Design and Experiment of Multi-Modal Intelligent Elderly Assisted Wheelchair Robot

摘要

In response to the prevalent social issue of elderly individuals living alone who lack independent mobility and face difficulties in standing up and getting up, a multi-modal intelligent elderly assistance wheelchair robot has been developed to provide assistance in such scenarios. This paper presents the analysis of the assistance needs of the elderly, along with the proposed main functions of the robot. The mechanical structure of the robot was designed and verified through finite element analysis, followed by experimental verification of assisted standing, transformation of bed and chair form, assisted getting up, and knee-free bending assisted getting up functions. The results of the experiments demonstrate that the multi-modal intelligent wheelchair robot developed in this study can effectively assist the elderly living alone in completing the actions of getting up and standing, thereby reducing their physical burden in home activities and improving their quality of life. This development has potential for broader applicability in the field of elderly care.
