Build and publish a matching Jazzy Dev Container image. The selected image reports ROS_DISTRO=rolling despite its Jazzy tag. Its build imports moveit2_tutorials.repos, which tracks moveit_msgs on ros2, not .github/upstream_jazzy.repos at version 2.7.2. Build the image from the Jazzy base with the Jazzy overlay before using it here.

This new .repos file is added to workaround the build failure seen in https://github.com/moveit/moveit2_tutorials/actions/runs/33204073212/job/98960620701?pr=1075

Analysis by antigravity

Root Cause

    pilz_sequence.cpp:186:13: error: ‘struct moveit_msgs::msg::MotionPlanRequest’ has no member named ‘smoothness_level’     
      186 |   item3.req.smoothness_level = 0.3;      
  |     ^~~~~~~~~~~~~~~~     
  1. New Message Field for POLYLINE:
    PR Update pilz tutorials for POLYLINE planner #1075 Update pilz tutorials for POLYLINE planner #1075 adds tutorials for the new Pilz POLYLINE motion planner (introduced in moveit2#3610 Feature: New POLYLINE command in Pilz planner for space trajectory generation moveit2#3610). This feature adds smoothness_level to moveit_msgs/msg/MotionPlanRequest.msg.
  2. Jazzy Binaries Outdated: In jazzy-release, industrial_ci installs binary debian packages (ros-jazzy-moveit-msgs). Because smoothness_level has not been backported/released into the current ROS 2 Jazzy binary packages of moveit_msgs, the struct in
      /opt/ros/jazzy/include/moveit_msgs/... does not have that member.
    

I also confirmed moveit_msgs for Jazzy is 2.6.0 (ref. repo.ros2.org, ros/rosdistro#43732), which doesn't include the new capabilities that Polyline feature depends on.
Since I think the Polyline feature tutorial is already merged in, and this addion in PR seem useful addition to the tutorial, I want to add this PR even with workaround for jazzy readers.

# MoveIt msgs containing POLYLINE planner message definitions (e.g. smoothness_level).
# Required on pre-Kilted ROS distros (e.g. Jazzy) where debian packages lack these definitions.
# TODO: Remove once moveit_msgs with POLYLINE fields is released into targeted distros.

🌐 Web query:

ROS 2 launch XML <param from="..."> parameter file semantics and MoveIt robot_description_semantic SRDF

💡 Result:

In ROS 2, the <param> tag inside a <node> definition supports a from attribute as a direct replacement for the ROS 1 <rosparam> tag [1][2]. The from attribute specifies the path to a YAML file containing parameter definitions that will be loaded into the node [3][1][4]. The XML schema for this is: When dealing with MoveIt 2 and the robot_description_semantic (SRDF) parameter, it is important to note that the SRDF file is typically XML, not YAML [5]. The <param from="..."> syntax is designed for YAML files and is generally not suitable for loading the raw content of an SRDF file directly [5]. Because MoveIt 2 requires the SRDF to be provided as a string parameter (typically under the key robot_description_semantic), the standard approach is to load the file content into the launch configuration [5]. In Python launch files, this is commonly handled using the MoveItConfigsBuilder utility, which manages the loading of URDF, SRDF, and other necessary configurations automatically [6][7][8]. If you are not using the builder, you must read the SRDF file content into a variable in your launch file (e.g., using Python's open().read() or xacro.process_file()) and pass that content as a string parameter to the node [5][9]. For example, when using a Python launch file: move_group_node = Node( package='moveit_ros_move_group', executable='move_group', parameters=[{ 'robot_description_semantic': open(PATH_TO_SRDF, 'r').read, }],) If you strictly require loading parameters from YAML, ensure the target file is a valid YAML document where the SRDF content is stored as a string, though the procedural approach above remains the recommended and most common practice for MoveIt 2 [5].

Citations:


Load the SRDF into robot_description_semantic.

At lines 15 and 32, from loads a YAML parameter file. panda.srdf is XML, so these entries do not set robot_description_semantic and can cause parameter parsing to fail. Set robot_description_semantic to the SRDF contents in both nodes.

The POLYLINE motion command
---------------------------

.. note::

The ``POLYLINE`` planner and its parameters (e.g. ``smoothness_level`` in `moveit_msgs/msg/MotionPlanRequest <https://github.com/moveit/moveit_msgs/blob/ros2/msg/MotionPlanRequest.msg>`_) are natively available in binary releases for ROS 2 Kilted and newer. On earlier ROS 2 distributions (such as Jazzy), building ``moveit_msgs`` (version >= 2.7.2) from source is required.

This planner generates a continuous Cartesian trajectory passing through a sequence of waypoints.
The generated path is a combination of linear segments connected by
circular arcs to smooth the transitions between consecutive lines. A smoothness level scaling factor is used to
determine smoothness by scaling the max possible rounding radius.
The planner automatically filters waypoints that are positioned too closely;
however, the user must ensure the angle between consecutive segments is
sufficiently large to avoid violating minimum rounding constraints.
The planner uses Cartesian limits to generate a trapezoidal
velocity profile in Cartesian space. This planner only accepts a
start state with zero velocity. The planning result is a joint trajectory. The user needs to adapt
the Cartesian velocity/acceleration scaling factor if the motion plan fails due to violation of cartesian limits.
The planner will fail if three or more consecutive waypoints are collinear.
