ROS Discourse General: Open Hardware Summit 2025 CFP

header

Hi Everyone,

I want to take off my ROS hat :billed_cap: for a second and put on my Open Source Hardware Association (OSHWA) hat :cowboy_hat_face: for second.

As some of you may know I’ve been on the board of the Open Source Hardware Association for some time now. The OSHWA team is really busy with an exciting new NSF project at the moment so I am stepping up to help with organizing this year’s Open Hardware Summit. I presented a Lightning Talk at ROSCon about this year’s summit and the response was so positive I figured I should also make an announcement on ROS Discourse. I might also be in the process of planning a ROS meetup in Edinburgh. If that’s something you would be interested in helping with please reach out to me directly via DM.

Open Hardware Summit 2025

This year’s Open Hardware Summit will be held in Edinburgh, Scotland on 2025-05-29T23:00:00Z UTC→2025-05-30T23:00:00Z UTC and tickets just went on sale. If you’ve never been to Open Hardware Summit you can get a taste of the event by watching our 2024 Summit Live Stream. Our keynote this year was from Danielle Boyer, a Ojibwe roboticist who is builds open hardware educational robots that teach students their indigenous languages.

OSHWA currently has an open call for proposals for this year’s Open Hardware Summit. If you have an open source hardware robot, or an interesting open hardware project that you would like to share, please consider submitting a talk or workshop proposal! Applications are due by 2024-12-22T08:00:00Z UTC.

While I have your attention…

I want to remind the ROS community that they should consider certifying their open hardware designs! Certification ensures that your project meets the minimum documentation requirements to be considered open source hardware, lists your project on our certification website, and provides you with a slick badge that you can include on your designs.

The OSHWA certification website is a gold mine of close to 3000 open hardware projects that you are free to study and use as part of your robotics project. The certification website currently includes 19 different motor drivers (like this stepper driver and this Grove Motor Driver from TU Delft ), 229 different robots (such as the NASA JPL Rover), and 312 different sensors (like this line sensor, and this pneumatics controller). I recommend you bookmark the certification website for easy reference!

ROS Discourse General: Introducing FIREBRINGER - A generalised autonomous navigation algorithm

Hey all,

Our company GEEAR (full announcement soon) has been developing FIREBRINGER - a generalised autonomous navigation algorithm implemented on ROS2 for field-robotic applications.

The algorithm is meant to support a variety of missions from simple point-to-point travelling and trajectory tracking, to more advanced interaction with third-party vehicles and our favourite - real-world dense robotic swarms (in the full academic sense of emergent collaborative behaviour). We will continue working on populating our library of mission types/functionalities so you can expect more in the future.

So far we have validated FIREBRINGER on real-world boats and ground vehicles and on copters and fixed-winged aircraft in gazebo, (real-world experiments coming soon). You can find our recent video unveiling our autonomous vessel prototype here.

The algorithm is meant to be easy to use and tune, only requiring basic physical characteristics of the robot (maximum linear/angular velocity and maximum acceleration for each degree of freedom of the robot), and it offers plug-n-play functionality when combined with an Ardupilot autopilot through MAVROS.

It is based on a lightweight, robust NMPC-variant integrated with artificial potential field theory. It can typically run at 100Hz on a normal PC and 25Hz on a RPi4B for all vehicle types. So far, it can receive topics regarding the location of other vehicles (third-party and collaborative), trajectory (e.g., NAV2 global path), destination (complete pose), and various other mission specific info. We are currently working on incorporating point-cloud/costmap information for surrounding obstacle avoidance. Our aim is to allow integration with any ROS2 perception package that may be used in field robotics. The algorithm outputs an optimal velocity for each degree of freedom so it needs to be combined with appropriate low-level actuation control (or connected to a well-tuned Ardupilot autopilot which will do the work).

We are currently considering creating and publishing a complete ROS2 package for the algorithm and we may propose some type of fusion with NAV2 in the future, but we wanted to gauge interest first. Obviously we are open to ideas and recommendations (and some criticism)!

