Brief introduction and use of rviz

rviz is a 3D visualization platform in ROS. On one hand, it can realize the graphical display of external information, and on the other hand, it can also release control information to an object through rviz, realizing the monitoring and control of a robot.

1 Installation of rviz and the introduction to its interface

When installing ros, if you perform a complete installation, rviz is already installed, and you may try to run it directly; if it is not fully installed, you may install rviz separately:

# Ubuntu16.04
sudo apt-get install ros-kinetic-rviz
# Ubuntu18.04
sudo apt-get install ros-melodic-rviz
# Ubuntu20.04
sudo apt-get install ros-noetic-rviz

After the installation is complete, open a new terminal (shortcut key: Ctrl+Alt+T) and enter the following command:


Then open a new terminal (shortcut key: Ctrl+Alt+T) and input the following command to open rviz.

rosrun rviz rviz
# or

Open rviz, and the following interface will be displayed:

1.1 Introduction of all areas

  • There is a list of monitors on the left. The monitor is a device that draws something in a 3D world and may have some options available in the display list.
  • On the top is a toolbar, which allows the user to use various function buttons to select tools with multiple functions.
  • The middle part is the 3D view: It is a main screen where various data can be viewed in three dimensions. The background color, fixed frame, grid, etc. of the 3D view can be set in detail in the Global Options and Grid items displayed on the left.
  • Below is the time display area, including system time and ROS time.
  • The right side is the observation angle setting area where different observation angles can be set.

We only give a rough introduction in this part. If you want to know more details, go to User Guide.

1.2 Simple use

Start using launch file

This example is built on what you have already done Environment building and you have successfully copied the company's code from GitHub to your virtual machine.

Open a new terminal (shortcut key: Ctrl+Alt+T)

Input the command to configure the ROS environment.

cd ~/catkin_ws/
source devel/setup.bash

Input again:

  • mycobot 280-M5 version:
roslaunch mycobot_280 test.launch
  • mycobot 280-Pi version:
roslaunch mycobot_280pi test.launch
  • mycobot 280-JetsonNano version:
roslaunch mycobot_280jn test.launch

Open rviz, and then you will obtain the following result:
