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.

Setting up the ROS-2 workspace

A ROS workspace is a directory where we keep the ROS packages. As you saw in the preceding setup, you know that the build technique that's used in ROS-2 is colcon instead of catkin, which was used in ROS-1. The workspace layout is a bit different in ROS-2. Colcon does out of source builds and creates the following folders:

The build folder is where intermediate files are stored.
The install folder is where each package will be installed.
The log folder is where all the logging information is available.
The src folder is where the source code is placed.

Note that there is no devel folder like there is in ROS-1.

As the build steps were already explained and tried out while building the ROS-2 packages, let's quickly look at the commands that are needed to build any ROS-2 workspace.

Let's consider the ros2_examples_ws package for demonstration...
