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.

Simulating the application

Now, everything is set for the final demonstration. We have a robot base that can move autonomously in the environment and the arm can move to any location that we define it to go to. So, to run our application, we need to perform the following steps:

  1. Map and save the environment.
  2. Choose the points on the environment.
  3. Add the points to our library.
  4. Define the respective states.
  5. Complete the state machine.

Let's look at these steps in detail.

Mapping and saving the environment

Follow these steps to map and save the environment:

  1. The first step is to make the robot understand the environment. For this, we use an open source mapping technique we saw in the Making our robot arm intelligent section...
