URC(Ubiquitous Robotic Companion)는 기존 로봇에 네트워크 및 정보 기술을 접목한 지능형 서비스 로봇의 새로운 개념으로서, 언제, 어디서나 나와 함께하며, 나에게 필요한 서비스를 제공하는 네트워크 기반 로봇이다. URC에서의 서비스는 물리적인 로봇뿐만 아니라 환경 내 내재된 임베디드 로봇 및 소프트웨어 로봇을 통해서 제공받을 수 있게 된다. 소프트웨어 로봇은 "유비쿼터스 네트워크 환경에서 언제 어디서나 상황에 맞는 정보와 서비스를 능동적으로 제공하는 새로운 개념의 지능형 소프트웨어"로 정의된다. 본 고에서는 이러한 소프트웨어 로봇의 개념과 이 개념을 지원하기 위한 시스템에 대해 논의한다.

URC는 기존 로봇에 네트워크 및 정보 기술을 접목한 지능형 서비스 로봇의 새로운 개념으로서, 언제, 어디서나 나와 함께 하며, 나에게 필요한 서비스를 제공하는 네트워크기반 로봇이다. URC 개념이 구현되기 위해서는 유비쿼터스 네트워크 또는 센서 네트워크, 고성능 로봇용 서버 등과 같은 하드웨어 인프라가 구축되어 있어야 하며, 이러한 인프라 상에서 구동되는 소프트웨어 인프라가 필요하다. 본 고에서는 URC의 소프트웨어 인프라의 구현에 요구되는 많은 기술 중 특히 상황인식 컴퓨팅 기술에 대해 논의하고 ETRI에서 개발중인 상황인식 미들웨어인 CAMUS에 대해 소개하고자 한다.

Early in 21st century, researches about intelligent service robot that provide various services for a human out of the industrial robot only has simple pattern repetition. It concentrates in the research regarding the URC(Ubiquitous Robotic Companion) robot which connects the network in the intelligent service. This paper proposes the robot system based on network to guide a way. The robot has made by lego brick and used ultrasonic sensor, rotation sensor and RFID tag to recognize external environment. Also, it includes a PDA to process the data between robot and server. The network server transmits information to robot controller by bluetooth and it controls the course movement and evasion of the robot. In this research, the robot system based on network to guide a way is easy to expand service and is able to process a data in real time due to data processing in the server as a part of intelligent robot. And it can reduce the cost to build a robot thank to use cheaper sensor equipment.

Recently, there are lots of concerning on ubiquitous environment of robots and URC (Ubiquitous Robotic Companion). In this paper, a practical ubiquitous interface system far controlling mobile robots in indoor environments was proposed. The interface system was designed as a manager-agent model including a PC manager, a mobile manager, and robot agents for being able to be accessed by any network. In the system, the PC manager has a 3D virtual environment and shows real images for a human-friendly interface, and share the computation load of the robot such as path planning and managing geographical information. It also contains Hybrid Format Manager(HFM) working for transforming the image, position, and control data and interchanging them between the robots and the managers. Mobile manager working in the minimized computing condition of handsets has a mobile interface environment displaying the real images and the position of the robot and being able to control the robots by pressing keys. Experimental results showed the proposed system was able to control robots rising wired and wireless LAN and mobile Internet.

In the ubiquitous environment, the real-time remote control and monitoring technology for intelligent robot creates service as a sharable and independent of time-location for various contents to get from a sensor or camera of the robot. In this paper, We propose 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. It has been carried out by implementing this technology into the target robot called ISSAC4 and proving its practical worth. We designed feasibly to control on remote site by web-browser. It guarantees a continuity of real-time image transferring by Client-Pull method.

The robotics industry, that is the major industry of the future and one of the new growth power, is actively studied around ETRI, that is the leading under state-run research institute of the advanced technique of U.S. and Japanese and knowledge economy part. And positive and negative and academic circles, the research institute, and the industrial circles communally pursue the intelligent service robot enterprise of a network-based called URC. This network-based intelligent robot does the RUPI2.0 platform and URC environment by the base. Therefore, a stability need to be enhanced in the through this near future when the research for the preexistence vulnerability analysis and security request is needed than the commercialized network-based intelligent robot in order to implement the network-based intelligent robot. Thus, in this paper, we propose the efficient authentication Framework which is suitable for the URC environment.

URC는 언제 어디서나 나와 함께 하며 나에게 필요한 서비스를 제공하는 로봇이라는 의미의 새로운 네트워크 기반의 지능형 서비스 로봇 패러다임이다. URC 환경에서 로봇은 사용자의 현재 상황을 이해한 뒤 적절한 정보와 서비스를 지능적이고 능동적으로 제공할 수 있어야 하며, 이를 위하여 상황 인식 시스템의 개발이 필요하다. 상황 인식시스템의 핵심 기능 중의 하나는 상황 인식 응용에서 이용 가능한 사용자의 주변 환경에 관한 정보를 표현하기 위한 형식적인 상황 정보 모델 및 이를 관리하고 이용하는 방법을 제공하는 데 있다. 본 고에서는 상황 인식 컴퓨팅의 기술 동향을 상황 정보 모델중심으로 소개하고, URC를 위한 상황 인식 미들웨어인 CAMUS의 상황 정보 모델 및 상황 정보 관리 모듈에 관하여 소개한다.

Speaker Recognition for the Intelligent Service Robot is implemented in this paper. For this purpose, we perform speaker recognition based on Gaussian Mixture Model(GMM) and use robot platform called WEVER, which is a Ubiquitous Robotic Companion(URC) intelligent service robot developed at Intelligent Robot Research Division in ETRI. The experimental results reveals that the approach presented in this paper yields a good identification (89.00%) performance within 2 meter distance.

URC robot offers necessary service anytime and anywhere by using a network to the robot, expanding the applicable service, keeping all the functions in itself, it undertakes functions for the causing problems through the network. URC software components are composed of HRI(Human Robot Interaction), robot action technology and others. We analyze the quality models based on ISO/IEC 9126, define URC components evaluation specification consists of 4 parts such as generic rule, instance rule, evaluation value and test method. And we define the quality process and test case design for URC, and show a testing and evaluation process for URC components.
