Outline of Final Research Achievements

We had planned to develop a system to support urination at night, including a non-contact urination intention detection system using a Doppler sensor. However, there was no Doppler that met the required standard.
Therefore, we focused our attention on one of the urinary support systems, a mobility aid, and jointly developed it with Ryoei Co.The concept of this toilet walking aid walker is a walker that allows a person to go to the toilet alone, even at night. It has a wheelchair-like structure without a seat, and is equipped with a calling function and a fall prevention function. The user can move and defecate without the help of a caregiver, call the walker when necessary, and return it to its original position after use. The system allows for mobility in the living lab.

Academic Significance and Societal Importance of the Research Achievements

夜間1人でトイレに行ける歩行車をコンセプに、排泄支援システムの1つであるトイレ歩行支援歩行車ロボスネイルOVERをリョーエイ株式会社と共同で開発した。本歩行車は、座面を無くした車椅子のような構造と、呼び出し機能、転倒防止機能を備えており、特にトイレに行く時に、介護者の手を借りることなく移動や排泄を行うことが可能である。本機器を活用することで、夜間の介護者の負担軽減が可能となる。
