In this paper, we implemented an intelligent home service robot system which alerts users to danger by wireless internet platforms for interoperability(WIPI) of a cellular phone. This paper discusses the three parts of the system: robot, middleware and mobile system. First, the robot consists of a gas sensor, a fire detector, ultrasonic sensors, motors, a camera and a Bluetooth module. The robot perceives various danger circumstances. Second, the middleware connects the robot and the mobile system. It monitors the robot and sends emergency notification SMS message to the user's cellular phone if in danger. Third, the mobile system sends commands which control the robot using TCP/IP protocol. The proposed scheme is to control the sensors of the robot part through Atmega 128 processor, and the robot and middleware parts will be installed in the household, and will be controled by mobile part from the outside.

Recently, home network system is providing more various services as home robot applied. A home robot not only basically controls home device but also services prevention of crimes, prevention of disasters through home monitoring and various entertainments while it navigates the autonomously based home network system. However, for the existing home robot to it is not easy to install all functions because the size of robot device becomes larger and the management of contents and applications executed becomes uneasy and has difficulties in adding new functions. Moreover many improvements are necessary for functioning of robot's location awareness. In this paper, we propose a more improved home robot system which uses resources of the robot efficiently as it divides the complicated operation of the robot among external digital device and adds new functions easily and recognizes the location of the robot by RFID.

현재 몇 가지의 제품으로 시장에 출시되어 가정에 조금씩 보급되기 시작한 홈 서비스 로봇은 각각의 제품이 청소, 도난방지 감시, 애완용 등의 특정한 기능을 가지고 가정에서 쉽게 사용 할 수 있도록 날로 발전을 더해가고 있다. 그러나 이러한 현재의 로봇들은 대부분 탑재된 기능과 인공지능이 결합하여 스스로 동작하는 자동화 로봇의 특징만을 지니고 있을 뿐이다. 홈 서비스 로봇의 정의에 충실한 사용자와의 커뮤니케이션의 기능은 거의 전무 하며, UI를 이용한 사용자 인터페이스의 환경에 의존할 뿐이다. 따라서 본 논문에서는 현재 홈서비스의 로봇의 한계성을 극복하고, 저렴하며 활용성이 높은 새로운 홈서비스 로봇의 모델을 제시한다.

This thesis aims to realize an intelligent home service robot that alerts the user to dangerous situations such as fires and gas leaks by utilizing wireless internet platforms in a cellular phone. The intelligent home service robot is composed of the following parts: The robot part consists of a gas sensor, a fire detector, a smoke sensor, ultrasonic sensors, motors, a camera and a Blue-tooth module and perceives various danger circumstances; The middleware part connects the robot part with the mobile part through the middleware applications, monitors the robot and notifies an emergency situation using SMS modules; The mobile part communicates with the middleware using TCP/IP protocol and controls the robot through various commands; The proposed scheme is to control the sensors of the robot part through and Atmega128 processor, and the mobile part was developed based on the WIPI platform. The robot and middleware parts will be installed in the household, and will be controled by mobile part from the outside.

A specialized anthropomorphic robot manipulator which can be attached to the housemaid robot McBot II, is developed In this paper. This built-in type manipulator consists of both arms with 3 DOF (Degree of Freedom) each and both hands with 3 DOF each. The robotic arm is optimally designed to satisfy both the minimum mechanical size and the maximum workspace. Minimum mass and length are required for the built-in cooperated-arms system. But that makes the workspace so small. This paper proposes optimal design method to overcome the problem by using neck joint to move the arms horizontally forward/backward and waist joint to move them vertically up/down. The robotic hand, which has two fingers and a thumb, is also optimally designed in task-based concept. Finally, the good performance of the developed manipulator is confirmed through live test of tasks.

현재 아파트를 중심으로 가정에 보급되기 시작한 홈 네트워크 시스템은 단순 홈 서버를 기반으로 가정 내 다양한 기기들을 연결하고 외부 인터넷 망과 연동하는 등 여러 가지 시도가 있으나 아직까지 단편적인 서비스를 제공하는 수준에서 크게 벗어나지 못하고 있다. 본 논문은 이러한 현 홈 네트워크 시장 상황에서 다양하고 실질적인 응용을 실제로 구현하고 사용자와 상호작용하기 위해 인공지능을 갖춘 서비스 로봇을 활용함으로써 홈 네트워크 시장을 활성화하기 위한 방안을 제시한다.

가까운 미래의 가정에서는 여러 기능을 가진 로봇이 등장하여 사람과 늘기도 하고 집도 지키는 방범활동도 수행하는 등 공상과학영화 속의 일들이 현실로 다가올 것이다. 핵가족화와 맞벌이 부부의 증가로 어린이들이 혼자 집에 있는 시간이 많아졌으며 이에 불안을 느낀 학부모들은 자녀들을 학원 등의 사설교육기관에 맡겨 사교육비의 증가가 사회문제로 대두되고 있다. 그러나 가정에서 부모와 떨어져 있는 동안의 어린이의 생활을 보여주거나 학습을 도와주는 로봇이 가정에 있다면 부모들은 안심하고 직장생활에 더욱 충실하게 될 것이며 사교육비의 감소현상에도 기여할 수 있을 것이다. 이에 본 논문에서는 가정용 로봇이 서비스하게 될 기능들 중에 초등학교 어린이의 학습을 도울 수 있는 기능에 초점을 맞추어 설문을 통해 요구를 조사하고 분석하였으며 홈 로봇과 사용자간의 메뉴를 크게 일정관리, 학습관리, 학습, 메신저 등의 카테고리로 분류하여 각 항목별로 세부 서비스 내용을 체계화하였다. 로봇을 활용한 학습 도우미 시스템의 설계는 앞으로 무한한 부가가치를 창조하게 될 로봇산업의 발달과 새로운 형태의 교육을 가능하게 하는데 큰 기여를 하게 될 것이다.

PSTN (public switched telephone network) provides voice communication service, whereas IP network provides data oriented service, and we can use IP network for multimedia transport service (e.g. voice over IP service) with economic price. In this paper, we propose RoIP (robot on IP) service scenario, signaling call flow, and implementation to provide home automation and monitoring service for remote site users. In our scheme, we used a extended SIP (session initiation protocol) for signaling protocol between remote site users and home robots. For our bearer transport control, we implemented H.263 video codec over RTP (real-time transport protocol) and additionally DTMF (dual tone multi-frequency) transport for robot actuator control. We implemented our scheme on home robots and experimented with KTF operator network, and it shows good communication quality (average MOS = 9.15) and flexible robot controls.
