| Abstract: |
| The work aims to analyze the user demands, principle of structure and human-robot relationships about service robot for the elderly based on the TRIZ theory, and use GA to optimize the design. Firstly, five-stage questionnaire survey and analytic hierarchy process were used to analyze the behavioral characteristics of the elderly to obtain the specific functional needs of the elderly. Combined with the TRIZ theory, the functional structure model of service robot for the elderly was derived. Secondly, the object-field model was used to establish a relatively complete design model of the new human-robot system for service robot for the elderly. Based on the functional model and the system model, the principle of physical contradiction was used to derive the configuration principle of service robot for the elderly. The principle of technical contradiction was used to improve the design. Finally, the GA was used to find the optimal solution, and visualize it and verify the research results with the principal component comprehensive evaluation. On the basis of meeting the needs of the elderly, the functional model, HRS model and structural mode are proposed.Configuration principles, optimization methods and design indicators for service robot for the elderly were proposed to provide theoretical basis for subsequent robot design. |
