Hello everyone, We would like to introduce lint_launch , a tool meant to check your launch files for common errors without attempting to launch any processes. We originally developed this tool for ROS2 Humble and have been using it internally for a few years. We recently decided to open-source it in the hope that it can be useful to the community. Features: Checks your launch files without actually starting them. This can be used CI to ensure that robot-specific launch files remain in a working

Background I am evaluating Open-RMF for a dense industrial production environment similar to a semiconductor fabrication facility. The environment contains: Many AMRs operating simultaneously Long and narrow bidirectional corridors Bottleneck sections that can accommodate only one or two robots Limited passing and pull-aside space Robots dynamically entering the traffic system Frequent route overlap, negotiation, stop-and-go behavior, and deadlock risk In this type of environment, minimizing the

ROS News for the week of August 10th, 2026 Just ten days remain to purchase regular price tickets for ROSCon Global in Toronto. If you need corporate approval to travel to ROSCon it is now or never! Next week is Foxglove’s Actuate conference in San Francisco. There are also various meetups and events affiliated with Actuate that are happening that week as well. The following week we have a Trossen X ROS Industry Night in San Francisco, our online Gazebo Community Meeting on reinforcement learnin

Hi all, I am part of Black Bee Drones, an autonomous drone team at the Federal University of Itajubá (UNIFEI) in Brazil. We developed Nectar SDK, a ROS 2 toolkit for the companion computer, so control, cameras, and perception sit behind one set of interfaces instead of being rebuilt for every mission. It started around 2023 as shared mission code. We use it for indoor and outdoor competitions (IMAV, CBR, SAE), lab tests, and research, including IMAV indoor (3rd in 2023 and 2025) and SAE Eletroqu

Hi everyone, I’ve been building Metriplane , an open-source tool for turning recorded robotics and manufacturing state into an inspectable incident and a repeatable regression test. I just finished a new short demo that shows the use case much more clearly: A pallet is ready at an outfeed station. An AGV is expected to arrive within 60 seconds. It does not. The PLC knows the pallet is ready. The robot or ROS 2 side knows where the AGV is. Metriplane evaluates that process condition across the re

LaserPerception v0.1.0 — PointPillars + TensorRT + ROS 2 with honest deployment benchmarks I’ve released LaserPerception v0.1.0 , an open-source LiDAR deployment project focused on reproducible PointPillars/TensorRT/ROS 2 inference rather than model training.

Hola a todos, estoy explorando un problema que creo que puede resultar interesante para quienes trabajan con ROS 2, VLA/VLM, embodied AI, visión por computador y manipulación robótica. El contexto es un viñedo. La pregunta no es simplemente: ¿cómo automatizamos la poda u otra operación? La pregunta que me interesa es más profunda: ¿puede un robot observar una vid, comprender su estructura y contexto, interpretar un objetivo definido por una persona y aprender progresivamente cómo intervenir, en

Ciao a tutti, sto esplorando un problema che penso possa essere interessante per chi lavora con ROS 2, VLA/VLM, embodied AI, computer vision e robotic manipulation. Il contesto è un vigneto. La domanda non è semplicemente: come automatizziamo la potatura o un’altra operazione? La domanda che mi interessa è più profonda: può un robot osservare una vite, comprenderne struttura e contesto, interpretare un obiettivo dato dall’uomo e imparare progressivamente come intervenire, invece di eseguire sola

So, current issue of the launching VLAs on the Humanoids, like G1 Unitree\EngineAI T800\another, is the realsense pack of cams. F.e., for the unifolm vla ( GitHub - unitreerobotics/unifolm-vla · GitHub ), you need 2 on wrists + 2 on shoulders, so its kinda there is no another way without realsense? Currently kinda stuck on this type of the issue, maybe someone know the solution? 1 post - 1 participant Read full topic

So it is time for another Swedish ROS meetup! The Nordic Techweek is coming soon to Stockholm and with the Physical AI Day planned on the Tuesday afternoon. So of course we will need to properly startup the day to get our fellow ROS developers together! So together with Scailabs ( @ljdust ) and McGuire Robotics ( @kimmcg ) we will organize a 2 hour ROS developer meetup at MagasinX . Date: Tue, Sep 8, 2026 8:00 AM UTC → Tue, Sep 8, 2026 10:00 AM UTC Place: MagasinX , Tullvaktsvägen 9, 115 56 Stoc

