Mukai","doi":"10.9746/SICETR.55.25","DOIUrl":"https://doi.org/10.9746/SICETR.55.25","url":null,"abstract":"Tactile sensors typically have elastic covers for reducing the impact of objects that make contact with the sensor. However, elastic covers decrease the spatial resolution of the sensor because of their low-pass spatial filtering characteristics, which vary based on the stiffness of each cover. Therefore, we propose a tactile sensor that uses shape-memory polymer (SMP) with stiffness that varies based on temperature. SMPs can be deformed above their glass transition temperature ( T g ) upon application of a small load. The reversible change in the elastic modulus between the glassy and rubbery states of an SMP can be on the order of several hundred-fold. These characteristics can be exploited to alter the spatial resolution and the rigidity of the sensor surface by adjusting the temperature of the SMP. In this study, a prototype sensor was fabricated using an SMP sheet with embedded electrical heating wires, and its fundamental performance was evaluated. The experimental re-sults of a preliminary proof-of-concept investigation conducted using the prototype confirm the feasibility of the proposed sensor. Moreover, using a 4 × 4 array of pressure sensors, it was possible to distinguish the shape of the object placed on the sensor above and below T g . The center of pressure applied on the prototype sensor could be measured by a developed program. In addition, we evaluated the control of the position of an object on the robot arm utilizing the prototype sensor attached on the arm. We could hold the constant position of the object on the sensor, although it took a longer time to stabilize the object above T g because of the deformation of the SMP.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114630468","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}

With the growth, micro-manipulation in the micro world (less than dozens of micro-order) is significant in a variety of fields. However, 3D-estimation in microscopic view is difficult. We have developed a high-precision depth estimation method based on difference between blur widths of a particle and a tip of micromanipulator in our previous study. In our proposed method, one shot microscopic image can estimate precisely a depth distance without lens parameters. However, our method has a problem of a derivation of the depth equation. We propose a technique to derivate the equation using by Robust estimation and Mahalanobis’ distance. To confirm stability and precision of the proposed technique, we show the validity through experimented results.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751057","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 recent years, man-ufacturing based on composites has increased gradually. However, the elastic wave dynamics in such materials is considerably more complicated. The conventional time-of-flight technique is not reliable for locating the defects even in isotropic plates because of the dispersiveness in the Lamb wave propagation. Avoiding difficulties caused by the dispersiveness, this paper proposes a novel imaging method based on the point-source constrained partial differential equation in order to reconstruct the silhouette image of the subsurface defects. A theoretical analysis of the proposed method is developed for single point-like defect in the isotropic plate. Numerical evaluation and several experimental results are presented to verify the image reconstruction process of the subsurface defects in the CFRP plates.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122719192","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}
