본 논문은 진공을 이용한 흡착방식과 바퀴형 이동방식을 이용하고 환경 탐지용 센서를 부착한 벽면 이동형 로봇의 물리적 해석을 통한 이동 성능 개선에 관한 연구로서, 대형 구조물의 안전 검사 및 위험한 시설물의 보수 작업 등을 보조하기 위한 목적이 있다. 로봇의 무게에 따른 중력을 견딜 수 있는 강력한 진공흡착방식과 고성능 모터제어에 의한 바퀴 이동방식을 혼합하고 효율적으로 평형을 유지 또는 제어하기 위하여 로봇에 미치는 다양한 힘과 모멘트를 분석하고 수식화 하였으며 기존의 수직이동 속도를 개선하기 위한 로봇의 물리적 변수를 추출하여 변수와 이동력간의 관계를 고찰하였다.

The robot has a smart function with the development of mobile devices and provides safety and convenience to our lives. In this paper, we study multiple robotcar system based on mobile that can be controlled by remote control. Robotcar with arduino can be controlled from server, but it also designed to be controlled by mobile devices as controller's necessary. Besides, it have feature that many robotcars can be controlled at the same time by using several mobile devices which select each robotcar.

실내형 자율 주행 로봇에서의 가장 중요한 기술력은 IGS(indoor GPS System)라 할 수 있다. 재난로봇이나 정찰로봇, 경계로봇등 새로운 로봇의 영역이 늘어남에 따라 실내에서 로봇을 안전하게 구동시키는 연구가 활발히 진행되고 있다. 기존 GPS를 사용할 수 없는 실내에서, LED 조명으로 통신이 가능한 가시광통신은 실내위치 정보를 정밀히 파악하기에 적합하다. 이에 가시광통신을 이용하여 LED 조명별 기준위치를 파악하는 서로 다른 16진수의 데이터를 전송하고, 그 위치를 파악하여 LED 조명의 위치를 식별할 수 있음을 확인한다. 이러한 실험결과를 통하여 가시광통신을 이용해 실내형 자율 주행 로봇의 실내 위치 추정 시스템을 제안한다.

In this paper, we analyzed the units related to robot education in the Practical Arts textbooks according to the 2015 revised curriculum. As a result, all textbooks had a common system of introduction, development, and organization, and all of them showed a similar flow. Learning objectives were presented in all textbooks, but no affective goals were presented except cognitive and functional goals. The contents of robot learning suggest the meaning and type of robots, the structure and sensors of robots, and the activities of making robots, but the contents of robot ethics, the production and activities of various robot works, and the use of robots in the problem solving process are not presented. The assembly robot and the infrared sensor are used in common, and it consists of presenting robot production and control training materials in experience activities and arranging units through evaluation, and the A, C, and F textbooks also provide the unit auxiliary data. In the future, it will be necessary to include the contents of robot ethics education centered on the design/manufacturer and user-oriented robot ethics such as the recognition of the limits of robots, the principles of using robots correctly, safety education, personal information and privacy protection.

This study is a review study attempted to analyze the current situation of surgical robots based on previous research on surgical robots in the era of the 4th revolution, and to forecast the future direction of surgical robots. Surgical robots have made full progress since the launch of the da Vinci and the surgical robot is playing a role of supporting the surgeries of the surgeons or the master-slave method reflecting the intention of the surgeons. Recently, technologies are being developed to combine artificial intelligence and big data with surgical robots, and to commercialize a universal platform rather than a platform dedicated to surgery. Moreover, technologies for automating surgical robots are being developed by generating 3D image data based on diagnostic image data, providing real-time images, and integrating image data into one system. For the development of surgical robots, cooperation with clinicians and engineers, safety management of surgical robot, and institutional support for the use of surgical robots will be required.

본 논문에서는 동적환경의 잠재적 위험 정의와 안전한 전역경로 계획 알고리즘을 제안 하였다. 대부분의 전역경로계획 연구는 시간과 거리의 비용을 최적화 시키는데 집중하고 있다. 하지만 동적환경으로 우리 주변에 많은 위험요소가 작용하고 있다. 본 논문에서 안전한 자율주행을 위한 경로계획방법으로 위험지역에 의해 정의 된 반발력과 S*알고리즘을 이용하여 안전하고 빠른 최적의 경로계획을 이루었다.

New infectious diseases such as MERS have been in need of many measures such as initial discovery, isolation, and crisis response. In addition, the culture of hospitals is changing, such as the general public 's visiting and Nursing Care Integration Services. However, as the qualifications and regulations of medical personnel in hospitals become rigid, overseas such as linens, wastes movements are replacing possible works with robots. we have developed a hospital logistics robot that can carry out various goods delivery within a hospital, and can move various kinds of objects safely to a desired location. In this thesis, we have studied a hospital logistics robot that can carry out various kinds of goods delivery within the hospital, and can move various kinds of objects such as waste, and linen safely to a desired location. The movement of a robot in a hospital may cause a collision between a person and an object, so that the collision must be prevented. In order to prevent collision, it is necessary to recognize whether or not an object exists in the movement path of the robot. And if there is an object, it should recognize whether it moves or not. In order to recognize human beings and objects, we recognize the person with face/body recognition technology and generate the context awareness of the object using 3D Vision image segmentation technology. We use the generated information to create a map that considers objects and person in the robot moving range. Thus, the robot can be operated safely and efficiently.
