ROS Discourse General: VectorField Planner: 7 µs global path queries with strict optimality — REST API for occupancy grids, Nav2 plugin on roadmap
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 stops scaling with
the number of robots.
Measured numbers (C++ core, single thread, low-end 2-core CPU)
1M-cell 3D warehouse map (100³, mezzanine floors + rack walls):
| Metric | VectorField | A* (C++, typical) |
|---|---|---|
| One-time solve per goal | 47 ms | — |
| Query, any start pose | 7 µs | ~5 ms, every query |
| Optimality | 1.0000 (BFS-verified) | optimal |
| Peak memory | 5 MB | — |
| 10,000 simultaneous queries | 70 ms total | ~50 s |
Dynamic sites: obstacle removal (cleared shelves, opened gates) is patched
exactly, 5.9× faster than a rebuild, zero error. Every solve is a fixed,
bounded number of identical array operations, so worst-case latency is known
in advance — relevant if you need timing guarantees for certification.
Where this fits in a ROS stack
- Input: an occupancy grid (the same data you already publish on
/mapor
keep in acostmap_2dlayer) - Output: an optimal cell path per query
- Today: plain REST API, so anything that can HTTP can plan. A native Nav2
global-planner plugin (drop-in replacement for Navfn) is on the roadmap —
the field-reuse model maps nicely onto multi-goal / fleet planners, which is
exactly where Navfn recomputes the most.
Typical integration I’m picturing: your fleet manager uploads the map once per
shift (or per layout change), then every robot’s global plan request is a
~7 µs lookup instead of a Navfn re-search.
Honest limitations
- Built for structured, mostly-static environments — warehouses, factories,
indoor drones. Not for highly dynamic unstructured spaces. - Obstacle insertion currently uses a repair fallback; exact fast insertion is
roadmap work. - It’s a hosted API (with an on-prem license option), not an open-source
package. Free tier is genuinely free: 100³ maps, 1,000 solves + 100K
queries/month.
Links
- Live browser demo (races the solver against A*, no sign-up):
https://vectorfield.top - Free API key (instant): https://vectorfield.top
- API docs: VectorField Planner API - Swagger UI
Questions I’d especially love feedback on:
- For those running multi-robot fleets: how do you handle global replanning
cost today? Is 5 ms/query/robot actually hurting you, or is local planning
the real bottleneck? - What would a Nav2 plugin need to do for you to consider it (topic/action
interface, costmap update cadence, multi-goal support)? - Any interest in an on-prem / offline deployment for sites without
connectivity?

ROS Discourse General: How do you understand the architecture of a large ROS 2 workspace?
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 before running the system?
I’m interested in learning about your workflow.
For example:
- Which tools do you use?
- Do you rely mostly on runtime tools such as
rqt_graph, Foxglove, or RViz? - Do you have internal scripts or documentation that help?
- Do you manually inspect the source code?
- Do you perform any kind of static analysis before launching the system?
- How do you review architectural changes in CI?
I’m particularly interested in workflows for medium-to-large industrial projects where a workspace may contain dozens (or even hundreds) of packages.
Looking forward to hearing how everyone approaches this problem and what has worked well in practice.

ROS Discourse General: Jenkins version upgrade of build.ros2.org [Scheduled Buildfarm Downtime]
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 (11:30 UTC) and is expected to last for 4 hours. During this time, the buildfarm will be offline, and all queued jobs will need to complete before Jenkins is taken offline.
Once the upgrade is complete, I’ll update this thread to confirm that services are back online. I’ll also be monitoring for any issues that may arise as a result of the upgrade.
Thank you for your patience as we work to improve the ROS buildfarm infrastructure. If you have any questions or concerns, please feel free to reach out in this thread.
Att,
Cristóbal

ROS Discourse General: Learning Zenoh: A New Communication Layer for ROS 2
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 robots running on resource-constrained hardware such as the Raspberry Pi or for systems that need to communicate across different networks.
I’m currently developing a mobile robot called Pavlov Mini Wheel, based on ROS 2 Humble, and I’m planning to experiment with Zenoh for communication between the onboard Raspberry Pi and an external laptop running perception and navigation workloads. It seem like an interesting opportunity to compare its behavior with the default DDS-based setup.
This post is the first step in my exploraiton of Zenoh. Over the next few weeks, I plan to document:
- Installing Zenoh with ROS 2 Humble
- Integrating Zenoh into a existing ROS 2 project
- Comparing DDS and Zenoh in practical robotics scenarios
- Sharing performance observation from a real robot
If you’ve already used Zenoh in your projects, I’d be happy to hear about your experences, recommendations, or challenges you’ve encountered.
My article on the relevant topic:

ROS Discourse General: YERP + rosbag2 snapshot: can we capture why a ROS perception latency spike happened?
[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 recordeverything.- Bring the massive data back.
- Replay it and try to find what happened.
Of course, rosbag2 is powerful. I am also aware of rosbag2 snapshot mode, which can keep recent messages in memory and dump a raw topic window when triggered. That is actually very close to the architecture I have in mind. I do not want to replace rosbag2 or its snapshot mode. Instead, I want to explore a lightweight layer above it: an event-triggered Runtime Evidence Layer for ROS perception pipelines.
I call the current prototype YERP — originally “YOLO Edge Runtime Profiler”.(Project repo: https://github.com/ZC502/yolo-edge-runtime-profiler)*
The core idea
In my view, the layering could be:
-
rosbag2 snapshot: captures the raw ROS topic window.
-
YERP / EvidenceFlow: decides when the snapshot is worth triggering, records why it was triggered, and adds structured perception-runtime evidence.
So the question is not: Can YERP replace rosbag2? The question is: Can YERP act as the lightweight anomaly detector / evidence sidecar layer that triggers rosbag2 snapshot at the exact right moment?
For example, a robot may run normally most of the time, but occasionally:
- average FPS looks fine, but p95 / p99 latency spikes
- the local planner receives perception results too late
- a detection frame creates too many candidates
- postprocess suddenly dominates runtime
- the issue is hard to reproduce later
In that case, raw topic replay is useful, but we also need to know:
- Why was this moment captured?
- Which frame was involved?
- Which perception stage became slow? (preprocess, inference, postprocess, callback delay, queue delay, or message age?)
- Did output pressure increase? Was there a box-count or candidate-count spike?
That is the role I am exploring for YERP.
Current prototype status
The current YERP Vision prototype has already been tested in a standalone YOLO / edge CV pipeline. It can monitor fields such as preprocess_ms, inference_ms, postprocess_ms, p50/p95/p99 latency, box count, and confidence entropy.
When a runtime pressure event is triggered, it saves local evidence (image.jpg, metadata.json, etc.).
In one test case, a normal-looking YOLO frame was captured not because it was manually labeled as a “[bad frame] ”, but because the runtime trace showed pressure:
{
"state": "RED",
"dominant_cause": "POSTPROCESS_DOMINANT",
"selection_reason": "runtime_pressure",
"metrics": {
"box_count": 18,
"class_count": 4,
"confidence_entropy": 2.51,
"preprocess_ms": 1.20,
"inference_ms": 3.95,
"postprocess_ms": 2.02,
"postprocess_ratio": "28.15%"
}
}
The important point is not that the image “looks abnormal”. The important point is: this input frame created measurable runtime pressure, so it became worth saving as evidence.
Community Momentum
This concept is already gaining cross-community traction:
-
I have introduced this EvidenceFlow approach in the Ultralytics GitHub Discussions, where the team is currently gathering feedback.
-
I’ve also initiated an open co-testing discussion within the MindSpore Lite community, and developers there are exploring collaboration for edge NPU inference.
Now, I want to bring this discussion to the ROS ecosystem, which is arguably where field debugging is the most painful.
EvidenceFlow Schema v0.1 Draft
Instead of exposing all internal YERP logic, I am thinking about a simple structured sidecar format. A ROS / ROS2 runtime pressure event could look like this:
{
"schema_version": "0.1",
"record_type": "runtime_pressure_event",
"sample": {
"sample_id": "frame_1048",
"input_ref": "/camera/front/image_raw",
"timestamp": "2026-07-27T19:32:18.104Z"
},
"environment": {
"runtime": "ros2",
"backend": "yolo_edge_runtime",