ROS Discourse General: Clarification of Infrastructure PMC meeting time

tl;dr:

Infrastructure PMC meetings are held online at Mondays 16:00 UTC

The event is open to public observers who can join via the information on the OSRF Official Events calendar

Hello everyone,

The Infrastructure Project Management Committee meeting has been on the OSRF Official Events calendar since we made the switch from the earlier Infrastructure Project Committee to the OSRA-chartered Infrastructure PMC.

When I created the event, I accidentally did so using my local timezone instead of UTC pinning, as result, the meeting time was shown an hour later than previous weeks when the US clocks changed. Another PMC member noticed and reported this and I corrected the event.

My apologies to observers who joined an hour later, when the meeting time was originally posted.

ROS Discourse General: Interoperability Interest Group November 07, 2024: What's in an interface?

Community Page

Meeting Link

Calendar Link

2024-11-07T15:00:00Z UTC

That which we call an API by any other name would serve just as well. But when there are many diverging opinions on exactly what names to use or exactly how to structure things, we may end up scattering our efforts instead of working together.

The OSRA TGC opened a technical committee to examine the ROS Enhancement Proposal (REP) process to refine it and apply it to all of the projects that are governed by the OSRA, including Open-RMF. The PMC of Open-RMF sees this as an opportunity to formalize something similar to a Request For Comments (RFC) process for Open-RMF where we can define interfaces for our next generation development and receive comments from the public, especially from stakeholders, to make sure that we’ll be developing the most useful tools possible for everyone. This would also define a formal way for anyone from the general public to propose new interfaces for Open-RMF to support.

At this session of the special interest group, Grey will present a working draft of what kind of process we are considering for Open-RMF.

We are eager to get feedback from the Open-RMF community and beyond about how to make this process as effective as possible. Effectiveness would be measured both in terms of making sure we are producing the highest quality stable interfaces possible and also getting contributions (proposals, feedback, and implementation) from as many community stakeholders as possible.

After presenting our current ideas, we want to open up the session to discussion and feedback, so please come ready to share your own thoughts. We will especially appreciate input from anyone that has experience (both positive and negative experiences) working with standardization bodies.

ROS Discourse General: Kobuki in ROS 2 Jazzy & Rolling + Gazebo Harmonic

Hello everyone!

Let me introduce myself, my name is Juan Carlos Manzanares and I belong to a robotics research group called Intelligent Robotics Lab , belonging to the Rey Juan Carlos University, Madrid, Spain. In this group we develop some projects, such as MOCAP4ROS2 , PlanSys2 , CascadeLifecycle, marathon for nav2 , robocups, go2_robot, tiago_harmonic…

Today I would like to show you a package that we have prepared to be able to install and use TurtleBot2 Kobuki in a more comfortable way, either with a real robot or using the new gazebo simulator.

This package directly uses the kobuki_ros packages, which have been tested and prepared so that they can be used in the Jazzy and Rolling versions. In addition, I have retouched the urdf to my liking, so that in a more comfortable way you can add/remove the camera and lidar sensors, the structure, or indicate whether or not you are going to use the gazebo plugin.

Real Kobuki in ROS 2 Jazzy

Simulated Kobuki in Gazebo Harmonic ROS 2 Jazzy

Finally, it is also prepared so that you can launch Navigation2 from the package.

Real Kobuki using Nav2 in ROS 2 Jazzy

Simulated Kobuki using Nav2 in Gazebo Harmonic ROS 2 Jazzy

This package is being used by students from the Rey Juan Carlos University, and I hope it will be useful to all of you who have a kobuki and don’t know what to do with it. And of course, we are open to any PR to make everything work better, any problem you find, or to clarify the steps much more.

Thank you very much for reading the post and I hope it helps many of you.

Greetings.

ROS Discourse General: Iron Irwini EOL Plan

Hello everyone,

ROS 2 Iron Irwini which was released on 23rd May 2023 is a non-LTS release and is due to be marked end-of-life (EOL) by the end of November 2024.

If you are using Iron, it is strongly recommended to switch to Jazzy Jalisco which will be supported until May 2029.

Once EOL, we will no longer release updates to core and community managed packages through the ROS Buildfarm. We will also not backport any changes to the iron branches of core repositories. The distribution will be frozen forever.

