Feb 4, 2021 · Try using the set_pose button at the top of the RVIZ GUI to give your robot an initial location. You have to realize that your robot doesn't magically know things about its position in the world, you must be very deliberate to tell it those things

According to here, map_assembler subscribes to rtabmap_ros/MapData I see the following mapData related topics: rostopic list | grep -i MapData /mapData /rtabmap/mapData but not rtabmap_ros/MapData I tried running map_assembler from the command line as stand alone.

Jun 9, 2020 · There is a transform from map -> odom -> base_link -> to the rest of the bot. It's also posting a pose, because you can set a goal on the map, and the bot is moving towards it. The global costmap is online, just the local costmap is not showing up in rviz saying no transform from odom -> to map. I will add a picture later on.

Jun 17, 2022 · I want to make dynamic updates to my map. I have an object detection pipeline ready which gives me 3D coordinates of objects in the environment and with that, I can check if the position of any object has been changed. I want to reflect that change in my map and basically want to update the occupancy grid. What can be the best way to do that?

So my problem is that I have a relatively big map 2144 by 2528 pixels and this leads to big latency in the global costmap update it usually misses the desired rate of 1.0 HZ. I realize that reducing the resolution might be a solution but I do not want to reduce the accuracy of the map also.

Verify that RViz is receiving your published grid map messages by using tools such as rostopic echo or rostopic hz to verify if the grid_map topic is publishing what should be expected messages. By considering these points, you should be able to quickly recognize and address issues related to visualizing grid maps in RViz.

Apr 30, 2014 · right now I have achieved that I initialized the map and visualized it in rviz. It is fairly simple as I just set height, width, resolution and placed all zeros in .data. My next task should be use the sensor data being published and generate a map. and here I am stuck as I cannot find some appropriate tutorials.

I installed cartographer ros from the official documentation here, and I am running ubuntu 16.04 with ROS kinetic. If I can understand how map->base_link transform is generated I should be able to understand reason behind the issues I am getting

After replaying all the stored message in the robag I stopped playing from the bag and instead started the map_server as follows: rosun map_sever map_saver. The map_server then informs me that it is Waiting for the map. To get a better sense of why the map server waits, I printed the debug messages from both map_server and gmapping. The server ...

The map_server is just saving the map part, it has no visibility of any other messages being passed around ROS at the time, which includes your marker messages. Hope this helps. Asked by PeteBlackerThe3rd on 2018-11-27 07:13:25 UTC
