…ods of move_group_interface - Reimplemented getPlannerParams, setPlannerParams, getInterfaceDescription, getInterfaceDescriptions, plan, execute, move and computeCartesianPath methods of move_group_interface using rclcpp's own api - Removed callback_thread_
…rmw_wait issues of rmw_zenoh - Changed move_group server's executor as SingleThreadedExecutor - Added event_topic_subsciber to different executor

We have modified this part due to the fact that rmw_wait function of rmw_zenoh still has some problems. We must use SingleThreadedExecutor at the moment.

I added this callback group to private_executor that also spins control_manager node so that event_topic_subscriber receives callback to stop trajectory execution. Shortly, it seems MultiThreadedExecutor in MoveIt's default implementation is just for spinning this subscription.

It's not necessary anymore. rmw_zenoh is able to run with MultiThreadedExecutor now . Closing. |

Description
I made a few modifications for MoveIt to be able to run with rmw_zenoh middleware implementation. This is experimental PR and should not be merged. It seems this modifications works well with rmw_zenoh. We have actually just changed below (see my reviews) parts. I also added this PR's commits. By the way i don't know how these changes affect MoveIt execution flow. I am still investigating.
