Overview of this book

ROS is a robust robotics framework that works regardless of hardware architecture or hardware origin. It standardizes most layers of robotics functionality from device drivers to process control and message passing to software package management. But apart from just plain functionality, ROS is a great platform to learn about robotics itself and to simulate, as well as actually build, your first robots. This does not mean that ROS is a platform for students and other beginners; on the contrary, ROS is used all over the robotics industry to implement flying, walking and diving robots, yet implementation is always straightforward, and never dependent on the hardware itself. ROS Robotics has been the standard introduction to ROS for potential professionals and hobbyists alike since the original edition came out; the second edition adds a gradual introduction to all the goodness available with the Kinetic Kame release. By providing you with step-by-step examples including manipulator arms and flying robots, the authors introduce you to the new features. The book is intensely practical, with space given to theory only when absolutely necessary. By the end of this book, you will have hands-on experience on controlling robots with the best possible framework.

Chapter 1. Getting Started with ROS

In this chapter, we will introduce the Robot Operating System (ROS), which is a collection of software packages to aid researchers and developers using robotic systems. After we discuss the instructions to install ROS on your computer system using the Ubuntu operating system, the ROS architecture and many of its components are discussed. This will aid you in understanding the use of ROS to develop software for robotic applications.

ROS will be introduced in terms of its elements and their functions. An understanding of the ROS vocabulary is necessary to become proficient in using ROS to create programs for the control of real or simulated robots as well as devices, such as cameras.

To make the discussion more concrete, the turtlesim simulator will be presented with various examples of the ROS command usage. This simulator is part of ROS and it provides an excellent introduction to the capabilities of ROS.

In this chapter, we will cover the following topics:

  • What ROS is and which robots use ROS
  • How to install and launch ROS on your computer
  • How to navigate the ROS directories
  • An introduction to ROS packages, nodes, and topics
  • Examples of useful ROS commands
  • How to use ROS commands with the turtlesim simulator
