목 아래로 전신마비가 되어 간병인 없이는 일상적인 생활이 불편한 와병 환자들을 위하여 뇌파(EEG) 및 목의 근전도(EMG)와 같은 생체신호 기반의 인터페이스를 제안하였다. 이를 이용하여 환자의 이상 상태를 보호자에게 알릴 수 있고 환자의 제한적인 움직임이나 집중하는 것만으로도 간단한 서비스 등을 직접 로봇에게 명령을 내릴 수 있도록 구현하였다.

In this paper, a robot automation technology for chemical tank lorry unloading is presented. Handling chemical coupler between tank lorry and ACQC system may be hazardous or toxic to human operators, therefore robot automation is essential. Due to tight tolerance between couplers, even small pose error may result in very large internal force. In order to resolve the problem, compliance between male and female couplers should be introduced with 6-axis compliance device with F/T sensing. The proposed robot automation system consists of a collaborative robot, 6-ax is compliance device with F/T sensing, linear gripper, and robot vision. The position/force control algorithm and experimental results for assembling chemical couplers are presented.

This paper proposes the system model that is more efficient and active than formal home automation system and it can conquer the limits of formal one using intelligent mobile robot. This system uses specialized intelligent mobile robot for home environment and the robot moves around home instead of human. We call the system model to HAuPIRS (Home Automation system using PDA based Intelligent Robot System). HAuPIRS control architecture is composed three parts and each part is User Level, Cognitive Level, Executive Level. It is easy to use system and possible to extend the home apparatusfrom new technology. We made the PBMoRo System (PDA Based Mobile Robot System) based on HAuPIRS architecture and verified the efficiency of the system model.

Construction automation is yet to be improved since construction site still faces a lot of high risks and difficulties. This research focuses on applying robotic beam assembly system in place of construction workers. This system consists of CF (Construction Factory) structure to provide adequate working environment to robot automation. The CF structure not only gives automation environment for a robot but also houses the equipments to protect from outside effects. The robotic beam assembly system also consists of robotic bolting system and robot transport mechanism. It utilizes various tools to insert and join the bolts and nuts. Visual servoing helps precise robot motion by sensing bolt hole and tail of the bolt. ITA system helps non skilled workers to easily perform the assembly work with the robot system. The robot transport mechanism includes sliding rail and cross-wired lift. It carries the robot to a desired position for assembly work.

The need for synthetic automation is increasing in preparation for a gradual decrease in laboratory research manpower due to low birth rate and aging. In this study, the existing laboratory synthesis method is analyzed based on the systems engineering technique. Then, it led to the derivation of the system requirements for a fixed-based robot manipulator capable of recognition, decision and control. The robot is equipped with replaceable modular end-effectors and designed depending on the purpose and process of the synthesis. The robot with an end-effector was implemented as PoC(Proof-of-Concept), and the functions for pipetting automation was verified.

Construction robot-based automation can contribute to productivity and quality improvement by replacing manpower in tasks that have simple repetitive properties or require high precision. In this respect, layout work is one of the most effective tasks in introducing robot-based automation technology. The development of a robotic layout system for building structures has recently been promoted in Korea, and a prototype of a marking robot has been produced. However, for commercialization, the technology improvement is required through the analysis of major improvement directions. Therefore, this study aims to derive the improvement priorities of the marking robot based on the evaluation of researchers who participated in the development process. As a result, there was a high demand for improvement in factors such as the robot's precise positioning method and robot size and weight. The results of this study are expected to serve as guidelines for the efficient input of limited resources in the future technology development process.

Agricultural automation has become more and more important by environmental change. The automation demands the highest technology due to the ever changing various conditions in agriculture system. In the paper, semi-autonomous pesticide spray robot system has been developed for rose farming in the glass house. The robot is in autonomous mode during pesticide spraying process driven on pipe rail. The robot is manually driven while moving from a rail to the next rail. The drive platform and autonomous operation control system are developed based on IT fusion technology. The pesticide spray system is also developed with nozzles and booms for precision mist spray system. Experimental data of nozzle test is also included.

This paper encompasses a general technology in robot deburring automation using solid rotaing burr tools. Deburring is a cumbersome area in finishing technology, where design concept and system implementation is based on knowhows and experiences rather then theoretical development. In the field engineering it is diffcult to find a clue to where and how to start the system design. This paper presents a guide inselection of tool concept of geometry and material. Also, the concept of tool compliance system is introduced, which is one of the most important factor in robot deburring. Typical problems encountered in the field are classified into 20 categories and the solutions are suggested by the proven technology from the expertise. Special problems in polymer and diecasting areas are also briefly mentioned.
