follow joint trajectory action

[MattiaDeiRossi]

Hi all,

is there anyone that has tried to use a server action on ros2 to communicate with client action on ros1?

I'm trying to use ros2_control framework with follow joint trajectory action server. I would connect to the same action with move_group client on ros1.

Have you got any ideas? Any suggestions will be appreciated. Thanks.

Same issue here. Did you find any solution?

I didn't find any quick solution, so I decided to port all my code in ROS2 and not use ros1_bridge

I assumed it was merged with the main repo. But apparently it is not.

I tried cloning the fork repo from here https://github.com/ipa-hsd/ros1_bridge.git. The package doesn't compile successfully. I am using ROS Noetic and ROS2 Humble. Following was the error message. Maybe I am not using the right ROS versions.

If I pull the changes made in the PR 256, I still am not able to compile. error.txt

The signature of goal_response_callback changed in humble. I'm working on a PR and still need to do a proper test. Something like the following worked in a brief test with noetic/humble on 22.04, with noetic in a conda env.

send_goal_ops.goal_response_callback =
        [this, &gh2_future](const ROS2GoalHandle & gh2) mutable {
          auto & goal_handle = gh2;
          if (!goal_handle) {
            gh1_.setRejected();          // goal was not accepted by remote server
            return;
          }

          gh1_.setAccepted();

          {
            std::lock_guard<std::mutex> lock(mutex_gh_);
            gh2_ = goal_handle;

            if (canceled_) {          // cancel was called in between
              auto fut = client_->async_cancel_goal(gh2_);
            }
          }
        };

I've gotten the action bridge working well enough with Noetic/Humble to execute motions on a motoman HC10. (I know there's a ros2 motoman driver, but it is currently set up for ros1). It's still a wip and I wouldn't trust it for anything serious.

Currently requires https://github.com/smith-doug/bridge_mapping as I didn't want to hardcode any mappings, but that might not be possible. Message types like Log change both the number of fields, and the values of the defined log severity levels.
