Controller Design for Automatic Excretion Care System for Long-term Bedridden Patients

다국어 초록 (Multilingual Abstract)

This paper proposes a controller design for automatic excretion care system for long-term bedridden patients. The system can detect excrement such as feces and urine, and discriminate them severally by two built-in sensors. It is also possible to dispose of the excrement automatically without having additional efforts by caregivers. The disposal processes realized in the system are suction, collecting, washing, and drying. A controller for the automatic excretion care system is implemented and its performance is evaluated by a series of experiments. The experimental results using artificial excreta showed the developed system, the controller included, was efficient to assist the excretion care.
