In this paper we suggest a model that the virtual robot based on artificial intelligence performs learning with compensation signals and compare the leaning speed of the virtual robot according to the compensation method after applying it to three type environments. As a result our model has showed that positive compensation is superior to hybrid one mixed positive and negative if there are enough time for learning in case of more or less complicated environment with the numerous foods, obstacles and robots. Otherwise hybrid method is better than positive one.

The current study explored if users' self-relevance of the comparison domain with creative AI robot in music composition affected their envy toward the robot, cognitive assessment toward the music and intention toward working with robot in future. This study conducted a 2 (degree of self-relevance: high(college students majoring in music) vs. low(those not majoring in music) × 2 (working type: robot-only vs. robot-human collaboration) between-subjects factorial design experiment. The findings revealed that those majoring in music did not feel envious of the robot as much as those not majoring in music. However, compared to those not majoring in music, those majoring in music evaluated the robot's creativity lower, had more negative attitude toward the music, showed less intention to use the music and work with the robots in future. No interaction between the degree of self-relevance and the working type was found.

Together with the development of ubiquitous computing technology and robot technology, intelligent type robots are being utilized in many areas and the range is expected to become wider and wider. Among many service robots, the educational robots are being diversely studied in the field with the concept of r-Learning. Presently, teaching assistant robots require a lot of HRI studies prior to their practical use in the very near future and are not sufficient yet. Especially, the reactions of students based of the styles of robots (e.g. serious robot, playful robot) are very important in producing robot contents but there has been no case study on them. Therefore, in this study, the appearance of the IROBI was changed to become a teaching assistant robot and was used to test and compare elementary school students' interest, achievement and concentration depending on the styles of robot (playful, serious). The results showed that the interest was high in the group that had studied with the playful robot. The achievement however, did not show significant relations with the style of robot and that the concentration was high in the group that had studied with the serious robot.

The effect of existing programming education has shown a limitation coming from its methodology. Thus, the researcher developed a Web-based robot programming support system and explored its possibility for overcoming problems in existing programming education and ultimately for enhancing creativity and problem-solving abilities of students. The developed system let students learn robot programming just with a PC or PDA connected to the Internet without additional hardware and software. Different types of robots linked with a server computer can be controlled by using different programming languages. It is possible to use Korean keywords for programming as well. Specially, this system was evaluated positively by the groups whose computer abilities are excellent and student of introductory or intermediate level programming course. Furthermore, the programming education that uses robot and the Hangul programming technology were given very positive reception by elementary school students.

This study intends to analyse the programming class with visual-basic, scratch and pico-cricket in elementary school. The study analyses cognitive domain by creativity tests and instructional process by student task engagement and the required factor of student's activity-nowadays, a lot of encouragement of learning use-. According to the result, The creativity of groups who use three teaching aid improves, but it hasn't any meaning. according to the student task engagement analysis by instructional process, According to the student task engagement analysis by instructional process, The concentration of group that uses pico-cricket and scratch falls down a little, but The concentration of group that uses visual-basic falls down remarkably. At last, according to the result of the required factor of student's activity, scratch and pico-cricket spend time discussing and programming, but visual-basic spends time correcting coding error. But pico-cricket spends much time preparing teaching aid or checking instrument, so this fact has to reflect when teacher plans his class. Through this fact, scratch and pico-cricket are better than visual basic as effective teaching aid when teacher teaches programming.

Autonomous mobile robot agents(AMRAs) are robots which perform a given task by the same distributed self-organizing rules. In this paper, we let them form an equi-distance circle for the task of cooperative behaviors. Here, we suggest an algorithm to perform the taqk and then utilize a fuzzy system to improve the algorithm. It is shown that various cooperative activities appear in the simulation and particularly chaotic behaviors also appear by increasing the robot speed. Moreover, we prove the characteristics of this chaotic behaviors by calculating Lyapunov exponent.

4차 산업으로 효율적인 진입을 위해 학교현장에서는 코딩교육을 하고 있다. PC앞에서 모니터에 의존하여 변화 없는 코딩 교육은 주입식 교육을 벗어나지 않을 뿐만 아니라 몰입도가 떨어지게 된다. 이를 해소 하고자 로봇을 만들고 프로그램 하여 성능평가를 하여 스스로 이해하고 집단 경기를 통해 재미와 학습을 효율적으로 코드를 익히기 위한 로봇 교구를 개발하고 실험을 통해 검증하고자 한다.

본 연구는 인간의 자아표현 욕구와 창조적 욕구로 인해 자신을 대체할 산물들을 끊임없이 만들어 내는 과정에서 중요하게 작용되는 자기노출라는 심리를 이용하여 아바타와 학습자의 얼굴을 합성하는 증강가상을 통하여 가상세계에서의 현실감을 부여함으로써 학습자의 몰입을 유도하여 그 교육적 효과를 증대하고자 하였다. 이를 실증하기 위하여 컴퓨터기반으로 컨텐츠를 개발한 후, 로봇 컨텐츠로써의 활용을 위해 컨버팅하고 자동 로딩을 통한 학습자의 사진을 아바타와 합성시켰다. 실험 결과 자기노출기반 컨텐츠의 효과는 모든 집단의 경우에서 학습에 대한 집중도에는 긍정적인 영향을 주었으며, 학업성취도에는 유의미하지는 않지만 긍정적 효과를 가지는 것으로 나타났다. 이는 교육용 로봇을 활용한 자기노출 개념 적용에 대하여 긍정적인 결과라고 보여지는데, 보다 유의미한 결과를 얻기 위해서는 단순히 사진을 찍어 로딩시키는 증강가상보다는 얼굴검출을 통한 실시간 증강가상과 같이 증강가상 효과의 증대가 필요하다고 하겠다.

Personal service robots, a type of social robot that has emerged with the aging population and technological advancements, are undergoing a transformation centered around technologies that can extend independent living for older adults in their homes. For older adults to accept and use social robot innovations in their daily lives on a long-term basis, it is crucial to have a deeper understanding of user perspectives, contexts, and emotions. This research aims to comprehensively understand older adults by utilizing a mixed-method approach that integrates quantitative and qualitative data. Specifically, we employ the Van Kaam phenomenological methodology to group conversations into nine categories based on emotional cues and conversation participants as key variables, using voice conversation records between older adults and social robots. We then personalize the conversations based on frequency and weight, allowing for user segmentation. Additionally, we conduct profiling analysis using demographic data and health indicators obtained from pre-survey questionnaires. Furthermore, based on the analysis of conversations, we perform K-means cluster analysis to classify older adults into three groups and examine their respective characteristics. The proposed model in this study is expected to contribute to the growth of businesses related to understanding users and deriving insights by providing a methodology for segmenting older adult s, which is essential for the future provision of social robots with caregiving functions in everyday life.
