This is the fourth volume of the successful series Robot Operating Systems: The Complete Reference, providing a comprehensive
overview of robot operating systems (ROS), which is currently the main development framework for robotics applications, as
well as the latest trends and contributed systems. The book is divided into four parts: Part 1 features two papers on navigation,
discussing SLAM and path planning. Part 2 focuses on the integration of ROS into quadcopters and their control. Part 3 then
discusses two emerging applications for robotics: cloud robotics, and video stabilization. Part 4 presents tools developed
for ROS; the first is a practical alternative to the roslaunch system, and the second is related to penetration testing. This
book is a valuable resource for ROS users and wanting to learn more about ROS capabilities and features.
