Announcing MoveIt Pro 9 with ROS 2 Jazzy Support

Hi ROS Community!

It’s been a while, but we’re excited to announce MoveIt Pro 9.0, the latest major release of PickNik’s manipulation developer platform built on ROS 2. MoveIt Pro includes comprehensive support for AI model training & execution, Behavior Trees, MuJoCo simulation, and all the classic capabilities you expect like motion planning, collision avoidance, inverse kinematics, and real-time control.

This release adds support for ROS 2 Jazzy LTS (while still supporting ROS Humble), along with significant improvements to teleoperation, motion planning, developer tooling, and robot application workflows. MoveIt Pro now includes new joint-space and Cartesian-space motion planners that outperform previous implementations, to improve cycle time, robustness, and industry-required reliability. See the full benchmarking comparison for details

MoveIt Pro is developed by the team behind MoveIt 2, and our goal is to make it easier for robotics teams to build and deploy real-world manipulation systems using ROS. Many organizations in manufacturing, aerospace, logistics, agriculture, industrial cleaning, and research use MoveIt Pro to accelerate development without needing to build large amounts of infrastructure from scratch.

What’s new

Improved real-time control and teleoperation with Joint Jog

MoveIt Pro now includes a new “Joint Jog” teleoperation mode for controlling robots directly from the web UI. This replaces the previous MoveIt Servo based teleoperation implementation and introduces continuous collision checking, configurable safety factors, and optional link padding for safer manual control during debugging or demonstrations.

Scan-and-plan workflows

New scan-and-plan capabilities allow robots to scan surfaces with a sensor and automatically generate tool paths for tasks like spraying, sanding, washing, or grinding. These workflows make it easier to build surface-processing applications.

New Python APIs for MoveIt Pro Core

New low-level Python APIs expose the core planners, solvers, and controllers directly, enabling developers to build custom applications outside of the Behavior Tree framework. These APIs provide fine-grained control over motion planning and kinematics, including advanced features like customizable nullspace optimization and path constraints.

Improved motion planning APIs

Several updates improve flexibility for motion generation, including: improved path inverse kinematics, orientation tracking as a nullspace cost, customizable nullspace behavior, tunable path deviation tolerances.

Developer productivity improvements

The MoveIt Pro UI and Behavior Tree tooling received a number of improvements to make debugging and application development faster, including a redesigned UI layout and improved editing workflows, Behavior Tree editor improvements such as search and node snapping, better debugging tools including TF visualization and alert history

Expanded Library of Reusable Manipulation Skills

MoveIt Pro also includes a large library of reusable robot capabilities implemented as thread-safe Behavior Tree nodes, allowing developers to compose complex manipulation applications from modular building blocks instead of writing large amounts of robotics infrastructure from scratch. See our Behaviors Hub to explore the 200+ available Behaviors.

[Policy Change] Detailed Standards for REP-2026-04 (Lyrical Enforcement)

Hi everyone,

Following up on the recent announcement regarding the Lyrical Luth release requirements, the PMC has finalized the automated enforcement protocols. To ensure our May release remains on schedule, we are providing expanded guidelines and examples for the new rhyme-lint and README.shanty checks.

Effective immediately, all pull requests targeting the rolling or lyrical branches must pass these poetic audits.

1. The rhyme-lint Mandatory CI Check

All pull requests will now trigger a rhyme-lint action. If your commit message lacks proper meter or rhyme, the build will fail with a 403: UNPOETIC_CONTRIBUTION error.

Accepted Commit Styles:

  • The Heroic Couplet (for Security/Bug Fixes):
fix: A buffer overflow was found in C,
We've locked the heap to keep the memory free.
  • Iambic Pentameter (for Feature Additions):
feat: The twenty-standard now we must embrace,
To bring C++20 speed to every space.
  • The Middleware Haiku (for RMW Updates):
Packets drift like leaves,
The middleware finds the path,
Silence in the logs.

2. The README.shanty Documentation Standard

Any new package added to the core must include a README.shanty file. This ensures our documentation can be easily memorized and sung during long deployment cycles or deep-sea robotics missions.

  • Note: Harmonies are optional but encouraged for Tier-1 platforms.

Example: README.shanty for rcl::Buffer

(To the tune of “The Wellerman”)

There once was a node that sent a frame,
Without a copy or a name,
The CPU was much to blame,
For latency so high! (HUH!)

Soon may the Zero-Copy come,
To bring us throughput, megabytes, and fun,
When the data transfer’s done,
We’ll take our leave and go!
We used the vendor’s memory backend,
A pointer sent to every friend,
The bandwidth limit met its end,
Beneath the Lyrical sky!


