Cloud systems are efficient models that can utilize various infrastructures, platforms, and applications regardless of the type of clients. This paper proposes a cloud-based integrated development environment (IDE) for robot software development which would make software development easier. The proposed system provides robot simulation to test the robot HW modules or robot systems for development and testing of software operating in a robot system with two or more different operating systems (OS) such as Windows, Linux, and real-time OS. This paper implements and evaluates the proposed system using OPRoS [33].

An autonomous reconnaissance ground robot performs its duty in various different environments such as mountain-scape, desert and under-water through changing its shape and form according to the environment it is working in. Making a prototype robot for each environment requires extra cost and time. It is also difficult to modify the problem after production. In this paper, we propose the adoption of M&S(Modeling & Simulation) environment for the production and design of the autonomous reconnaissance ground robot. The proposed method on the M&S environment contributed to the more effective and less time consuming production of the robot through the Pre-Modeling and Pre-Simulation process. For example, we showed the design and implementation of the autonomous reconnaissance ground robot under the proposed environment and tools.

C 언어는 AVR사의 ATmega128을 기반으로 하는 교육용 로봇 팔의 주 프로그래밍 언어다. C 언어는 교육용 로봇 팔을 제어하고 프로그램 학습하기 원하는 중학교 또는 고등학생들에게는 매우 어렵고 복잡하였다. 더구나, 통합개발환경, 디버딩 및 테스팅 환경도 제공하지 못하였다. 본 연구에서는 이러한 문제를 해결하기 위하여 교육용 로봇을 위한 자바 기반의 통합 개발 플랫폼을 제안하였다. 이 플랫폼은 교육용 로봇 팔을 위한 최신의 초소형 자바 가상 머신(NanoVM), 이클립스 플러그인을 사용한 통합개발환경, 실제 로봇을 연결하지 않아도 테스트 및 디버깅을 할 수 있는 3차원 시뮬레이터를 포함하고 있다. 이러한 자바 개발환경은 어린 학생들이 매우 용이한 교육용 로봇 팔 학습환경을 제공하게 되었다.

The purpose of this study is to ethical review on the development and service with care assistance robot. An integrative review concept analysis method was used. We analyzed the classification and role of service robots, the concept of the robot ethic and the care ethic. And there were derived the development and service about care assistance robot in ethical viewpoint. For improving current care problem, government had support to developing four types care assistance robots. But there were provided carefully care service due to the limitations of robot technology and lack of overall social awareness with care robot. In addition, in order to be successfully application in the field, care assistance robots were developed to provide high-quality care service that can consider to personal culture and living environment with the development of artificial intelligence and robot technology, as well as ethical care service.

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.

Among the prerequisite abilities (perception of environment, path planning and position estimation) of an autonomous mobile robot, position estimation has been seldom studied by mobile robot researchers. In most cases, conventional positioin estimation has been performed by placing landmarks or giving the entrire environmental information in advance. Unlikely to the conventional ones, the study addresses a new method that the robot itself can select distinctive features in the environment and save them as landmarks without any a priori knowledge, which can maximize the autonomous behavior of the robot. First, an orjentaion probaility model is applied to construct a lcoal map of robot's surrounding. The feature of the object in the map is then extracted and the map is saved as landmark. Also, presented is the position estimation method that utilizes the correspondence between landmarks and current local map. In dong this, the uncertainty of the robot's current positioin is estimated in order to select the corresponding landmark stored in the previous steps. The usefulness of all these approaches are illustrated with the results porduced by a real robot equipped with ultrasonic sensors.

A mobile robot system is developed to inspect the condition of industrial facilities under hot environment. The mobile robot is equipped with internal and external heat insulating material, an internal cooling mechanism, two CCD cameras, wireless communication devices for both the control and image signals, and an embedded controller. The portable controller is equipped with two joysticks for both the mobile robot and the inspection CCD camera, an LCD monitor, and several buttons. The developed mobile robot travels on the internal floor in hot furnaces by operators' joystick operation, captures the images of facilities in the furnaces using a zoom CCD camera, and sends the images to the portable controller through wireless communication. The mobile robot can be operated without any problem under hot environment less than 400$^{\circ}C$ in 30 minutes. This kind of automatic inspection mobile robot can be helpful to prevent significant troubles of industrial facilities without danger of human beings under harmful environment.

In this work, a 4-DOF industrial robot system with three translational and one rotational motions which is widely used in palletizing applications is developed. In order for small robot manufacturing companies to develop their own robot systems for CNC machining and/or general automations, the analysis and design methods of a 4-DOF robot manipulator are presented and the development of a PC-based robot controller with EtherCAT are introduced. It is noted that the robot controller is developed by using Simulink Real-Time, which can provide an integrated environment of easier control algorithm development and data logging. Through position control and accuracy/repeatability measurement results, the developed robot prototype has comparable performances with commercial counterparts. In the future works, the advanced functions of industrial robots such as kinematic calibration, vibration suppression control, computed torque control, etc. will be investigated.
