A Goal Triggering Mechanism for Continuous Human-Robot Interaction

The deployment of autonomous robots capable to both socially interact and proactively offer support to human users in a common life scenario remains challenging despite the recent technical advancements. For instance, research for endowing autonomous robots with the capability of acting in “non-ideal” and partially observable environments as well as socially interacting with humans is still an area in which improvements are specifically needed. To this aim, this paper elaborates on the need for integrating different Artificial Intelligence (AI) techniques to foster the development of personal robotic assistants continuously supporting older adults. Recently, the authors have been working on proposing an AI-based cognitive architecture that integrates knowledge representation and automated planning techniques in order to endow assistive robots with proactive and context situated abilities. This paper particularly describes a goal triggering mechanism to allow a robot to reason over the status of the user and the living environment with the aim of dynamically generating high-level goals to be planned accordingly.