3. The Lyrical Luth Rhyming Dictionary

We recognize that many maintainers may find this transition challenging. To assist, the PMC has curated an initial dictionary of “Technical Rhymes” to help you pass CI.

ROS Term Approved Rhymes Example
Node Code, Mode, Load, Road “A lonely node / with heavy load.”
DDS Success, Progress, Finesse “Tune the DDS / with pure finesse.”
Topic Myopic, Tropic, Microscopic “A hidden topic / so microscopic.”
RMW Now, How, Allow, Brow “The RMW / we fix it now.”
Linter Splinter, Winter, Printer “The static linter / cold as winter.”
Pointer Anointer, Appointer “The null pointer / a soul-disappointer.”
Humble Rumble, Stumble, Grumble “Backported from Humble / without a stumble.”

Compliance and “ROS-ffice Hours”

We understand this is a significant shift in our development workflow, but we believe it is necessary to harmonize our ecosystem. To help with the transition, our upcoming “ROS-ffice Hours” sessions will be dedicated to bardic troubleshooting.

Let’s make this May the most harmonious release in robotics history.

Custom Capabilities in Transitive Robotics | Cloud Robotics WG Meeting 2026-04-13

Please come and join us for this coming meeting at Mon, Apr 13, 2026 4:00 PM UTCMon, Apr 13, 2026 5:00 PM UTC, where we plan to continue our Transitive Robotics tryout by trying one of the more advanced features: writing and deploying a custom capability. This feature allows customers to write their own custom code and deploy it to their robots alongside the features available directly from Transitive Robotics.

Last session, we tried running Transitive Robotics on a Turtlebot. We managed to remotely operate the robot, plus set up Maps as a capability which unfortunately didn’t work due to incompatibility with ROS 2 Jazzy (support has since been added for Jazzy). If you’re interested to watch the meeting, it is available on YouTube.

The meeting link for next meeting is here, and you can sign up to our calendar or our Google Group for meeting notifications or keep an eye on the Cloud Robotics Hub.

Hopefully we will see you there!

ROS2 Launch File Validation

Introducing an XML launch file scheme

XSD schema for validating ROS2 XML launch files.
Catch syntax errors before runtime and get IDE support.

Why

For the package.xml we have had it for years, a scheme.

But we found my muscle memory often typing type= instead of exec=.
Or $(find my_pkg) instead of $(find-pkg-share my_pkg).

And we could unit-test the node all we wanted, these errors only popped up in integration tests or even on the robot itself.
Would it not be nice if your editor already warned about you it?

How

Embed in launch file

Start your launchfile like this:

<?xml version="1.0"?>
<?xml-model href="https://nobleo.github.io/ros2_launch_validation/ros2_launch.xsd" schematypens="http://www.w3.org/2001/XMLSchema"?>

<launch>

Command-line validation

Quickstart! Validate all your launch xml files in your workspace right now!

xmllint --noout --schema <(curl -s https://nobleo.github.io/ros2_launch_validation/ros2_launch.xsd) **/*.launch.xml

This was verified internally and on some larger public repositories like autoware. Even found an issue :slight_smile:

RFC: Open standard for robot-to-human light signaling — looking for technical feedback from ROS 2 developers

Hi everyone,

I’m working on an open standard called LSEP (Luminae Signal Expression Protocol) — a state machine specification for how robots communicate intent, awareness, and safety states to humans through light signals.

The problem it solves:

Most robotic platforms implement ad-hoc LED patterns with no shared semantics. Robot A blinks blue for “idle,” Robot B blinks blue for “navigating.” There’s no interoperability, and no way for a human in a shared workspace to learn one signal language that transfers across platforms.

LSEP defines a modular 9-state architecture: 6 Core states (IDLE, AWARENESS, INTENT, CARE, CRITICAL, THREAT) and 3 Extended states (MED_CONF, LOW_CONF, INTEGRITY) with deterministic mappings from sensor inputs like Time-to-Collision (TTC) to signal outputs. The full spec is open: https://lsep.org

Where ROS 2 comes in:

We’ve designed LSEP to run as an isolated safety node — it reads from your perception pipeline (TTC, proximity, sensor health) and publishes signal commands. It doesn’t touch your navigation stack. The architecture pattern uses lifecycle nodes to keep the signaling guardrail separate from autonomy logic.

