Recently, the resource investigation has got much attention. The optimization of the resource investigation method and its automation are one of the most important keys for it. We propose the resource investigation emulating robot to overcome the conventional method; a numerical modeling. A nobel cable car robot system is developed. It minimizes the magnetic noise and comes true the gradient emulating of the field. This advanced system enables the optimization and automation of the resource investigation.

In order to solve problems such as a decrease in the agricultural population and an aging population, research on agricultural robots is being actively conducted for the purpose of automating various agricultural tasks. The harvesting process is the most labor-intensive process among farm work and this process consumes about 2-3 times more compared to other processes. Since the transport of agricultural crops requires the most labor costs and there is a risk of injury during the operation, automating the transport operation through an agricultural robot can improve safety and significantly improve productivity. Therefore, this paper proposes an agricultural robot that is optimized for farm worksites and capable of autonomous driving.

In building construction, the layout operation is performed to accurately construct the building components in their planned locations, and requires a high level of accuracy and precision. With increases in building size and a lack of skilled laborers, this work has seen an increasing demand for productivity and quality improvements through robot-based construction automation. In particular, the layout work for building structures has a higher need for automation. On this background, this study suggests a direction for the development of an automated layout system of building structures. 5 technical factors and 17 sub-factors were derived based on reviews of existing similar systems, and an evaluation of their importance was carried out through an expert survey. As a result, it was found that the most important factors were driving and marking systems for coping with poor driving and working conditions. In terms of sub-factors, control techniques to secure precision and technologies to automate the overall layout process showed high importance. These findings will contribute to the development of more practical and efficient automation systems.

3D 기피 현상에 따른 인력난은 이제 국내 산업계 전반에 걸친 커다란 문제가 되었으며, 특히 용접 및 절단 공정에서는 그 정도가 심각한 상황으로 숙련된 기술자 의 확보가 용이하지 않은 상황이다. 따라서 많은 기업에서는 제품의 품질향상과 대량 생산 능력을 갖추기 위해서 용접 및 절단 공정에서의 자동화를 추진하고 있으며, 로봇 을 이용한 방법이 각광을 받고있다. 그러나 이 경우에도 용접용 로봇과 절단용 로봇을 비교하여 보면, 일본의 경우, 절단용으로 출하되는 로봇의 수는 용접용 로봇의 1/70 - 1/100 수준이다. 국내의 경우 최근 들어 용접분야에서의 로봇의 이용은 활성화 되어 있는 편이지만, 절단의 경우는 적용예가 드문 실정이다. 절단용 로봇의 경우 로봇 이용분야가 가장 발달된 일본의 경우도 1988년부터 로봇을 절단용으로 이용하기 시작 하였으며, 그 이용분야도 레이저 절단과 워터젯트 절단에 치중되어 있다. 그러나 현실 적으로 국내 산업현장에는 주로 가스절단이 절단의 주류를 이루고 있는 실정으로, 이에 대한 로봇 응용 시스템의 개발이 시급하다. 대우중공업에서는 가스절단 로봇을 국삭기 Boom측판에 개선가공 공정에 적용하여, 가스절단 분야에의 로봇 적용이라는 가능성을 보여주었으며, 본고에서 그 내용을 소개하고자 한다.

애자 청소 작업은 애자의 절연 저하를 사전에 예방하기 위해 고소 고압의 환경에서 이루어지는 위험한 작업으로 정비작업의 능률과 정밀도가 떨어져 로봇을 이용한 활선 애자 청소 및 진단의 자동화가 요구되어진다. 이러한 요구에 따라 활선 애자 청소 로봇이 개발되고 있다. 본 논문에서는 개발된 애자 청소 로봇 제어를 위해 마스터 슬레이브 구조를 갖는 제어 시스템 구성을 제안하고, 실험을 통해 구현한 제어 시스템의 효용성을 보인다.

Recently, the RPA (Robotic Process Automation) solution, which has been spreading in Korea and overseas, allows users to easily automate their tasks with the application GUI (Graphic User Interface), and the number of Korean financial companies which Implemented for automating their business is increasing now. However, as the major supervisory regulations that financial institutions must comply with are based on the existing traditional SDLC (Software Development Life Cycle), it is not proper to be directly applied to RPA that automates end-user works on the level of user's system interface. Therefore, in this paper, we organized the important financial supervisory rules and control items that should be considered for RPA implementation, then surveyed 24 financial companies which have implemented RPA for checking how they applied them. Finally, we would like to present the necessity of revision of related compliance.

This article links the change in regional manufacturing employment in Korea after the financial crisis to the geography of technological and trade shocks. We conceptualize the trade shock as the rapid growth in Korean imports from and exports to China and ASEAN countries. We then measure the exposure to technological shocks as the degree to which regions are specialized in routine tasks, which are susceptible to automation technologies. Results show that local labor markets specialized in routine tasks experience significant falls in manufacturing employment. Regions whose industrial structure exposes them to rising import competition experience sharp drop in manufacturing employment. We also found that export plays a major role in explaining the growth of regional manufacturing employment.

3D printing technology is recognized as a core technology that will lead the next generation, and is a field that can have a large ripple effect if it innovates the existing construction production method. Therefore, this study deals with the development of a 3d printing system using an articulated robot for construction purposes. In this system, ABB robot was used to control the developed cement gun accurately. The system is composed of mixer to mix cementitious materials, pump to transfer the materials, abb robot to motion control and cement gun to extrude the materials to print required construction parts. Using the system developed in this study, a suitable mix ratio of cementitious materials was found and successively printed a 1m high structure that demonstrated possibility of printing structures using 3d printer. In the future, we plan to build a foundation for automated construction through research on construction methods and materials that can be continuously layered for the system.

Unmanned patrol robots are currently being developed for autonomous data survey in construction sites. As the amount of data acquired by robots increases, it is important to utilize proper metadata and system to manage data flow. In this study, we developed three materials, metadata design, robot system and web system, in the purpose of automating construction site data survey using unmanned patrol robots. The metadata was mainly designed to represent when and where raw data was acquired. To identify the location of data acquired, localization data from SLAM algorithm was converted to suit the construction drawings. The robot system and web system were developed to generate, store and parse the raw data and metadata automatically. The materials developed in this study was adopted to Boston Dynamics SPOT, a quadruped robot. Autonomous data survey of 360-picture and environment sensor was tested in two construction sites and the robot worked as intended. As a further study, development on the autonomous data survey to improve the convenience and productivity will be continued.
