본 논문에서는 장애인 자가운전을 위한 휠체어 자동탑재기능을 가지는 캐리어를 개발하기 위하여 기구학적 동특성을 분석하고 기구부의 안전성을 고려한 강도 해석을 하였다. 휠체어 자동탑재장치의 실차량 장착 및 크기를 고려한 자가운전용 차량으로는 9인승 승합차량을 선정하였다. 먼저 기구학적 동특성과 구동 방식을 결정하고, 운동 궤적 및 동작 프로세스를 참조하여 캐리어를 적용하고자 하는 승합 차량에 대한 간섭 여부를 확인하여 기구학적 개념 설계를 확정하고 기구부의 안전성을 확인하기 위해 강도해석을 통하여 설계의 신뢰성을 검증하였다. In this paper, the feasibility of a wheelchair carrier for the disabled own driver is checked kinematically to fit one of current domestic vans by drawings, design. A van with 9 passengers is selected for the modification to attach the wheelchair carrier and test the operation in real situation. The trajectory and motion process are studied to protect from the interception with outside body of van, and the conceptual design is proceeded kinematically. For the detail design, the stress analysis and driving mechanism with power supply must be studied and selected basically.

In this paper, the feasibility of a Rider Robot using Omni Wheel Drive is studied and designed for the detail design for the disable and the elder. The conceptual and basic design is derived from the abroad conceptual cars and robots related to the welfare equiprnents demonstrated at the Japanese and European fares and Exhibition shows. Especially, four omni wheels are adapted for the free steering mechanism. The variable mechanism of basic structure is used for the wheelchair in a building and the scooter outside as a robotic electrical vehicle. And the automatic controlled driving mechanism is designed for the severe handicapped and the weak elderly. The driving mechanism with power supply and several sensor system and the material of roller and the structure with anti vibration mechanism for omni wheel must be studied and selected basically. The output will be used as one of Neighbor Electrical Vehicles at universities, companies, airport, golf field, and play grounds for the mobility of the elderly and the disables and families.

The variation of the warp yarn tension in the weaving process causes the irregularity of the weft density of woven fabrics. In particular, the warp yarn tension varies to a great extent when the take-up speed, and the let-off speed do not coincide each other. Therefore it is necessary to maintain the warp yarn tension constant by controlling the let-off speed, considering the take-up speed and warp beam diameter. In the weaving machine developed for this study, the let-off system was driven by a servo-motor. The warp yarn tension was measured by the backrest(loading bar) movement which was in the state of equilibrium with the loading force of a spring. A load cell was connected to the spring. It was controlled by PI controller.