"mode": "event_only",
"device": "amr_edge_board"
},
"trigger": {
"state": "RED",
"reason": "latency_p99_spike",
"observed_ms": 51.7,
"threshold_ms": 30.0,
"dominant_cause": "POSTPROCESS_DOMINANT"
},
"stage_ms": {
"preprocess": 2.1,
"inference": 15.4,
"postprocess": 34.2,
"total": 51.7
},
"ros_metadata": {
"topic": "/camera/front/image_raw",
"node": "/perception/yolo_detector",
"callback_delay_ms": null,
"queue_delay_ms": null,
"message_age_ms": null,
"dropped_messages": null
},
"output_metadata": {
"box_count": 145,
"candidate_count": 312,
"confidence_entropy": 2.8,
"class_entropy": 1.4
},
"hardware_metadata": {
"cpu_usage": null,
"gpu_usage": null,
"npu_usage": null,
"memory_spike_mb": 12,
"temperature_c": null
},
"snapshot": {
"rosbag2_snapshot_triggered": true,
"window_sec": 5
},
"privacy": {
"local_first": true,
"image_saved": true,
"upload_performed": false
}
}
The goal is not to force every ROS project to use these exact fields, but to discuss what a useful runtime evidence record should contain.
Runtime Overhead
A natural concern is: Will such a probe slow down the robot?
Absolutely valid. A probe should not become the new bottleneck. The design separates the workload:
-
Fast path (Main inference loop): read existing timestamps, update a fixed-size rolling window, check trigger conditions. No file IO, no large tensor copies, no image saving.
-
Slow path (Background worker): after a trigger, write JSON / image in a background worker, and optionally call rosbag2 snapshot service. Uses a bounded queue and drops evidence if full to avoid blocking inference.
For production ROS / ROS2 systems, the default modes would likely be shadow_mode (observe only) or (write only when triggered).
How I imagine the rosbag2 integration
-
Observe: YERP observes perception timing and output metadata.
-
Detect: YERP detects a runtime pressure event (p99 spike, queue delay, output pressure, etc.).
-
Log: YERP writes a small EvidenceFlow JSON sidecar.
-
Trigger: If raw replay is needed, YERP calls
rosbag2snapshot service. -
Result:
raw bag window+structured reason for capture+perception-stage timing+output metadata.
In short: rosbag2 snapshot tells us what raw ROS messages were around the event. YERP / EvidenceFlow tells us why this event was worth capturing.
Questions for the ROS community
I would really appreciate feedback from people who debug ROS / ROS2 robots in the field.
-
Does this EvidenceFlow schema cover the information you would want when debugging ROS perception latency?
-
For ROS2, should such an adapter start at the image topic level, diagnostics level, or executor / callback timing level?
-
For AMR / mobile robot scenarios, which fields matter most? (
frame latency,message age,queue delay,callback delay,TF wait time, etc.) -
How do you currently trigger rosbag2 snapshots in real robots? (Manual trigger? Diagnostics threshold? Topic frequency monitoring? Custom anomaly detector? Lifecycle event? Nav2 state?)
-
Would a small structured JSON sidecar make snapshot bags easier to triage later?
Boundary
To avoid misunderstanding:
-
YERP is not a replacement for rosbag2.
-
YERP is not a replacement for tracing or profilers.
-
YERP does not identify the final root cause by itself.
-
YERP tries to capture the input frame and runtime metadata that make a case worth investigating.
My current goal is to turn field debugging from “record everything and search later” into “capture structured evidence when runtime pressure actually happens”.
I am sharing this as an early prototype and schema draft. Comments, criticism, field stories, and suggestions are very welcome!
If you find this “Runtime Evidence Layer” concept valuable for your edge AI ROS deployments, or if you are interested in co-designing the ROS2 adapter together, feel free to drop a comment below, open an issue on GitHub, or reach out to me directly!

