ROS Discourse General: Adaptation needs in robotic systems
Hi robotic developers, Are you working with Behavior Trees, robotics, ROS/ROS 2, autonomous systems, or robot decision-making ? We are conducting a research study on adaptation needs in robotic systems that use Behavior Trees. If you work with robotic systems, we’d greatly appreciate your input. We’re conducting a short survey to answer two key questions: The relevance of different adaptation needs in robotic systems. The suitability of different BT adaptation approaches for addressing those nee

ROS Discourse General: Announcing ros-env: Access ROS 2 messages from Rust with just Cargo
Hey all! I’m one of the maintainers of ros2_rust , and we recently released a new crate, ros-env , that aims to unify ROS 2 message consumption in Rust. If you’re already generating Rust code for your message interfaces with rosidl_generator_rs , you can add ros-env as a regular Cargo dependency and access the message types from any packages in your sourced ROS 2 environment. // Assuming the Rust crate for `shape_msgs` is in `AMENT_PREFIX_PATH` use ros_env::shape_msgs::msg::Plane; You don’t need

ROS Discourse General: Real-time robot dashboards in React without a separate visualization server
If you’ve built an operator UI or ground station in React, you’ve probably hit the same wall I did: the moment you need real-time telemetry visualization, your options are to run Foxglove or Grafana as separate infrastructure and iframe them in, or hand-roll canvas components from scratch. Neither is great when what you actually want is telemetry views that live natively inside the app you’re already building. So I built Altara: a set of MIT-licensed React components for real-time telemetry, wit

ROS Industrial: ros2_canopen: Natively Integrating CANopen Devices into the ROS 2 Ecosystem
CANopen has long been one of the most widely used communication standards in industrial automation. Built on top of the CAN bus and standardised by CAN in Automation (CiA), it connects motor drives, I/O modules, sensors and other field devices across machines, robots and vehicles. The ros2_canopen stack, maintained under the ROS-Industrial umbrella, brings this ecosystem natively into ROS 2. It lets developers describe a CAN bus, bring up a CANopen master, and talk to every device on the bus thr

ROS Discourse General: Offboard Control with PX4 & ROS 2 (Micro XRCE-DDS)
I wanted to share an architectural pattern for handling autonomous drone navigation using ROS 2 (Jazzy) and PX4 Autopilot via Micro XRCE-DDS, specifically regarding the Offboard mode failsafe. The Problem: When developing an autonomous flight node in C++, transitioning to PX4’s Offboard mode can be tricky. PX4 implements a strict failsafe: it will reject any VEHICLE_CMD_DO_SET_MODE to Offboard unless it detects a continuous stream of setpoints (e.g., TrajectorySetpoint and OffboardControlMode )

ROS Discourse General: Pyspacemouse axis conventions
Thanks to new contributor, we have documentation of, and several options for, axis conventions in pyspacemouse not yet released to pypi, but please try it out (you can pip install directly from github!) and let me know what you think. Longer term, the plan is to change the default convention to HID , because the LEGACY convention is, frankly, insane, and I don’t want all users to have to “fix it” on their own. spacemouse.kubaandrysek.cz Axis Conventions - API documentation for this tool - PySpac

ROS Discourse General: Guidelines for AI-Assisted Contributions in the ROS Project
Hello fellow ROS users, maintainers, contributors and anyone else who may be passing by. Due to a recent uptick in LLM-authored pull requests, the ROS PMC has elected to extend the upstream OSRF policy on the use of generative tools to help provide some boundaries/guidelines on the use of these tools. These tools and technologies are constantly changing, so this isn’t intended to serve as a permanent policy, but rather it is to provide a framework for how to interact on ROS-related projects. The

ROS Discourse General: A Standard Interface from LLM to Robot Actions
Hi ROS community, I’m working on ClawsJoy Robotics, a proposal for a standard interface between LLM-based cognitive systems and ROS/2 robots. The core idea: any LLM outputs an action, any robot implements these standard topics. The Problem Every robotics company maps “pick up the cup” to different ROS/2 interfaces: Company A: custom service /manipulation/pick Company B: action server /grasp_object Company C: proprietary SDK There’s no standard way for an LLM agent to tell a robot what to do. The

ROS Discourse General: Cad to urdf conversion
If you’re a robotics engineer, you’ve probably lost hours to URDF generation. Not because the robot is complex but because the tooling is. Renaming mates. Fixing joint axes. Recreating reference frames. Starting over because the CAD came from the “wrong” software. I got tired of that workflow, so I built Jointly. Upload a STEP assembly then get a draft URDF with inferred joints, inertia, collision meshes, and a live 3D preview. It’s not magic , you’ll still review the result. But it turns hours