The plan for the next month is as follows:

If you’re a maintainer of a package released on Iron, this is your call to get the final versions of your packages released on the Buildfarm over the next couple of weeks. Remember Iron will be in sync hold a few days prior to Nov 15th so please plan in advance.

ROS Discourse General: FOSDEM 2025: Robotics & Simulation... first edition!

We’re excited to announce the first Robotics and Simulation devroom at FOSDEM 2025, scheduled for Sunday, February 2nd in Brussels!

A Robotics and Simulation developer room at FOSDEM, focused on core robotics libraries, frameworks, simulation tools, and open-source platforms. The selected talks will cover key tools like ROS and Gazebo, showcasing advancements and projects in the field. The half-day event will feature four presentations and a lightning talk session, offering a platform for developers to share work and foster collaboration.

Scope of Talks

Because of the varied and interdisciplinary nature of robotics as a field, plenty of topics could fit a ‘Robotics and Simulation’ devroom. To help the speakers target their presentations to a specific audience, and to minimize the overlap with other established FOSDEM devrooms, we defined the scope of this devroom by listing key areas of interest:

The examples mentioned are meant to be descriptive and not restricted. Talks could be improvements to any of the mentioned packages, interesting uses of them, alternatives with different degrees of maturity, or totally unrelated to them.

Submission instructions

Talks proposal submission:

See you in Brussels!

ROS Discourse General: ROS2 diagnostics from Jetson with jrosclient and isaac_ros_jetson_stats

Hi,

ROS2 diagnostics messages are part of jros2client starting from version 10.0.

We wrote a short article which covers how users can use ROS2 diagnostics, by subscribing to it with jros2client directly from Java. All received ROS diagnostics message are converted to OpenTelemetry metrics and sent to OpenTelemetry for further processing.

In our example, as a source of all diagnostics we use Jetson Orin Nano. All diagnostics from Jetson is gathered and published to ROS by isaac_ros_jetson_stats.

The entire flow looks like this:

ROS Discourse General: Vizanti Mission Planner - Jazzy Release, RWS, & Other News

Hey everyone :wave:

You know, I’ve suddenly realized been over a year since my last post on this topic and there have been a lot of additions so I figured I ought to compile a short rundown of the more notable bits.

For those new to it, Vizanti is a community maintained open source control and visualization command center for ROS 1/2 in the web browser, targeting primarily outdoor use cases like marine, field, and aerial robotics on mobile and desktop devices.

image

Jazzy Release

This mainly involved waiting for rosbridge and rws to update, since there was little in terms of breaking changes. So far the ros2 branch can stay common to both Humble and Jazzy, which reduces overhead for backporting changes. The stability and usability is now more or less on par with Noetic, which will continue to get equal feature updates at least until the end of 2025 as well.

Well I wrote “release” there, but there isn’t exactly an apt release for the package yet, for various popen, rws, and other reasons. TBD.

RWS - ROS Websocket Server

Since web browsers are mostly restricted to TCP and as such can’t really connect with a DDS (or even ros_comm for that matter), an intermediary server is needed to pack traffic up into websockets.

Originally this was established by rosbridge suite on ROS, but due to a multitude of reasons it’s not nearly as performant on ROS 2. That’s why I’ve been working with v-kiniv to integrate his drop in replacement server, RWS.

There were a few things to fix up and a feature or two to add, but after nearly a year I think we’re at a point where it’s basically there now.

While a bit more of a hassle to set up, it uses significantly fewer resources while providing much higher throughput, enabling use on low end platforms like the Pi 4 and 5 where the ROS 2 version of Rosbridge isn’t efficient enough to function under typical load.

Right now it’s the recommended backend to use with Vizanti on Humble and Jazzy. And unless you’re using client side services, probably for your roslibjs project as well.

Updates

There are a handful of new widgets, and a few existing ones have been expanded to support multiple topics for better compatibility.

