Design Of Lower Limits Rehabitation Robot

Paralysis has a high incidence in our country, such as stroke, cerebral blood vessels, highblood pressure and other diseases can cause paralysis or complete paralysis. Lower extremityhemiplegic rehabilitation robot is an important branch of medical robots, hemiplegic limbmotor relearning theory is the basis, lower extremity hemiplegic rehabilitation robot integratesthe rehabilitation medicine, human anatomy, robotics, computer technology, sensortechnology, mechanics, automatic control technology and other subjects, is the current hottopic of domestic and foreign country. Lower extremity hemiplegic rehabilitation robotsbelong to exercise training robots, its main task is to simulate real gait, achieve lower limbrehabilitation training for patients. In the course of the entire robot working, mainly throughthe movement of the robot to drive patients’ palsy lower limb, so that the robot can simulatenormal gait in the traction, so as to achieve the purpose of exercising lower limb muscles, andfurther be able to restore the control function of the nervous system to walking, eventually thepatient can free from the pain. According to the mechanical structure of lower extremityhemiplegic rehabilitation robot can be divided into categories of industrial robots and robotexoskeleton.I put forward my own design technique of lower limb paralysis rehabilitation robot byreferring a large literature and fielding surveys. Compared with the previous hemiplegicrehabilitation robot, the innovation of this research lies in four aspects. First, throughobservation and measurement of normal people’ and patients’ exercising process, whichestablishes training controlling strategy, the controlling strategy including active and passivestrategy, in order to guarantee the safety, I take the force control switch to prevent incidents inpassive strategy; second, a certain degree of freedom of the lumbar support is designed, makethe patient feel comfortable in the movement, further reduce the lumbar motor radial force, toprotect the motor system; third, safety and protection measures are strong; fourth, which hasthe advantages of simple operation, convenient use, function upgrade easy, safe and reliableoperation.
