단일 센서 기반의 표적 탐지 문제에서 센서의 한계 요소에 의해 탐지 성능이 제한된다. 따라서, 최근 단일 센서 기반의 표적 탐지 성능을 향상시키기 위한 방안으로 각 센서의 강점을 효과적으로 융합하는 다중 센서 정보 융합 기반의 표적 탐지 기법에 대한 연구가 활발히 진행되고 있다. 센서 정보 융합을 위해서는 각 센서별 영상 획득, 각 영상의 기하학적 정합, 센서 정보 융합 기반의 표적 탐지 기술이 필요하며, 본 논문에서는 이에 대한 기술 및 개발 동향을 소개한다.

서비스 로봇의 지각과 행동에서의 신뢰성은 각 개별 요소기술의 완벽함으로부터 얻어지는 것이 아니라 비록 성능이 불완전한 요소기술들을 사용하더라도 각 요소기술들의 정보를 융합하고 능동적인 행위를 발생시키는 시스템적인 접근방식으로부터 얻어진다. 그러므로 본 연구에서는 자연스러운 HRI 구현을 위하여 "로봇인지 엔진"이라는 독창적인 통합 구조를 제안하였으며, 비동기/병렬 정보처리 구조, 다양한 지각정보들의 융합, 행위 결합을 위한 능동적인 지각정보 수집의 특징을 갖는다.

본 논문에서는 대학 캠퍼스 내 배달로봇 사용 시 환경적 특성에 의한 유해위험요인을 사전에 발굴하고 로봇의 출발지에서 목적지까지 발생할 수 있는 위험을 단계별로 추정·판단하여 위험을 감소에 대한 필요성에 관한 연구를 수행하였다. 캠퍼스 내 주행 구간별 유해위험요인을 파악 및 단계별 위험성 추정을 위하여 배달로봇을 사용하기 전 위험성을 사전에 확인할 수 있는 위험성평가의 필요성을 제시한다. 배달로봇 시장의 확대로 인한 사람과의 접촉 증가에 비하여 안전대책 연구가 미흡한 실정이며, 로봇의 기술적 진보와 사용자들의 정서적 수준에 뒤처지지 않는 적절한 안전대책을 마련해야 한다.

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.

In this paper, we propose the educational model for a convergence minor by fusing culinary arts with robot technology to develop coding ability for the students in the culinary arts major which is not originally related to software field. It is meaningful that the educational model follows the trend along the development of the fourth industrial revolution technology and has the function to make the students who are not in software major grow as software experts. However there are difficulties in designing the convergence minor because the culinary arts major is distant to the robot technology in the view of technology. To overcome this difficulty the convergence minor is designed to attract the interest for the students in culinary arts major by construct educational subjects systematically such as cooking, dessert making, barista working, autonomous serving and so on based on robots. Also the practices in which various robots are utilized are included in the convergence minor to develop actual coding ability. By comparison to the other models of convergence minors, the proposed model shows enhanced educational effects in 20% than the others.

The robot imitates humans and recognizes the external environment and judges the situation. The robot is a machine that operates autonomously. Robots are divided into manufacturing robots and service robots. Service robots are classified as professional service robots and personal service robots. Because of the intensified competition of productivity in manufacturing industries, rising safety issues, low birth rate and aging, the robots industry is emerging. Recently, the robot industry is a complex of advanced technology fields, and it is attracting attention as a new industry where innovation potential and growth potential are promising. IT, BT, and NT related elements are fused and implemented, and the ripple effect is very large. Due to changes in social structure and life patterns, social interest in life extension and health is increasing. There is much interest in the medical field. Now the artificial intelligence (AI) industry is growing rapidly. It is necessary to secure global competitiveness through strengthening cooperation between large and small companies. We must combine R&D investment capability and marketing capability, which are advantages of large corporations, and robotic technology. We need to establish a cooperative model and secure global competitiveness through M&A.

In this paper, we propose G-Robot framework implemented with the fusion technology called RITS(Robot Technology & Information Technology System) for robot control and remote monitoring using the mobile phone. In our implemented system, the mobile phone mounted on the robot controls the robot and sends the images to the mobile phone of the user. We can monitor surrounding area of the robot with mobile phone and control the movement of the robot by sending the data between mobile-phones. Also, if the predefined situation occurs to the robot, the mobile phone on the robot sends the data to the mobile-phone of the user. From the experimental result, we can conclude that it's possible to control the robot and monitor surrounding area of the robot in real time in the region where the 3G(Generation) communication is possible. In addition, we can control the robot using the bluetooth instead of the mobile phone communication if the robot is in visual range.