ROS Discourse General: What should go in the tag?
I’ve always put just “BSD” in the package.xml of our projects, mostly because it is the exact value mentioned in https://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?

ROS Industrial: A New Chapter for ROS-Industrial Americas
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-Industrial Americas, and one thing has become clear very quickly: the strength of ROS-Industrial has never been a single individual or organization. It's the community itself.
Since we announced the leadership transition, I've heard from dozens of members offering encouragement, advice, questions, and ideas.
You made it immediately obvious that you participate in ROS-Industrial not because of a logo or affiliation, but because you genuinely care about advancing industrial robotics. That commitment matters especially now.
It feels like a lot has changed since our last meeting a year ago. Large language models have rapidly evolved from impressive demonstrations into practical tools used daily by engineers around the world. Those same advances are now beginning to reshape robotics as well.
Major technological shifts create uncertainty, but they also create opportunity. One of the reasons ROS-Industrial exists is to help practitioners evaluate emerging technologies, separate signal from noise, and move useful ideas from research into real-world deployment.
For fourteen years now, ROS-I has helped industrial robotics practitioners advance, adopt, and apply technologies that were once difficult to deploy reliably in industrial contexts. Today, we're seeing another transition. Robotic foundation models, LLMs, Physical AI, synthetic data generation, and learning-enabled systems are creating capabilities that seemed impractical not many years ago.
The question for us is no longer whether these technologies will influence industrial robotics. As we will hear from several speakers, they already have. The question is how we incorporate them responsibly, effectively, openly, and practically into real systems.
As I step into this role, I see part of my responsibility as helping this community ask those questions clearly and answer them together.
ROS-Industrial's mission remains the same: enabling innovation in industrial robotics through collaboration, open-source technology, applied research, and education. New technologies will continue to emerge, and our responsibility is to understand them, evaluate them, and make them useful to industrial practitioners. Today, that includes AI. Tomorrow, it will include technologies not yet imagined.
I am grateful to inherit that mission, and I am committed to stewarding it with diligence, openness, and practical focus.
At this year's meeting, our speakers will introduce new open-source robotics software, explore novel applications of AI, discuss new opportunities for open-source automation, and share real-world experience deploying these solutions in specific contexts. Our workshops will give you a focused opportunity to direct the consortium over the coming years.
But the future of ROS-Industrial will not be determined by keynote speakers, steering committees, or roadmap documents alone. It will be shaped by practitioners who bring real problems, real deployments, real successes, and even real failures back to the community.
I offer my sincere thanks to every one of you and your colleagues who have fed this community over the last year: contributing code, sharing lessons learned, participating in projects, mentoring newcomers, and helping move open-source robotics technology from research into production.
I'm excited about this meeting, but I'm more excited about what we'll all do together in the year ahead.
Sincerely,
Jerry Towler
Program Director, ROS-Industrial Americas
ROS Discourse General: Do warehouse AMR operators actually monitor their fleets for security in production?
Hi all — I’m a security engineer researching runtime security for autonomous mobile robot fleets (warehouse/3PL AMRs on ROS 2). I keep hitting one question I can’t answer from the outside, and I’d value the perspective of people who actually run or build these fleets:
- For fleets already deployed in production — is anyone doing continuous security monitoring (detecting anomalous behaviour at runtime), or is security still mostly design-time hardening (SROS 2, DDS security) and then hands-off?
- When an operator worries about a robot being compromised, is that framed as a cybersecurity problem or purely as a safety/uptime problem? Who owns it internally?
Not selling anything — genuinely trying to understand the current state before assuming a gap exists. Grateful for any real-world experience.

ROS Discourse General: Convert in the terminal
Would you use a free CLI tool to convert CAD assemblies to URDF?
No CAD plugins.
Just one command from your terminal to work in Ros directly.
I’m thinking about open-sourcing the core of a tool I’ve been building over the past few months, and I’d love to validate the idea before releasing it.
Would you use something like this?
Or do you prefer the existing CAD add-ins?
If not, what’s the biggest reason?

ROS Discourse General: Seeking advice on reaching ROS 2 developers
I’ve spent the last few months building ������� to automate one of the most repetitive parts of robotics development. Instead of manually converting CAD assemblies, configuring joints, generating robot descriptions, and debugging the first setup, the goal is a verified, ready-to-use robotics workspace automatically in ������ and ����.
But now I’m at a point where the technical part feels solid. The new challenge is figuring out how to reach the right users for such a ��������� �������.
If you’ve built developer tools or engineering software, how did you get your first 10 to 50 users? What channels actually worked? What wasted effort would you skip if you started again?

ROS Discourse General: Community event calendar; Get updates to only the selected events
On the community event calendar (introduced in discourse.openrobotics.org#48220), is there a way to 1) select only the events of my interest, 2) receive updates if such event gets updated (time change etc.)?
- Each event seems to offer “Copy to my calendar”, which does copy a particular event on to my calendar, but the event doesn’t seem to get updates from the original event entity. Also even if the original event is recurring, the copied event seems to be one-time.
- Choosing “Add to Google Calendar” option adds this entire community event calendar to my calendar, which shows all events, not just the ones of my interest.
- The idea of aggregating the community events at a single location is great!!! It’s just on my personal calendar, having all events would be simply too much, so would like to be selective.
Thank you.

ROS Discourse General: Nvidia Jetson price increase by up to 100%, what other boards are you using to run ROS?
As avid Jetson user, I just saw there has been 50-100% price increases across all Nvidia Jetson kit/module lineup, what other boards/SoCs/PCs are you using for running ROS on real world robots? I saw recent posts by @smac with AMD Strix, Intel also made some robotics computers recently, there’s also upcoming Qualcomm’s Arduino HW, but that’s more on EDU/DIY side…
Jetsons seemed to me to have the most mature ecosystem, but some of those price increases surely puts them away from reach of students/hobbyists, and can have also impacts on larger fleet deployments.

