Structure Design of Intelligent Wheelchair Based on FBS Model

The paper aims to solve the travel problems of the elderly and the disabled, design a kind of intelligent wheelchair to help the elderly and the disabled. Firstly, the structural elements of the intelligent wheelchair are summarized, and the operational behavior path in the actual application of the wheelchair is analyzed to explore the feasibility of the existing automatic driving technology to assist the intelligent wheelchair in driving. The FBS model is used to integrate the obtained function-behavior-structure and realize the process of mapping and transformation. Secondly, with the help of the final analysis conclusion, the structure design of the intelligent wheelchair is guided, and the iterative optimization of the scheme is carried out. The corresponding design scheme is provided for the support, connection and drive system of the intelligent wheelchair, and the intelligent wheelchair design scheme with enhanced structural function and automatic driving assistance is proposed.Finally, the dual analysis method is used to evaluate the design of the final scheme, and the rationality of the design scheme is verified by combining the obtained values and the sequence. The FBS model visualizes, transforms and refines the integration analysis of function, behaviors and structure into the requirements of structural design, which provides a certain reference value for the similar research on the structure design of intelligent wheelchairs.
