Hello, I have completed the ROS2 Navigation course and would like to thank the developers as it was very informative and helpful. However, I would just like to point out a slight mistake in the notebook that should help prevent future visitors from making this error:
I believe that in tool properties, it should be named
/tb3_0/goal_pose and NOT /tb3_0/goalpose
Likewise for the tb3_1 robot model
That is the change I had to make in order to get it to work.
Thank you
