ROS Discourse General: Tuning StereoSGBM on PS5 Camera (ROS 2 Galactic) for Dense Depth Maps
Hi everyone, I’m working on setting up a stereo camera PS5 HD Camera in ROS 2 Galactic for stereo depth estimation using stereo_image_proc ( DisparityNode ), with the end goal of feeding the depth data into RTAB-Map for 3D reconstruction. I transitioned from StereoBM to StereoSGBM ( stereo_algorithm: 1 ) to handle the wide-angle camera setup better, but I’m having trouble finding the optimal combination of parameters which result in a dense point cloud with smooth surfaces. My depth output keeps

ROS Discourse General: RobotCAD v12.10.0 is released!
It’s been a long time since I posted any news. Many new features and fixes have been released. Here is a list of some of them that have appeared in recent versions. Added RobotCAD MCP server for agentic robot assembling. Updated Models Library. More models (219 now) and faster import . Added xacro and mjcf models import from Models Library. Added sensors field of view with reacting to sensor parameters. Other features and fixes: Fixed an error in collision creation for objects obtained via a lin

ROS Discourse General: Has anyone found a reliable way to validate a hand eye calibration result?
I have been trying to work out how a hand eye calibration should be validated and I have not found any complete answer yet There are some tools I looked at (MoveIt Calibration, easy_handeye, Kalibr) that just print reprojection error or transform, but I could not find a clear way to decide from that whether the result can be trusted or not. I read some of their GitHub issues and many people seem to end up in the same place “result looks off” and the only way to find out why is to ask someone mor

ROS Discourse General: ROS2 Parameter Value Querying
I need a much better way of grabbing the current value of every parameter of every node running on my system. Not just the dynamic ones, but the defaults and overrides from the launch system. From an experiment documentation standpoint, this is extremely important to understanding exactly how things are configured when producing data and later if data is changing figuring if one of these changed. Sure some nodes may be less important and their parameters not matter much, but there would remain m

ROS Discourse General: MoveIt 2 Setup Assistant Tutorial: Custom 3-Joint Arm Troubleshooting Guide (ROS 2 Jazzy)
Hello ROS Community, I want to share a comprehensive step-by-step video tutorial on configuring MoveIt 2 from scratch for a custom robotic manipulator on ROS 2 Jazzy and Ubuntu 24.04 . While most official tutorials use high-DOF industrial manipulators (like the Franka Emika Panda), building configurations for smaller or custom arms often introduces unique glitches that standard guides donâ€™t cover ( 0:33 ). In this video, I take a 3-joint printed arm model ( arduinobot ) with a gripper ( 0:17 )

ROS Discourse General: Introducing NoDL: the Node Definition Language (ROSCon recap)
TLDR: come work on NoDL in the rosgraph-wg . Join the mailing list for automatic calendar invites to meetings: https://groups.google.com/u/1/g/rosgraph-wg Hi everyone! @emersonknapp and I presented “The Legible Node” at ROSCon last week. We talked about two things: Thin nodes - your node is an interface adapter, it should not contain robot logic NoDL - the node definition language that allows you to statically declare your node interfaces If you didnt catch it, here are the slides (the_legible_n

ROS Discourse General: Question on local vs. remote inference placement for perception tasks
Hey all! ECE undergrad here, exploring an inference-routing idea for robots (deciding at runtime whether a perception or higher-level AI task runs onboard, on a nearby edge server, or in the cloud, based on deadlines, network conditions, and local compute load) and trying to validate the problem before building anything. For those running real robots: is your local/remote split for perception or AI tasks fixed, or does it ever change dynamically? Has latency or local compute contention ever actu

ROS Discourse General: Ros2_unbag is now available via the ROS 2 buildfarm 📦
Hi everyone, A small-but-important update for ros2_unbag Starting with v1.3.0 , ros2_unbag is now released through the official ROS 2 buildfarm. That means installation is now as simple as: sudo apt install ros-<distro>-unbag and then: ros2 unbag No separate pip install, no cloning, no building from source — just a regular ROS package. For anyone who hasn’t come across ros2_unbag yet: Your robot packs the bags; ros2_unbag brings them to your room, unpacks them, and sorts out the mess. No lost lu