Hello Gazebo Community, We want to highlight an important bug fix and subsequent behavior change in the AdvancedLiftDrag system, recently addressed in Issue #3695 . What was the issue? Previously, when computing the pitching moment coefficient ( Cem ) in AdvancedLiftDrag.cc , the alpha-based pitching moment (derived from Cem0 , Cema , and CemaStall ) was unintentionally being overwritten by the sideslip contribution. Because the code used an assignment instead of an accumulation, the previously

One of the most common questions we get is some version of “how do I start contributing?” Here is a concrete answer: join us for Waffle, Thursdays, 30 minutes. What it is Waffle is a weekly triage meeting. We go through the issues and pull requests coming into the ROS 2 repositories that nobody has picked up yet, and we quickly discuss, triage, and assign them. It moves fast. Most items get a minute or two: what is this, is it valid, who should look at it. We assign things live in the meeting ra

The ROS PMC meeting for this week was on Tuesday, August 11, 2026. The notes from the meeting are available at ROS PMC weekly meeting agenda . ROS PMC Business Funding proposals update. Discussion is ongoing and nothing has been decided yet. The working consensus favors directing most of the money toward CI infrastructure. Target is to have this settled before ROSCon so it can be announced there. Execution largely sits with the Infrastructure PMC and OSRF rather than this PMC, with ownership del

Hi everyone! I recently finished a robotic tracked platform that I developed as an engineering graduation project. The goal was to build a functional mobile robot combining mechanical design, embedded control, radio communication, and basic computer vision. The platform includes: 3D-printed tracked chassis designed in SolidWorks Arduino Mega 2560 for real-time motion control BTS7960 motor drivers FlySky FS-i6 / FS-iA6B radio control via iBus Differential track steering Two-speed transmission Ras

RoboParts — Structured Dataset & Selection Engine for Bionic Robot Components Hi ROS community, We’re building RoboParts ( https://roboparts.cc ), an open structured dataset and online selection engine covering the hardware stack for humanoid / bionic robots. Sharing it here because ROS 2 compatibility is one of the dimensions we track — and because we’d like feedback on how we handle missing data, which turned out to be the hardest part. What is RoboParts? A curated, structured dataset of 708 e

A few weeks ago @jopequ shared mcp-rosbags + mcp-lab ( Another MCP Server to analyze your rosbags with LLMs + a UI to benchmark it against different LLM providers ) — an MCP server with purpose-built analysis tools (trajectories, laser scans, tf, plotting) and a neat UI for benchmarking providers on it. We’ve been working on the same problem at Pixel Robotics (AMRs for pallet transport) and just wrote up our approach, which lands on a different point in the design space, so I thought a compariso

Did someone already do something regarding simulating latency (or even jitter) in sensor data and control commands? I think the obvious approach when you work with ROS is to implement something like topic_tools/delay and plug it behind the bridge. However, that seems to massively increase the number of topics, making it very error-prone to pick the right one… I can imagine a similar mechanism on the gz-transport side, that would at least help with the number of ROS topics. But isn’t there someth

Hi everyone, I’m looking for a robotics engineer for a paid 4–6 week prototype project based in Hamilton, Ontario, Canada. The immediate goal is deliberately narrow: build a household manipulation prototype using an off the shelf robotic arm, cameras, and teleoperation to reliably move a standardized plate, bowl, and cup from fixed starting locations into predetermined dishwasher-rack locations. The initial work would include: selecting/recommending an appropriate off the shelf arm arm bring up

Hi everyone! I posted an early version of rostree on reddit a while back, around 0.2.2… but never here. Three releases later it’s at 1.0, and enough has changed that a fresh post seemed more honest than a bump comment. It answers the questions you actually ask about a workspace: what does this package pull in, who depends on it, why is this thing in my tree at all, and what changed since my last build. CLI, TUI, Python API. pip install rostree source /opt/ros/<distro>/setup.bash # and/or your wo

