多功能智能轮椅设计—功能模块的开发设计

北京理工大学珠海学院2020届本科生毕业设计Multi-functional intelligent wheelchair design -the development anddesign of functional modulesAbstractThe world is entering a stage of aging,whether developed or developing countries,almost every country is facing the problem of aging.For many elderly people and people withdisabilities,a normal wheelchair cannot operate on its own and often requires the help ofothers to move effectively.Thus,the requirements for ease of use and reliability ofwheelchairs are a relatively ideal solution.However,at present,the general electricwheelchair does not have the functions of navigation,positioning and active obstacleavoidance.This topic focuses on the multifunctional intelligent wheelchair,setting and designingfunction modules,as well as the structure and configuration of the processor,and theconstruction and configuration of the processor environment.The development and design ofthe navigation system and the speech recognition system are realized.Among them,raspberryPI is used to build ROS robot environment,data collection is carried out through lidar,controlmode combining automatic and manual control is adopted,and man-machine interactiveoperation is adopted to realize the functions of automatic positioning and navigation ofintelligent wheelchair and real-time obstacle avoidance.In addition,the intelligent wheelchaircan plan the route of the target point according to the user's control/voice command,continuously detect the data information of the surrounding environment,avoid obstacles,andmodify the movement route in real time during the self-drive to ensure that the intelligentwheelchair can reach the target site safely and accurately.Keywords:intelligent wheelchair;Raspberry pie;Lidar;self-navigation;Speechrecognition
