The directional ability of an automobile has an influence on driver directly, and hence it must be given most priority. Alignment factors of automobile such as the camber, caster and toe directly affect the directional ability of a vehicle. The above mentioned factors are determined by the pose of interlinks in the assembly of an automobile front chassis module. Measuring the position of center point of ball joints in the front lower arm is very difficult. A method to determine this position is suggested in this paper. Pose estimation for front chassis module and dimensional evaluation to find the rotational characteristics of front lower arm were developed based on fundamental geometric techniques. To interpret the inspection data obtained for front chassis module, 3-D best fit method is needed. The best fit method determines the relationship between the nominal design coordinate system and the corresponding feature coordinate system. The least squares method based on singular value decomposition is used in this paper.

The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which is the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash and has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. In this paper, a Home Mess-Cleanup Robot(HMR), which has a practical function of the automatic mess-cleanup, is developed. It need functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of the self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulation system, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It need to also has the entertainment functions for the good communication between the human and HMR. Therefore, the Home Mess-cleanup Robot with Entertainmental Human Interface is developed in this paper. Finally, the good performance of the designed machine, HMR'4, is confirmed through the results of the mess clean-up and arrangement.

In this paper, Ubiquitous Home Mess-Cleanup Robot(UHMR), which has a practical function of the automatic mess-cleanup, is developed. The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which was the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash but has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. It needs functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of tile self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulate,, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. We use the RFID system to solve the problems in this paper and propose the reading algorithm of RFID tags installed in indoor objects and environments. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It needs to also has the entertainment functions for the good communication between the human and UHMR. Finally, the good performance of the designed UHMR is confirmed through the results of the mess clean-up and arrangement.

본 논문에서는 자율적이며 자동화된 정리정돈 기능을 갖는 홈 메스클린업 로봇(McBot)을 개발한다. 그 동안 진공청소기가 보급되어 집안 청소에 편리성 향상이 이루어졌지만 진공청소기를 운영하는 노동은 인간의 몫이었다. 그것을 해결하기 위하여 최근에 로봇청소기들이 개발되었으나, 진공 청소하기 이전에 해결해야 하는 신문, 옷가지 등을 정돈하거나 진공흡입하기 어려운 크기의 쓰레기들을 정리하는 것은 여전히 사람이 처리해야 하는 심각한 노동으로 남아 있다. 이러한 이유로 본격적인 청소로봇 시장이 아직 형성되지 못하고 있다. 그래서 본 논문에서는 가정에서의 정리정돈 문제를 해결할 수 있는 소위 홈 메스클린업 로봇을 개발하고 새로운 디자인 방법과 제어 기법 그리고 자기 위치 인식 알고리즘을 제안한다. 홈 메스클린업 로봇은 정리정돈을 위하여 쾌속 네비게이션과 정교한 매니퓰레이션 기능을 필요로 한다. 본 논문에서는 자율적인 네비게이션 기능으로 장애물을 회피하여 원하는 목적지까지 고속으로 이동할 수 있는 휠 기반의 이동로봇을 개발한다. 또한 정리정돈 작업을 위한 정교한 매니플레이션 기능으로 6 자유도를 갖는 로봇 팔과 리프트 등의 보조장치들을 개발하며, 그것들이 정밀 제어될 수 있는 새로운 알고리즘을 제시한다. 특히 홈 메스클린업 로봇의 탐색 시스템은 지금까지의 청소로봇들과는 달리 일정한 패턴이나 벽면을 따라 움직이는 방식이 아닌 실질적인 실내 구조의 파악과 잡은 물체를 원래의 위치로 이동시키거나 정돈 장소까지 이동하기 위한 절대 좌표 형태의 자기 위치 인식 기능이 필요하다. 그러므로 본 논문에서는 자신의 절대좌표 인식 및 물체인식을 위하여 RFID 태그들을 이용한 자기위치 인식 시스템을 개발한다. 마지막으로 본 논문에서 설계된 홈 메스클린업 로봇이 RFID 환경에서 정리정돈작업을 수행하는 실제 실험을 통하여 좋은 성능을 검증한다.
