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

Gmapping and localization in Chefbot


After launching the ROS driver, we can teleop the robot using keyboard teleop. We can use the following command to start keyboard teleoperation:

$ roslaunch chefbot_bringup keyboard_teleop.launch

If we want to map the robot environment, we can start the gmapping launch file like we did in the simulation:

$ roslaunch chefbot_bringup gmapping_demo.launch

You can visualize the map building in Rviz using the following command:

$ roslaunch chefbot_bringup view_navigation.launch

You can build the map by teleoperating the robot around the room. After mapping, save the map as we did in the simulation:

$ rosrun map_server map_saver -f ~/test_map

After getting the map, launch AMCL nodes to perform final navigation. You have to restart all the launch files and start again.

Let's look at the commands to launch the AMCL nodes.

First, start the ROS driver nodes using the following command:

$ roslaunch chefbot_bringup robot_standalone.launch

Now start the AMCL nodes:
