Firstly, the finite element model of the battery box was established by using ABAQUS. The battery box was geometrically cleaned, the composite material of the box structure and the foam material of the battery module were defined, and the grid was divided according to the process of finite element analysis. Then, based on the actual application, the boundary conditions were set and the load was applied to solve the problem. Finally, the stress and failure factor of the composite battery box under the sudden braking and sharp turn of the bumpy road were analyzed, and the strength of the battery box was checked. The results show that under the two combined conditions, the maximum stress of the battery box is less than the specified stress of the composite material, and the failure factor is much less than 1, meeting the strength requirements of the battery box.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133212984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simulated vehicle detection standard is used as an initial condition for dynamic simulation of the inertial protection mechanism. The simulation results show that the inertial protection mechanism can be switched to the inertia protection mode in 0.2ms, The mechanism ensures the safety of the passengers inside the vehicle by overcoming the risk of the side door accidentally open when the vehicle is hit by the side.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133219976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pill bugs can travel effectively along pile of dead leaves, weeds, and most nature environment and the biological structures of the pill bugs fit the practical, soft and flexible design concept of the soft robotics. This biological case can be applied to soft robots to overcome the real harsh natural environment by three bionic designs: 1) flexible origami exoskeleton, 2) soft internal muscles, 3) bionic pereiopods. The origami exoskeleton is used to protect the body and reduce the friction between the robot surface and the environment. The soft internal muscles support the completion of the corresponding function with the exoskeleton and other structures of the robot. The bionic pereiopods ensure that the Pillbot can perform a variety of crawling movements. As a result, Pillbot can crawl, turn effective in the real environment, and the innovative designs for Pillbot will be applied to soft robots that are used in a harsh realistic environment.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127566052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, by establishing a kinematics positive solution model, the law of the contour error of the tool tip and the contour error of the tool orientation are revealed, which provides a theoretical basis for the contour error compensation control. Based on this, a contour error compensation control method is designed. Simulation experiments show that the control method can effectively reduce the contour error.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114518223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper was based on the portable fast battery diagnostic instrument, which quickly checked the lithium iron phosphate battery packs with different degrees of aging to determine whether the battery management system and the battery modules were connected properly. Furthermore, the constant current discharge curve of the battery was analyzed, and the internal resistance of each single cell in the battery module was obtained, thereby characterizing the difference in the aging degree of different single cells. Finally, the same battery module was tested using a portable fast battery diagnostic device. The verification found that after the battery management system and the single battery connection problem were eliminated, the portable device obtained the same result under different detection conditions, and the battery module was aged. The single cell was judged to be a problematic single cell because the internal resistance was too large and the open circuit voltage was too low. The portable device has low cost, simple operation, convenient and fast, and is suitable for rapid troubleshooting and internal resistance detection of the battery module in the field, and does not affect the life of the battery pack itself. The results of the fast battery diagnostic process are reliable and can provide a reference for the promotion of the rapid diagnosis of power batteries.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122374722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation results showed that the stress distribution was in a dynamic change process during elliptical vibration turning. Compared with conventional cutting, EVT technology can increase the shear angle, and the chip formed in the EVT process was thinner and had larger bending degree. Therefore, EVT technology has important application value in prolonging the service life of tools and improving the cutting performance of plastic materials.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128621336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
