Thanks! I was able to execute the tutorial program. Just minor suggestions, basically approving.
Took a screenshot and posted on youtube https://www.youtube.com/watch?v=tfKC5PbwQZM Personally "how it looks when it works" for this Pilz and Moveit's RViz plugin is helpful so I suggest to include a link in the tutorial. I'm not trying to make money out of it :) but I understand if people yellow/red-flag agaist posting video link.

Btw, data structure the message Pilz uses may not be complexed but there are many ingredients in the hierarchy. Some visual like this eases my mind.

(This comment is for pilz_moveit.launch.py, which is not included in this PR. Referring to this line just to start a review thread)
Although it's likely out of the scope of this PR, pilz_moveit.launch.py file seems generic, there doesn't seem anything specific about either starting pilz specific processes, nor anything specific about tutorials (yes there are some specific things, which should be pass-able via arguments).
I'm guessing as a tutorial, it's valuable to have each tutorial as standalone project (then move_group.rviz is external to pilz tutorial part).
I don't know. Duplicating such generic files confuses me (especially in .launch.py format, which is hard for me to glimpse the content).

🌐 Web query:
For the MoveIt revision that contains PR #3610, does TrajectoryGenerator::setMaxCartesianSpeedrequire both a positivemax_cartesian_speedand a non-emptycartesian_speed_limited_linkto overridemax_trans_vel?
💡 Result:
Yes, in the MoveIt revision containing PR #3610 (and as seen in current implementations), the TrajectoryGenerator::setMaxCartesianSpeed function requires both a positive max_cartesian_speed and a non-empty cartesian_speed_limited_link to successfully override the default max_trans_vel [1]. The logic implemented in the function is as follows: if (req.max_cartesian_speed > 0.0 &&!req.cartesian_speed_limited_link.empty) { max_cartesian_speed_ = req.max_cartesian_speed; //... } else { max_cartesian_speed_ = planner_limits_.getCartesianLimits.max_trans_vel; //... } If either condition is not met (i.e., max_cartesian_speed is 0 or less, or cartesian_speed_limited_link is an empty string), the else block executes, falling back to the default max_trans_vel defined in the planning limits [1].

Set cartesian_speed_limited_link with every Cartesian speed override.
TrajectoryGenerator::setMaxCartesianSpeed applies max_cartesian_speed only when it is positive and cartesian_speed_limited_link is non-empty. The three sequence requests therefore fall back to max_trans_vel. Set the field to "panda_hand" in each item and add it to the LIN, CIRC, POLYLINE, and sequence examples.

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.

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].

- 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. - 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.

Add the required goal constraint for item3.
TrajectoryGenerator::validateRequest() calls checkGoalConstraints(), which rejects any request whose goal_constraints count is not exactly one. item3.req has no goal constraint, so the sequence request can be rejected before planning. Add the final waypoint after the loop:
Proposed fix

MoveIt 2 moveit_package CMake macro default C++ standard moveit_common
💡 Result:
In MoveIt 2, the moveit_package macro, defined within the moveit_common package, sets the default C++ standard to C++17 [1]. Within the moveit_package.cmake file, the macro explicitly configures the following CMake variables if they have not already been set [1]: if(NOT "${CMAKE_CXX_STANDARD}") set(CMAKE_CXX_STANDARD 17) endif set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS OFF) This macro is designed to consolidate common CMake settings across MoveIt packages to reduce boilerplate code [2][3]. By calling find_package(moveit_common REQUIRED) and then invoking moveit_package in a package's CMakeLists.txt, developers ensure consistent build configurations, including the enforced C++17 standard [1][4][5].

Use a C++17-compatible smoothness check.
moveit_package() defaults this package to C++17, and pilz_sequence has no target-specific standard override. The requires expression is C++20-only, so this target can fail to compile. Replace it with a C++17-compatible version guard or explicitly enable C++20 if supported by the package policy.
