Leveraging Foundation Models for Enhancing Robot Perception and Action

Reihaneh Mirjalili

This thesis investigates how foundation models can be systematically leveraged to enhance robotic capabilities, enabling more effective localization, interaction, and manipulation in unstructured environments. The work is structured around four core lines of inquiry, each addressing a fundamental challenge in robotics while collectively contributing to a cohesive framework for semantics-aware robotic intelligence.

Technical Development of a Semi-Autonomous Robotic Partition

Binh Vinh Duc Nguyen, Andrew Vande Moere

This technical description details the design and engineering process of a semi-autonomous robotic partition. This robotic partition prototype was subsequently employed in a longer-term evaluation in-the-wild study conducted by the authors in a real-world office setting.

Cops and Robbers on Dynamic Graphs: Offline and Online Case

Stefan Balev, Juan Jiménez Laredo, Ioannis Lamprou et al.

We examine the classic game of Cops and Robbers played on models of dynamic graphs, that is, graphs evolving over discrete time steps. At each time step, a graph instance is generated as a subgraph of the underlying graph of the model. The cops and the robber take their turns on the current graph instance. The cops win if they can capture the robber at some point in time. Otherwise, the robber wins. In the offline case, the players are fully aware of the evolution sequence, up to some finite time horizon T. We provide a O(n 2k+1 T) algorithm to decide whether a given evolution sequence for an underlying graph with n vertices is k-cop-win via a reduction to a reachability game. In the online case, there is no knowledge of the evolution sequence, and the game might go on forever. Also, each generated instance is required to be connected. We provide a nearly tight characterization for sparse underlying graphs, i.e., with at most linear number of edges. We prove λ + 1 cops suffice to capture the robber in any underlying graph with n − 1 + λ edges. Further, we define a family of underlying graphs with n−1+λ edges where λ−1 cops are necessary (and sufficient) for capture.

Defining a Precipitation Stable Isotope Framework in the Wider Carpathian Region

Viorica Nagavciuc, Aurel Perșoiu, Carmen-Andreea Bădăluță et al.

The eastern part of Europe is very poorly represented in the Global Network for Isotopes in Precipitation (GNIP) database, mainly because the monitoring of the stable isotopes in precipitation started only recently compared with other regions. In this respect, the main objective of this article is to fill the gap in the GNIP database over the eastern part of Europe and show the temporal variability and potential drivers of an extended network of δ18O values in precipitation collected from 27 locations in Romania and the Republic of Moldova. We also present the first high-resolution map of the spatio-temporal distribution of δ18O values in precipitation in Romania and the Republic of Moldova, according to an observational dataset. According to our results, the stations from western and northern Romania tend to have LMWLS with higher values than those from southwestern Romania. The monthly variation of the δ18O and δ2H showed a clearly interannual variation, with distinct seasonal differences, following the seasonal temperatures. The analysis of the spatial distribution of stable isotopes in precipitation water was made on the basis of both observational data and modeled data. This allowed us to study the origin of the air moisture and the interaction with regional and local patterns and to analyze the link between the spatial δ18O variations and the large-scale circulation patterns on a seasonal scale.

Design of a robot for the automatic charging of an electric car

Damien Chablat, Riccardo Mattacchione, Erika Ottaviano

In this paper, a robot with parallel architecture is proposed for charging an electric vehicle having the charging socket on its front side. Kinematic models are developed to design the robot for a given workspace that corresponds to the car's plug placements. A demonstrator composed by commercial components is shown.

Autonomous Driving Data Chain & Interfaces

Benjamin Kahl

Recent developments in autonomous driving technology have proven that map data may be used, not only for general routing purposes, but also for to enhance and complement common sensor data. This document reviews the most commonly used interfaces and formats at each step of a selfhealing map data chain.

Design and Construction of Unmanned Ground Vehicles for Sub-Canopy Plant Phenotyping

Adam Stager, Herbert G. Tanner, Erin E. Sparks

Unmanned ground vehicles can capture a sub-canopy perspective for plant phenotyping, but their design and construction can be a challenge for scientists unfamiliar with robotics. Here we describe the necessary components and provide guidelines for designing and constructing an autonomous ground robot that can be used for plant phenotyping.

Modified Self-Organized Task Allocation in a Group of Robots

Chang Liu

This paper introduces a modified self-organized task allocation algorithm, where robots are assigned to pick up one of the two types of object. This paper also demonstrates both algorithms by showing the simulation results of the conventional self-organized task allocation algorithm and the simulation results of its modification.

Semi-Analytic Method for SINS Attitude and Parameters Online Estimation

Lubin Chang

In this note, the attitude and inertial sensors drift biases estimation for Strapdown inertial navigation system is investigated. A semi-analytic method is proposed, which contains two interlaced solution procedures. Specifically, the attitude encoding the body frame changes and gyroscopes drift biases are estimated through attitude estimation while the attitude encoding the constant value at the very start and accelerometers drift biases are determined through online optimization.

Robot Planning with Mathematical Models of Human State and Action

Anca D. Dragan

Robots interacting with the physical world plan with models of physics. We advocate that robots interacting with people need to plan with models of cognition. This writeup summarizes the insights we have gained in integrating computational cognitive models of people into robotics planning and control. It starts from a general game-theoretic formulation of interaction, and analyzes how different approximations result in different useful coordination behaviors for the robot during its interaction with people.

Results of the Survey: Failures in Robotics and Intelligent Systems

Johannes Wienke, Sebastian Wrede

In January 2015 we distributed an online survey about failures in robotics and intelligent systems across robotics researchers. The aim of this survey was to find out which types of failures currently exist, what their origins are, and how systems are monitored and debugged - with a special focus on performance bugs. This report summarizes the findings of the survey.

A MATHEMATICAL MODELING OF CAMPUS INFORMATION SYSTEM

S. STALIN KUMAR, G. MARIMUTHU

An H-magic labeling in a H-decomposable graph G is a bijection f : V (G) ∪ E(G) → {1, 2, ..., p + q} such that for every copy H in the decomposition, \sum\limits_{v∈V (H)}{f(v)}+\sum\limits_{e∈E(H)}{ f(e)} is constant. f is said to be H-V -super magic if f(V (G)) = {1, 2, ..., p}. Suppose that V (G) = U(G) ∪ W(G) with |U(G)| = m and |W(G)| = n. Then f is said to be H-V -super-strong magic labeling if f(U(G)) = {1, 2, ..., m} and f(W(G)) = {m + 1, m + 2, ...,(m + n = p)}. A graph that admits a H-V -super-strong magic labeling is called a H-V -super-strong magic decomposable graph. In this paper, we pay our attention to provide a mathematical modeling of campus information system.
