In Human-Robot Collaboration, failures that are not explained or handled with alternative strategies can undermine user trust and interaction quality. Despite recent advances in LLM-based task planning, failures are often treated as terminal events, leading to non-transparent robot behaviors. This work investigates how...

In human-robot interaction, achieving a goal may require a robot to engage in competitive behaviors toward its human partner. In some cases, it is important for the robot to balance firmness with an amicable attitude to avoid causing discomfort to the user. In others, it might be necessary to push the user to act more...

Abstract concepts pose a fundamental challenge for multimodal interactive systems, as they cannot be grounded in single perceptual features or fixed motor patterns; instead, they require abstraction across perception, action, language, and affect. Examples include superordinate categories (e.g., animal, tool), generali...
