Research Of Key Technology On Climbing-stair Manned Wheelchair Robot

With the development of economy, high-rise buildings in China are increasinggradually. The situation of Chinese aging population is still grim, the elderly and thedisable’s extremely inconvenient movement makes the wheelchair playing anirreplaceable role in the crowd. when confronted with an emergency, small elevator spacebring in a tough process of transportation of rescuing, even threatening their lives.Focusing on these problems, A stair climbing manned wheelchair robot is putforward. Through comparative analysis of the existing climbing stairs agencies,according to the purpose of this paper, The planetary wheels are selected as mobilemechanism in order to meet the design requirements of moving on the flat road andwalking up and down the stairs. The robot combined with the planetary wheels, parallelmechanism and deformable seat phase, developing a stair climbing wheelchair robotwhich can smoothly go up and down the stairs as well as can be transformed into astretcher and placed in an ambulance.According to the stair climbing manned wheelchair robot’s movement, design themobile mechanism, on the basis of the movement of robot’s climbing stairs, design theprogram of leg mechanism, seat mechanism and other mechanism. Above all,3Dmodeling agencies can be built by using Pro/e software and lead the3D model in Adamssimulation software to establish virtual prototype, after adding to its constraints andmotions, simulating the mechanism and verify its rationality, through the data graphanalysis of the robot. Lay the foundations for the future continue to optimize.In this paper, the design of manned wheelchair robot goes up and down stairssmoothly and has great practicability. The robot has great effect in improvement of thepatient’s life quality and the efficiency of rescue.
