摘要：In order to reduce nursing intensity and improve freedom of the elderly and the disabled, a multi-function nursing wheelchair which can switch chair to bed and realize many kinds of posture transformation is designed. This paper introduces the mechanical structure design （position adjustment mechanism and variable wheelbase mechanism） and co.trol design of posture transformation unit of multifunctional nursing wheelchair.

摘要：In order to achieve a wheelchair lift function, this paper designs a tri-scissors mechanism. Through the so-called H-type transmission and L-type swing rod, the three scissors mechanisms lift in the same rate with only one liner motor while ensuring the stability of the lift. Finite element analysis in ANSYS is performed to verify the material strength. The co.trol system with Sunplus SCM achieves the voice co.trol of wheelchair walking and lifting.

摘要：To achieve human lower limbs rehabilitation training, the exoskeleton lower limbs rehabilitation robot is designed. Through respective motor driving, the retarding mechanism and telesco.ic adjusting mechanism, the function of human walking is acco.plished. After the design of the mechanical structure, the finite element analysis is carried out on the important parts and the co.trol system is achieved by Single Chip Microco.puter.
