One is that the the final outcome of the system is predictable or controllable by fine tuning its initial state or parameter; another is that its prediction or control is never successful by fine tuning the initial state or parameter. Such a property, derived by non-linearity, is called final state sensitivity and is distinguished from initial state sensitivity of chaos, which is also unpredictability derived by non-linearity. The final state sensitivity is characterized by a fractal basin boundary. In this paper, we show that a locomotion dynamics of a simple biped robot has the final state sensitivity. Our model is a passive dynamic walker, which can naturally walk without input signals. We numerically calculate the model and show the existence of initial state regions that have final state sensitivity. A quantitative method using uncertainty exponents calculated from fractal dimension of a basin of attraction is employed. We confirm fractal basin boundary and final state sensitivity in both periodic-gait parameters and chaotic-gait parameters. Our result suggests that, in some sets of parameter region, the behavior of a robot becomes unpredictable as a dice, which is qualitatively different from other parameter set in its nature, requiring infinite precisions to set its initial condition to control its fate.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131323366","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}

Capacitive force sensors are simple in structure and stable in sensor output. Recently, soft capacitive force sensors, in which electrodes and dielectric are made of soft materials, have been proposed. The output of a soft capacitive force sensor depends not only on the acting force but also on the contact area between the sensor and the environment. We should remove the influence of the contact area to obtain force information alone. In this paper, we propose area-independent soft capacitive force sensor by designing the material properties of the dielectric. First, we demonstrate the dependency of capacitive soft sensor signals on contact area. Next, we build a simple model of a capacitive soft sensor to formulate the dependency. We then apply numerical optimization to minimize the dependency, which directly yields an area-independent soft capacitive force sensor.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121088871","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}

Previous studies have the index of sense of approaching for a preceding vehicle. Wada et al. proposed KdB that is an index of a sensation of approaching, KdB is focused on the area change of the preceding vehicle projected on the retina and well expresses the human perception in the approaching an obstacle. However, KdB does not express the sense of approaching for around objects because it ensured expressing the sense of approaching index for a preceding vehicle. We propose an index of a sense of approaching (SoA) that is based on KdB and considering the direction of approaching objects. The experimental results show that the proposed index represents the sense of approaching is changed like a human being. This paper discusses a sense of approaching index which is a sensation of human perception for objects approached in self-driving. Recently, self-driving cars have gained increasing global attention. An important aspect when developing a self-driving car is ensuring that the driver and passengers don't feel a strangeness under automatically controlled. Thus, the objective of this study is to realize the self-driving control based on human perception. Previous studies have the index of sense of approaching for a preceding vehicle. However, KdB does not express the sense of approaching for around objects because it ensured expressing the sense of approaching index for a preceding vehicle. Therefore, we proposed an index of a sense of approaching (SoA) that is based on KdB and considering the direction of approaching objects. Moreover, we use a spherical camera for acquiring the change of obstacles in vision to imitate the optical change on the retina. We perform an experiment using an actual vehicle that a vehicle approaches an obstacle and avoid a collision. As a result, the proposed index reperesents the sense of approaching is changed like a human being.","PeriodicalId":264161,"journal":{"name":"2019 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133414965","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 DNA-damaged fibroblast cell rates were 8.0%, and the blastocyst formation rates were 22.1 % after NT. The level of H3K4me3 was similar to NT, parthenogenetic and androgenetic embryos. On the other hand, the level of H3K27me3 was higher in NT and parthenogenetic embryos than androgenetic embryos. These results suggest that abnormal reprogramming may cause pregnancy loss after embryo transfer of NT embryos using FD cells.

Several different kinds of fibers are fabricated and assembled as a module of the tissue structure. In this paper, the sensor fiber and muscle fiber are used for demonstration of the proof of concept. After the assembly, the micro-fibers were successfully fused to form a tissue structure with highly arranged cells inside.
