Course Overview

Imagine the following scenario: you have a robot with a laser mounted on it. In order to be able to use the laser data (ej. to detect an obstacle), the robot needs to know WHERE that laser is mounted in the robot. If you don’t provide this information to the robot, when the laser detects that obstacle, how can the robot know where the object is? Is it in front of the robot? Or is it behind it?

Well, this relation between the different parts (frames) of a robot is what is handled by ROS TFs.

In this TF ROS 101 course, you will be able to understand how TF work by practicing in several hands-on exercises

This is a very poorly designed course. It has a lot of typos and instructions are hard to follow.