What I’m looking for:

We’re running a free Beta program for 20 ROS 2 developers who want to stress-test the integration. No cost — your payment is brutal, unfiltered technical feedback and (optionally) a short write-up on how it fits into your stack.

The program covers:

- Translating TTC and proximity data to deterministic state machine outputs

- EU AI Act compliance layers (Art. 9 & 50) for high-risk physical AI transparency

- LSEP core & extended states: mechanics of the 9-state multimodal standard

- ROS 2 integration: isolating the LSEP safety node from your navigation stack

- Sensor fusion resilience: hysteresis and fallback patterns for sensor dropouts

Not looking for:

This isn’t a pitch. I’m not selling anything here. I’m looking for the people who actually build these systems to tell me where LSEP breaks, what’s missing, and what’s naive. The harshest feedback is the most useful.

Full spec: https://lsep.org

Beta registration: https://www.experiencedesigninstitute.ch

PLCnext ROS Bridge: Enabling Hardware Interoperability Between Industrial PLCs and ROS

For developers already working with ROS, the integration of industrial fieldbuses, I/Os, and functional safety into robotic applications often introduces unexpected challenges. ROS offers a flexible and modular software framework, although connecting it to industrial automation hardware typically requires additional integration layers and specialized knowledge.

This led to the idea of creating a solution that allows ROS developers to leverage a PLC where it excels, for example in deterministic control, industrial communication, and safety, while high performance computation and complex logic remain handled within ROS.

PLCnext Technology Architecture Overview

PLCnext Controls run PLCnext Linux, a real-time capable operating system that hosts the PLCnext Runtime. The Runtime manages deterministic process data and stores it in the Global Data Space (GDS).

Key architectural components :

  • PLCnext Linux: Yocto‑based embedded Linux
  • PLCnext Runtime (tasks, data handling, Axioline integration): Provides deterministic processing and the Global Data Space
  • Global Data Space (GDS): Central storage for process variables accessible from PLC programs and system apps
  • PLCnext Apps: Packaged software components that can be installed on the controller

PLCnext ROS Bridge

Concept

At its core, the PLCnext ROS Bridge is a custom ROS node with dedicated services running inside a Docker container, packaged as a PLCnext App. It provides a bidirectional communication gateway between the PLCnext Global Data Space (industrial side) and ROS topics (robotics side).

To illustrate this, consider a motor connected to the PLC via EtherCAT/FSoE or PROFINET/PROFIsafe. The motor, along with its associated safety functions, can be managed through simple PLC logic and represented by a set of variables. Depending on the implementation, these variables, such as setpoints, command velocities, etc., can be exposed to ROS. When the navigation stack publishes a command velocity, the ROS Bridge, as a subscriber to this topic, writes the received values to the corresponding variable on the PLC side. Likewise, information such as safety status or system state can be sent from the PLC to ROS and made available through a defined topic.

Commissioning Workflow

The ROS Bridge Node is generated through an automated code-generation process. This process is driven by the Interface Description File (IDF), which defines the PLC instance paths (variables) that should be exposed to ROS.

A typical build process performs the following steps:

  1. Building the ROS Packages
    • Parse the IDF and generate the source code for the topic, publisher and subscribers
    • Build the ROS Node
  2. Place the resulting binaries and gRPC dependencies into a Docker image with a minimal ros-core installation.
  3. Package the Docker image, together with required metadata, into a read-only PLCnext App.

The resulting App can be deployed to a PLCnext Controller using the Web-Based Management (WBM) interface. While it is possible to build everything in a local environment, the project is designed to be built via CI/CD. An example pipeline can also be found in the GitHub repository.

Runtime Behaviour

After installation, the App starts the container defined via the compose file. Inside this container, the generated ROS Node connects to the Global Data Space using the built gRPC client and then exposes the selected PLC variables via ROS publishers and subscribers. This enables ROS developers to integrate automation components, such as sensors, actuators, I/O modules, and fieldbus devices, into a ROS-based architecture through the GDS. Moreover, the Bridge sets up a set of services that enable users to read and write information at runtime.

Questions on Zero-Copy for Variable-Size Messages (PointCloud2) with Iceoryx in ROS 2

Hi everyone,

I am currently working on optimizing high-bandwidth sensor data transmission (specifically LiDAR point clouds) using ROS 2 and Iceoryx for zero-copy communication.

I have successfully set up the Iceoryx environment and confirmed zero-copy works for fixed-size types. However, I am facing challenges when applying this to variable-size messages, such as sensor_msgs/msg/PointCloud2.