ROS Discourse General: PyZeROS: a Python-first alternative to `rclpy` over Zenoh
Hi everyone,
I am releasing PyZeROS, an experimental alternative to rclpy for communicating with ROS from Python. This is not a Python wheel packaging rclpy: I bit the bullet and wrote a client from scratch in pure Python.
You can install PyZeROS like a standard python package:
pip install pyzeros
It does not require a ROS installation, colcon workspace, message compilation, or a ROS executor. It communicates with ROS 2 through Zenoh and interoperates with standard ROS 2 nodes using rmw_zenoh_cpp.
The main features are:
- Interoperability with
JazzyandLyrical - Designed for
asyncioand asynchronous Python - Topics, services, and QoS
- Custom ROS messages defined directly with Python classes
- Installation through
pipwith minimal dependencies
A subscriber looks like this:
import asyncio
import asyncio_for_robotics as afor
import pyzeros
from ros2_pyterfaces.cyclone.all_msgs import String
async def main():
sub = pyzeros.Sub(String, "chatter")
async for msg in sub.listen_reliable():
print(msg.data)
with pyzeros.auto_context(node="listener", namespace="/demo"):
asyncio.run(main())
Why another ROS 2 client?
You’ll find that Rust has many independent ROS 2 client implementations, all with interesting designs and trade-offs. In Python, however, we have only rclpy, and RoboStack+Pixi as (fantastic) alternative installation method.
I made PyZeROS as a Python-native option built around standard Python tooling and asyncio. It’s not a repackaging of rclpy or rcl and is widely different from it. The goal is to communicate with a ROS network from python, not to integrate with the whole ROS ecosystem.
Main differences are:
- PyZeROS installs through
pip, so it should work easily with standard isolated-environment tooling likevenv,uv,pipx,uvx,pixi. - It is primarily coded in python so no additional
colcon buildto compile a message types. And Python developers can dive into the source code. - It uses standard Python tools and small dependencies. It should run mostly anywhere.
- PyZeROS deliberately does not aim to support every ROS feature. The Python ecosystem is prioritized:
argparsefor configuration,subprocessfor launching processes, andimportlib.resourcesfor shared package data. asynciois the primary executor.
Why asyncio?
Robots are asynchronous systems, so they need an execution model. Python already has one: asyncio, so I use it.
Using callbacks directly is possible, but it can quickly lead to shared-state issues, locks, and complicated lifecycle management. After using asyncio in robot applications for several years, I find async/await much easier to reason about, and the python community has many tools for it. In my benchmarks, PyZeROS is also significantly faster than rclpy’s callback-and-executor model, so there does not appear to be a large performance hit from asyncio.
Custom messages
This is essential to ROS, and making them easy to define was especially important to me. In PyZeROS, you can define them directly as Python dataclasses and interoperate with standard ROS 2 messages:
from dataclasses import dataclass, field
import pyzeros
from ros2_pyterfaces.cyclone import all_msgs, idl
@dataclass
class Sphere(
idl.IdlStruct,
typename="tutorial_interfaces/msg/Sphere",
):
center: all_msgs.Point = field(default_factory=all_msgs.Point)
radius: idl.types.float64 = 0.0
pub = pyzeros.Pub(Sphere, "sphere")
pub.publish(Sphere(radius=42.0))
There is no .msg file, CMake configuration, or colcon build required on the PyZeROS side. For interoperability, the type name, field names, and field types must match the message definition used by the other ROS 2 nodes.
Performance
I also measured PyZeROS against rclpy for round-trip latency:
- PyZeROS: ~13 µs
rclpywithSingleThreadedExecutor: ~70 µs
This is about 5.5× faster in this microbenchmark.
The benchmark sends sensor_msgs/msg/JointState messages continuously inside one node using two publisher/subscriber pairs. Keeping everything local minimizes transport latency, so the benchmark primarily measures executor and message serialization/deserialization overhead.
The benchmark code and complete results are available here: GitHub - 2lian/afor_benchmarks · GitHub
I also tested PyZeROS in a more realistic stress test with 100 nodes publishing mostly JointState messages at around 10 Hz. This uses my own ROS nodes for controlling a robot swarm that I have been working on for several years. In that application, the PyZeROS version used roughly one-quarter of the CPU used by the rclpy version.
Related libraries I created for PyZeROS
ros2-pyterfaces is how I define messages in Python. It provides XCDR1 serialization and ROS RIHS01 type hashes. It can serialize using cyclone_idl (tweaked by me) or cydr (created by me), with cydr being faster than rclpy to ser/de messages. It is a standalone low-level library, so it can also be used independently to send ROS messages over DDS or another RMW:
asyncio-for-robotics (afor) is the asynchronous model that I’ve been using on my robot software for a while now. It already supports ROS (rclpy) and other systems, and it now supports Lyrical and its new AsyncNode:
Feedback, testing, issues, and contributions are very welcome. I am sure there are still some rough edges, but I cannot wait indefinitely for perfection before releasing it. Reaching this point took a long time. ROS is a large ecosystem, and I am already very happy to have topics and services working