Have you ever set up dominoes for a truly epic fall ? There’s a whole lot of setup that precedes an impressive end result . That’s what it felt like in Open Robotics HQ this past week. So many of the things we do take a lot of work and yak shaving before they show any results. Sure, those results can be impressive , but that setup…you need to keep reminding yourself that you are making progress, even if it doesn’t feel that way. You’ve all been there and know the feeling. In the past week we’ve

So I went into a bit of a rabbit whole last week! CI on windows kept on getting this particular error: 2: [WARNING] [python.exe-2]: 'SIGINT' sent to process[python.exe-2] not supported on Windows, escalating to 'SIGTERM' Apparently, windows does not have a proper way to handle SIGINT, which means that it always straight goes to the ungraceful shutdown of SIGTERM. So I thought “oh! is that perhaps the reason why we keep getting all of the unhandy access violation ( 3221225477) that we see ever si

Hello Community! Here’s the information for our next August Meeting where we’ll talk about running reinforce learning algorithms using Gazebo. “Gym Gazebo Sim is an educational software toolkit developed to help beginner Gazebo users use the Gymnasium API by the Farama Foundation for reinforcement learning. The toolkit was developed for an introductory course for Gazebo Sim, ROS 2, and RL. It simplifies development for students by providing a base class to pause, resume, and step the simulation,

Hi everyone, I’d like to share my first complete autonomous mobile robot project: an Autonomous Warehouse AMR simulation built with ROS 2 Jazzy, Gazebo Harmonic and Nav2 . The robot is a differential-drive AMR equipped with a simulated 2D GPU LiDAR and can autonomously navigate inside a warehouse environment using: AMCL for localization robot_localization EKF for odometry / TF SmacPlanner2D for global path planning Regulated Pure Pursuit for path tracking Local and global obstacle-aware costmaps

Hi Open-RMF team, I am currently investigating the Beacon functionality in Open-RMF / RMF Web, especially rmf_fleet_msgs/BeaconState and the beacon_state topic. I found the BeaconState message definition, the beacon handling code in rmf-web , and some unit tests for the beacon dashboard components. However, I could not find documentation explaining how extensively the Beacon functionality has actually been tested or used. I would like to clarify the following: Have Beacons in Open-RMF been teste

Hi everyone, I’m a PhD student, and after a few years my codebase has grown quite a bit, spread across different git repos, Docker containers, and machines. I knew it would be good to add some tests to avoid regressions and losing work or features. However, writing unit tests alone as a student would probably cost me another year of my PhD. So instead I went for integration tests, which are easier to write in a ROS environment and make more sense for a pipeline where the internal functions keep

I am prototyping **EdgeAI Forge**, a local-first engineering architecture intended to help generate, test, benchmark, and document ROS 2 and machine-vision pipelines. The initial target workflow is a ROS 2 vision pipeline generator. Given a requirement such as: > Read frames from a USB camera, run object detection, publish detections, expose health status, benchmark performance, and prepare deployment to Jetson. the system should eventually produce reviewed artifacts including: - package manifes

Hi everyone! I’m a 2nd-year Mechanical Engineering student at NIT Jalandhar, currently exploring Robotics and Automation. I’m starting my journey with C++/Python, electronics, CAD and eventually ROS 2. My long-term goal is to work on real robotics projects and eventually pursue research/internship opportunities in robotics. I’m looking to connect with: • Students who are also learning Robotics/ROS 2 • People working on interesting robotics projects • Researchers/engineers who are open to collabo

Hi all, I’m an MEng Robotics & AI student at UCL working on perception/tracking pipelines (recently built a person re-ID and tracking evaluation pipeline, and a Gaussian-splat reconstruction quality evaluator). I’m trying to understand a specific problem better: how do teams currently notice when a perception or sensor-fusion stack has silently degraded in production, before it causes a visible failure? Do you rely on manual spot-checks, logging + alerts, a formal calibration schedule, or someth

I’m a 4th-year Computer Engineering student in Palestine (Birzeit University, graduating 2027). I focus on embedded systems and robotics. I have US citizenship, but I never lived or worked in the US. There’s no embedded or robotics industry here at all, so I can’t really build experience or a network locally. I’m trying to move to the US, but I’m not sure where to start. My background: ROS2 control software for a multi-agent robotics platform, FreeRTOS firmware on custom boards, and a competitio
