Robovie-R2 [1], developed by ATR, is a 110cm high, 60kg weight, two wheel drive, human like robot. It has two arms with dynamic fingers. It also has a position sensitive detector sensor and two cameras as eyes on his head for recognizing his surrounding environment. Recent years, we have carried out a project to integrate new functions into Robovie-R2 so as to make it possible to be used in a dining room in healthcare center for helping serving meal for elderly. As a new function, we have developed software system for adaptive movement control of Robovie-R2 that is primary important since a robot that cannot autonomously control its movement would be a dangerous object to the people in dining room. We used the cameras on Robovie-R2's head to catch environment images, applied our original algorithm for recognizing obstacles such as furniture or people, so as to control Roboie-R2's movement. In this paper, we will focus our algorithm and its results.

A collaborative robot(Cobot) is one of the production systems presented in the 4th industrial revolution and are systems that can maximize efficiency by combining the exquisite hand skills of workers and the ability of simple repetitive tasks of robots. Also, research on the development of an efficient interface method between the worker and the robot is continuously progressing along with the solution to the safety problem arising from the sharing of the workspace. In this study, a method for controlling the robot by recognizing the worker's hand signal was presented to enhance the convenience and concentration of the worker, and the safety of the worker was secured by introducing the concept of a safety zone. Various technologies such as robot control, PLC, image processing, machine learning, and ROS were used to implement this. In addition, the roles and interface methods of the proposed technologies were defined and presented for using educational media. Students can build and adjust the educational media system by linking the introduced various technologies. Therefore, there is an excellent advantage in recognizing the necessity of the technology required in the field and inducing in-depth learning about it. In addition, presenting a problem and then seeking a way to solve it on their own can lead to self-directed learning. Through this, students can learn key technologies of the 4th industrial revolution and improve their ability to solve various problems.

Using robots in the programming classes may help to induce learners' interest and motivation. However, simple introduction of new media, such as robots, may cause to increase learners' interest level temporarily, but also may give cognitive overload and offense against learning motivation. We developed a robot programming course to induce intrinsic motivation and to reduce cognitive load for learners in the programming education. And then, we implemented the developed course in college programming classes and analysed the educational effects of robot programming learning on novice learners' flow level. We found that robot programming course was helpful in enhancing novice learners' flow level. Especially, the element of 'autotelic experience', which explains an intrinsic motivation, was higher than conventional programming course group. It means that the developed strategies for robot programming course provides positive effects on learners' intrinsic motivation.

The purpose of this study is to find out user preference on personification of the public service robot. Public service robot services in public places is increasing, which is expected to continue to increase. Proper anthropomorphism of robots has positive effect on user experience. On the other hand, when the level of likeness exceeds a certain point, it provokes strangeness and a sense of unease. Therefore, it is necessary to prepare standards for anthropomorphism required for public service robots. In order to find it, a survey and an in-depth interview were conducted. According to the analysis, people prefer verbal interaction with the robot, and the proper age for the voice is in their 20s and 30s. It is recommended that no biological signals appear on the robot and there is a need for personalized services. Through this research, it is expected that it will contribute to design of public service robots that enhance user experience.

This paper aims to design and implement a robot that will help teach children living habits and English conversation education in dual-income families using the open platform robot Q.bo one based on raspberry pi3 of a single board computer. The first function of life habit formation is to help children to wash their hands, to brush their teeth, homework and sleep regularly. The child is then photographed listening to the notification and acting so that the parent can identify and provide feedback. The second basic conversation education feature uses Google's DialogFlow to help children learn English naturally through simple English conversation through the robot. The two-functioning robot allows children from working families to feel secure by printing their parents' voices even when they are not at home. At the same time, it allows them to get into basic lifestyle, to have basic English conversation with robots, and to be interested in English early.

The purpose of this paper is aimed to derive suggestions for convergence technology for effective management of distance education by analyzing a long-term case. The experiment was designed with notebook, smartphone or tablet based robot controlled by a remote instructor and a learner, who have experience of distance learning including robot assisted learning. The tablet based robot has the display system of feedback to speakers. During five months, three types of experiments were conducted randomly and a participant was interviewed thoroughly. The result, like the previous research, demonstrates that the task performance of the learner in telepresence robot-assisted learning was better than that in the notebook, and smartphone based. However, it is believed to be necessary to adjust the system for eye-contact and voice transmission for the remote instructor. The instructor required an additional sight by supplementing an extra camera and automatic direction control to source of sound.

