Since ROS Fuerte, the rx applications or tools are deprecated, and we should instead use the rqt nodes. They are basically the same, and only a few of them incorporate small updates, bug fixes, and new features. The following table shows the equivalences for the tools shown in this chapter (the ROS hydro rqt tool and the one it replaces from previous ROS distributions):

In ROS hydro, there are even more standalone plugins, such as a shell (rqt_shell), a topic publisher (rqt_publisher), a message type viewer (rqt_msg), and much more (the most important ones have been covered in this chapter). Even rqt_viz is a plugin, which replaces rviz, and can also be integrated into the new rqt_gui interface. We can run this GUI and add and arrange several plugins manually on the window, as it has been seen in several examples in this chapter:

$ rosrun rqt_gui rqt_gui
