However, detuning and multipath interference caused by the nearly all-metal environment of the data center inherently result in false positives and false negatives. The purpose of the study is to investigate the challenge of tracking assets with a handheld RFID reader in a data center and to propose a novel method to improve its performance. We found that the handheld approach can achieve high accuracy in the reading of tags; however, it is highly skilled, time consuming, and manual intensive work. The preliminary evaluation of the tag, the reader sweep, the discovery of the dead zone with the power mapper, and real-time inventory management were adopted to implement such a method. The experimental results revealed that the proposed method can achieve 100% accuracy performance. The findings of the study may serve as a guide for other RFID-based systems for static asset tracking in a metal cabinet.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131728271","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}

Generally, the nonlinear pendulum system is applied for a basic problem of stabilizing attitude/angle. However, the system possesses strong nonlinearities such that the problem is hardly solved and investigated. Using fuzzy modeling approach, the system is described via several sub-linear time-varying polynomial systems and membership function. Moreover, the time-varying parameters in the sub-linear systems are represented by the Linear Parameter Varying (LPV) model. Based on the polynomial structure, the number of fuzzy rules can be reduced to relax the control problem. With the modeling approaches, the nonlinearities and time-varying parameters in the system can be completed described. For the corresponding model, some sufficient conditions are derived into polynomial case for applying Sum-Of-Square (SOS) programming. Finally, a numerical simulation is provided to demonstrate the applicability and effectiveness of the proposed design method.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127820557","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 gripper is fabricated from ribbon paper in a few tens of seconds only by folding and engaging without adhesives. The gripper forms a four-linkage underactuated mechanism which realizes human-finger-like grasping. Simply sliding a gripper edge into a shaft slit of a rotational motor, the gripper is instantly attached and detached from a robot. Therefore, it is expected to realize a practically disposable gripper. By experiments of repeatedly grasping some foods, the reliability and durability of the gripper were shown. The gripper’s spring effect, naturally given by paper material, was shown to hold slippery and irregular-shaped foods firmly.","PeriodicalId":217521,"journal":{"name":"2022 25th International Conference on Mechatronics Technology (ICMT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130555513","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}
