippy little toys. We are going to do something similar but in a much more sophisticated way.

We all are aware of Bluetooth: this is one of the best ways to communicate with devices in close proximity. Bluetooth communication is a medium data rate, low power communication method. This is almost omnipresent in mobile devices, hence it is an ideal way to start. What we will be doing in this chapter is controlling the car via your mobile phone using Bluetooth. Now let's see how we can do it.

The first thing we want to do is pair up the smartphone to the robotic vehicle, and to do so we need to open the terminal on Raspberry Pi and perform the following steps:

  1. Type in the command ~ $ bluetoothctl; this is a Bluetooth agent which allows two...
