When May I Help You? On The Effect of Proactivity on Group Human-Robot Collaboration
Thomas Vitry, Vanessa Maeder, Kieran von Valeburg +6
Robot initiative is a central challenge in multi-party human-robot collaboration. A robot that contributes without being addressed may provide timely support, but it may also disru…
Towards Learning a Generalizable 3D Scene Representation from 2D Observations
Martin Gromniak, Jan-Gerrit Habekost, Sebastian Kamp +2
We introduce a Generalizable Neural Radiance Field approach for predicting 3D workspace occupancy from egocentric robot observations. Unlike prior methods operating in camera-centr…
Knowing the Facts but Choosing the Shortcut: Understanding How Large Language Models Compare Entities
Hans Hergen Lehmann, Jae Hee Lee, Steven Schockaert +1
Large Language Models (LLMs) are increasingly used for knowledge-based reasoning tasks, yet understanding when they rely on genuine knowledge versus superficial heuristics remains…
Robots with Attitudes: Influence of LLM-Driven Robot Personalities on Motivation and Performance
Dennis Becker, Kyra Ahrens, Connor Gäde +2
Large language models enable unscripted conversations while maintaining a consistent personality. One desirable personality trait in cooperative partners, known to improve task per…
Keypoint-based Diffusion for Robotic Motion Planning on the NICOL Robot
Lennart Clasmeier, Jan-Gerrit Habekost, Connor Gäde +2
We propose a novel diffusion-based action model for robotic motion planning. Commonly, established numerical planning approaches are used to solve general motion planning problems,…
Pointing-Guided Target Estimation via Transformer-Based Attention
Luca Müller, Hassan Ali, Philipp Allgeuer +2
Deictic gestures, like pointing, are a fundamental form of non-verbal communication, enabling humans to direct attention to specific objects or locations. This capability is essent…
