- 02AffectGuard-HRI: emotion-aware robot behavior with a non-overridable safety envelope (ROS 2 Jazzy, pet-project)Hi all, I’ve been building AffectGuard-HRI , a pet-project framework on ROS 2 Jazzy for social/home robots that adapt their behavior to a person’s detected emotional state — while keeping a hard safety envelope between “what the robot perceives” and “what it’s actually allowed to do.” Repo: GitHub - oleg-vdv/affectguard-hri · GitHub The idea was to build three things together , not in isolation: Multi-modal affect perception — separate video (FER+ ONNX) and audio (MFCC + ONNX) emotion nodes, fusoleg-vdv
- 03Best practices op gebied standaardisatie en open (source) softwareHallo allemaal, Ik werk als associate lector Cognition & AI for Robotics bij het lectoraat SMART Mechatronics & Robotics van Saxion. Wij zijn initiatiefnemer van het lectorenplatform Applied Robotics & AI waar we met alle robotica-onderzoeksgroepen van hogescholen in Nederland willn samenwerken. Binnen dat platform kwam naar voren dat standaardisatie en goed gebruik van open source software een onderwerp is waar ze graag verder willen ontwikkelen. Het plan is daarom om een project op te zetten wWilco
- 04Does anyone else struggle to get accurate inertia and mass values for 3D-printed parts in sim?I was playing around with a LeRobot SO101 arm and simulating it in [MuJoCo/PyBullet/Gazebo]. Something that kept bugging me: CAD tools, URDF exporters, (and slicers’ STEP exports) compute the inertia tensor as if the part is a solid block of plastic which is not accurate at all. When you feed that solid-block inertia into a simulator, the dynamics are off, which as per my understanding widens the sim-to-real gap. I tried finding a tool for this but did not find anything. So I vibe coded a small lakshya_saraf
- 05Adaptation needs in robotic systemsHi 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 neeMehran
- 06Midwest United States ROS2 mirrorHello all, I am here on behalf of Nulled, a small independent hosting company based out of the Midwest United States. Someone in our community requested that we host the ROS2 repo on our public mirror, https://mirror.nulled.llc . We saw no reason not to and so we have. The mirror syncs twice a day, once at 05:00 America/Chicago and once at 17:40 America/Chicago. It is available over HTTP and HTTPS at /ros2/ubuntu/. Our infrastructure support and notification inbox is infra@nulled.llc. We would amori

While learned VLA policies using GR00T N1.7 provide incredible flexibility in perception and language understanding, real-world robot operations require robust safety checks, exception handling, and deterministic rule-based controPyo
- 08Showcase: Beam AgroBot V2 – Autonomous Agricultural Robot Built with ROS 2, Nav2, MoveIt 2 and RealSenseHello everyone, I’d like to share Beam AgroBot V2 , an autonomous agricultural robot that I’ve been developing over the past several months as a personal robotics project. My name is Hatim Ahmed Hassan , a Mechanical Engineering graduate with a strong interest in robotics, autonomous systems, and embedded development. The primary objective of this project has been to gain a deep understanding of how the different components of a modern robotic system work together—from mechanical design and roboxaatim
- 09ROS 2 node for PlayStation 5 HD cameraHi community. I have implemented a simple ROS 2 node for the official PlayStation 5 HD camera ( https://www.playstation.com/en-us/accessories/hd-camera/ ) to get it work with my own camera. It makes the setup of the camera easier. About camera. PS 5 camera is a good HD stereo camera (two monocular cameras) with high resolution (1080p Capture, frame rates of up to 60 FPS). That can be a good choice for stereo visual SLAM. Moreover it’s quite cheap option (60 USD). I think it could be a good idea Vladimir_Privalov
- 10Announcing ros-env: Access ROS 2 messages from Rust with just CargoHey 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 needmaspe36
- 11Real-time robot dashboards in React without a separate visualization serverIf 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, witJaya_Sai_Kishan

I’m not sharing technical details publicly at this stage, but the problem is real, the approach is novel, and I’m working toward IP protection. Looking for a technical co-founder with hardware and sensing experience — equity-motivated, entrepreneurially inclined, IP-unencumbered. Fresh PhD grads and people between roles are ideal.

- 21Xbox controller teleop for TurtleBot3, with a brake and haptic feedback (sim + real robot)A small ROS 2 Jazzy package for driving a TurtleBot3 with a Bluetooth Xbox controller with added haptics feedback. Left stick drives, right stick turns, both capped at the real Burger limits (0.22 m/s, 2.84 rad/s). LT or RT acts as a brake. Haptic feedback through the controller’s rumble: it scales with speed, plus an optional lidar proximity warning that ramps up as you drive toward an obstacle. The haptics use the joy package’s /joy/set_feedback , so no custom driver is needed. The laptop sideprakash-aryan
- 22urdf_validator v1.0 — physics-aware URDF validation (open source)Every ROS 2 developer who’s written a URDF has hit this: check_urdf passes your file, you launch Gazebo, and the robot collapses or explodes anyway. That’s because check_urdf is syntax-only — it cannot tell you whether your inertia tensors, mass values, or joint effort limits are physically plausible. A 2024 empirical study of 221 ROS bugs (ROBUST, Empirical Software Engineering ) found that URDF semantic errors like this — bad mass, inertia, kinematic specs — are among the most common real-worlNotlord69

- 27Offboard 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 ) Cesar_Flores

There still hasn’t been one since switching to Ubuntu Resolute as the Tier 1 platform and the missing packages cause failures on some of my CI’s. Could you guys consider making a new sync? @mjcarroll @cottsay I’m not sure who the “ROS Boss” is for the Rolling distribution, I would appreciate pointing to the right person. 2 posts - 2 participants Read full topicBlazej_Sowa
- 30Pyspacemouse axis conventionsThanks 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 - PySpacPeterMitrano
