모바일 서비스와 교육 보조 로봇이 발달함에 따라, 로봇은 우리의 삶의 일부가 되었고 교육 보조 로봇은 선생님을 보조해 학생들의 교육과 학습에 참여하고 있다. 본 논문은 교육 보조 로봇의 자율성의 정도를 표시하는 자율성 지수를 측정하기 위한 방법을 규정한다. 자율성은 사람의 개입 없이 현재 상태 및 센서 값을 기반으로 주어진 작업을 수행하는 능력이다. 교육 보조 로봇의 자율성 지수는 작업 수준과 사람의 개입 수준으로 구성되며 1단계에서부터 10단계로 정의한다. 제안 방식은 지능형로봇표준포럼(KOROS) 표준으로 채택이 되었으며 해당 표준은 자율적으로 학생들을 지도하는데 활용이 가능하다. 향후 교육 보조 로봇을 활용한 교육 서비스에 큰 혜택을 가져올 것으로 예상하며 그 활용 분야 역시 교육 발전에 크게 이바지할거라 기대한다.

Expectation for improvement of creativity and problem-solving capability has increased the creative robotics classes in the form of after-school activity in more than half of total elementary schools. While Ministry of Education, Science and Technology has promoted 'Green IT Guidelines' as a part of 'Eco-friendly Green School Development Project', the Green issues have not been considered enough in those creative robotics classes. In this paper, we would like to address the Green issues, especially in the r-Learning services based on UCR (User Created Robots). First, trend of green IT education, r-Learning services and UCR are reviewed. And the current status of eco-related operations and teachers' perception in the robotics classes of elementary schools is investigated. Examples of Green UCR are also searched and green programs based on the three kinds of UCR, UC-TR, UC-AR, UC-CR, are explored. Finally, we propose action plans to promote the UCR-based r-Learning service reflecting green issues.

로봇을 활용한 프로그래밍 교육은 학생들의 몰입도를 높일 수 있는 방법으로 각광받고 있다. 로봇은 메커니즘 요소와 프로그램 요소가 결합된 형태라고 볼 수 있는데 방과후 수업에서 이루어지고 있는 형태를 보면 로봇의 메커니즘 요소에 대한 교육이 대부분이다. 그에 비하여 로봇 프로그래밍에 대한 교육은 이제 시작하는 단계로 볼 수 있으며 센서들과 연결하여 프로그래밍하는 것에 대하여 학생들은 어려움을 느끼고 있다. 따라서 본 논문에서는 센서부터 동작 기기까지의 로봇 프로그램 요소들의 관계를 설정하고 교육에 적용하였다. 적용 결과에 대한 평가 설문에서 학생들은 관계를 이해한 후 로봇 프로그래밍에 대하여 보다 잘 이해할 수 있다고 응답하였다.

Objectives: The purpose of this study was to investigate the factors affecting robot utilization in the education of pre-dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygiene students studying in the Daejeon, Chungcheong, and Jeolla provinces during the period March 1-31, 2017. Results: Future oral health education media had high selection of 'movies,' 'video,' '3D printer,' 'robot,' and 'drone' In general education and oral health education, robots were appropriate as educators, assistant teachers, and media. This group had high levels of interest, experience, attitude, and learning scope of robots. Robot utilization education showed a significant positive correlation with the 'interest,' 'experience,' 'attitude,' and 'learning' subfactors (p<0.01). Factors influencing robot utilization education were the relationships among actual experience of robot, learning of robot production, social influence of robot, emotional exchange with robot, and the predictive power was 25.5% (p<0.05). Conclusions: Oral health education curricula using robots should be developed considering the emotional exchange and social influence between educator and learner.

This paper presents a path planning problem for multi-robot system in the environment with dynamic obstacles. In order to guide the robots move along a collision-free path efficiently and reach the goal position quickly, a navigation method based on fuzzy logic controllers has been developed by using proximity sensors. There are two kinds of fuzzy controllers developed in this work, one is used for obstacle avoidance and the other is used for orientation to the target. Both static and dynamic obstacles are included in the environment and the dynamic obstacles are defined with no type of restriction of direction and velocity. Here, the environment is unknown for all the robots and the robots should detect the surrounding information only by the sensors installed on their bodies. The simulation results show that the proposed method has a positive effectiveness for the path planning problem.

In this paper we present the guideline to evaluate the easiness of using personal robots and their learning abilities based on the analysis of their built-in commands, user interfaces, and intelligences. Recently, we are breathing with robots that can be able to do lots of roles. cleaning, security, pets and education in real life. They can be classified as home robots, guide robots, service robots, robot pets, and so on. There are, however, no standards to evaluate their ability, so it is not easy to select an appropriate robot when a user wants to buy it. Thus, we present, as a guideline that can be a standard for the evaluation of the personal robots, the standards by means of analyzing existing personal robots and results of the recent research works. We will, also, describe how to apply the evaluation method th the personal robot.

How to promote students interest is very important in undergraduate engineering education. One of the techniques for achieving this is select appropriate projects and to integrated them with regular courses. In this paper, a voice recognition system for autonomous robots is proposed as a project to educate students about microprocessors efficiently. The proposed system consists of a microprocessor and a voice recognition processor that can recognize a limited unmber of voice patterns. The commands of autono-mous robots are classified and are organized such that one voice recognition processor can distinguish robot commands under each directory. Thus. the proposed system can distinguish more voice commands than one voice recognition processor can. A voice com-mand systems for three autonomous robots is implemented with a microprocessor Inter 80CI196KC and a voice recognition processor HM2007. The advantages in integrating this system with regular courses are also described.

This paper proposes an intelligent method for the optimal load distribution of two cooperating robots(TCRs) using fuzzy logic. The proposed scheme requires the knowledge of the robots' dynamics, which in turn depend upon the characteristics of large flat panel displays(LFPDs) carried by the TCRs. However, the dynamic properties of the LFPD are not known exactly, so that the dynamics of the robots, and hence the required joint torque, must be calculated for nominal set of the LFPD characteristics. The force of the TCRs is an important factor in carrying the LFPD. It is divided into external force and internal force. In general , the effects of the internal force of the TCRs are not considered in performing the load distribution in terms of optimal time, but they are essential in optimal trajectory planning: if they are not taken into consideration, the optimal scheme is no longer fitting. To alleviate this deficiency, we present an algorithm for finding the internal-force factors for the TCRs in terms of optimal time. The effectiveness of the proposed system is demonstrated by computer simulations using two three-joint planner robot manipulators.
