Design of multifunctional combined walking aid

Abstract

Abstract In view of the lack of a portable walking aid with multiple functions in the current market, a multifunctional combined walking aid is designed. The device is based on raspberry pie, and controls the whole device through human-computer interaction of touch screen; the dynamic and non dynamic switching is realized through disassembly structure, which can have the advantages of walking aid and crutch structure; a stacked connection structure is designed, which can realize the functions of folding and drug storage in a cylindrical structure at the same time; a vertical driving wheel is adopted, which can realize the function of folding and drug storage. The independent driving of two wheels enables the user to enter the control position from the rear side of the walking aid. The experimental results of the prototype show that the device has the advantages of strong functionality, convenient operation and broad application prospects.
