ROS Developers LIVE-Class #24: How to create basic markers in ROS Rviz

Written by Ricardo Tellez

In this ROS LIVE-Class we’re going to learn how to create a marker to be displayed in ROS Rviz. Markers are special graphics that we can use in Rviz to display data generated by the robot. For example, we can create a marker that shows a person figure at the proper distance of the robot when the robot detects a person. By using markers, we can debug and understand better what the robot program is doing. Markers are basic tools for robot program debug!

We will see:

  •  How to get the information we want to display from a ROS program
  • How to create a custom marker that contains that information
  •  How to display the marker on the Rviz
  •  How to build a mesh marker and show it on Rviz

 

Every Tuesday at 18:00 CET/CEST.

This is a LIVE Class on how to develop with ROS. In Live Classes you practice with me at the same time that I explain, with the provided free ROS material.

IMPORTANT: Remember to be on time for the class because at the beginning of the class we will share the code with the attendants.

IMPORTANT 2: in order to start practicing quickly, we are using the ROS Development Studio for doing the practice. You will need a free account to attend the class. Go to http://rds.theconstructsim.com and create an account prior to the class.

5 Mistakes Robotics & ROS Teachers Make

Last week, a colleague of mine asked me for advice on how to teach ROS at university because she is going to start delivering a ROS class next month. Then I decided to record this video with 5 mistakes I have made in the past while teaching ROS at the university. I hope that this video is useful for you and helps you avoid the mistakes that I made so you can start delivering ROS classes smoothly.
