Generally inpipe robot needs force above standing for contacting robot to pipe. If the environment of the pipe-inside does not change, there is not a problem. But if the pipe radius change, or occur the obstacle which it does not intend, problem gets. So it uses a different system and must know an environment change, and changing the shape or a form of the robot. The research uses the flexible leg and is the robot which is adapted to the environment change of the pipe. The advantage of this robot is possible to move when it does not need to recognize a change of environment of pipe. Leg is bend with one direction. When it moves part that there are legs effect of leg direction the robot is moved with only one direction. If friction between legs and pipe is sufficient, not only verticality pipe moving, but also curved pipe moving. Also the obstacle of the pipe inside occurs and the diameter of the pipe inside changes, this robot can move if it does not use another system or device.

The robot for narrow space is used in searching, investigating or cleaning. Up to now variety of researches on in-pipe robots have been introduced. However it is still hard to overcome vertical or curved passage. In most cases of narrow space robots are able to travel just aimed diameter which was selected when those are developed. Also, a large percentage of robots are not able to detect the configuration of pipe or circumstance. In this paper we present a robot called PAROYSⅡ for narrow space with vertical and curved passage. This proposed robot is not affected at all to variance of pipes, vertical or horizontal passages, curved pipes, projecting parts and parallel planes. In addition to that, it will perceive the internal configuration of pipe and terrain, which will be not only available to control navigating scheme by itself, but also mappable about the passage which the robot traveled. Core points in the design and structure are introduced and preliminary verification is given.

본 연구에서는 자율사물 중 도서관에 적용가능한 로봇과 드론, 자율주행을 중심으로 전반적인 내용을 살펴보고 이를 기반으로 향후 도서관에 도입 및 적용할 수 있는 방안을 제안하였다. 연구 결과, 관내의 경우 로봇과 드론을 활용하여 장서점검, 장서운반, 장서배열, 장서분류에서부터 도서위치안내, 도서추천, 대출/반납, 도서관 전반적인 안내, 참고정보서비스 등까지 적용할 수 있다. 관외의 경우 로봇, 드론, 자율주행 자동차를 활용해 도서배송서비스, 도서반납서비스, 무인이동도서관 등에 활용할 수 있을 것으로 보인다. 본 연구는 도서관의 자율사물 도입 및 적용을 위한 기초연구로써 향후 체계적인 도입을 위한 인식조사, 적용모델 개발 등의 후속 연구가 진행되어야 한다.

An endoscope is usually inserted into the human body for the inspection of the gullet, stomach, and large intestine (colon) and this may cause discomfort to patients and damage to tissues during diagnostic or therapeutic procedures. This situation necessitates a self-propelling endoscope. There are many kinds of mechanism to move in a rigid pipe. However, these methods are difficult to apply directly to the endoscope. The main reason is that human intestine cannot be considered as a uniform, straight, and rigid pipe. This paper proposes a flexible loop wheel mechanism, which is adaptable to the human intestine. This mechanism is designed and fabricated by a simple modeling, and tested by an experiment. Finally, the actuator is inserted into the pig colon.
