Hi. If you are publishing a point cloud topic, you can use the costmap_2d package. There you can understand more how t

I am setting both sensors as relative. Do I always need an absolute sensor to work with "initial_state" parameter?

I am setting both sensors as relative. Do I always need an absolute sensor?

Hello,

I am working with the robot_localization, filtering two odometry data.

Both of them start at (0,0,0), but I would like to start at (x,y,0).

I am using the initial_state parameter, but the topic keeps publishing the starting pose in (0,0,0).

Which are the possible problems?

I am setting the parameter on my yaml file only:

I am not sure if it is something you were looking for, but I have found out two packages on GitHub that uses LaserScan t

You may use the map_server node at your launch file. Do not forget to upload the.yaml file. Something like this. &

That is a good option. tf_remap can handle it temporally.

I am using Kinetic and Ubuntu 16.04.6 LTS, I am trying to upload a map file for map_server and use it for navigation and amcl localization, but it is really big, 25500 x 5300 pixels (.pgm). The map_server is not starting and shows this message:

[ERROR] [1556905481.419883442]: failed to open image file "/home/dev/src/robot/navigation/maps/bigger_map.pgm": Out of memory

Is possible to use a map with a big number of pixels or I need to reduce the number of pixels to work well? Is it depends on computer memory RAM?

I have tried to use in .png file format, but the message was the same.

You may use Rviz to check your map topic that is created.

You may wait a little bit because the robot needs to create the map, while moves around the space. Try to run the map_sa
