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.

Generating a MoveIt! configuration package using the Setup Assistant tool

The MoveIt! Setup Assistant tool is a GUI for configuring any robot to MoveIt!. This tool basically generates SRDF, configuration files, launch files, and scripts generated from the robot URDF model, which is required to configure the move_group node.

The SRDF file contains details about the arm joints, end effector joints, virtual joints, and the collision-link pairs that are configured during the MoveIt! configuration process using the Setup Assistant tool.

The configuration file contains details about the kinematic solvers, joint limits, controllers, and so on that are also configured and saved during the configuration process.

Using the generated configuration package of the robot, we can work with motion planning in RViz without the presence of a real robot or simulation interface.

Let's start the configuration wizard, and we can see the step-by-step procedure to build the configuration...
