Abstract

Our focus is the development of software for controlling autonomous robots. In particular, we are concerned with the problem of grounding representations - creating representations which endow the agent with a meaningful understanding of the problem at hand. For most tasks, the development of an appropriate representation (e.g. world models, ontologies, schemas for decision-making and action) is a laborious process in which the developer handcrafts the representation for the particular control problem. The quality of the resultant representation is too dependent upon the designer's experience. Such agents can lack the capability to cope with, or adapt to, circumstances that were not anticipated by the developer. Despite the large labor costs incurred through handcrafting representation, and the cost of redesign when unanticipated circumstances force changes to agent software, there exist few methods for guiding the developer through this process. We present a preliminary methodology for designing and grounding representations.