ROS Discourse General: Ros2-dev-suite, a StudioCode extension
As shared in a lightning talk at ROSConFr: I have finally completed and “clauded” a comprehensive VS Code extension for ROS 2 development: a unified explorer, live parameter tuner, service/topic/action caller, log viewer, and syntax highlighting for interface files. My favorite features of the extension, among others: Dynamically changing node ROS parameters at runtime via a YAML panel and comparing live params vs. edits: very handy for tuning PIDs, covariances, etc. Possibility to edit an exist

ROS Discourse General: Sony AI's Ace (Nature cover, beat a pro table tennis player) — running on ROS 2
Can you believe this is running ROS 2? Sony’s Ace Robot Beats Top Table Tennis Pros in Real Matches Sony AI’s Ace just landed on the cover of Nature — the first robot ever to beat a professional table tennis player. Let that sink in for a second: • It tracks a ball moving at 20 m/s with spin over 9,000 rpm • Perceives it in 10.2 ms (event-based vision) • Decides and swings on a 1 kHz control loop • And returns the ball at up to 19.6 m/s This is physical AI right at the edge of what’s possible —

ROS Discourse General: Rclnodejs 2.1: Native ESM for a Web-Native ROS 2 SDK
Hi all, rclnodejs 2.1.0 is out — and it’s a step toward making rclnodejs a web-native SDK for ROS 2 : a platform for bringing ROS 2 to the browser and the modern JavaScript ecosystem. With 2.1.0, the whole package is now native ESM , so building web dashboards, teleop UIs, and browser bridges on ROS 2 feels native to today’s web tooling — with the full ROS 2 runtime still underneath whenever you need real nodes. TL;DR — 2.1.0 makes rclnodejs native ESM end-to-end. import rclnodejs from 'rclnodej

ROS Discourse General: Anomaly Detection. Beta testers wanted
Hi, I used to work at a robotics startup that built robotic dishwashers. ( https://armstrong.ai/ ) And part of my job was to set up diagnostics, monitoring and alerting. Aside from not being the most interesting part of my job, it was just plain tedious to manually set (and continually tune) thresholds for various signals, topics, etc. I frequently thought it would be nice to have a system that would automate that part of my job and now that the company has closed, I built it. Now I have reached

ROS Discourse General: Embeddable React telemetry components — a browser ground station for MAVROS
I maintain Altara, a set of MIT-licensed React components for real-time robotics telemetry (PFD, moving map, gauges, event log), and I wrote up building a small drone ground station with them that talks to MAVROS over rosbridge. The thing I was trying to solve: I wanted a status dashboard our team could open in a browser tab and drop into our own app, rather than running a separate native GCS. So the components are embeddable and themeable rather than a standalone tool. Writeup (the rosbridge/MA

ROS Discourse General: KRS Unleashed: Easier Hardware Acceleration Prototyping on FPGA
Hey All, I want to present KRS Unleashed , the tool I am now developing/refactoring/extending since 1 year as part of my PhD. Some of you might still know KRS (short for Kria Robotic Stack as originally developed by Xilinx/AMD for their Kria platform) as the toolchain developed until 2023 by the ROS 2 Hardware Acceleration Working Group · GitHub . (Short Summary for those who don’t) It was a proof-of-concept framework that allowed to synthesize bitstreams, create a sysroot and cross-compile appl

ROS Discourse General: Minimum CMake version to support Humble at this time
REP 2000 specifies MacOS support for CMake 3.14.4 in Humble: This is the lowest number for the whole Humble release. However, MacOS has this note: " ** " means that the dependency may see multiple version changes, because the dependency uses a package manager that continually updates the dependency without a stable API. I don’t work with MacOS myself, so I don’t know how it behaves. Is it still needed nowadays to support 3.14.4 to get full support for Humble on MacOS, or can I just ignore this a

ROS Discourse General: Dual-Arm Nero Reinforcement Learning in Isaac Lab: Reach Task Training Example
Robotic manipulation remains one of the most important research directions in embodied AI. While traditional kinematics-based controllers provide stable motion execution, they often struggle in unstructured environments where adaptability is required. Recent advances in Reinforcement Learning (RL) have enabled robotic arms to learn task-oriented behaviors directly from interaction, making it possible to achieve robust control policies without manually designing every motion strategy. In this pro
