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.

Understanding the MoveIt configuration of a Universal Robots arm

The MoveIt configuration for Universal Robots arms is in the config directory of each moveit_config package (ur10_moveit_config for the UR-10 configuration).

Here is the default content of the controller.yaml file of UR-10:

controller_list: 
  - name: "" 
    action_ns: follow_joint_trajectory 
    type: FollowJointTrajectory 
    joints: 
      - shoulder_pan_joint 
      - shoulder_lift_joint 
      - elbow_joint 
      - wrist_1_joint 
      - wrist_2_joint 
      - wrist_3_joint 

To properly connect the MoveIt side, we must set the correct action_ns element. Let's change this file in the following way:

controller_list: 
  - name: ...
