ROS Discourse General: World Magnetic Model 2025 released (and WMM2020 ending very soon!)

If you’re using magnetometers and World Magnetic Model on your robots, pay attention!

The World Magnetic Model 2025 (with validity 2025-2030) has been released by NOAA a few days ago (they made it before DOGE starts biting :smiley: ).

What’s more important, WMM2020 validity ends on 31 Dec 2024. If you’re using the model and check for validity, it is time to update pretty fast! If you don’t check date validity, your model will probably still work fine, but the error would be larger and larger.

If you’re using GeographicLib, it hasn’t adopted the new model yet, but the data are already provided by a side-channel: How to apply WMM2025 model in GeographicLib? · Issue #34 · geographiclib/geographiclib · GitHub .

If you’re using magnetic_model ROS package, WMM2025 will be included in its next release.

ROS Discourse General: Time to give your magnetometers a big refresh!

Are you using magnetometers on your robot? And are you using them right? Did you know each magnetometer has a bias that needs to be removed?

I’d like to announce the release of our suite of magnetometer tools that could be helpful to lots of people who deal with outdoor navigation.

The release is for ROS Noetic currently. We’ll definitely port the stack to ROS 2 some time next year.

I’ll be happy for feedback!

magnetometer_pipeline

To calibrate your magnetometer (i.e. identify its bias), use node magnetometer_pipeline/ magnetometer_bias_observer . Just spin up the node, call service /calibrate_magnetometer and you have 30 seconds to rotate your robot about as many axes as you can. This corresponds to the 8-shape phones sometimes want you to do.

Using a magnetometer without calibration is bad, bad, bad! The outputs are usually pretty much nonsense. Do not do it.

Once the magnetometer is calibrated, bias is published on topic /imu/mag_bias. Node (and nodelet) magnetometer_pipeline/magnetometer_bias_remover can take the raw /imu/mag data and remove the bias from them, providing topic /imu/mag_unbiased.

magnetometer_compass

To convert the magnetometer measurement to a heading, use node(let) magnetometer_compass/magnetometer_compass. It eats /imu/mag_unbiased and /imu/data (with orientation) and extracts azimuth (heading).

As there are multiple possible ways to express azimuths, magnetometer_compass supports all imaginable combinations:

Azimuth reference:

Azimuth orientation:

Units:

Output data types:

To be able to convert between magnetic and true North, magnetic declination needs to be known. This value depends on GNSS position, so the compass node can eat NavSatFix messages which tell it where the robot is. Or, if the position is predictable/static, you can set it as a config parameter and then you don’t need to provide the NavSatFix messages. The resolution of the magnetic model is ~3500 km, so you don’t need to be very precise here.

Magnetometer measurements can be quite noisy. Therefore, magnetometer_compass contains a built-in low-pass filter with configurable strength to make the azimuth reading a bit more stable.

Once you get the magnetometer_compass running, you might want to visualize its output using magnetometer_compass/visualize_azimuth, which can eat any of the above-defined outputs.

Some magnetometer drivers (ethzasl_xsens_driver, I’m looking at you) mix up the units in the magnetometer part and report in Gauss instead of Tesla (1 T = 10000 G). Fortunately, for just identifying the azimuth, this is no problem!

compass_conversions

As can be seen above, there are quite a lot of ways to express an azimuth. compass_conversions provide a C++ library, message filter and nodelet that can convert any kind of azimuth to any other kind.

Using the message filter, it is quite simple to subscribe to any kind of azimuth representation and get the one you actually need in your code:

message_filters::Subscriber azimuthInput(...);
message_filters::Subscriber fixInput(...);
compass_conversions::CompassFilter filter(log, nullptr, azimuthInput, fixInput,
  compass_msgs::Azimuth::UNIT_RAD, compass_msgs::Azimuth::ORIENTATION_ENU,
  compass_msgs::Azimuth::REFERENCE_GEOGRAPHIC);
filter.registerCallback([](const compass_msgs::AzimuthConstPtr& msg) {
  ...  // Handle the data which come geographic-referenced, ENU oriented, in radians
});

Analogically, you can spin up compass_conversions/compass_transformer to do this conversion at the ROS API level.

magnetic_model

Converting magnetic North to true North requires knowing the magnetic declination. This is a value provided by World Magnetic Model. magnetic_model is a C++ library that provides easy usage of the model with ROS data types. In addition to what GeographicLib already provides, magnetic_model also knows the error model of the conversion, so it can also tell you the variance of the conversion.

