Developing a context-aware system for providing intelligent robot services

To realize the vision of ubiquitous computing, it is important to develop a context-aware system which can help ubiquitous agents, services, and devices become aware of their contexts. Context-aware system is required to be capable of configuring appropriate context model and managing it through the context manipulation. In this paper, we propose the context space and the conceptual structure for context acquisition, representation, and utilization. We also describe how this conceptual structure is implemented in the service robot area. As the result of the research, we developed the CAMUS (Context-Aware Middleware for URC Systems) which is a context-aware server framework for a network-based intelligent robot system and applied it to the field test.