Grid Cells

This one is somewhat underused in Rviz in my experience, but extremely efficient for sparse grid data, such as the occasional obstacle in an open field. Comes in any 24-bit colour.

image

Altimeter

Yes a way to finally see the Z axis, very good. Ah, but it’s not just for observation, tapping the meter sends a Float32 target with the clicked value for direct depth/altitude control.

image

What it tracks exactly is the position of a chosen TF link relative to the fixed frame. Comes in depth (blue) and altitude (green) versions with adjustable units, but doesn’t do both at the same time. I have to apologise if any of you happen to be working on aerial submarines, but those simply won’t fly. :wink:

ezgif-6-4e41f79b5d

Folder

Is your tiny screen getting filled up with rows and rows of widgets? Well, now they can be grouped together, just like in rviz.
image

image

There are some limitations, mainly that the widget has to be created in the folder and can’t be moved around. I’m still figuring out a way to even conceptually do that UX-wise now that both the short and long click are taken, and mobile has no right click…

Speedometer

Okay this one’s a bit funky, it lets you measure the relative speed of any two tf links in various scientific (and unscientific) units. A handy thing to check if your nav stack is set to drive at the correct velocity and/or if your boat props have weeds in them.

speedo
In the gif above, the first few dials track turtle1 relative to world in various units, the next one turtle1 relative to turtle2, final one tracks turtle2 to world.

General improvements

Covariance rendering is correct now:

image

(what do you mean it was wrong before :grimacing:, aaah you saw nothing)

The icons will reflect the visualizer color by recoloring the svg, so it’s easier to find which icon corresponds to what’s being rendered:
image

Map rendering has code-exact rendering parity with rviz in terms of colour mapping (as well as the raw display mode), except for a slightly more transparent tinge for unknown pixels, which imo looks slightly better:

image

TF frames now get grouped together by prefix, for clarity:

image

Community Contributions

A notable change to the satelite tile renderer was started by kosmonauta144 and darkhannibal, which enabled the use of other tile zoom levels, letting you see your robot from orbit:

ezgif-7-2934900ceb

The tiles themselves are now exportable and importable, so it’s possible to just load up the entire area beforehand and load it up offline on another device.

Thanks to samkys, all versions now also support building and running a Docker container, for those of you trying to run the wrong versions of ROS on the wrong OS :man_facepalming:

image

I also have to thank tony2guo for adding base url support, which essentially lets you namespace the browser path, and of course v-kiniv for his continuing help in integrating RWS.

Etc.

And there’s of course a lot of gradual improvements in general stability, rendering accuracy, speed, etc. There is also a github wiki now that contains everything from introductory to more esoteric info.

In Conclusion?

Well there’s still a lot left to do, features and visualizers to add, widgets to rework, performance to improve, bugs to fix, Firefox rendering to speed up. If anyone feels like helping along or has a good idea, I’m always up for a code review :wink:

ROS Discourse General: ROS 2 Migration Sprint

Hello everyone,

With 7 months left before the Noetic EoL and as a way to conclude this year’s edition of ROSCon, I was wondering if there are any open source projects that require help to migrate to ROS 2?

Otherwise, I also know that there are projects that are searching for contributors, especially for documentation. If you’re maintaining or contributing to a ROS-related open-source project with good first issues for new contributors, please share the link to your project here :slight_smile:.

For example, here is a link on the ROS 2 Documentation Website with tips for contributing to the ROS 2 project.

Thanks !

Isaac Saito: To rename ROS package systematically

Not specific to ROS, but still nice to have a memo like this for myself.

A couple of scripts can be used when you change the name of your ROS package "foo" to "bar".

1:  cd /tmp && cp -R `rospack find foo` .  
2:  (shopt -s nullglob && _() { for P in "$1"*/; do Q="${P//[Ff][Oo][Oo]/bar}"; mv -- "$P" "$Q"; _ "$Q"; done } && _ ./)  
3:  find . -type f -print0 | xargs -0 sed -i 's/foo/bar/g'

Line by line:

If you want to change the packages you've already "released", see this thread.

----

Update 2024/10/21 If the targeted files are under (a local) git repository, there's much more user-friendly command (thanks to superuser.com#1110337).

git grep -lz foo | xargs -0 sed -i '' -e 's/foo/bar/g'
