Innovative Design Of Hexapod Robot Based On TRIZ

Hexapod robots are good performance mechanical and electrical systems which imitate biological structures and motion characteristics of organisms according to the principles of bionics.They have shown their potential use in the dangerous conditions to human beings,such as anti-terrorism,space exploration and rescue.However,on the one hand,the study of hexapod robots is still in a simple level of understanding of natural functions and characteristics,leading to a great difference in microcosmic and biological.These problems make the bionic robots similar in shape to the creatures but different in essence.On the other hand,A Hexapod Biomimetic Robot is a complex system with Multidisciplinary height intersection.There are many factors restricting the further development of the hexapod robots,such as biological mechanism,mechanism and driving design,biomimetic materials,bionic control,bioenergy utilization,control technology,and so on.By using TRIZ,a systematic and innovative method,designers break down barriers that only seek to resolve conflicts in this field,change thinking patterns,stimulate innovative thinking,and use their predecessors' innovative knowledge and experience in different fields.It can broaden the depth and breadth of innovation perspective,stimulate creative thinking,and improve the effectiveness of hexapod bionic robot innovation scheme.To achieve the accurate prediction of product development,gain high satisfaction of the consumer and innovation design based on user demand driven,the paper takes the product demand analysis as the foundation by summing up technical personnel,using brainstorming to get divergent demand as much as possible,and then through group discussion.The divergent demand is transformed into the technical requirement of semantic specification,and then the technology requirement is integrated and classified by using the law of requirement evolution.The questionnaire is designed by using Kano model,and the result of statistical investigation is used to sort out the importance of integration demand and determine the excited demand.The corresponding technical requirements in the exciting demand as the exciting demand point,obtained the control strategy is more intelligent,"grab" forelimb structure,has the ability to change the surrounding environment,improve the efficiency of solar cells,leg joint structure biophysical,The foot has the ability of grasping,the seven exciting demand points are detected in a wide range of intelligence,and the exciting demand point is taken as the innovation design target to guide the hexapod bionic robot to carry on the innovation design.For leg joint structure biochemistry,foot grasping,control strategy more intelligent these three need to predict the new technology to achieve the exciting demand points,using the law of technological evolution as a tool,this paper analyzes the development process of the key technology system to realize the exciting demand point,predicts the evolution state with potential,and forms an innovative design scheme.For other exciting demand points,this paper uses conflict,tailoring and other problem-solving tools to implement innovative solutions to excited demand points.Through this method,six innovative design schemes,such as the fusion of the leg arm and the structure of the forelimb,are proposed.The innovative design scheme of the new generation of six-legged bionic robot is established by summarizing the six innovative design schemes,and the dynamic simulation of the robot's grasping,walking,holding and holding is carried out,which verifies the rationality of the scheme structure.