This package comes with all available releases of WMM preinstalled, so there’s no need to get the data elsewhere. But it still supports customizing the path to the folder with models - just in case you need to use something different.

ROS Discourse General: How do you monitor your robot diagnostics (topic rates)?

Hi all!

What kind of tools do you use to monitor your robots in runtime? I’m especially interested in monitoring ROS 2 topic rates to confirm for example that all the sensors are publishing data correctly.

I’m looking for a solution that could do this without large overhead, and that would preferably work “from outside”, without injecting code to the subscriptions/publishers. It should publish ROS Diagnostics messages if the expected rates are below the given thresholds.

Is there a solution that can already do this? I’ve so far checked for example ROS 2 built-in Topic Statistics and ros2_tracing, but they don’t seem to fulfill these requirements.

I would be also interested in hearing how you monitor the other aspects of your robots, such as network usage, Node health, etc.

Hello everyone,

I was wondering what kind of visualizations tools do you use or are aware to see the architecture of a ROS 2 system?

For instance, if you would like to see the connections between nodes and topics (e.g., I know that rqt can show that), visualize messages flow, parameters, or even documentation.

Thank you!

ROS Discourse General: Global Robot Density in Factories Doubled in Seven Years - What's the impact of ROS?

Has anybody read this news? What’s your opinion on the impact of ROS here?

Global Robot Density in Factories Doubled in Seven Years

New World Robotics Data by International Federation of Robotics reveal

Frankfurt, Nov 20, 2024 — Robot adoption in factories around the world continues at high speed: The new global average robot density reaches a record 162 units per 10,000 employees in 2023 - more than double the number measured only seven years ago (74 units). This is according to the World Robotics 2024 report, presented by the International Federation of Robotics (IFR).

Robot density serves as a barometer to track the degree of automation adoption in the manufacturing industry around the world," says Takayuki Ito, President of the International Federation of Robotics. “This year’s runner-up is China, which ranks third worldwide behind Korea and Singapore, but right up with Germany and Japan."

Robot density by region

The European Union has a robot density of 219 units per 10,000 employees, an increase of 5.2%, with Germany, Sweden, Denmark and Slovenia in the global top ten.

North America´s robot density is 197 units per 10,000 employees – up 4,2%. The United States ranks tenth in the world among the most automated countries in the manufacturing industry.

Asia has a robot density of 182 units per 10,000 persons employed in manufacturing - an increase of 7.6%. The economies of Korea, Singapore, mainland China and Japan are among the top ten most automated countries.

Top countries

The Republic of Korea is the world´s number one adopter of industrial robots with 1,012 robots per 10,000 employees. Robot density has increased by 5% on average each year since 2018. With a world-renowned electronics industry and a strong automotive industry, the Korean economy relies on the two largest customers for industrial robots.

Singapore follows with 770 robots per 10,000 employees. Singapore is a small country with a very low number of employees in the manufacturing industry, so it can reach a high Robot density also with a relatively small operational stock.

China took third place in 2023, surpassing Germany and Japan. The country’s push to the use of automation technology results in a high robot density of 470 robots per 10,000 employees (2022: 402 units). China only entered the top 10 in 2019. It has managed to double its robot density within four years.

Germany ranks fourth with 429 robots per 10,000 employees. The robot density of Europe´s largest economy has grown by 5% CAGR since 2018.

Japan is in fifth place with 419 units. Robot density of the world´s predominant robot manufacturing country grew by 7% on average each year (2018-2023).

Robot density in the United States reached 295 units in 2023. The country ranks tenth in the world.

About Robot density

Robot density is the number of operational industrial robots relative to the number of employees. It can cover the whole manufacturing industry or just specific industrial branches. The number of employees serves as a measure of economic size, so the quotient of operational stock over employees puts the operational stock on a uniform base.

ROS Discourse General: Is there a ROS 2 gazebo project for humanoids robots?

Dear ROS community,

I was researching if there are ROS 2 Gazebo project for humanoid robots that would facilitate in learning robot locomotion and whole-body motion planning. I am looking towards humanoids similar to Unitree’s H1/H2.

A research scientist from ETH Zurich pointed me to the Issac Gym environment that comes with the assets for H1/H2. But as far as I understand, that simulation pipeline does not use any ROS, and is meant for RL like research.

The closet project I found was Unitree’s ROS 1 project GitHub - unitreerobotics/unitree_ros but it has not been updated for the newer ROS 2 and Gazebo.

Thank you for your time.