ROS Discourse General: Fifteen Years of MoveIt, and the Next Fifteen
Today we announced that PickNik Inc. and Qualcomm Technologies, Inc. are joining forces . Before I go into that, I want to talk about MoveIt, because MoveIt is the reason any of this happened. If you have learned about robotic arm manipulation in the past decade and a half, or been involved in manipulation R&D, there’s a good chance you’ve used MoveIt. More than 560 people have contributed code across the MoveIt project, which today spans 40 repositories, 6,700 GitHub stars, and 4,400 forks. The

ROS Discourse General: From CT Scan to Robotic Surgery Prototype: Kidney Stone Detection & PCNL Planning in ROS 2
Hi all, I’d like to share a research prototype that connects medical CT imaging to ROS 2 visualization and robot simulation . The pipeline starts from a DICOM / NIfTI CT scan, segments kidneys and nearby organs, finds stone candidates, builds 3D meshes, ranks PCNL (percutaneous nephrolithotomy) access corridors, then visualizes the anatomy in RViz and Gazebo . A Franka FR3 with a surgical needle can replay the selected path in simulation. This is not a clinical tool and not medical advice. It is

Hi everyone! Here’s from the D-Robotics team. We’re excited to share that our team will be at ROSCon Global 2026 in Toronto, September 22–24 . We’re looking forward to meeting fellow ROS developers and robotics folks in person. For D-Robotics , ROS 2 is not an add-on — it is a core part of the RDK robotics development experience. Across the RDK platform, we support multiple ROS 2 distributions, while TogetheROS.Bot builds on ROS 2 with hardware-accelerated capabilities tailored for robotics. If

ROS Discourse General: Native ROS 2 on Zephyr with Cyclone DDS
Hi, I have been experimenting with native DDS for ROS 2 on Zephyr and recently got the standard ROS 2 C client stack running on an ESP32-S3 over Wi-Fi. The current stack is: rclc -> rcl -> rmw_cyclonedds_c -> Cyclone DDS -> Zephyr The board joins the DDS/RTPS network directly, without a Micro XRCE-DDS Agent. The work is split into two repositories: ros2_zephyr for the Zephyr integration and static ROS 2 build rmw_cyclonedds_c for the C RMW implementation and generated Cyclone DDS type support I

ROS Discourse General: Ros2-apt-source bumped to v 1.3.0
I’ve just noticed the ros2-apt-source package has been bumped to v1.3.0. Nothing special was added, just Fedora support. If you have v1.2.0 hardcoded to your deploy scripts, it’s time to switch to 1.3.0 (for those who have already this package installed, it will auto-update, so no worries there). 1 post - 1 participant Read full topic

ROS Discourse General: Has anyone written a custom I²C transport for micro-ROS (or any MCU ROS stack)?
Small embedded team at a startup, weighing an idea before we commit to it. As far as I can tell, none of the MCU ROS stacks support I²C out of the box — micro-ROS does UART/UDP/CAN-FD, zenoh-pico does serial/UDP/TCP, Cyphal does CAN/serial. I²C isn’t on any of those lists. So if we want a board to be a ROS node talking over I²C, it looks like we’d have to write that transport layer ourselves. micro-ROS at least exposes a custom-transport API (the open/close/write/read hooks + set_custom_transpor

ROS Discourse General: Open Source Safety Consortium: sharing safety evidence, not just code
I’d like the next autonomy team to spend less time reconstructing basic safety analysis, and more time finding what was missed. That’s why I helped start the Open Source Safety Consortium ( opensourcesafe.com ), with Polymath Robotics as a founding member. We’re developing reusable evidence for open-source components: hazard analyses, safety requirements, tests, assumptions, and known gaps, versioned alongside the code. Our first worked example is an open-source protective-stop prototype, with f
