As the requirement of user for robot functionality, the function and interface for controlling the robot system is more sophisticated and complicated. Accordingly development process of robot is more complicated and it takes much longer time to develop a robot system. Software development using project management tool is more important in software engineering because of the complexity of software, especially robot system. This paper proposes SEED (Software Engineering Equipment for Development), which is a web-based and integrated software engineering tool to provide independent tools for robot software development. SEED includes the document management tool, the software configuration management tool, the software testing tool on developing robot software and provide a functionality of collaborated and remote development due to WEB-based operations.

Middleware offers function that user application program can transmit data independently of network device. Connection management about network connection of module is important for normal service of module base personal robot. Unpredictable network disconnection is influenced to whole robot performance in module base personal robot. For this, Middleware must be offer two important function. The first is function of error detection and reporting about abnormal network disconnection. Therefore, middleware need method for network error detection and module management to consider special quality that each network device has. The second is the function recovering that makes the regular service possible. When the module closed from connection reconnects, as this service reports connection state of the corresponding module, the personal robot resumes the existing service. In this paper proposed method of network connection management for to support fault tolerant about network error of network module based personal robot.

In this paper we present a cleaning robot system for an autonomous mobile robot. Our robot performs goal reaching tasks into unknown indoor environments by using sensor fusion. The robot's operation objective is to clean floor or any other applicable surface and to build a map of the surrounding environment for some further purpose such as finding the shortest path available. Using its cleaning robot system for an autonomous mobile robot can move in various modes and perform dexterous tasks. Performance of the cleaning robot system is better than a fixed base redundant robot in avoiding singularity and obstacle. Sensor fusion using the clean robot improves the performance of the robot with redundant freedom in workspace and Map-Building. In this paper, Map-building of the cleaning robot has been studied using sensor fusion. A sequence of this alternating task execution scheme enables the clean robot to execute various tasks efficiently. The proposed algorithm is experimentally verified and discussed with a cleaning robot, KCCR.

This paper presents an algorithmic approach used in the development of a task-level off-line programming system for the efficient applicaiton of robot. In the method, robot tasks are graphically described with manipulation functions. By applying robot language these graphic robot tasks are converted into commands for the robot. A programming example demonstrates the potentiality of task-oriented robot programming.

In the development of an underwater construction robot, the reliability of the operating system is the most important issue because of its huge maintenance cost, especially in a deep sea application. In this paper, we propose a new redundant architectural design for the hydraulic control system of an underwater construction robot. The proposed architecture consists of dual independent modular redundancy management systems linked with a commercial profibus network. A cold standby redundancy management system consisting of a preprocessing switch circuit is applied to the signal network, and a hot standby redundancy management system is adapted to utilize two main controllers.

As robotics systems are becoming more complex there is the need to promote component based robot development, where systems can be constructed as the composition and integration of reusable building block. One of the most important challenges facing component based robot development is safeguarding against software component failures and malfunctions. The health monitoring of the robot software is most fundamental factors not only to manage system at runtime but also to analysis information of software component in design phase of the robot application. And also as a lot of monitoring events are occurred during the execution of the robot software components, a simple data treatment and efficient memory management method is required. In this paper, we propose an efficient events monitoring and data management method by modeling robot software component and monitoring factors based on robot software framework. The monitoring factors, such as component execution runtime exception, Input/Output data, execution time, checkpoint-rollback are deduced and the detail monitoring events are defined. Furthermore, we define event record and monitor record pool suitable for robot software components and propose a efficient data management method. To verify the effectiveness and usefulness of the proposed approach, a monitoring module and user interface has been implemented using OPRoS robot software framework. The proposed monitoring module can be used as monitoring tool to analysis the software components in robot design phase and plugged into self-healing system to monitor the system health status at runtime in robot systems.

오늘날 멀티 로봇에 대한 연구는 단순한 싱글 로봇들의 효율적인 운영을 넘어 공간탐색의 효율성 극대화 및 넓은 공간에서 각 로봇간의 중복작업 및 충돌 회피를 위한 부분에 집중되어 있다. 이러한 멀티 로봇을 효율적으로 운영하기 위해서는 각 싱글 로봇을 제어하고 효율적으로 작업을 할당 할 수 있는 관리체계가 필요하다. 이에 본 논문에서는 RFID를 기반으로 각 싱글로봇의 탐색공간을 효율적으로 할당함으로서 싱글로봇간의 중복 탐색을 최소화 할 수 있는 멀티로봇관리시스템을 제안한다. 또한, 탐색 작업의 완료 보장과 탐색 성능의 향상을 위하여 장애가 발생한 싱글 로봇을 탐지하고 대체 할 수 있는 고장 허용 기법을 제안한다. 제안한 시스템에서는 정확한 위치 파악이 힘들었던 기존 중앙 서버의 단점을 RFID 시스템과 홈로봇을 활용하여 극복하였다. 지정된 홈로봇은 각각의 싱글 로봇을 효율적으로 관리하며, RFID 태그의 위치 정보를 활용하여 각 싱글로봇에게 최적의 탐색 공간을 할당 한다. 제안하는 멀티로봇 관리 시스템은 공간 할당, 위치 추정 기법, 맵 생성 기법(Localization및 Mapping)을 효율적으로 수행하기 위해 RFID를 기반으로 하며, 싱글 로봇 시스템과 비교하여 시스템 운영의 효율을 극대화할 수 있을 뿐만 아니라 각 싱글 로봇의 상태와 주변 상태를 고려한 고장 허용(fault tolerance)을 제공함으로써 로봇 운영의 신뢰성을 보장할 수 있다. 본 논문에서는 시뮬레이션을 통해 제안한 시스템을 적용한 멀티로봇 시스템과 기존의 멀티로봇 시스템의 탐색 소요시간 및 중복 탐색율을 비교하여 제안한 시스템의 효율성을 입증하였다.

Automation in construction has been restricted to special classes of tasks. Curtain walls can be handled like standard construction materials; they are heavy but breakable, and are large but require precise installation. These characteristics make the installation of curtain walls ideal for robotic automation. There are two methods for developing construction robots: The first is approving the robot performance and applying it to the current construction methods. The second is admitting the limitation of the current robot technology and trying to optimize the current method of construction to apply the robot system. In this study, we derived the performance requirements of a curtain wall-installation robot. We also tested this robot at a real construction site and evaluated its performance. Finally, the results were analyzed, and we proposed additional research.