Interactive games allow users to obtain embodied experience using the bodies as controllers. The same is true in interactive media arts where users engage in active participation. In contrast to video games, physical body feedback is desired and such practice can be found in robotic arts. I suggest that interactive media arts and interactive games should share common foundations. In this context, I introduce and explain an interactive robotic art work implemented. This work is a musical instrument that employs a robot which travels sitting on two strings in response to audience positions. In results, the robot modulates the vibrations of the strings by causing the effective lengths of the strings changed. The robot uses an economic multi-cell proximity sensor in order to track the audience. In the interaction, phenomenological tension could take place in the performative narrative space. In this paper, I discuss this interactive robotic work in the context of interactive games with a few examples.

Developments and changes in digital environment based on computer technologies and internet networks enabled us interactive communication for planning and execution through the freedom of 'connection', 'sharing', and 'conversion'. The subject of this study, interactive commercial, might be the core of success based on creation which stems from communication design, revolution in design and technology, and conversion. Communication in modern economy is not optional, but essential. Furthermore, like evolution process up to Augmented Reality from developments of mobile communication technology, or concept in paradigm change, digital interactive commercial means the core of success, not a part of it. Therefore, in order to achieve success in the global competition structure, mobile communication design, revolution, and creation which produce added value shall be working as a base. In order to reach effective communication process performance of interactive commercial media, this study would like to propose building a media commercial system which is realized by human senses. Using this, standardized methods for interactive commercial which can be used together with augmented reality based on digital technology, and for using digital robot contents are available, along with methodology system of their use. In addition, the ultimate goal of this study aims to discover new factors through reorganization of precedent analysis and adaptation based on academic achievement and practical application. And thus, it wants to contribute to practical use of interactive commercial out of augmented reality-based communication in which technology, marketing, and design are integrated to be used in real sense.

본 논문은 감정 교류를 위한 목적으로 가상 캐릭터에서 사용되기 시작하여 현재 로봇에 이르기까지 그 이용 범위를 넓혀가고 있는 스토리텔링이 사용자 친밀성에 미치는 영향과 사용자가 어떻게 엔터테인먼트 로봇과 친밀성을 형성해나가는지, 또 친밀성 요소들은 다양한 스토리텔링에서 서로 어떤 관련성을 가지고 친밀성 형성에 영향을 주는지를 연구 목적으로 삼고 있다. 이를 위해 스토리텔링과 관련된 대화가 가능한 지능형 엔터테인먼트 로봇에 대한 연구를 우선적으로 알아보았으며, 이를 토대로 엔터테인먼트 로봇 중 하나인 애완용 로봇, 아이보(AIBO)가 지니고 있는 스토리텔링을 통해 사용자와 로봇 간 친밀성 형성 및 스토리텔링을 바탕으로 한 친밀성 요소간의 관련성을 알아보았다. 참가자 15명의 설문조사를 바탕으로 실시한 상관관계분석을 통해 사용자와 아이보(AIBO)가 정서적, 오락적, 행동적, 상호공유성에서 인지적, 사회적 친밀성보다 상대적으로 강한 친밀성을 형성하고 있다는 것과 Alexis K. Walker 와 Linda Thompson(1983)을 기본으로 대인관계 측면에서 친밀성에 대해 접근한 이경희(1998), 김혜정(2001), 김미라(2001), 이금남(2001), 송상홍(2004)의 선행 연구를 참조로 분류된 6가지 차원의 친밀성 구성 요소들은 스토리텔링의 형식에 따라 서로 다른 관계성을 형성하고 있다는 것으로 나타났다. 본 논문은 아이보(AIBO)에 쓰이는 스토리텔링이 친밀성 형성에 어떤 영향을 미치는지 또 스토리텔링의 차원에 따라 다르게 반응을 보이는 친밀성 요소들이 서로 어떤 관련성을 맺고 있는지를 살펴본 것에 의의를 둘 수 있다. 스토리텔링에 따라 관련성 정도를 달리하는 친밀성 요소들의 관계를 바탕으로 친밀성 형성에 유용한 스토리텔링의 방향을 제시하는데 의의가 있다.

We propose an intelligent interface algorithm using hand gesture recognition information based on artificial intelligence. This method is functionally an interface that recognizes various motions quickly and intelligently by using MediaPipe and artificial intelligence techniques such as KNN, LSTM, and CNN to track and recognize user hand gestures. To evaluate the performance of the proposed algorithm, it is applied to a self-made 2D top-view racing game and robot control. As a result of applying the algorithm, it was possible to control various movements of the virtual object in the game in detail and robustly. And the result of applying the algorithm to the robot control in the real world, it was possible to control movement, stop, left turn, and right turn. In addition, by controlling the main character of the game and the robot in the real world at the same time, the optimized motion was implemented as an intelligent interface for controlling the coexistence space of virtual and real world. The proposed algorithm enables sophisticated control according to natural and intuitive characteristics using the body and fine movement recognition of fingers, and has the advantage of being skilled in a short period of time, so it can be used as basic data for developing intelligent user interfaces.
