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.

The MoveIt! architecture

Before using MoveIt! in our ROS system, you have to install it. The installation procedure is very simple and is just a single command. Using the following commands, we install the MoveIt! core, a set of plugins and planners for ROS Noetic:

sudo apt-get install ros-noetic-moveit ros-noetic-moveit-plugins ros-noetic-moveit-planners

Let's start with MoveIt! by discussing its architecture. Understanding the architecture of MoveIt! helps to program and interface the robot with MoveIt!. We will quickly go through the architecture and the important concepts of MoveIt!, and start interfacing with and programming our robots.

Here is an overview of the MoveIt! architecture:

The move_group node

We can say that move_group is the heart of MoveIt!, as this node acts as an...
