ROS Robotics Projects - Second Edition

Overview of this book

Nowadays, heavy industrial robots placed in workcells are being replaced by new age robots called cobots, which don't need workcells. They are used in manufacturing, retail, banks, energy, and healthcare, among other domains. One of the major reasons for this rapid growth in the robotics market is the introduction of an open source robotics framework called the Robot Operating System (ROS). This book covers projects in the latest ROS distribution, ROS Melodic Morenia with Ubuntu Bionic (18.04). Starting with the fundamentals, this updated edition of ROS Robotics Projects introduces you to ROS-2 and helps you understand how it is different from ROS-1. You'll be able to model and build an industrial mobile manipulator in ROS and simulate it in Gazebo 9. You'll then gain insights into handling complex robot applications using state machines and working with multiple robots at a time. This ROS book also introduces you to new and popular hardware such as Nvidia's Jetson Nano, Asus Tinker Board, and Beaglebone Black, and allows you to explore interfacing with ROS. You'll learn as you build interesting ROS projects such as self-driving cars, making use of deep learning, reinforcement learning, and other key AI concepts. By the end of the book, you'll have gained the confidence to build interesting and intricate projects with ROS.

Introducing to scikit-learn

Until now, we have been discussing deep neural networks and some of their applications in robotics and image processing. Apart from neural networks, there are a lot of models available to classify data and make predictions. Generally, in machine learning, we can teach the model using supervised or unsupervised learning. In supervised learning, we train the model against a dataset, but in unsupervised, it discovers groups of related observations called clusters instead.

There are a lot of libraries available for working with other machine learning algorithms. We'll look at one such library called scikit-learn; we can use it to play with most of the standard machine learning algorithms and implement our own application. scikit-learn (http://scikit-learn.org/) is one of the most popular open source machine learning libraries for Python. It provides...
