For industrial robotics teams, simulation is useful only when the important parts of the simulated system behave enough like the real system to support better engineering decisions. A robot arm that looks right but reaches to the wrong pose is an obvious problem. A gripper that looks right but responds differently during contact can be harder to notice, and in manipulation work it may matter even more. At Southwest Research Institute, we have been developing and evaluating Physical AI approaches

[Update] Thanks to the great feedback in the comments regarding rosbag2 snapshot , I have updated the original post to clarify how YERP and rosbag2 snapshot work perfectly together as a trigger-and-capture pair! Hi everyone, Recently I have been thinking about a very practical debugging problem in ROS / ROS2 perception pipelines, especially for AMRs and mobile robots. When a robot behaves strangely in the field, the usual workflow is often: rosbag record everything. Bring the massive data back.

Hi everyone, Recently, I’ve been learning more about Zenoh and its role in the ROS 2 ecosystem. Since most ROS 2 applications rely on DDS for communication, I was curious about how Zenoh approaches the same problem and where it can provide advantages. From what I’ve learned so far, Zenoh offers a lightweight communication layer that aims to reduce latency, minimize bandwidth usage, and simplify communication across distributed systems. These characteristics make it particularly interesting for r

Just saw that newly imported Chinese legged and humanoid robots are now banned in USA , what other alternatives are there? I know Unitree had ROS interface in both Go2 dog and G1 humanoid (and you could jailbreak cheap base version instead of expensive research one). What other alternatives are there? Will this spur open source/open hardware design? Again, I’m adding poll of what legged/humanoid robots have you used/planned to use What legged/humanoid robots have you used/will use? Chinese( Un

Hello ROS Community, The OSRF Infrastructure Project is planning to update the Jenkins version of https://build.ros2.org as part of our ongoing efforts to maintain and improve the ROS buildfarm infrastructure. To facilitate this migration, the following services will experience downtime during the maintenance window: https://build.ros2.org (Jenkins) will be temporarily unavailable or in shutdown mode (not running jobs). The migration is scheduled to begin on Monday Mon, Aug 3, 2026 11:30 AM UTC

Hi everyone, I’m curious about how other ROS 2 developers approach understanding a large or unfamiliar workspace. When joining an existing project or reviewing a large codebase, I often find myself asking questions like: Which packages depend on each other? Which nodes communicate together? What topics, services, and actions are used? Are there isolated nodes or communication issues? Does the implementation still match the intended architecture? How do you quickly get a high-level understanding

Hi all, I’ve been working on a global planning engine aimed at warehouse/fleet deployments, and I just opened a free API tier. I’d love feedback from people running real Nav2 fleets. What it does You upload an occupancy grid once. It solves a field for your goal (charging station, pick station, dock), and from then on every path query — from any start cell — returns a strictly optimal path in microseconds, without re-searching the map. The pitch for fleet operators: the cost of global planning s

TL;DR : A workspace-level uv-managed venv works on stock apt-installed ROS 2 — including a PyTorch+CUDA node — but we hit five reproducible failure modes on the way (verified on Jazzy; none of the mechanisms are Jazzy-specific). Key measurement: the known shebang workaround ( [build_scripts] executable = /usr/bin/env python3 ) does not cover --symlink-install , so when colcon is launched from the system Python there is currently no complete workaround. Below are four minimal change proposals for

We have been working on adding real-time functionality to rcl and rclcpp since 2022. In response to this proposal, we have created a new package that provides real-time functionality without changing the existing packages. esol-community/ros2_realtime_support Background The previous discussion is as follows: ROS lacks a unified mechanism to formally support real-time functionality, and we have tried to achieve this by adding functionality to rcl and rclcpp . On the other hand, it has been pointe

Hi ROS Community! We are opening early-access evaluations for ADEL 2.0 (Autonomous Deterministic Executive Layer), a bare-metal C++/Rust execution engine built for ultra-low latency, zero-jitter control loops. While designed for microsecond satellite maneuver planning under severe compute bounds, ADEL 2.0 provides immediate utility for terrestrial robotics, BVLOS drone flight controllers, and autonomous hardware running ROS/ROS2 node topologies. Key Highlights: Microsecond-latency spatial trajec

Hi ROS Community! For years, there has been a strong and consistent demand for seamless Protobuf serialization in ROS/ROS 2. While there are excellent existing tools in the community, integrating them cleanly into a high-performance, production-ready pipeline often comes with friction. Today, we’re excited to introduce protoros2 — a middleware wrapper and orchestration engine designed to provide zero-intrusive protobuf support for ROS 2. ZhenshengLee/protoros2: use protobuf in ros2 without compr

I briefly mentioned an order-sensitive state diagnostic in another thread, but that was the wrong place for it. Posting it separately here with an executable reproducer. The idea is simple: three consecutive pose samples in, one scalar residual out. It quantifies how much the result shifts when you change the nesting order of state composition. Synthetic test results: Smooth linear motion: 4.9848e-08 Abrupt pose/orientation jump: 0.000881456 This is absolutely not a validated anomaly detector ye

I have been looking into rosidl::Buffer and the current buffer backend support, particularly for large variable-length payloads such as images and point clouds. One idea I am interested in is a CPU shared-memory backend for rosidl::Buffer . I realize that this overlaps to some extent with functionality that already exists at lower layers. For example, some middleware / RMW implementations already provide shared-memory transport or other zero-copy optimizations. Depending on the implementation, m

I’ve been working on a ROS2 Dev Container Feature and just updated my VSCode ROS2 Workspace Template to use it instead of my pre-built ROS Docker images. The feature is here: GitHub Build software better, together GitHub is where people build software.

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

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

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

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

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 ROS & Gazebo Community, We’re excited to announce the release of gz_ros_tts, an open-source ROS 2 Text-to-Speech (TTS) Plugin for the latest Gazebo Harmonic. This release is the Gazebo Classic and Gazebo harmonic ROS TTS Plugin, bringing the same idea to the modern Gazebo ecosystem with ROS 2. # Project Evolution ## Version 1 — Gazebo Classic ROS TTS Plugin The first version of the plugin introduced Text-to-Speech support for robots running in Gazebo Classic through ROS. ### Supported

Hello, I was working on a Embodied Agent project in University for last 9 months. The problem is we are using a regular VLM + algorithmic methods to make the robot understand its environment and do missions given by the user. I was misdirected into creating a project that would require a large team and big budget, if this project’s idea would be even considered valid. At the beginning we thought this could be done and cheap AMR’s could benefit from it without data training like humanoid robots.

I’ve always put just “BSD” in the package.xml of our projects, mostly because it is the exact value mentioned in https://www.ros.org/reps/rep-0149.html#license-multiple-but-at-least-one . However, this value is not SPDX. What’s the current best practice? Should we start putting SPDX identifiers into the license tag? Would it deserve a small update of REP 149? 11 posts - 5 participants Read full topic

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

Over the past few months, I've had the privilege of stepping into the role of leading ROS-Industrial Americas. I'm grateful to Matt Robinson for his years of leadership and the strong community he helped build. At our 2026 Annual Meeting, I had the opportunity to share my first impressions and my vision for where we can go next. I've reproduced that welcome letter below, because it captures the direction I hope we'll pursue together. This is my first annual meeting as program director for ROS-In
