Course overview

Imagine the following scenario: you have a robot drone with a camera that has to follow another subject to fil it correctly. How do you tell the robot where to point the camera? How to follow the subject and at which distance? And all of this dynamically? What is the distance from the camera to the subject? Is the orientation okay?

ROS2 TFs handle this relation between the different parts (frames) of a robot.

In this TF ROS2 course, you will be able to understand how TF works by practicing in several hands-on exercises

What You Will Learn

  • How to Visualize TFs in ROS2
  • How to Publish & Subscribe to TF data
  • Understanding Transformations & Frames
  • Common TF Command-line Tools (tf_echo, view_frames…)
  • Understanding Static Transform Publisher

Multiple things did not work in this simulation. There was no .rviz file like it had listed so we manually had to load the rviz components. the camera image in units 1 and 2 did not work. Could not tell why. In unit 3, the 'unicycle' package (that was premade) was saved as 'uniclicle' so that did not work out of the box and required troubleshooting as well
