Research Of Sitting Lower Limb Rehabilitation Robot

With the development of society, people’s livelihood has been the focus of publicattention, and healthcare industry has gradually become a nascent industry and the pillarof the national economy. The development of rehabilitation medical equipment has alsoget government vigorously support, which have introduced a number of policies.Although the development of rehabilitation medicine in China lately started, but a goodtrend has been emerged for a variety of rehabilitation therapies and rehabilitationequipments have been exploring and researching. It is necessary to depth study inrehabilitation when people keep the state of sitting for it still less study. Research groupexplore characteristics and advantages of the human body sitting’s posture rehabilitation,and develop a lower limb rehabilitation robot that has active and passive model. Thispaper mainly related the functional properties of the lower limb rehabilitation robot.Firstly, this paper summarizes the development of present situation and existingproblems of the rehabilitation robot, and explain the meaning and purpose of the lowerlimb rehabilitation robot, the perspective of medical and the phase division of recoverywere analyzed. Through to the human body each joint of lower limb bone structurecharacteristics and the characteristics of variable cell mechanism motion analysis,combining the theory of exercise rehabilitation medicine, initiative to design a five-barrehabilitation training robot.Secondly, Kinematic analysis of human-machine systems and rehabilitation robotman-machine system model is built according to the theory of ergonomic design. Patients posture adjustment range for different height in robot is summarized because ofconsiding different populations hight and planning the extent of adjustment lever inrehabilitation robot.Finally, based on the above analysis, training institutions for rehabilitation robotmechanical analysis, in the case of a known load, the solution of two arbitrary inputshaft crank at any time the state and the forces and the use of MATLAB softwaresimulation its trend moment, mastered the mechanical properties of the traininginstitution, you can optimize rehabilitation robot for taking a step forward to improvethe foundation.This paper can be adjusted with the working status, the training mode and diversesitting lower limb rehabilitation robot phased study has important significance for the later continued sitting closer in-depth study to assess the rehabilitation robot system,rehabilitation model planning, optimization and recovery development and otherfoundation.
