Abstract
A significant number of the elderly have difficulties in going to a lavatory by themselves. Excreting is a purely physiological requirement and it is difficult to predict when the elderly will need help of caregivers to go to the lavatory. The elderly sometimes needs to wear an adult diaper or set a portable toilet in their living space but they makes the elderly uncomfortable and insanitary. Consequently, we proposed a mobile toilet system for solving these problems. The developed mobile toilet system waits for a calling signal from the elderly at a standby room. When control signals are received, the toilet system approaches the elderly. The past system equipped a two-wheel drive system. Considering a small space such as Japanese style house, two-wheel drive is not suitable for veering in narrow space. In this study, we developed a mobile toilet system with omni-directional mobile mechanism by employing omni-wheel.
