Abstract
As robots begin to enter our daily lives, we need advanced knowledge representations and associated reasoning capabilities to enable them to understand and model their environments. Considering the presence of humans in such environments, and therefore the need to interact with them, this need comes with additional requirements. Indeed, knowledge is no longer used by the robot for the sole purpose of being able to act physically on the environment but also to communicate and share information with humans. Therefore knowledge should no longer be understandable only by the robot itself, but should also be able to be narrative-enabled.
In this presentation, I will first introduce a task to assess cognitive architecture in the context of Human-Robot Interaction and the corresponding implemented architecture. In a second time, I will introduce the main components of the architecture, their links, and their features making them suitable for Human-Robot Interaction applications. Among these components, I will present the semantic knowledge base in the form of an ontology, an ontology-based Referring Expression Generation algorithm to describe entities of the environment, a method the estimate communicate feasibility and cost during a task planning process, and finally a geometrical situation assessment component to extract symbol facts from perception inputs.
Speaker's bio
Guillaume Sarthou is a Postdoctoral researcher in Robotics at the Institute for Artificial Intelligence of Bremen, Germany. He received his PhD in robotics in 2021 for which he focused on knowledge representation and exploitation for Human-Robot Interaction. His research interests are about cognitive architecture applied to Human-Robot Interaction in general going from the assessment of the situation to symbolic task planning with a strong link to the knowledge representation of both the robot and the humans it interacts with.
