Ros Atkins on... The White House claims on BBC Gaza coverage
On Tuesday White House Press Secretary Karoline Leavitt launched an attack on the BBC's coverage of reports that Israeli forces had killed Palestinians near an aid distribution centre in Gaza. She claimed that the BBC took down a story after reviewing footage. The BBC has said the claim is completely wrong and that it stands by its journalism. Ros Atkins from BBC Verify takes a look at the facts.

AWML: An Open-Source ML-based Robotics Perception Framework to Deploy for ROS-based Autonomous Driving Software
In recent years, machine learning technologies have played an important role in robotics, particularly in the development of autonomous robots and self-driving vehicles. As the industry matures, robotics frameworks like ROS 2 have been developed and provides a broad range of applications from research to production. In this work, we introduce AWML, a framework designed to support MLOps for robotics. AWML provides a machine learning infrastructure for autonomous driving, supporting not only the …

A first look at ROS~2 applications written in asynchronous Rust
The increasing popularity of the Rust programming language in building robotic applications using the Robot Operating System (ROS~2) raises questions about its real-time execution capabilities, particularly when employing asynchronous programming. Existing real-time scheduling and response-time analysis techniques for ROS~2 focus on applications written in C++ and do not address the unique execution models and challenges presented by Rust's asynchronous programming paradigm. In this paper, we a…

ROS 2 Agnocast: Supporting Unsized Message Types for True Zero-Copy Publish/Subscribe IPC
Robot applications, comprising independent components that mutually publish/subscribe messages, are built on inter-process communication (IPC) middleware such as Robot Operating System 2 (ROS 2). In large-scale ROS 2 systems like autonomous driving platforms, true zero-copy communication -- eliminating serialization and deserialization -- is crucial for efficiency and real-time performance. However, existing true zero-copy middleware solutions lack widespread adoption as they fail to meet three…

Efficient scheduling in redundancy systems with general service times
We characterize the impact of scheduling policies on the mean response time in nested systems with cancel-on-complete redundancy. We consider not only redundancy-oblivious policies, such as FCFS and ROS, but also redundancy-aware policies of the form $Π$ 1 -- $Π$ 2 , where $Π$ 1 discriminates among job classes (e.g., least-redundant-first (LRF), most-redundantfirst (MRF)) and $Π$ 2 discriminates among jobs of the same class. Assuming that jobs have independent and identically distributed (i…

Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
We report initial observations aimed at the characterization of a third interstellar object candidate. This object, 3I/ATLAS -- also C/2025 N1 (ATLAS) -- , was discovered on 2025 July 1 UT and has an orbital eccentricity of $e\sim6.2$, perihelion of $q\sim 1.35$ au, inclination of $\sim175^\circ$, and hyperbolic velocity of $V_\infty\sim 60$ km s$^{-1}$. 3I/ATLAS has an absolute magnitude of $H_V\sim12$, which corresponds to a nuclear radius of $\sim10\text{ km}$, assuming an asteroid-like albe…

HAMMER: Heterogeneous, Multi-Robot Semantic Gaussian Splatting
3D Gaussian Splatting offers expressive scene reconstruction, modeling a broad range of visual, geometric, and semantic information. However, efficient real-time map reconstruction with data streamed from multiple robots and devices remains a challenge. To that end, we propose HAMMER, a server-based collaborative Gaussian Splatting method that leverages widely available ROS communication infrastructure to generate 3D, metric-semantic maps from asynchronous robot data-streams with no prior knowl…

Regression Testing Optimization for ROS-based Autonomous Systems: A Comprehensive Review of Techniques
Regression testing plays a critical role in maintaining software reliability, particularly for ROS-based autonomous systems (ROSAS), which frequently undergo continuous integration and iterative development. However, conventional regression testing techniques face significant challenges when applied to autonomous systems due to their dynamic and non-deterministic behaviors, complex multi-modal sensor data, asynchronous distributed architectures, and stringent safety and real-time constraints.

ROS-related Robotic Systems Development with V-model-based Application of MeROS Metamodel
As robotic systems grow increasingly complex, heterogeneous, and safety-critical, the need for structured development methodologies becomes paramount. Although frameworks like the Robot Operating System (ROS) and Model-Based Systems Engineering (MBSE) offer foundational tools, they often lack integration when used together. This paper addresses that gap by aligning the widely recognized V-model development paradigm with the MeROS metamodel SysML-based modeling language tailored for ROS-based sy…

Structural results on idealistic equivalence relations
We address some fundamental problems concerning the structure of idealistic equivalence relations. In particular, we show that, under analytic determinacy, there are continuum many idealistic analytic equivalence relations that are not classwise Borel isomorphic to an orbit equivalence relation. Moreover, we also discuss alternative formulations of the E1 conjecture, and present an elementary counterexample to one of its earliest variants proposed by Hjorth and Kechris in 1997.

VAULT: A Mobile Mapping System for ROS 2-based Autonomous Robots
Localization plays a crucial role in the navigation capabilities of autonomous robots, and while indoor environments can rely on wheel odometry and 2D LiDAR-based mapping, outdoor settings such as agriculture and forestry, present unique challenges that necessitate real-time localization and consistent mapping. Addressing this need, this paper introduces the VAULT prototype, a ROS 2-based mobile mapping system (MMS) that combines various sensors to enable robust outdoor and indoor localization.…

Work-in-Progress: Multi-Deadline DAG Scheduling Model for Autonomous Driving Systems
Autoware is an autonomous driving system implemented on Robot Operation System (ROS) 2, where an end-to-end timing guarantee is crucial to ensure safety. However, existing ROS 2 cause-effect chain models for analyzing end-to-end latency struggle to accurately represent the complexities of Autoware, particularly regarding sync callbacks, queue consumption patterns, and feedback loops. To address these problems, we propose a new scheduling model that decomposes the end-to-end timing constraints o…

Large Language Models (LLMs) have experienced great advancements in the last year resulting in an increase of these models in several fields to face natural language tasks. The integration of these models in robotics can also help to improve several aspects such as human-robot interaction, navigation, planning and decision-making.