As I understand it, Iceoryx typically requires pre-allocated memory pools with fixed chunks. In the case of PointCloud2, the data size can vary depending on the LiDAR’s points (in my case, around 5.2MB per message).

I have two specific questions:

1. Best practices for variable-size data like PointCloud2

How should we handle messages where the size is not strictly fixed at compile-time while still maintaining zero-copy benefits? Should we always pre-allocate the “worst-case” maximum size for the underlying buffers? If anyone has implemented this for sensor_msgs/msg/PointCloud2 or similar dynamic types, I would appreciate any advice or examples.

2. Tuning RouDi Configuration (size and count)

Regarding the roudi_config.toml (or the RouDi memory pool setup), what is the general rule of thumb for determining the optimal size and count?

For high-resolution LiDAR data:

  • How do you balance between the number of chunks (count) and the buffer size for each chunk to avoid memory exhaustion without being overly wasteful?

  • Are there any common pitfalls when setting these values for a system with multiple subscribers?

I’ve already got Iceoryx installed and basic IPC working, but I want to ensure my configuration is production-ready for large-scale sensor data.

Thank you in advance for your insights!

FusionCore, which is a ROS 2 Jazzy sensor fusion package (robot_localization replacement)

Hey everyone,
I’ve been working on FusionCore for the last few months… it’s a ROS 2 Jazzy sensor fusion package that aims to bridge the gap left by the deprecation of robot_localization.

There wasn’t anything user-friendly available for ROS 2 Jazzy. It merges IMU, wheel encoders, and GPS/GNSS into a single, reliable position estimate at 100Hz. No need for manual covariance matrices…. just one YAML config file.

  • It uses an Unscented Kalman Filter (UKF) with a complete 3D state…. and it’s not just a port of robot_localization.
  • It features native GNSS fusion in ECEF coordinates, so you won’t run into UTM zone issues.
  • It supports dual antenna heading right out of the box….
  • It automatically estimates IMU gyroscope and accelerometer bias.
  • It includes HDOP/VDOP quality-aware noise scaling, which means bad GPS fixes are automatically down-weighted.
  • It’s under the Apache 2.0 license, making it commercially safe.
  • And it’s built natively for ROS 2 Jazzy….. not just a port.

GitHub: https://github.com/manankharwar/fusioncore

I respond to issues within 24 hours. If you’re working on a wheeled robot with GPS on ROS 2 Jazzy and hit problems….. open an issue or reply here.

The first will be given by Steve Macenski (OpenNavigation), lead developer of the Nav2 system, widely regarded as the reference standard for autonomous robot navigation in ROS 2. The second will be delivered by Davide Faconti, creator of BehaviorTrees.CPP and Groot, tools that are extensively used for developing robotics applications based on Behavior Trees.

The school’s pedagogical approach is strongly practical and collaborative: participants will learn by doing, combining knowledge of artificial intelligence, control, and perception with their direct application in ROS 2, both in simulation environments and on real robotic platforms. Beyond its technical dimension, the school promotes intercultural collaboration and international teamwork, creating a dynamic environment for learning and experimentation.
This summer school is part of the iRoboCity2030 initiative, the robotics innovation network of the Community of Madrid, and represents a joint effort by the region’s leading universities and research centers to promote advanced training and knowledge transfer in robotics and artificial intelligence.

Polka: A unified node for all pointcloud pre-processing/merging

Hello folks,

Point cloud pre-processing including deskewing, merging, and filtering traditionally requires a chain of nodes working in tandem, many of which are no longer actively maintained. Setting up these individual filtering stages often consumes excessive CPU cycles and precious DDS bandwidth.

What if you had a single, low-latency node that could voxellize, deskew, downsample, and merge scans in one go? By passing only mission-critical features to your odometry nodes and downstream, you significantly reduce lag and bandwidth usage across your entire navigation or SLAM stack. A single node to accomplish this.

I developed Polka to solve this. It’s a drop-in replacement for multiple pre-processing nodes and if you need to save CPU, you can run the entire pipeline on your GPU.

Latency across both being ~40ms.

Current features:

  • Merge Pointclouds and laser scans

  • Input/output frame filtering.

  • Defined footprint, height, and angular box filters.

  • Voxel downsampling.

  • GPU acceleration support.

  • Deskewing Pointclouds (WIP)

I’d love your feedback, and if you find the project useful, please consider leaving a star on GitHub!

Mastering Nero – MoveIt2 Part II

Mastering Nero – MoveIt2 Part II

In the previous session, we built a complete MoveIt2 package from a URDF model using the MoveIt Setup Assistant, and realized motion planning and visual control of the robotic arm.