ROS Discourse General: OnSLAM: Run LiDAR-inertial mapping on ROS1 bags directly from Windows
Hi everyone,
I recently released OnSLAM, an open-source Windows application for running LiDAR-inertial odometry and mapping on ROS1 bag files.
It automatically detects compatible LiDAR and IMU topics, runs the mapping pipeline locally, visualizes the trajectory and point-cloud map in the browser, and exports PLY and PCD files.
The main goal is to make it easier to inspect datasets, demonstrate LIO mapping, and generate maps without rebuilding a complete Linux and ROS environment.
The project is still early, and I am looking for users willing to test it with different sensors and datasets.
Demo: https://youtu.be/VGmrXOI95Uo?si=oqzMvNMH3C0D9Zje
I would especially appreciate feedback from anyone using Livox, Ouster, Velodyne, or Hesai data.

ROS Discourse General: AgileX NERO Robotic Arm Control with OpenClaw
1.Introduction
The recent popularity of OpenClaw has sparked a wave of enthusiasm for building personal robotic assistants. In this tutorial, we’ll demonstrate how to write an OpenClaw Skill that enables simple control of the AgileX NERO robotic arm.
Before proceeding, make sure you have already installed and configured the OpenClaw environment. Please refer to the official OpenClaw documentation for installation instructions.
2. Writing an OpenClaw Skill
Inside your OpenClaw agent workspace, create the following files under the skills directory:
.
├── config
│ └── hands_ctrl.yaml
├── scripts
│ └── hands_ctrl.py
└── SKILL.md
In this example, we are using the Three Provinces and Six Ministries multi-agent architecture, so the skill is placed inside the workspace of the Crown Prince agent, as shown below.
Don’t worry if you are not using this multi-agent architecture. The following implementation works equally well for a standard OpenClaw workspace.
2.1 SKILL.md
The contents of SKILL.md are shown below:
---
name: hands_ctrl
description: Use when the user wants OpenClaw to perform physical hand gestures like shaking hands or waving, or to recover/reset the hardware task. Executes the corresponding Python script based on user intent and securely interrupts any ongoing gesture before starting a new one.
---
# Gesture Control for OpenClaw
Use this skill when the user wants OpenClaw to act as a gesture controller for the hardware or robotic system.
## Inputs
Accept natural language commands or explicit action requests, such as:
- "握手", "shake hands", "let's shake"
- "挥手", "wave at me", "say hello"
- "恢复", "恢复任务", "recover", "reset"
Derive the intended action (`shake`, `wave`, or `recove`) from the user's input before execution.
## Interruption Handling (Ctrl + C)
Hardware can only perform one gesture safely at a time to prevent motor conflicts.
If the user requests a new gesture or a recovery command while a previous `hands_ctrl.py` process is still executing, you MUST interrupt the active process first. Send a `Ctrl + C` (SIGINT) to the running process to safely cancel the current hardware action before executing the new command. Ensure no orphaned background processes are left behind.
## Modes
### Handshake
Use when the user issues a handshake command.
Produce the following execution:
~~~bash
python3 skills/scripts/hands_ctrl.py --action shake
~~~
Implement this execution with:
- strict passing of the `--action shake` argument.
- capturing of standard output to confirm the hardware received the command.
### Wave
Use when the user issues a wave command.
Produce the following execution:
~~~bash
python3 skills/scripts/hands_ctrl.py --action wave
~~~
Implement this execution with:
- strict passing of the `--action wave` argument.
- capturing of standard output to confirm the hardware received the command.
### Recover
Use when the user issues a command to recover or reset the task.
Produce the following execution:
~~~bash
python3 skills/scripts/hands_ctrl.py --action recove
~~~
Implement this execution with:
- strict passing of the `--action recove` argument.
- capturing of standard output to confirm the hardware received the command.
## Backend Rules
Prefer executing the provided script over reimplementing the logic. Use `skills/scripts/hands_ctrl.py` as the sole backend interface for these gestures. Do not attempt to modify or rewrite the hardware control logic within the script unless explicitly asked to do so. Ensure process termination (SIGINT / Ctrl + C) is handled gracefully by the system.
## Packaging Rules
- The execution context must be at the root of the workspace so that the relative path `skills/scripts/hands_ctrl.py` is valid.
- Ensure the Python environment has the necessary dependencies installed to run the script.
## Workflow
1. Acquire and parse the user's intent from the prompt.
2. Analyze whether the intent maps to the Handshake, Wave, or Recover mode.
3. Check if there is an active `hands_ctrl.py` process currently running.
4. If a process is running, send a `Ctrl + C` (SIGINT) to terminate it and wait for it to stop completely.
5. Verify the existence of the `skills/scripts/hands_ctrl.py` file locally.
6. Execute the command corresponding to the matched mode.
7. Capture execution logs (`stdout` and `stderr`).
8. Update the user on the success or failure of the hardware action, clearly stating if a previous action was interrupted via Ctrl + C.
## Output Expectations
When reporting progress or final results, include:
- detected gesture intent (shake, wave, or recove)
- whether a previous process was interrupted via Ctrl + C
- the exact script command executed
- validation of execution (e.g., success message or error trace)
- open risks or hardware backend limitations
2.2 How the Skill Works
This Skill simply maps natural-language commands to different execution modes.
- When the user says “shake hands”, OpenClaw executes:
python3 skills/scripts/hands_ctrl.py --action shake
- When the user says “wave”, it executes:
python3 skills/scripts/hands_ctrl.py --action wave
- When the user requests “recover” or “reset”, it executes:
python3 skills/scripts/hands_ctrl.py --action recove
All three commands invoke the same backend script : hands_ctrl.py. The actual hardware control logic is implemented inside this Python script. The Skill itself is responsible only for invoking the script with the appropriate command-line argument.
2.3 hands_ctrl.py
The implementation of hands_ctrl.py is shown below.

