Similar to the warning when . Remapping rules have two parts. The remapping does not seem to work. There's a chance this combination isn't expected to work, but I think it might be. I'm not sure if this is intended to work as I expect, but it seems reasonable to me. For example: If my service is on '/service' and my client-node is in a namespace called 'a' and therefore tries to connect to '/a/service'. You signed in with another tab or window. I've been trying to remap the /joint_states topic for 2 "ComposableNodes" in a dual-arm system. Already on GitHub? OK. At this point, this seems like a configuration issue somewhere.

The latter is destroyed shortly after controller is started. In general they work more like "dynamic reconfigure parameters" from ROS 1, in that they are node specific (no truly global parameters) and they are managed by the node (the node can refuse changes and parameters can only be read and changed while the node is running). So I don't think the remapping has taken effect. Already on GitHub? No luck. Don't ask me why. As you could see during this tutorial, it's really easy to remap a topic.

At this point, this seems like a configuration issue somewhere. In ROS 2, there are only one kind of parameters and they work differently. to your account. For example, to configure the talker node to publish to /wg/chatter instead of chatter: rosrun rospy_tutorials talker chatter:=/wg/chatter Don't ask me why. No luck. remap. Often the launch files from other included packages provide launch arguments to overwrite parameters, node names, namespaces, and sometimes topics. and in this instance running the launch file would start an action named "action_name" rather than "action_server_1".

Topic remapping does not work in namespaced component nodes. yeah I have checked carefully, here is my exact code: but 'ros2 action list' returns 'move_axis_to', additionally 'ros2 topic list' reveals that the topic name remap works so I am sure that the remap syntax is not wrong. this example works well for me, i am posting it even if it seems the same as yours: Edit: have you tried adding commas after each line like in my example ? Define custom messages in python package (ROS2), Incorrect Security Information - Docker GUI. That does work. To bring some closure to this, it works properly when the namespace of the component container is removed. Is there (already) a way in Ros 2 to remap services in a launch file? Remapping arguments can be passed to any node and use the syntax name:=new_name. Remappings are applied after the namespacing. edit. The above command does not change the node name, but I would expect the output of ros2 node list to contain /foo. Remapping topics in gazebo, not working? Remapping a ROS topic can be very handy when you don't have full control over which node is publishing on what, and which node is subscribing from what. 1 comment Bjoernolav commented on Aug 11 edited Operating System: Ubuntu 22.04 Installation type: Docker container based on ros:humble It worked fine with @clalancette 's simple examples whether there was a component container namespace or not.