In this session, we will explain how to set up a co-simulation environment for MoveIt2 and Isaac Sim. By configuring the ROS Bridge, adjusting hardware interface topics, and integrating the URDF model, we will achieve seamless connection between the simulator and motion planning, providing a complete practical solution for robot algorithm development and system integration.

Abstract

Co-simulation of MoveIt2 and Isaac Sim

Tags

ROS2, MoveIt2, robotic arm, Nero

Repositories

Operating Environment

System: Ubuntu 22.04
ROS Version: Humble
Isaac Sim Version: 5.1

Download USD Model

We use the Nero USD model provided by AgileX Robotics:

cd ~/nero_ws/src
git clone https://github.com/agilexrobotics/agx_arm_sim

If you haven’t installed Isaac Sim or want to import your own URDF model, refer to:

Isaac_Sim Import PiPER URDF

Launch Isaac Sim

Navigate to the Isaac Sim folder, use the script to launch the ROS Bridge Extension, then click Start to launch Isaac Sim:

cd isaac-sim-standalone-5.1.0-linux-x86_64/
./isaac-sim.selector.sh

Then drag and drop the newly downloaded USD model into Isaac Sim to open it:

In the USD file, you need to add an ActionGraph for communication with the ROS side. The ActionGraph is as follows:

Configure ActionGraph

articulation_controller

Modify targetPrim according to actual conditions; targetPrim is generally /World/nero_description/base_link:

ros2_subscribe_joint_state

Modify topicName according to actual conditions; topicName must correspond to the URDF, here it is isaac_joint_commands:

ros2_publish_joint_state

Modify targetPrim and topicName according to actual conditions; targetPrim is generally /World/nero_description/base_link; topicName must correspond to the URDF, here it is isaac_joint_states:

After starting the simulation, use ros2 topic list in the terminal; the following topics can be viewed:

Modify MoveIt Package

Open nero_description.ros2_control.xacro and add topic parameters:

gedit nero_ws/src/nero_moveit2_config/config/nero_description.ros2_control.xacro

            <hardware>
                <!-- By default, set up controllers for simulation. This won't work on real hardware -->
                <!-- <plugin>mock_components/GenericSystem</plugin> -->
                <plugin>topic_based_ros2_control/TopicBasedSystem</plugin>
                <param name="joint_commands_topic">/isaac_joint_commands</param>
                <param name="joint_states_topic">/isaac_joint_states</param>
            </hardware>

Then save and compile the code, then launch MoveIt2:

cd ~/nero_ws
colcon build
source install/setup.bash
ros2 launch nero_moveit2_config demo.launch.py

-------------------------|------------------------------------------

═════════════════

INTELLIGENT MODEL ROUTER (v2.0)

═════════════════

Our multi-model routing system analyzes natural language instructions

in real-time using semantic classification algorithms, automatically

selecting the optimal language model for each specific task type.

For OCR tasks, the router selects DeepSeek-OCR-2B with 97% accuracy;

for manipulation tasks, it routes to Xiaomi-Robotics-0. This

intelligent selection reduces inference latency by 35% while

improving task success rates through model specialization.

═════════════════

TASK PLANNER (Layer 3 Architecture)

═════════════════

The Task Planner decomposes high-level natural language instructions

into executable subtasks using dependency graph analysis and

topological sorting. When a user requests “Clean the warehouse,”

the system generates a directed acyclic graph of subtasks

(navigate→identify→grasp→transport→place) with estimated durations

and parallel execution paths. This hierarchical planning reduces

complex mission failure rates by implementing checkpoint recovery

at each subtask boundary.

═════════════════

LEARNING SYSTEM (Layer 4 - Continuous Improvement)

═════════════════

Our parameter optimization engine maintains a vector database of

task execution outcomes, using collaborative filtering algorithms

to recommend optimal grip forces, approach velocities, and grasp strategies based on historical performance data.

For fragile object manipulation, the system has learned that 0.28N grip force with

12cm/s approach velocity yields 94% success rates across 127 similar

tasks, automatically adjusting robot parameters without human

intervention.

═════════════════

IOT SENSOR FUSION (Layer 2 - Environmental Context)

═════════════════

The API integrates multi-modal sensor streams (GPS coordinates,

LiDAR point clouds, IMU orientation, temperature/humidity readings)

into the inference pipeline through Kalman-filtered sensor fusion.

This environmental awareness enables context-aware decision making -

for example, automatically reducing grip force when temperature

sensors detect a hot object, or adjusting navigation paths based

on real-time LiDAR obstacle detection with sub-10cm accuracy.