With best,
Azmyin

ROS Discourse General: Opinion on companies still using ROS1

I would like to read what you think about taking a Job in companies who work extensively with ROS, but for one reason or another they are still in ROS1.
On one hand I realize that ROS is just a framework and that a lot can still be done and learned.
On the other, having worked for some years on both ROS and ROS2 I see the benefits of working with ROS2.
So I am torn and would like to hear other voices on the matter.

I want to send a big shout out @abaeyens for putting together this fantastic documentation on ROS 2 integration testing for docs.ros.org. :tada:

People often ask us how they can best contribute to the project. My recommendation is that when you run across something that feels not poorly documented take the time to summarize what you learned while figuring out how to solve the problem. That’s exactly what @abaeyens
did in this case and the results are excellent.

ROS Discourse General: REUSE compatibility vs multi-package repo

Hi. I’ve started trying to have my repos REUSE-compliant.

It seems that single-package repos can easily be turned into REUSE-compliant by adding all the SPDX comments to files, moving the top-level LICENSE file into LICENSES/BSD-3-Clause.txt and specifying <license file="LICENSES/BSD-3-Clause.txt">BSD</license> in package.xml.

However, if I want to do the same for a multi-package repo, then the LICENSES folder has to be a top-level one, i.e. at the same level as are the packages (that is a REUSE requirement). At the same time, I’d like to not have to copy all licenses to each package - as it’s best if each is stored only once. However, if I put <license file="../LICENSES/BSD-3-Clause.txt"> in package.xml, then bloom-release fails not being able to find the license file. That’s because it builds each package from the repo in a separate directory that is moved outside the repo.

I don’t see a clean solution how to satisfy both REUSE and bloom (except not adding the file= attribute, but I’d like to keep it). My current dirty workaround is to just copy the license file into the root of each subpackage. That’s not nice, but it does the job.

Does anybody know of a cleaner solution? I think it would be very nice if ROS deployment process would be compatible with REUSE.

ROS Discourse General: Optimizations cpp ROS2 node. colcon build

I’ve been using ROS2 for a year. Maybe previously you guys talked about this. However I’ve done experimental tests about the optimization C++ code ROS2 node and wrote a simple node.

#include "rclcpp/rclcpp.hpp"

class HelloWorldNode : public rclcpp::Node
{
public:
    HelloWorldNode() : Node("hello_world_node")
    {
        RCLCPP_INFO(this->get_logger(), "Hello, World! This is a ROS2 node.");
    }
};

int main(int argc, char **argv)
{
    rclcpp::init(argc, argv);
    rclcpp::spin(std::make_shared<HelloWorldNode>());
    rclcpp::shutdown();
    return 0;
}

Then by simply building the above code by using

colcon build

I got hello_node then explored assemble code

objdump -d <path>/hello_node > hello_node.asm

got around 5000 lines of instruction code in hello_node.asm, it seems like it didn’t do any optimization to the code. Then run the following command

colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release
///alternative
colcon build --cmake-args -DCMAKE_CXX_FLAGS="-O3 -march=native"

then looked number instructions lines the number dramatically decreased from 5000 to 1700. the number of instruction lines in assemble doesn’t always mean it’s optimized yet it’s good factor.

Screenshot from 2024-12-11 16-24-11

“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”“”"
simple by adding “set(CMAKE_BUILD_TYPE Release)” to your CMakeLists.txt is enough. then you can simply use colcon build.

ROS Discourse General: :checkered_flag: Gazebo Garden officially end-of-life [x-post Gazebo Sim Community]

Original Post

Dear ROS Community,

Gazebo Garden has reached end-of-life (EOL) as of November, 2024. Garden was the seventh major release of Gazebo and was supported for two years (non-LTS). It was the first release where Ignition was renamed Gazebo. It also introduced various exciting features, including custom shader plugins, Reset API, DEM support, lunar and custom surface coordinates, glTF and GLB mesh support, and an acoustic communication plugin, just to name a few. See the entire list of features on the Release Features page.

We recommend all Garden users migrate to a supported release as soon as possible, such as Harmonic (LTS) or Ionic, which are paired with ROS Jazzy and Rolling (Kilted once released) respectively. Migrating to either Harmonic or Ionic should be fairly smooth, however, be sure to check the release highlights for Harmonic and Ionic in addition to checking each Gazebo library’s migration guide.

As part of the Garden EOL, the following Gazebo libraries have also reached end-of-life. Their latest released binaries will remain available at http://packages.osrfoundation.org/, but no more fixes or releases will be made.

