Mastering ROS for Robotics Programming, Third edition - Third Edition

By: Lentin Joseph, Jonathan Cacace

Overview of this book

The Robot Operating System (ROS) is a software framework used for programming complex robots. ROS enables you to develop software for building complex robots without writing code from scratch, saving valuable development time. Mastering ROS for Robotics Programming provides complete coverage of the advanced concepts using easy-to-understand, practical examples and step-by-step explanations of essential concepts that you can apply to your ROS robotics projects. The book begins by helping you get to grips with the basic concepts necessary for programming robots with ROS. You'll then discover how to develop a robot simulation, as well as an actual robot, and understand how to apply high-level capabilities such as navigation and manipulation from scratch. As you advance, you'll learn how to create ROS controllers and plugins and explore ROS's industrial applications and how it interacts with aerial robots. Finally, you'll discover best practices and methods for working with ROS efficiently. By the end of this ROS book, you'll have learned how to create various applications in ROS and build your first ROS robot.

Getting started with ROS and Simulink

In the previous sections, we discussed how to interact with ROS using MATLAB. In this section, we are going to use another powerful tool of MATLAB: Simulink. Simulink is a graphical programming environment for modeling, simulating, and analyzing dynamical systems. We can use Simulink to create a model of a system and simulate its behavior over time. In this section, we will start creating our first simple system from the ROS framework. We will also discuss how to develop a ROS application using Simulink.

Creating a wave signal integrator in Simulink

To model a new system, let's start by opening Simulink. We can open it by typing the following command in the Command Window:

>> Simulink

Then, you should choose to create a new blank model. To create a new system, we must import the desired Simulink blocks that will compose it. These blocks can be directly dragged and dropped into the model window from the Library Browser. To...
