Introduction

If you're interested in robotics, you've probably come across RVIZ. RVIZ is a powerful visualization tool that allows you to see and interact with 3D models of your robot, sensor data, and more. However, if you're new to RVIZ, it can be a bit overwhelming. In this tutorial, we'll cover the basics of RVIZ and show you how to get started.

What is RVIZ?

RVIZ is a 3D visualization tool for ROS (Robot Operating System). It allows you to view sensor data, robot models, and other data in a 3D environment. RVIZ is an essential tool for debugging, testing, and visualizing your robotics projects.

Installing RVIZ

Before we can use RVIZ, we need to install it. If you're using ROS, RVIZ should already be installed. To check if RVIZ is installed, open a terminal and type the following command: rosrun rviz rviz If RVIZ opens, it's installed. If not, you can install it by running the following command: sudo apt-get install ros-melodic-rviz

Starting RVIZ

To start RVIZ, open a terminal and type the following command: rosrun rviz rviz This should open the RVIZ window. RVIZ has a default configuration that includes a 3D view, a panel for displaying sensor data, and a panel for displaying robot models.

Using RVIZ

The RVIZ interface can be a bit overwhelming at first, but it's actually quite straightforward. The left-hand side of the window contains a list of available displays, such as 3D objects, sensor data, and robot models. The right-hand side of the window contains panels that display data related to the selected display.

Adding Displays

To add a display, click on the "Add" button in the Displays panel. This will open a menu of available displays. Select the display you want to add, and it will be added to the display list. You can then configure the display by clicking on its name in the display list.

Configuring Displays

To configure a display, click on its name in the display list. This will open a panel with options for configuring the display. For example, if you're displaying sensor data, you can configure the color, size, and shape of the data points.

Interacting with Displays

You can interact with displays in RVIZ using your mouse. To rotate the 3D view, click and drag with the right mouse button. To pan the view, click and drag with the middle mouse button. To zoom in and out, scroll with the mouse wheel.

Saving Configurations

If you've configured RVIZ to your liking, you can save your configuration by clicking on the "File" menu and selecting "Save Config As...". This will save your RVIZ configuration to a file that you can load later.

Conclusion

RVIZ is an essential tool for anyone working with robotics. With RVIZ, you can visualize sensor data, robot models, and more in a 3D environment. By following this tutorial, you should now have a basic understanding of how to use RVIZ. Experiment with different displays and configurations to get the most out of this powerful tool.
