I moded on the lesson, in 2.2 QoS: Quality of Service
typing:
rviz2 -d /home/user/ros2_ws/src/box_bot/box_bot_description/rviz/3_box_bot.rviz

Hi I solve with
to start gazebo with
user:/home/simulations$ cd ros2_sims_ws/
user:/home/simulations/ros2_sims_ws$ source install/setup.bash
user:/home/simulations/ros2_sims_ws$ ros2 launch box_bot_gazebo main.launch.xml

and to start rviz2 options file:
user:/home/simulations/ros2_sims_ws/src/box_bot/box_bot_description/rviz$ rviz2 -d box_bot.rviz

Unfortunately, I do not see the topics with:
user:/home/simulations/ros2_sims_ws$ ros2 topic list
/parameter_events
/rosout

Best,
Salvatore

@saxosun

rviz2 -d /home/user/ros2_ws/src/box_bot/box_bot_description/rviz/3_box_bot.rviz

I find this error:

Regarding the location of the rviz file, let me capture this bug for review by the team.

@saxosun

Unfortunately, I do not see the topics with:
user:/home/simulations/ros2_sims_ws$ ros2 topic list
/parameter_events
/rosout

Were you able to see the topics when you sourced as indicated in the notebook?

Response from @saxosun through e-mail:

Not completely. I saw the box bot robot in Gazebo, I saw it in RViz with lasers and deep camera, but I do not see any topics using ros2 topic list

Also it seems to me that DDS course in not suitable for the remote users, am I right? thanks

Hi @saxosun,

I see you are facing some problems in the DDS course.

This course is indeed not ready to be followed online. It was created for an In-Person Intensive Training in Barcelona, where at least 20 Raspberry PI were configured for the training, but are not running right now (after the in-person training has finished).

Let’s see what @rtellez says, but I suppose one of the two things will happen:

1. The course will be disabled because it is not ready to be followed online
2. The course will be modified to be easily followed online.

I see that the second is better for you and many other members of The Construct.

Ricardo will come up with a solution for this next week, after discussing it with @roalgoal.
