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.

Chapter 6: Using the ROS MoveIt! and Navigation Stack

In the previous chapters, we have been discussing the design and simulation of a robotic arm and a mobile robot. We controlled each joint of the robotic arm in Gazebo using the Robot Operating System (ROS) controller and moved the mobile robot inside Gazebo using the teleop node.

In this chapter, we are going to address the motion-planning problem. Moving a robot by directly controlling its joints manually might be a difficult task, especially if we want to add position or velocity constraints to the robot's motion. Similarly, driving a mobile robot and avoiding obstacles requires the planning of a path. For this reason, we will solve these problems using the ROS MoveIt! and Navigation stack.

MoveIt! represents a set of packages and tools for doing mobile manipulation in ROS. The official web page (http://moveit.ros.org/) contains documentation, a list of robots using MoveIt!, and various examples to demonstrate pick...
