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.

Motion planning of a robot in RViz using the MoveIt! configuration package

MoveIt! provides an RViz plugin that allows developers to set the planning problem. From this plugin, the desired pose of the manipulator can be set, and a motion trajectory can be generated to test MoveIt! planning capabilities. To launch this plugin along with the robot model, we can directly use the MoveIt! launch files included in the MoveIt! configuration package. This package consists of configuration files and launch files to start motion planning in RViz. There is a demo launch file in the package to explore all the package's functionalities.

Here is the command to invoke the demo launch file:

roslaunch seven_dof_arm_config demo.launch  

If everything works fine, we will get the following screen of RViz being loaded with the MotionPlanning plugin provided by MoveIt!:

As you can see, from this plugin you can configure...