exit(1)
main(args.action, pose_prepare, pose_left, pose_right)
3. Script Overview
This script controls the AgileX NERO robotic arm using predefined motion parameters stored in a YAML configuration file.
The YAML file defines each motion sequence using three joint-space poses:
- Preparation pose
- Left pose
- Right pose
When the program starts, it performs the following steps:
- Creates the robotic arm configuration and establishes the connection.
- Switches the robot into normal operating mode.
- Enables CAN communication.
- Enables the robotic arm.
- Sets the motion speed.
- Executes the requested action based on the command-line argument.
Three actions are currently supported:
- Wave
- Shake Hands
- Recover
For both the wave and shake actions, the robot first moves to a preparation pose and then continuously alternates between the left and right poses until the user interrupts the program with Ctrl+C.
When interrupted, the script automatically returns the robotic arm to its center (safe) position before exiting.
The recover action is a built-in recovery command that immediately moves the robotic arm back to its predefined safe position.
4.YAML Configuration
The motion parameters are stored in hands_ctrl.yaml.
actions:
wave:
pose_prepare: [0.8, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]
pose_left: [0.8, 0.0, 0.0, 0.6, -0.6, 0.0, 0.0]
pose_right: [0.8, 0.0, 0.0, -0.6, -0.6, 0.0, 0.0]
shake:
pose_prepare: [0.0, 0.6, 0.0, 1.0, 1.57, 0.0, 0.0]
pose_left: [0.0, 0.6, 0.0, 1.0, 1.57, 0.0, 0.0]
pose_right: [0.0, 0.6, 0.0, 0.6, 1.57, 0.0, 0.0]
Each action consists of three joint-space poses:
- pose_prepare – The initial pose before starting the motion.
- pose_left – The first motion pose.
- pose_right – The second motion pose.
The Python script loads these poses at runtime and executes the corresponding motion sequence according to the selected action.
5.Demo
After completing the configuration above, you can control your OpenClaw-powered robotic assistant using natural language and command the AgileX NERO robotic arm to perform simple gestures such as waving, shaking hands, and recovering to a safe position.
The demonstration is shown below.

FAQ
Q1:Can OpenClaw Control Real Robots?
Yes. OpenClaw is responsible for task understanding and Skill execution. Through Skills, it can connect to external programs and hardware devices, enabling control of real robots.
Q2:What Is an OpenClaw Skill?
An OpenClaw Skill is a modular extension that expands the capabilities of an AI Agent. Developers can define trigger conditions and execution logic in a SKILL.md file, allowing the Agent to invoke the appropriate scripts based on natural language instructions.
Q3: How Do You Use OpenClaw to Control the NERO 7-DoF Robotic Arm?
The control workflow includes the following steps:
- Install and configure the OpenClaw environment.
- Create a robot control Skill.

