We do not yet have built in UI to trigger ROS services or actions. So to do this you would need to create a custom panel where you can make a button trigger callService

Ok , so i have managed to build the call service panel and it loads ok, so if the command i need to pass is

ros2 action send_goal /dock irobot_create_msgs/action/Dock

what do i put in service name and request ? tried a few different string but i just get errors

There is currently no builtin support for calling ROS2 actions. You will have to use the hidden services for that.

Below is an example for sending a goal to an action using the call-service example panel:

Note that when using foxglove_bridge, you will have to set the include_hidden parameter for that to work.

Just an update that we now have a built in service call panel: https://docs.foxglove.dev/docs/visualization/panels/service-call
