How to Launch RViz and RQt in ROS

RobotModel

Up until now we have been interacting with ROS via the Linux terminal. ROS also has some really cool graphical user interface (GUI) tools that enable you to interact with ROS in a more visual way than we have done so far. Two of these tools are rviz and rqt.

  • rviz is a 3D visualizer for ROS
  • rqt is a ROS visualization tool based on Qt, a free and open-source widget toolkit for creating GUIs.

In this tutorial, I’ll show you how to set up both of these tools.
