I also reproduce this in another way. First fire up rqt and start Dynamic Reconfigure plugin. Then fire up a node lets s

rqt --clear-config fixed the issue somehow if you use rqt_reconfigure with gazebo it goes to that state again. To reprod

I am trying to change the QoS settings to use the shared memory but I got the following error when tying to run a node. It says the OpenSpliceDDS is not running in shared memory mode but I started it by ospl start and says ospl start Domain with name ospl_shmem_ddsi with id 0 is already running, ignoring command if I try to start it again. So I am wondering if it is possible to use shared memory configuration with ROS2.

rcutils_reset_error() should be called after error handling to avoid this.

My question is if ros2 has support for Adlink Opensplice lib and what extend?

Well yes it works but what we found is it has some performance issues and higher resource usage (especially CPU) than t

Thanks for the answer from the latest commits to the infrastructure I see that they are changing the definition of Tier

You can pause the physic engine by writing "rosservice call gazebo/pause_physics" on the terminal. look at gazebo tutorials for other options.

Hi ZdenekM,I am trying to create urdf of the robotic arm which driven by dynamizel servos so what's the PID gain that you have used.Your urdf file is removed on the link above.
