Comfort Evaluation And Application Of Exoskeleton Robot Based On User Experience

The exoskeleton robot system is a new type of human-machine intelligent system,which perfectly combines human intelligence and machine power.Studying the development status of exoskeleton robots,it is found that in the research and development of exoskeleton robot equipment,researchers focus more on the development of control methods and mechanical structures,and lack of research on user experience comfort.For exoskeleton equipment to achieve commercialization and mass production as quickly as possible,comfort is an important evaluation criterion.From the perspective of user experience,the factors that affect the comfort of the exoskeleton are analyzed,and the comfort evaluation model of the exoskeleton robot is established.The comfort evaluation model is used to comprehensively evaluate the comfort of the prototype developed by the laboratory and provide improvements.It is recommended to provide a reference for improving the overall comfort of exoskeleton robots.First,through extensive analysis and research on basic knowledge theories such as user experience concepts,content,and human biological reactions,the subjective and objective factors,physical factors,dynamic and static factors that affect the comfort of exoskeleton robots are analyzed and summarized Factors affecting the comfort of skeletal robots.Through the three-stage analysis of the exoskeleton robot user experience and the three-level theory proposed by Norman,the focus group interview method and Delphi method are used to summarize and classify the factors that affect the comfort of the exoskeleton robot,and the exoskeleton Evaluation standard of robot comfort.Secondly,an analytic hierarchy process was used to construct an index system for the comfort evaluation of exoskeleton robots based on the above comfort evaluation standards,and then a fuzzy mathematics was used to establish a comprehensive evaluation model for the comfort of exoskeleton robots.,Designed the appearance modeling scheme 1 and scheme 2 of the extremity exoskeleton robot.Finally,a five-level Likert scale was designed to conduct a questionnaire survey,and the evaluation model was used to carry out a comprehensive quantitative evaluation of the appearance modeling options 1 and 2 of the prototype.The evaluation results show that the back appearance of the prototype 1 and the comfort of the man-machine control system are poor.The improved design and the physical model are made to obtain the scheme 2.The results show that improving the design of the strap support system and the appearance of the industrial design can help improve the overall comfort of the user experience of the exoskeleton robot and provide a reference for the quantitative evaluation of the comfort of the exoskeleton robot.
