Launch Error #2734

aagiser · 2024-03-10T14:04:55Z

Description

I have a problem with launcher. This problem is in source build installation, not binary. When I use binary, it works correctly. But when I install MoveIt 2 from source, it doesn't work. Note, tutorials launch files works without problems.

My environment

ROS Distro: Humble
OS Version: Ubuntu 22.04
Source build branch humble
Cyclone DDS

Steps to reproduce

I created a moveit package using setup_assistant. Its name is moveit2_package. After building and sourcing the workspace, I launched the launch file.
$ ros2 launch moveit2_package demo.launch.py

Expected behaviour

Opening RViz2 with the robot
It is correct when I install MoveIt 2 from binary!

Actual behaviour

An error occured.

Backtrace or Console output

[ERROR] [launch]: Caught exception in launch (see debug for traceback): 'capabilities'

Getting the same error on iron too, my environment:

ROS Distro: Iron
OS Version: Ubuntu 22.04
Source build branch iron

Project is a custom urdf. Haven't tried moveit2 with binary, will now!

Jakubivan · 2024-03-12T10:00:24Z

The output of ros2 launch moveit2_package demo.launch.py --debug is:
...

I got the same error on the same setup.

Probably because of
#2696 ?

mink007 · 2024-03-13T20:02:59Z

any luck with this issue?

I am having the same issue when launching "ros2 launch demo.launch.py rviz_tutorial:=true "

mink007 · 2024-03-14T05:41:25Z

when i install moveit2 from build from source, then i don't get this error "[ERROR] [launch]: Caught exception in launch (see debug for traceback): 'capabilities'".
But it is causing the robot model to not load in rviz.

i was looking for previous version number than "ros-iron-moveit/jammy,now 2.8.0-1jammy.20240213.190919 amd64 [installed]"
but was unable to figure out which the previous version number is. Was thinking of installing an older version to get around the issue.

apt list -a ros-iron-moveit
Listing... Done
ros-iron-moveit/jammy,now 2.8.0-1jammy.20240213.190919 amd64 [installed]

I recently experienced the same error when building a custom panda setup with the moveit_setup_assistant. I eventually traced my error to having built the colcon moveit_ws as instructed in their tutorial here: https://moveit.picknik.ai/humble/doc/tutorials/getting_started/getting_started.html. After removing the old log, install, and build folders from that old workspace in addition to my new workspace, I was able to launch my custom configuration based on the panda arm. My new workspace just included the panda_description package and my newly generated package that was generated by the setup_assistant and based on panda description package.

I also had a similar problem

I don't know if it's the right solution, but I solved it by editing the moveit_configs_utils code.

at ~/ros_ws/src/moveit2/moveit_configs_utils/moveit_configs_utils/launches.py line203

I also have the same problem and could not solve it with the solutions provided so far, any other ideas?

Too bad, this does not fix the same issue on my end.

Same here.

def generate_move_group_launch(moveit_config):
    ld = LaunchDescription()

    ld.add_action(DeclareBooleanLaunchArg("debug", default_value=False))
    ld.add_action(

    ld.add_action(DeclareBooleanLaunchArg("monitor_dynamics", default_value=False))

    should_publish = LaunchConfiguration("publish_monitored_planning_scene")

    move_group_configuration = {
        "publish_robot_description_semantic": True,
        "allow_trajectory_execution": LaunchConfiguration("allow_trajectory_execution"),
        # Note: Wrapping the following values is necessary so that the parameter value can be the empty string
        # Commented here
        # "capabilities": ParameterValue(
        #     LaunchConfiguration("capabilities"), value_type=str
        # ),
        "disable_capabilities": ParameterValue(
            LaunchConfiguration("disable_capabilities"), value_type=str
        ),
        # Publish the planning scene of the physical robot so that rviz plugin can know actual robot
        "publish_planning_scene": should_publish,
        "publish_geometry_updates": should_publish,
        "publish_state_updates": should_publish,
        "publish_transforms_updates": should_publish,
        "monitor_dynamics": False,
    }

    move_group_params = [
        moveit_config.to_dict(),
        move_group_configuration,
    ]

    add_debuggable_node(
        ld,
        package="moveit_ros_move_group",
        executable="move_group",
        commands_file=str(moveit_config.package_path / "launch" / "gdb_settings.gdb"),
        output="screen",
        parameters=move_group_params,
        extra_debug_args=["--debug"],
        # Set the display variable, in case OpenGL code is used internally
        additional_env={"DISPLAY": os.environ["DISPLAY"]},
    )
    return ld

I removed the launch argument as well as the capabilities parameter, and it works fine now. Do you know what the parameter is supposed to control?

