로봇 카메라를 이해하고 제작하기 위해서는 로봇 카메라의 회전이나 공간 이동에 의해 발생하는 인접 이미지 간의 영상 왜곡에 대한 이해가 우선적으로 진행되어야 한다. 본 논문에서는 영상 왜곡에 관한 수학적인 해석과 이 수학적인 해석을 렌즈 시스템과 연결하여 일반화하고 결국 로봇 카메라에서 일어나는 영상의 왜곡인 parallax 오차에 대한 유용한 해석 방정식을 얻었다. 이 방정식으로부터 로봇 카메라의 구조설계가 가능하게 되고 한 예로서 기존 구글의 ART 로봇 카메라에 대한 분석과 이해가 확장될 수 있었다.

A group of universities have come together with the aim of designing and developing Small Aperture Robotic Telescopes (SmART) for use by students to observe variable stars and transient follow-ups. The group is deliberating on the components of the robotic system; e.g. the telescope, the mount, the back-end camera, control software, and their integration keeping in mind the scientific objectives. The prototype might then be replicated by all the participating universities to provide round the clock observations from sites spread evenly in longitude across the globe. Progress made so far is reported in this paper.

체감형 게임에서는 사용자의 몸 자체가 인터페이스로써 컨트롤러의 기능을 가지며 사용자는 자신의 행동의 결과를 체화된(embodied) 경험으로써 피드백 받는다. 이는 관객이 적극적으로 참여하는 상호작용 미디어 아트 설치미술의 경우와 같다. 컴퓨터 게임의 대부분을 차지하는 비디오 게임과는 차별적으로 실물의 움직임으로 피드백 되는 게임이 고려될 수 있으며 그 기초는 로보틱 아트에서 찾을 수 있다. 본 논문은 게임과 상호작용 미디어 아트의 접점을 체감형 게임으로 전제하여 하나의 상호작용 로봇 설치물 사례를 제시하고 실험하며 분석한다. 본 설치물은 관객의 위치나 움직임에 의하여 운동하고, 로봇의 운동에 따라 현의 유효길이가 조절됨으로써 소리에 변화를 주는 하나의 학기이다. 로봇은 다중 셀 거리 센서를 이용하여 관객을 추적하고 관객은 일정한 거리를 두고 악기와 상호작용하므로 악기와 관객 간에는 관계적 긴장이 자리할 공연적 내러티브 공간이 형성된다. 본 논문에서는 이러한 상호작용 로봇 설치미술이 상호작용에 기초한 엔터테인먼트적 요소를 지닌 체감형 게임의 원형으로 제시될 수 있음을 몇 가지 사례를 들어 토론한다.

Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines. Since 2009, basic skills training courses have been organized by the Robotic Assisted Microsurgical and Endoscopic Society. These basic courses are performed on training models in five levels of increasing complexity. This paper reviews the current state of the art in robotically asisted microsurgical training.

Since the first laparoscopic gastrectomy for cancer was reported in 1994, minimally invasive surgery is enjoying its wide acceptance. Numerous procedures of this approach have developed, and many patients have benefited from its effectiveness, which has been recently demonstrated for early gastric cancer. However, since laparoscopic surgery is not exempt from some limitations, the robotic surgery system was introduced as a solution by the late 1990's. Many experienced surgeons have embraced this new emerging method that provides undoubted technical and minimally invasive advantages. To date, several studies have concentrated to this new system, and have compared it with open and laparoscopic approach. Most of them have reported satisfactory results concerning the post-operative short-term outcomes, but almost all believe that the role of robotic gastrectomy is still out of focus, especially because long-term outcomes that can prove robotic oncologic equivalency are lacking, and operative costs and time are higher in comparison to the open and laparoscopic ones. This article is a review about the current status of robotic surgery for the treatment of gastric cancer, especially, focusing on the technical aspects, comparisons to other approaches and future prospects.

Automation and robotic technology (ART) has been successfully applied in the manufacturing and allied industries to achieve on-time delivery of quality products at increasingly reduced costs. Meeting time, quality and cost targets still remains a big challenge in the global construction industry with prevalence of time and cost overruns. Application of ART in the construction industry could contribute to significant improvement in the efficient and effective delivery of projects to meet and exceed client expectations. However, the uptake of ART is still low in the construction industry. This study investigates the various ways in which ART could be applied to improve construction project delivery, potential areas of applications, and constraints to the uptake of the technology in the construction industry. Recommendations are made for improving the uptake of ART in the construction industry.

In this article art performing applications of industrial dual-arm robots are introduced. It was real collaboration among robot researchers and artist. Artist designed the performance to use dual-arm robot. Robot researchers collaborated with artist by providing robotic constraints and configuring robot motion. Two art performances were configured with two industrial dual-arm robots. In both performance robots carry objects to be used as moving screens. Both performances rely on the high power and high precision of robots. In addition human-like appearance make those performances be familiar to public.

Robotic techniques can be one of the promised solutions to address the prostate cancer which is one of the most important public health problems in medical fields. Despite several past and on-going dedicated researches, the systematic techniques and completed theories have not been established well. Therefore we review the state-of-the-art literature on the applications of engineering technologies with particular focus on diagnosis and treatment of prostate cancer. The current status of the elastography and systematic DRE are presented as novel diagnostic tools, and an overview of the applied technologies to address the limits of the treatment (radical prostectomy and brachytherapy) is reviewed.

The objective of this paper is to survey the state of the art of multisensor data fusion in intelligent robot systems. The variety of approaches to the problem of multisensor fusion ranging from general frameworks to robotic applications is surveyed. We have classified them into three categories : sensor modeling, fusional methods, and robotic applications. Also we present research trend and future direction of multisensor fusion.
