ROS Robotics Projects

Overview of this book

Robot Operating System is one of the most widely used software frameworks for robotic research and for companies to model, simulate, and prototype robots. Applying your knowledge of ROS to actual robotics is much more difficult than people realize, but this title will give you what you need to create your own robotics in no time! This book is packed with over 14 ROS robotics projects that can be prototyped without requiring a lot of hardware. The book starts with an introduction of ROS and its installation procedure. After discussing the basics, you’ll be taken through great projects, such as building a self-driving car, an autonomous mobile robot, and image recognition using deep learning and ROS. You can find ROS robotics applications for beginner, intermediate, and expert levels inside! This book will be the perfect companion for a robotics enthusiast who really wants to do something big in the field.

Preface

Simulating IMU on Gazebo


Similar to GPS, we can start the IMU simulation using the following command:

$ roslaunch sensor_sim_gazebo imu.launch

You will get orientation values, linear acceleration, and angular velocity from this plugin. After launching this file, you can list out the topics published by the imu plugin. Here is the list of topics published by this plugin:

Figure 22: List of topics published from the imu ROS plugin

We can check out the /imu topic by echoing the topic. You can find orientation, linear acceleration, and angular velocity data from this topic. The values are shown here:

Figure 23: Data from the /imu topic

If you look at the IMU plugin definition code from sensor_sim_gazebo/urdf/imu.xacro, you can find the name of the plugin and its parameters.

The name of the plugin is mentioned in the following code snippet:

      <gazebo> 
        <plugin name="imu_plugin" filename="libgazebo_ros_imu.so"> 
          <alwaysOn>true</alwaysOn> &...