═════════════════

ENTERPRISE API INFRASTRUCTURE

═════════════════

We’ve implemented a complete enterprise API layer including X-API-Key

authentication with SHA-256 hashing, JWT token-based session

management, per-organization rate limiting with token bucket

algorithms, and comprehensive audit logging. The system supports

multi-tenant deployment with complete data isolation between

organizations, enabling commercial deployment scenarios that raw

model weights cannot address.

═════════════════

EDGE DEPLOYMENT (Global Low-Latency)

═════════════════

Our Cloudflare Worker deployment distributes inference across 200+

global edge locations using Anycast routing, achieving <50ms response

times from anywhere in the world through intelligent geo-routing.

The serverless architecture eliminates cold start latency entirely

while providing automatic DDoS protection and 99.99% uptime SLA -

critical capabilities for production robotics deployments that

require sub-100ms control loop response times.

═════════════════

MODEL REGISTRY & PERFORMANCE ANALYTICS

═════════════════

The Model Registry maintains real-time performance metrics including

per-model success rates, p50/p95/p99 latency percentiles, and

cost-per-inference calculations across different hardware

configurations. This telemetry enables data-driven model selection

and automatic A/B testing of model versions, ensuring optimal

performance as your Xiaomi-Robotics-0 model evolves.

═════════════════

ROBOT CONTROL API

═════════════════

We provide RESTful endpoints for real-time robot state querying

(joint angles, gripper position, battery telemetry) and action

execution with safety interlocks. The action execution pipeline

includes collision detection through bounding box overlap

calculations, emergency stop capabilities with <10ms latency, and

execution confirmation through sensor feedback loops - essential

safety features absent from the base model inference API.

MULTI-AGENT COORDINATION

Enable multiple robots to collaborate on complex tasks. Master

agents break down objectives and distribute work to worker agents

with shared memory and handoff zones.

→ Swarm intelligence, task delegation, conflict resolution

FEW-SHOT LEARNING

Robots learn new tasks from just 3-5 demonstrations instead of

programming. Skills adapt to user preferences and improve

continuously from execution feedback.

→ Learn from demonstrations, skill composition, personalisation.

ADVANCED PERCEPTION

Multi-modal sensor fusion (camera, depth, LiDAR, thermal) with

6DOF pose estimation. Detect humans, recognize gestures, predict

motion, and calculate optimal grasp points.

→ 3D scene understanding, human detection, gesture recognition

SAFETY LAYER

Continuous safety validation with 50ms checks. Force/torque

limits, human proximity detection, collision prediction,

configurable safety zones, and full audit logging for compliance.

→ Real-time monitoring, emergency stop, collision prediction

GESTURE CONTROL

Real-time hand gesture recognition for intuitive robot control.

Wave to pause/stop, point to direct attention, draw paths for

navigation. Works from 0.5-3 meters with 95%+ accuracy.

→ Wave to stop, point to indicate location

VOICE WAKE WORD

Always-listening voice activation with custom wake words.

Natural language command parsing with intent extraction. Supports

multiple languages and voice profiles for personalised interactions.

→ “Hey Robot, [command]”

PROGRESS UPDATES

Real-time task progress reporting with time estimation.

Subscribable WebSocket streams for live updates. Milestone

notifications when tasks reach defined checkpoints.

→ “Task 60% complete, 2 minutes remaining”

FAILURE RECOVERY

Intelligent error recovery with strategy adaptation. If grasp

fails, automatically try different angles, grip forces, or

approaches. Escalates to human operator only after exhausting

recovery options.

→ Auto-retry with different angles/strategies

TASK TEMPLATES

Pre-configured task sequences for common workflows. Schedule-based

activation with variable substitution. Templates can be nested,

parameterized, and shared across robot fleets.

→ “Morning routine”, “Closing procedures”

PHYSICS-AWARE PLANNING

Motion planning with real-world physics simulation. Detects

impossible trajectories, unstable grasps, and collision risks

before execution. Integrates with MuJoCo and Isaac Sim.

→ Simulate before execute, avoid physics violations

REAL-TIME SAFETY

Runtime safety monitoring with microsecond latency. Dynamically

adjusts robot speed based on proximity to humans. Emergency stop

with guaranteed response time under 10ms.

→ Continuous monitoring, dynamic speed adjustment

SEMANTIC NAVIGATION

Navigate using natural language landmarks instead of coordinates.

