Research On The Technology Of The Five Wheeled Mobile Manned Climbing Robot

As China's economic development,high-rise buildings gradually increased,residents walk up and down the stairs,most of the length of the diagonal is only about 2 meters narrow.Some perennial bed ill or sudden patients,such as patients with heart disease,myocardial infarction,hospital requirements transport,and not many high-rise houses on the space elevator receiving medical stretcher,the patient carrying the stairs have occurred.Patients may slip during delivery.Although they have a seat belt,patients with asthma or heart failure cannot use a seat belt.Some can only supine and can't bump patients,from 10 or more multi-story buildings on the move down very difficult.The traditional wheelchair can't realize that can run on the road can be smooth up and down the stairs,while the existing stair climbing wheelchair on the stairs size demanding or too heavy.Aiming at the above problems,put forward a stair climbing wheelchair manned robot,analyzed the stair climbing mechanism,according to the walking mechanism design movement of stair climbing wheelchair robot manned,and according to the walking mechanism of stair climbing motion state determine the design scheme,the leg mechanism and chair seat mechanism the auxiliary design,on the basis of this,the robot kinematics modeling in the process of climbing the stairs,through the movement of the pair of kinematics modeling of each motion are deduced.Then through the Solid Works ANSYS of the mechanism for three-dimensional modeling and three-dimensional model into Adams simulation software,based on the added constraints and drive through the kinematics simulation,to further demonstrate its practical rationality,rely on the data obtained by the curve of robotics to carry out supporting analysis.For the continued optimization of the future laid the foundation.In the course of the analysis,we have designed a new robot equipment that can support the weight of an adult male,and can support the stable operation of ordinary roads and stairs,and also support changing into stretchers during the rescue process.The actual design work is based on the previous analysis results,and a new architecture scheme is further designed based on the systematiccomparison.Depending on the effective cooperation of various organizations,the robot can satisfy the expected flexible movement of the design,maintain the horizontal state,and carry out the stable up and down stairs activities.Referring to the actual needs of the patient,it can also be changed into a stretcher mode,easy to lie down.The manned wheelchair robot of stair climbing is stable and practical in the process of walking up and down stairs.It is of great significance for improving the mobility and the life of the elderly.The current service robots fit our social needs to grow,for more people to provide more convenient and perfect service,while the design of new arrangements for helping the disabled.To a certain extent,to alleviate the major social service problems brought by the aging of the population is of far-reaching significance to promote the coordinated development of the normal and orderly society.
