I want to have my robot load a new map if it moves off of an existing map into another space. I know how to use the map_server node to load a map when it is started up, but can I then tell it to load a different map without having to stop and re-start the node? What is the best way to do this? I looked at the map_server wiki and I don't see any service for 'set_map' or 'load_map' or anything like that.

Can Gazebo do 2D 'flatland' only simulation I'm looking at various 2D simulators (Flatland and STDR) but am already quit

This worked, sorry I should have closed it before, closing now with accepted answer.

Closing this question as duplicate, I think the link above provides the details necessary.

As of PR #1303, Navigation2 supports this.

Is there an example of setting parameters on another node using rclpy? I can't find one.

Are you sure the tinyxml install worked completely? Did you run 'apt search tinyxml' to make sure the package is there?

We have split move_base up into it's base components in ROS2 and are using behavior trees to drive the components. This

I had the same issue, and even though I could run the 'ros2 multicast send; and receive both directions, topics and node

Was this resolved? I am having the same issue, and I ran the multicast tool and that works. Not sure what else to try.

@lucasw - thanks I will try this and post back later

@lucasw - did you get arguments to work? I can't seem to get them passed through to an included launch file either

ROS2 - rclpy set parameter example? Is there an example of setting parameters on another node using rclpy? I can't find

@william - OK, I see the difference now. I was thinking getPath() was for the prefix, not the share location.

I'm using ament_index_cpp::get_package_prefix("packagename"), which returns the same as 'ros2 pkg prefix <packagename

Do you have any working examples of using it with AMCL? If so, that may help me to debug my issue.

The Turtlebot navigation package is based on the overall ROS navigation package, and I think that is what you really want. Read this page: http://wiki.ros.org/navigation and try tutorial #18. Make sure you have components for your sensors and actuators, you may have to write those yourself.

Do you have a kobuki? What is the base type of your robot? If it is a kobuki base, you can look at the launch files for the turtlebot and find the kobuki launch files for that portion of it. If you are not you will have to start from scratch and build your own.

Do you have an existing turtlebot to run as a reference? If so, you could run the turtlebot and do an rqt_graph to see all the running nodes & nodelets, then use that as your reference guide for how it works.

Yes, it is possible to use the Eclipse CDT. I am using it myself. You can import the project like any other C++ project but you need to change the C++ build settings to use catkin_make (catkin_make --pkg <your package="">) and your build directory to your catkin_ws directory.

I'm publishing an initialpose for my robot and using AMCL to do the localization. As part of the PoseWithCovarianceStamped msg type, I supply a 6x6 covariance matrix. For the X and Y covariance I am using a value of the confidence level in meters sq (5 meters sq), but I don't know what value I should be using for the Yaw covariance. How do I estimate that?
