Desire-Driven Reasoning considering Status-Based Knowledge Description for Personal Care Robots

One option to face the aging society and caring force shortage is to develop intelligent robots capable of caring for people while no one is available. This paper investigates how specific commands (e.g. serve a cup of water) can be reasoned from abstracted desires (e.g., thirst) while caring for bedridden individuals with robots. The key to solving the problem is a status-based knowledge description, which is expendable considering complex and large quantify of available household operations and items. Based on such a description, a reasoning system is presented to identify suitable actions given an abstracted need. Finally, we evaluate the reasoning system with our personal care robot KUT-PCR in a real household domain.
