Abstract: Abstract: Based on the user demands, this study proposes a new human-robot system (HRS) mode of restaurant service robot, and discusses the method of applying the quality function deployment (QFD) theory to the design of human-robot ergonomics (HRE) for restaurant service robot. We use sampling survey, questionnaire survey and KJ to obtain hierarchical model of customer demand for restaurant service robot, introduce the rough analytic hierarchy process (RAHP) to calculate the weight of each demand feature, and analyze the key design objectives of the HRE design method based on quality function deployment. The crucial needs of users are transformed into design elements, then we set up the detailed demand characteristics of function, appearance and human-robot in HRE design. Through the house of quality to research on the quality function and get the design scheme, we use CATIA human-robot analysis software to evaluate the usability of the design scheme and verify the feasibility. The research results show this method has improved the usability of restaurant service robots and provided a reference for the subsequent designs.
