Abstract: It is of great significance to develop devices which can support the elderly, disabled lower limbs persons and mobility degraded patients in their daily activities such as transferring from bed to wheelchair or from wheelchair to toilet and so forth. It is evident that the assistant of human in these activities especially in toilet activity cause uncomfortable for both of them in term of physical and psychological health. This paper presents the concept design and the experimental results of a full-sized prototype assistive mobile robot with lift, transfer and locomotion functions, which confirms the design effectiveness. The experiment results indicated that the robot with flexible dynamic giving excellent moving ability in narrow space. Furthermore, self-locking mechanism in all operations as well as tilt angle alert sensor give absolutely safety ability.