I'm on ros2 humble and using I'm using a ur10e moveit config that I just created, with no additions to the urdf. I did not set virtual joints or an end effector.

I have fixed this issue by changing the line 199-206 into ld.add_action(DeclareLaunchArgument("capabilities", default_value="")) in the file ws_moveit/src/moveit2/moveit_configs_utils/moveit_configs_utils/launches.py

Same here.

def generate_move_group_launch(moveit_config):
    ld = LaunchDescription()

    ld.add_action(DeclareBooleanLaunchArg("debug", default_value=False))
    ld.add_action(
        DeclareBooleanLaunchArg("allow_trajectory_execution", default_value=True)
    )
    ld.add_action(
        DeclareBooleanLaunchArg("publish_monitored_planning_scene", default_value=True)
    )
    # load non-default MoveGroup capabilities (space separated)
    # commented here
    # ld.add_action(
    #     DeclareLaunchArgument(
    #         "capabilities",
    #         default_value=moveit_config.move_group_capabilities["capabilities"],
    #     )
    # )
    # inhibit these default MoveGroup capabilities (space separated)
    ld.add_action(DeclareLaunchArgument("disable_capabilities", default_value=""))

    # do not copy dynamics information from /joint_states to internal robot monitoring
    # default to false, because almost nothing in move_group relies on this information
    ld.add_action(DeclareBooleanLaunchArg("monitor_dynamics", default_value=False))

    should_publish = LaunchConfiguration("publish_monitored_planning_scene")

    move_group_configuration = {
        "publish_robot_description_semantic": True,
        "allow_trajectory_execution": LaunchConfiguration("allow_trajectory_execution"),
        # Note: Wrapping the following values is necessary so that the parameter value can be the empty string
        # Commented here
        # "capabilities": ParameterValue(
        #     LaunchConfiguration("capabilities"), value_type=str
        # ),
        "disable_capabilities": ParameterValue(
            LaunchConfiguration("disable_capabilities"), value_type=str
        ),
        # Publish the planning scene of the physical robot so that rviz plugin can know actual robot
        "publish_planning_scene": should_publish,
        "publish_geometry_updates": should_publish,
        "publish_state_updates": should_publish,
        "publish_transforms_updates": should_publish,
        "monitor_dynamics": False,
    }

    move_group_params = [
        moveit_config.to_dict(),
        move_group_configuration,
    ]

    add_debuggable_node(
        ld,
        package="moveit_ros_move_group",
        executable="move_group",
        commands_file=str(moveit_config.package_path / "launch" / "gdb_settings.gdb"),
        output="screen",
        parameters=move_group_params,
        extra_debug_args=["--debug"],
        # Set the display variable, in case OpenGL code is used internally
        additional_env={"DISPLAY": os.environ["DISPLAY"]},
    )
    return ld

I removed the launch argument as well as the capabilities parameter, and it works fine now. Do you know what the parameter is supposed to control?

no idea.... sorry. :)

+1 same issue here, just on Docker Rolling tutorial source image.

WilliamAStreamline · 2024-07-27T00:31:16Z

Same issue and the above changes to launches.py only seem to add more issues. Using Ubuntu 24.04 and Jazzy

b-adkins · 2024-08-08T00:13:39Z

I made a PR to revert the change: #2912

In the meantime, 7ce2fa9 is the last working commit on the Humble branch.

claralunasa · 2024-08-14T16:33:44Z

I have the exact same issues and the changes to the launch file haven't solved it for me

OneOneLiu · 2024-08-19T04:07:30Z

I also had a similar problem

I don't know if it's the right solution, but I solved it by editing the moveit_configs_utils code.

at ~/ros_ws/src/moveit2/moveit_configs_utils/moveit_configs_utils/launches.py line203

default_value=moveit_config.move_group_capabilities["capabilities"], -> default_value=moveit_config.move_group_capabilities,

Thanks, this solution works for me.

To provide more context, I am working on Ubuntu 22.04, ROS humble in a docker container. I installed moveit2 from binary and used setup assistant to create config files for a customized robot arm and gripper, the ros2 launch my_robot_moveit_config demo.launch worked well, but when I built moveit2 from source (to use Python binding), the same launch file produced the error

[ERROR] [launch]: Caught exception in launch (see debug for traceback): 'capabilities'

* this fixes an issue seen when no capabilities are defined (moveit#2734) * also adds ability to specify disabled capabilities

mikeferguson · 2024-10-02T18:16:57Z

I've opened #3018 to fix this - looks like we need to backport to both humble and iron as well

mikeferguson · 2024-10-16T15:30:28Z

Fix is merged into 'humble' (which this referenced) and 'main' branch. Still working on the 'iron' branch fix
