Thanks, this works for me, so does this mean we cannot use code(not the code with command) to load parameter file at run

Thanks for your reply, I don't use ros_control before, and I'm not going to use the open source package in this system.

What is the preferable way to share states among multiple nodes in ROS? Hi all, I am developing a robot software system

This doesnot work for me, I test it on ros2 foxy and ubuntu20.04

Have you fixed this problem? I have encountered the same problem in ros2 foxy.

Hi,

After I read through the navigation2 document in navigation2 document, I find that the features and source code between different distribution has much difference. For example, navigation2 eloquent add serveral new packages and plugins and has a change on architectural design compared to dashing.

And from my test, rviz2 in ROS2 eloquent support message filters now, but ROS2 dashing still don't support this feature.

My confusion here is from the ROS2 index website, the ROS2 dashing will be supported until May 2021, but ROS2 eloquent will end its life on November 2020, why the new features or functions is not added on the ROS2 LTS distribution? Though ROS2 foxy LTS is released, but because the support packages is still limited and it's running on Ubuntu20.04 which is still not supported for our robot.

Hope someone could ease my confusion, Thanks.

Thanks for your detail explanation, I got better understanding about it now.

Yes, I think, from the TF tree in rviz there is no error, and I don't know how to show tf tree in ROS2

rviz2 could not display laser scan data when the fix frame is set to odom Hi, I'm working on ubuntu18.04 and ROS2 dashi

I have finally figured out where the problem is. Just check Unreliable option and the rviz2 can show laser scan points.

@Humpelstilzchen Yes, you're right, it's the pdist_scale parameter which makes this difference, but what's strange is th
