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 using the move_group C++ interface

In Chapter 6, Using the ROS MoveIt! and Navigation Stack, we discussed how to interact with a robot arm and how to plan its path using the MoveIt! ROS Visualization (RViz) motion planning plugin. In this section, we will see how to program the robot motion using the move_group C++ APIs. Motion planning using RViz can also be done programmatically through the move_group C++ APIs.

The first step to start working with C++ APIs is to create another ROS package that has the MoveIt! packages as dependencies. We can create this same package using the following command:

catkin_create_pkg seven_dof_arm_test catkin cmake_modules interactive_markers moveit_core moveit_ros_perception moveit_ros_planning_interface pluginlib roscpp std_msgs

Let's start using the move_group API to execute planned trajectories.

Motion planning a random path using MoveIt! C++ APIs

The first example that we are going to see is a random motion plan...
