음성인터페이스 기술이란 인간의 가장 자연스러운 의사소통 수단 중의 하나인 ‘말’을이용하여 기계와 인간과의 대화를 가능하게 하는 기술이다. 음성인터페이스 기술에 대한 연구는 1960년대부터 이루어져 왔으며 1990년대 후반부터 제한적으로 상용화되기 시작하였다. 아직까지는 기술적 한계에 의해서 간단한 명령어를 알아들을 수 있는 수준이며 응용 분야도 극히 제한되어 있으나 향후 텔레매틱스, 지능형로봇, 홈오토메이션등의 신성장동력 산업이 활성화됨에 따라 기존의 키보드, 마우스 등의 인터페이스 수단들이 충분히 만족스럽지 않은 환경으로 변화하면서, 음성인터페이스 기술은 매우 중요한 대안으로 떠오르고 있다. 본 고에서는 음성인터페이스 기술의 기본 원리 및 요소기술을 설명하고 관련 산업동향 및 응용분야, 그리고 향후 신성장동력 산업을 중심으로 한 발전 전망을 예측해본다.

In this paper, it was proposed a new technology to improve the performance of the remote control in virtual reality applications. The operator must know the information of surroundings of the robot, collision possibility of the equipment, and force feedback of the manipulator. The time delay problem occurs in the tele-operating and it causes vibration and expressive power of the manipulator owing to bidirectional force feedback. We presented a new control method to control of the teleoperating system based on serial bus. The reliability is evaluated by simulation.

This study proposes a new approach to implement smart factory based on robot monitoring system for a small and medium sized enterprise. The simulator includes the forward kinematics and inverse kinematics analyzes of articulated robots. We also modeled the dynamics of the robot and made it possible to simulate it in the program. We studied the interface between the user and the monitoring programming system using the GUI environment of Windows OS, and it is configured to select the appropriate trajectory planning and control method. The reliability of simulator is illustrated by simulation test.

The use of robots in automated factories requires accurate bin-picking to ensure that objects are correctly identified and selected. In the case of atypical objects with multiple reflections from their surfaces, this is a challenging task. In this paper, we developed a random 3D bin picking system by integrating the low-cost vision system with the robotics system. The vision system identifies the position and posture of candidate parts, then the robot system validates if one of the candidate parts is pickable; if a part is identified as pickable, then the robot will pick up this part and place it accurately in the right location.

What is the socio-cultural meaning of the 1980s' Korean robot animations? What is the periodical backgrounds making this meaning? This study has attempted to lay the foundation stone of the answer for the questions. To do that, this study selected Roboteu King(Yeong-rang Bae, 1980) and Super Titan 15(Seung-cheol Park, 1983) as the objects of the textual analysis. To grasp the periodical identity, it has examined the cold war ideology that has been the basis of the political and economic environments of Korea. Findings are as follows. Korea was vulnerable to general environments after the Korean War; accordingly, Korea took the-dependence-on-the-US strategy in terms of various aspects including national security, scientific technology, and industry economy. This kind of socio-cutural condition was represented through the narratives of the early 1980s' Korean robot animations. Their narratives including the advance of plots, the roles of Korean protagonists, the technological gap between the planets and earth, and so forth were quite dependent on extraterrestrials and contained anticommunist ideology.

The use of robots is no longer limited to the field of industrial robots and is now expanding into the fields of service and medical robots. In this light, a trajectory generation method that can respond instantaneously to the external environment is strongly required. Toward this end, this study proposes a method that enables a robot to change its trajectory in real-time using a convolution operation. The proposed method generates a trajectory in real time and satisfies the physical limits of the robot system such as acceleration and velocity limit. Moreover, a new way to improve the previous method (11), which generates inefficient trajectories in some cases owing to the characteristics of the trapezoidal shape of trajectories, is proposed by introducing a triangle shape. The validity and effectiveness of the proposed method is shown through a numerical simulation and a comparison with the previous convolution method.

The exoskeleton robot is a technology developed to be used in various fields such as military, industry and medical treatment. The exoskeleton robot works by sensing the movement of the wearer. By recognizing the wearer's daily activities, the exoskeleton robot can assist the wearer quickly and efficiently utilize the system. In this study, LDA, QDA, and kNN are used to classify gait types through kinetic data obtained from subjects. Walking was selected from general walking and stair walking which are mainly performed in daily life. Seven IMUs sensors were attached to the subject at the predetermined positions to measure kinematic factors. As a result, LDA was classified as 78.42%, QDA as 86.16%, and kNN as 87.10% ~ 94.49% according to the value of k.

This paper analyzed 'Education with Robots' of the Practical Arts unit among the six textbooks developed under the 2015 revised curriculum, and provided implications for selection of textbooks, researching curriculum, and developing the next textbook. As a result of analyzing the prior study, it was found that the inquiry analysis was insufficient in the elementary school 'Education with Robots' unit. On the contrary, in the middle and high school textbooks research were sufficient. Therefore, we analyzed the contents of the textbook using the Romey analysis method, judging that our children who will live in the era of the Fourth Industrial Revolution need an inquiry type textbook. As a result of analyzing textbooks, there was no ideal textbook with an inquisitive disposition in all analysis elements, and in all textbooks, the analysis element with the lowest inquiry disposition was the text, and the highest analysis element was activity.

This study exploits the robot system which is necessary in gene study, bio-technology industry. As well, it can achieve the job of DNA chip manufacturing whose use rate has been increased recently. The robot consists of DNA spotting device for spotting DNA on the silylated slide and well plate, bed for fixing well-plate, washing & drying device of washing and drying the pin part of DNA spotting device, distillation-water vessel, and discharge vessel of wash water. We made the term of sticking DNA to the pin on well plate to be 15 seconds. The spot size of DNA was set to be 0.28 mm on the average by bringing the slide into contact with pin for 1 second. At this rate, if DNA is spotted in the minimum space possible of about 0.32mm, it can stick about 8,100 DNA spots on the well plate. Analyzing the procedure: Movement starts. Pin washes, dries, and smears DNA on the well plate. Spots DNA onto 12 chips takes 2 minutes and 50 seconds.