ROS Discourse General: Ros2_info — a terminal workspace lens for ROS 2 (TUI + optional local AI)
Hi all,
Sharing a tool I’ve been building: ros2_info — a fastfetch-style ROS 2 workstation dashboard with a full-screen terminal UI. Written in Rust, so it runs headless over SSH and on Pi/Jetson-class hardware without any Electron/webview overhead.
It’s not trying to replace your editor or your terminal — it’s trying to replace the five terminals you already have open during bring-up and debugging:
- Live dashboards — nodes, topics, services, actions, workspace + build status, DDS/domain/sourcing state, all on one screen instead of five.
- Integrated PTY terminal —
ros2,colcon build,ros2 launchrun live alongside everything else, not in a separate window. - Multi-tab editor with Neovim keybindings, for when you need to touch a file without leaving the session.
- Local AI assistant (Ollama, fully offline, opt-in) —
ai scan/ai fix/ai explainfor build errors. Every suggested change is diff-gated before anything is applied, and the tool works exactly the same with this switched off entirely.
Build-error triage — ai scan / ai fix / ai explain, diff-gated so nothing is applied without review - In-TUI chat assistant, plus a standalone AI web chat if you’d rather work outside the terminal
- Autonomous coding mode — give it a goal, it iterates on the code toward that goal inside the same sandbox + diff-gate rails as everything else (this writes/edits code autonomously, it doesn’t drive the robot at runtime)
- so i prefer you small model like vibethinker 3b or gemma E2B, E4B
- ROS 2 graph canvas, git/
ghintegration, and a namespaced sandbox mode (/sandbox) for experimenting without touching the real graph. - In-process plugin API for extending it further.
Honest pitch: you can do all of this with the raw CLI plus your editor of choice — I’m not claiming to be smarter than either. It’s just that during active bring-up and debugging, having graph state, build output, and a terminal in one screen is faster than context-switching across five.
Single static binary, MIT licensed, supports Humble/Jazzy/Iron/Rolling. Feedback and PRs welcome — happy to answer questions.

ROS Discourse General: LinkForge: Exploring an Intermediate Representation (IR) for Robot Descriptions
Hi everyone,
LinkForge recently passed 5,000 downloads on the Blender Extensions platform, which encouraged me to share a broader idea behind the project rather than just another release announcement.
Over the past year, I’ve been working on LinkForge, which started as a Blender extension for creating robot models. As the project evolved, I realized the more interesting problem wasn’t Blender itself, it was the way we author robot descriptions.
Today, formats like URDF and XACRO often become the project’s source of truth. While they work well as interchange formats, I’ve started to think they behave more like compiled artifacts than true source representations.
That led me to build LinkForge around a programmable Intermediate Representation (IR) that can:
- compose robot models programmatically,
- validate kinematics and physical properties before export,
- and compile to formats such as URDF and XACRO.
The long-term goal isn’t to replace URDF or ROS. Quite the opposite, it’s to provide a tool-agnostic authoring and validation layer that sits before existing ROS workflows.
I’m interested in hearing from the ROS community:
- Do you think robot description workflows are missing an intermediate representation?
- Have you encountered limitations using URDF/XACRO as the primary authoring format?
- How do larger teams currently manage robot descriptions while preserving design intent?
I’d genuinely appreciate feedback, especially from people maintaining complex robots or working on large simulation pipelines.

ROS Discourse General: RoboShield: A Low-Latency Out-of-Band RTPS Watchdog in Rust
Hey everyone! ![]()
I’ve been working on something I’m pretty excited about and wanted to share it with the community.
RoboShield is a real-time RTPS security watchdog I wrote in Rust. It basically sits on the wire (like on a NanoPi R2S with dual ethernet) and sniffs DDS/RTPS packets to catch stuff like rogue nodes joining your network, someone flooding /cmd_vel, or unauthorized publishers trying to hijack topics.
GitHub: GitHub - Amin-Ahmed-G/robotshield · GitHub
What it does
- Parses raw RTPS submessages (DATA, HEARTBEAT, ACKNACK, etc.) from UDP captures using
libpcap - Checks every packet’s GUID prefix against a TOML-based whitelist
- Tracks per-topic message rates with a sliding window to catch flood attacks
- Logs alerts as structured JSON (for SIEM tools or just grepping through logs)
Why not just use SROS2?
SROS2 is great, but setting up PKI certificates for every node on a fleet of robots is painful, and the crypto overhead can mess with tight real-time loops. RoboShield works out-of-band — plug it between your robot and the network, zero changes to your existing nodes.
Performance
I ran some benchmarks and got ~1.36 μs average processing time per packet (parse + policy check on an x86 dev machine) in release mode, which is way under what you’d need for even 1kHz control loops. NanoPi R2S hardware benchmarks are planned next.
I’m a 4th year Robotics & Automation student and this started as a security research project targeting ICRA/IEEE RAS. Would love to hear any feedback, especially from folks who’ve dealt with DDS security in production!
Feel free to connect with me on LinkedIn as well!
Cheers,
Amin ![]()
