rviz2 not receiving map (tutorial example)

[PVBrodersen]

I have been following along with this tutorial, and gotten to the section regarding visualization of costmaps. However, at this point, I run into 2 issues:

1) Rviz2 not receiving costmaps As the section suggests, rviz2 is unable to receive any maps from the respective costmaps topics, even though I can confirm that data is published using topic echo:

" ros2 topic echo /global_costmap/costmap header: stamp: sec: 1702383893 nanosec: 146251016 frame_id: map info: map_load_time: sec: 0 nanosec: 0 resolution: 0.05000000074505806 width: 44 height: 36 origin: position: x: -1.1546438506086725 y: -0.6746192693179669 z: 0.0 orientation: x: 0.0 y: 0.0 z: 0.0 w: 1.0 "

2) Filter dropping messages

After running "display.launch.py" it opens rviz2 and gazebo as expected, but after sometime the terminal starts outputting the following:

[rviz2-5] [INFO] [1702383769.153491354] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383754.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383770.177533838] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383755.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383772.160809140] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383757.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383774.177586825] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383758.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383775.168952119] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383759.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383776.161561609] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383761.146 for reason 'discarding message because the queue is full' [rviz2-5] [INFO] [1702383777.153654436] [rviz2]: Message Filter dropping message: frame 'map' at time 1702383763.146 for reason 'discarding message because the queue is full'

Which is also represented by a drifting map frame in rviz i.e. the frame starts moving up the z-axis.

Any suggestions as to what this might be caused by?

To add to this post: I got to the point where I decided to simply clone the repo, but still run into the same issues.

@PVBrodersen hi!

I'm facing the same problem too. which ros2 distro are you using?

[YinpeiDai]

Any update on this?

[arad2456]

I am also having this problem. I use humble

[jmk9]

I also can't solve this problem.

@PVBrodersen hi!

I'm facing the same problem too. which ros2 distro are you using?

I am running ROS2 Humble on Ubuntu 22.04 LTS

However, after reading into this issue a bit more, I suspect that it may be due to the fact that the default parameter of navigation.launch.py do NOT contain the parameters specified for nav2_costmap_2d as otherwise stated in the guide. I will keep you posted if modifying this changes anything.

Sadly a reconfiguration did not seem to fix the issue

OK, after looking around, I have found that this issue is the same as described in another thread on the github: https://github.com/ros-planning/navigation2_tutorials/issues/64

Essentially, the joint state publisher needs to be setup with the sim_time parameter.

After doing this, and launching everything from the same launch file I have gotten my solution to work.

@PVBrodersen Hello, I still facing this problem...but I can't fix it even though I tried your suggestion about 'sim_time'. Can you show me your full code repo about this tutorial? Thanks a lot.

Ok... Now I already been success! The main reason is also about 'use_sim_time', but I modified use_sim_time's value of global_costmap by run command 'rqt'. You just need to click a √, then all thing is right!

and then I find a strange thing that is the default value of 'use_sim_time' is False in the launch file 'navigation_launch.py'... So all things don't work properly even though you see the param file 'nav2_params.yaml' is right. Anyway, I fixed this last night. You can use this command:

ros2 launch nav2_bringup navigation_launch.py use_sim_time:=True

Okay, everything will be fine!

can anyone share there updated package/repo which is working?

Hello, Im facing the "no map received" on rviz .. I am using ROS1 noetic and Gazebo 11 There is no data being published in the /map topic however this topic exists What should I do?