Understand spatial relationships (“next to the table”, "behind

the sofa"). Dynamic path recalculation when obstacles appear.

Thank you in advance for your consideration and feedback.

Sincere Regards

Introducing the Connext Robotics Toolkit for ROS 2

Hi ROS 2 Community,

I’m pleased to announce that RTI released enhanced support for ROS 2 and rmw_connextdds today. The new Connext Robotics Toolkit makes it much easier for ROS users to take advantage of Connext and DDS features to improve their development experience.

As many of you know, RTI has supported ROS 2 since the very beginning by providing our core DDS implementation at no charge for non-commercial use. The Connext Robotics Toolkit extends that support to our full Connext Professional product. This includes our broader platform around DDS – things like network tuning and debugging tools, system observability, and diverse network support, from shared memory to WAN.

In addition, we’re expanding our free license to include commercial prototyping. This means startups and other product teams building ROS-based systems can now take advantage of Connext at no charge. Starting with production-grade communication infrastructure will make it easier to scale from prototype to deployment.

The Connext Robotics Toolkit is currently available for Kilted Kaiju and will be available for Lyrical Luth upon its release. If you’re exploring ways to leverage ROS in commercial systems or looking at RMW options beyond the default, you can find more details and installation instructions here: Connext Robotics Toolkit for ROS | RTI

Happy to answer questions or discuss with anyone interested.

Per-robot economic settlement for industrial ROS2 fleets

As ROS2 fleets move into commercial deployments serving external clients, one infrastructure gap is shared economic verification between the fleet operator and their customer. The operator’s internal logs don’t give the client independent verification of what work was completed, leading to manual reconciliation and disputes as fleets scale.

Built a settlement layer that monitors ROS2 lifecycle events and generates verified timestamped records per robot per completed task. Both operator and client can verify independently. Each robot builds a portable work history over time useful for service billing, equipment valuation, and proving utilization to potential customers.

Already compatible with standard ROS2 lifecycle management. Integration details here:https://github.com/FoundryNet/foundry_net_MINT/blob/main/FoundryNet%20API%20Client/foundry-client.py

Interested in feedback from anyone deploying ROS2 fleets commercially and dealing with the billing side of multi-client operations.

Cheers!

[Show and Tell] ROS 2 Blueprint Studio: Visual Node Editor & Boilerplate Generator (Alpha)

Hi everyone!

Like many of us, I appreciate the power and flexibility of ROS 2, but I’ve always found the amount of manual boilerplate to be a bottleneck for rapid development. Keeping track of all the configuration details making sure CMakeLists.txt and package.xml are perfectly synced, or manually wiring launch files and topic connections takes a significant amount of time. I wanted to find a way to automate this infrastructure setup so I could focus purely on writing the actual robotics logic.

To solve this, I started building ROS 2 Blueprint Studio a visual node-based editor (inspired by Unreal Engine Blueprints) designed to take the routine off your shoulders.

Under the Hood (Architecture) I tried to avoid any “black magic” and stick entirely to standard ROS 2 practices:

1. Code Generation & Build System The studio doesn’t compile the code itself; it acts as a smart templating engine. Creating a standard node generates a base C++ template. If you duplicate a node (from the palette or canvas), it creates an independent file with a new name and copied code. Modifying the copy doesn’t break the parent. For the actual build, it relies on standard colcon build under the hood.

2. File Watcher & Dependency Tree To build the dependency tree, I wrote a custom FileWatcher. Before building, it scans the files to check for includes and node communication. For performance, it only parses files that have been modified. (I realize this might theoretically cause “phantom connections” on massive graphs, so I plan to add a forced full-rebuild mode in the future).

3. Topic Routing (Two Approaches) Node linking currently works in two modes:

  • Hardcoded (Bottom-Up): If publisher and subscriber topic names are explicitly hardcoded in your C++ or Python files, the UI detects this and automatically draws a visual “locked” wire between them.

  • Visual (Top-Down): You can define the topic name only on the publisher, drag a visual wire to a subscriber, and the FileWatcher will find a special placeholder in the subscriber’s code and automatically replace it with the publisher’s topic name. (Full disclosure: the visual routing is still a bit unstable and not recommended for huge projects yet, but I’m refining it).

0316

4. Runtime Environment (Docker) I chose Docker (osrf/ros:humble-desktop) as the execution environment. Why?

  • Setting up ROS 2 natively on Windows is a special kind of pain.

  • It provides painless deployment and saves you from dependency hell when migrating to future ROS versions.

  • You can send your project folder to someone who doesn’t even have ROS installed, and their system will build and run your entire architecture in just a few clicks.