Library major version Final release
gz-fuel-tools8 8.2.0
gz-sim7 7.9.0
gz-gui7 7.2.2
gz-launch6 6.2.0
gz-msgs9 9.5.1
gz-physics6 6.7.0
gz-rendering7 7.5.0
gz-sensors7 7.3.1
gz-transport12 12.2.2
sdformat13 13.9.0

We sincerely thank all contributors to all libraries in Garden :pray:

What does End of Life Mean?

Users often ask us, “what does end of life mean?” To put it briefly, end of life means that the Gazebo team will no longer support that particular Gazebo release. In practical terms, this means that we will no longer be providing the following for Gazebo Garden:

It is also worth noting the things that won’t change after Gazebo Garden goes end of life:

ROS Discourse General: Iron Irwini is End-of-Life

Dear ROS Community,

It is bitter-sweet to announce that ROS 2 Iron Irwini is now end-of-life.

ROS 2 Iron Irwini

Iron Irwini was released on May 23rd 2023 and marked the ninth distribution of ROS 2. Despite being a non-LTS release, it was feature packed (see more).

Over the past year and half, there have been 40 distro syncs and 7 patch releases that cumulatively brought thousands of packages and updates to the community.

The last patch and sync (tagged iron/2024-12-04) brought 6 new packages and 320 updates.

Expand for details of the final sync (click for more details)

The distribution has been marked end-of-life across docs.ros.org, index.ros.org and rosdistro. CI and Buildfarm jobs have been disabled and will be deleted after a month assuming no issues crop up. The final snapshot of the distribution has been uploaded to snapshots.ros.org. If you are currently using Iron, please switch to Jazzy Jalisco which is the latest LTS release. The transition should be very smooth.

It has been a great privilege of mine to serve as the ROS Boss for Iron Irwini especially given that Steve Irwin was my childhood hero. A big thank you to all ROS maintainers and community members for making Iron Irwini such a successful release! :iron: :irwini:

ROS Discourse General: rmw_iceoryx2 v0.1.0 release

Hi all,

orecham here, one of the committers from the eclipse-iceoryx project.

I’m pleased to announce the alpha release of rmw_iceoryx2, compatible with ROS 2 rolling and available at: GitHub - ekxide/rmw_iceoryx2: ROS 2 RMW implementation for iceoryx2

Why yet another RMW? We have the following goals for rmw_iceoryx2:

  1. Bring the high-performance zero-copy shared-memory communication offered by iceoryx2 to ROS 2 applications
  2. Provide a unique option for reducing safety certification effort of ROS 2 applications with safety-critical use-cases

Rather than require the entire ROS 2 stack be certified (e.g. for ASIL-D), rmw_iceoryx2 offers an alternative through interoperability between ROS 2 and iceoryx2 applications. This allows the freedom for porting safety-critical components that require certification to iceoryx2 (which is designed for certification) while still participating in the ROS 2 ecosystem.

Current State

With this first alpha release, there is still some work to do and polish to be made. Not all features are yet available and existing ones need thorough real-world validation. Most notably, support for message serialization is not yet available nor service-client communication (waiting on some features to be completed in iceoryx2). Lack of serialization support means that rmw_iceoryx2 can currently only work with self-contained message types, however, this will be one of the first limitations to address next.

Furthermore, only intra-host communication is currently possible. We have plans to introduce host-to-host capabilities in the near future by leveraging existing host-to-host-capable middlewares. Some more info about this is available in the README.

Performance

The current performance_test results are as follow. There is still quite a bit of room for improvement compared to raw iceoryx2:

v0.1.0

Contributing and Feedback

We look forward to your feedback! Input from real-world application configurations will be invaluable for bringing rmw_iceoryx2 to stability. Additionally, insights from those experienced with RMW implementations would greatly help improve quality. The current state was achieved using only the information available in the RMW documentation, thus there may be some edge-cases known to veterans which are not properly addressed.

For those who have the capacity to get involved with implementation, we welcome all contributions! We will provide as much support as needed to those who are interested.

Thanks for reading!
Cheers

ROS Discourse General: Open-RMF PMC Timing Change for 2024-12-17

Due to a one-time scheduling conflict, the Open-RMF Project Management Committee session that is normally scheduled for 2024-12-17T01:00:00Z UTC will instead take place one hour later at 2024-12-17T02:00:00Z UTC. This change is reflected in the official OSRF events calendar.

Sessions will return to the normal time afterwards.
