The Design For Health Care Robot Auxiliary Stand System

With the rising of national living standards as well as the rapid development ofmedical and public health, our country has entered the aging society, and theproportion of the elderly population in the total population is increasing day by day.Due to the poor self-care ability of the elderly, they rely on home care mainly which ishigh cost of care and very laborious, so the conditions need to be improved. TheHealth Care Robot can be a good solution to this problem. It will improve the qualityof life of the elderly and the disabled, and ensure the stable development of society.However, the elderly and the disabled people in the bathing process cannot be like anormal person standing up or sitting down easily, due to the growth of the age, or theaccidental injury, their lower extremity joints may not be sufficient to support theirbody weight. At the same time, the space of the personal health care robots is limited,the intrafamilial transmission device needs been connected with the seat, and in orderto ensure that the intrafamilial transmission in the posture of standing and sitting, aspecial auxiliary stand device is required.Therefore, an adjustable-ups assisted standing system is designed to adapt to thedifferent body types, which can reduce body weight, and meet the requirements ofhealth care robot. Firstly, it is analyzed the process of movement on the human bodystanding,and is introduced the overall design of the health care robot, through theanalysis of the requirement of the overall program of health care robot, a folding twodegree of freedom auxiliary function standing seat is designed which can realizecoordinated movement when the user standing to back, and can support the bodyweight adjusting automatically. The kinematics and dynamics simulation are carriedout. Secondly, through the comparative analysis of the existing control system,combined with actual of the auxiliary standing seat, the control system is designed.Then, according to the general requirements of the control system, the hardware ofsystem is selected and purchased, and an experimental prototype is manufactured.Finally, the motion control program is written, the feasibility of experimental prototype is texted, and the experimental data is preliminary analyzed, which provide abasis for the further optimization of the prototype.The results show that the design of the auxiliary standing system not only canmeet the requirements of health care overall design of the robot, and solve the difficultlong-standing problem for the Senile and lower limb mobility impairments in the bathprocess effectively, improve their lives self-care ability and quality of life.
