This paper is an extension of the authors’ earlier publication proposing ubiquitous
robotic space [1]. In the previous work, authors collaborated to propose a novel
robotic service framework. The proposed robotic service framework comprises three conceptual
spaces: physical, semantic, and virtual space, which we call a ubiquitous robotic
space collectively. We implemented a prototype robotic security application in an office environment,
which confirmed that the proposed framework is an efficient tool for developing
a robotic service employing IT infrastructure, particularly for integrating heterogeneous
technologies involved and dealing with inherent complexity found in robotic platforms.
The proposed ubiquitous robotic space architecture is further applied to a large scale artificial
environment, which is crowded with hundreds of visitors. This experimental trial
proves further the usefulness of the proposed architecture since virtually no modification
of the original service architecture is required.
