Prototype Design Of An Intelligent Mobility Aid

Our country have entered the aging society for a long time. This is a very bigvulnerable groups, and it will cause a lot of social problems, so we must payattention to and take care of older persons. With the older age, the most prominentproblem is the physical machine frail elderly. Therefore, the demand of elderlywalkers is great. But now the traditional walker cannot meet the old man to safetyand comfort requirements, and it does not walk effort. Consider the robot technologywith traditional walker combine, design an intelligent robot walker. The intelligentrobot walker meets the needs of the elderly, and is Inexpensive to can be accepted bythe average family.Through investigating a number of elderly persons and review a number ofnursing homes, this paper is determined to design the intelligent robot walker whichis mainly for poor eyesight, physical weakness or muscle weakness in the elderly, fortheir usual walking exercise. The walker robots are mainly used on flat ground, andits speed is control and it can turn right and left. And the walker is capable ofautonomous obstacle avoidance to meet the old man to safety, comfort and effortrequirements.Firstly, I do the mechanical structure design of the walker robot. In this paper,Describes the robot design goals, explain the mechanical design and componentselection process, and then analysis the robot kinematics in detail.And then design the hardware circuit of the walker robot control system. First,Select the controller and the appropriate sensor. Then I design the interface circuit ofthese sensors and a motor drive circuit.And later on I design the walker robot control system software. I design eachmodule program and do the obstacle avoidance and human-computer interaction partof the program design, and finally complete the whole system programming.Finally, I do the design of the robot walker experiments, we examine theavoidance procedures and interactive programs. And in the experiment of walkerrobot design, it is the same as what is designed.