The Ask: Roast My Architecture The project is currently in early alpha. Honestly, my biggest doubts right now are around the core architecture and the automated build system (package and launch file generation).

I would be incredibly grateful if experienced ROS architects could take a look at the repo, point out my blind spots, and give me some harsh architectural critique. I’d much rather rebuild the foundation now than drag architectural flaws into a full release.

Source code here: GitHub - NeiroEvgen/ros2-blueprint-studio · GitHub

Any feedback is highly appreciated!

mcp-ros2-logs — let AI agents debug your ROS2 logs across nodes

mcp-ros2-logs is an open-source MCP server that merges ROS2 log files from multiple nodes into a unified timeline and exposes query tools for AI agents like Claude, GitHub Copilot, and Cursor.

The problem: ROS2 writes each node’s logs to a separate file. Debugging a cascading failure across sensor_driver -> collision_checker -> motion_planner means manually correlating timestamps across 3+ files.

What this does: Install it with pipx install mcp-ros2-logs, register it with your AI assistant, and ask natural language questions like:

  • “show me all errors with 5 messages of context around each”
  • “compare good_run vs bad_run — what changed?”
  • “detect anomalies in this run”
  • “correlate errors with bag topics — what was happening on /scan when the planner crashed?”

Features:

  • 12 MCP tools: query logs, node summaries, timelines, run comparison, anomaly detection, bag file parsing, log-to-bag topic correlation, live tailing
  • Parses ROS2 bag files (.db3/.mcap) without ROS2 installed — extracts topic metadata for correlation with log errors
  • Statistical anomaly detection: rate spikes, new error patterns, severity escalations, silence gaps, error bursts
  • Supports custom RCUTILS_CONSOLE_OUTPUT_FORMAT
  • Works with Claude Code, VS Code Copilot, Cursor, and any MCP-compatible client
  • No ROS2 installation required — it just reads files from disk

Example workflow: Point the agent at a run where a lidar USB connection dropped. It loads the logs, correlates the errors with bag topic data, and reconstructs the full causal chain: USB timeout → /scan messages stopped → collision_checker failed → motion_planner aborted. The whole analysis takes about 10 seconds.

GitHub: GitHub - spanchal001/mcp-ros2-logs: Give AI agents the ability to debug ROS2 logs across nodes — MCP server, no ROS2 install required · GitHub
PyPI: pipx install mcp-ros2-logs

Would love feedback from anyone doing multi-node debugging or working with bag files.

Rewire — stream ROS 2 topics to Rerun with zero ROS 2 build dependencies

Title: Rewire — stream ROS 2 topics to Rerun with zero ROS 2 build dependencies

Hi all,

I’ve been working on Rewire, a standalone bridge that streams live ROS 2 topics to
Rerun for real-time visualization. I wanted to share it here and get feedback from the
community.

The problem it solves

Setting up visualization tooling in ROS 2 often means pulling in dependencies,
building packages, and dealing with middleware configuration. I wanted something that just works — point it at a DDS/Zenoh network and start visualizing.

How it works

Rewire is a single Rust binary that speaks DDS and Zenoh wire protocols directly. It’s not a ROS 2 node —
it doesn’t join the ROS graph or require any ROS 2 installation. It acts as a passive observer.

curl -fsSL https://rewire.run/install.sh | sh
rewire record -a    # subscribe to all topics

What’s supported

  • 53 type mappings across sensor_msgs, geometry_msgs, nav_msgs, tf2_msgs, vision_msgs, std_msgs, and rcl_interfaces — including Image, PointCloud2, LaserScan, TF, Odometry, Detection2D/3DArray, and more.
  • Custom message mappings — map any ROS 2 message type to Rerun archetypes via a JSON5 config file, no recompilation.
  • URDF visualization — loads from /robot_description, resolves meshes via AMENT_PREFIX_PATH.
  • Full TF tree — static + dynamic transforms with coordinate frame visualization
  • Per-topic diagnostics — Hz, bandwidth, drops, and latency rendered as Rerun Scalars.
  • Topic filtering — glob-based include/exclude patterns.

Platforms

Linux (x86_64, aarch64) and macOS (Intel + Apple Silicon).

Install options

  • Install script: curl -fsSL https://rewire.run/install.sh | sh
  • prefix.dev: pixi global install -c rewire rewire
  • APT repository for Debian/Ubuntu

I’d love to hear your thoughts — especially around which message types or workflows you’d want supported next. If you run into issues, feedback is very welcome.
