In recent years, motivated by the emergence of ubiquitous computing technologies, a new class of networked robots, ubiquitous robots, has been introduced. The Ubiquitous Robotic Companion (URC) is our conceptual vision of ubiquitous service robots that provide users with the services they need, anytime and anywhere in ubiquitous computing environments. To realize the vision of URC, one of the essential requirements for robotic systems is to support ubiquity of services: that is, a robot service must be always available even though there are changes in the service environments. Specifically robotic systems need to be automatically interoperable with sensors and devices in current service environments, rather than statically preprogrammed for them. In this paper, the design and implementation of a semantic-based ubiquitous robotic space (SemanticURS) is presented. SemanticURS enables automated integration of networked robots into ubiquitous computing environments exploiting Semantic Web Services and AI-based planning technologies.

URC(Ubiquitous Robotic Companion)는 기존로봇에 네트워크 및 정보 기술을 접목한 지능형 서비스 로봇의 새로운 개념으로서, 언제, 어디서나 나와 함께하며, 나에게 필요한 서비스를 제공하는 네트워크 기반 로봇이다. URC 개념이 구현되기 위해서는 유비퀴터스 네트워크 또는 센서 네트워크, 고성능 로봇용 서버 등과 같은 하드웨어 인프라가 구축되어 있어야 하며, 이러한 인프라 상에서 구동되는 소프트웨어 인프라가 필요하다. 소프트웨어 로봇은 이러한 소프트웨어 인프라에 해당하며, '유비퀴터스 네트워크 환경에서 언제 어디서나 상황에 맞는 정보와 서비스를 능동적으로 제공하는 새로운 개념의 지능형 소프트 웨어'이다. 본 고에서는 이러한 소프트웨어 로봇의 개념과 이 개념을 지원하기 위한 시스템에 대해 논의 한다.

We introduce new type of networked robot, Ubiquitous Robotic Companion (URC), embedded with ATLAS Service-oriented architecture for enhancing the space sensing capability. URC is a network-based robotic system developed by ETRI. For years of experience in deploying service with ATLAS sensor platform for elder and people with special needs in smart houses, we need networked robots to assist elder people in their successful daily living. Recently, pervasive computing technologies reveals possibilities of networked robots in smart spaces, consist of sensors, actuators and smart devices can collaborate with the other networked robot as a mobile sensing platform, a complex and sophisticated actuator and a human interface. This paper provides our experience in designing and implementing system architecture to integrate URC robots in pervasive computing environments using the University of Florida's ATLAS service-oriented architecture. In this paper, we focus on the integrated framework architecture of URC embedded with ATLAS platform. We show how the integrated URC system is enabled to provide better services which enhance the space sensing of URC in the smart space by applying service-oriented architecture characterized as flexibility in adding or deleting service components of Ubiquitous Robotic Companion.

In this paper, We propose the real-time monitor and control mechanism based-on web service for intelligent robot called URC(Ubiquitous Robotic Companion). URC is intelligent robot designed to interact with external digital device that can communicate through wire or wireless. In this paper, we designed the result of this study into the target robot called NETTORO and proved its practical worth. we optimized web-service technology in Embedded system environment so that can monitor and control indoors in remote place through acquired information from various sensors / actuators and then we designed. Also, we described command port to WSDL, so that can apply variously such as web server or application program in AXIS engine through gSOAP transmission protocol.

In this paper, We are proposed the real-time monitor and control mechanism for intelligent robot called URC(Ubiquitous Robotic Companion). URC are intelligent robots designed as to interact with external digital device that can communicate through wire or wireless by integration the network and information technology into traditional robot. In this paper, we implemented the result of this study into the target robot called ISSAC4 and proved its practical worth. We designed it as be able to control on remote by such web browser as anywhere and anytime that show a status information for several controllers, devices, actuators and sensors of robot and guarantee a continuity of real-time image transferring by Client-Pull method and moving control of robot.
