The sensor aims to measure stiffness, which is one of the information of biomedical tissue by palpation. The sensor is composed of two PVDF films, a silicone cylindrical column, and an aluminum cylinder. And the classification of hardness is concerned with the ratio of these PVDF outputs. In this paper, the output behavior of the palpation sensor was evaluated in detail by the experimental and numerical approach, and the suitable design to diagnose by the stiffness of tissue was investigated. Using the finite element analysis, the sensor output behavior was predicted. It is confirmed that the analysis is available for investigation of the dimension and the limitation of the sensor against the measuring object.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117226097","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}

Quantitative evaluation of the virtual design cycle has been plagued robot designers. In this paper, CBD technique is used to design the mobile robots. Program Evaluation and Review Technique (PERT) is used to compare quantitatively the design cycle between virtual design and traditional design. By way of comparison between the virtual design and traditional design used in the design process for the mobile robots, virtual design cycle was shortened the design cycle by more than 40 percent. And at the circumstances of same design cycle, the completion probability of using virtual design is much higher than the designs of using traditional design.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"293 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407435","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 the proposed method, an impact model of the manipulator including both compliances of joint servo and a soft material on a link is described as a 1-D.O.F impact model. Taylor expansion is introduced to more exactly estimate the peak impact force using the time that the value of time-derivative of the impact force equals to 0. As a result, the peak impact force is described as an algebraic function and can be easily and quickly estimated. Simple impact simulations using a 2-D.O.F manipulator were conducted to confirm the effectiveness of the proposed method. From the simulation results, it was confirmed that the estimated value of the peak impact force was in accordance with a peak point of a impact force calculated by numerical method.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122671801","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}

Twelve subjects were assigned the aesthetic processing task while the electroencephalogram (EEG) was recorded. Event-related brain potential (ERP) was required from the 32 scalp electrodes and the ugly buffoon picture produced larger amplitudes for the N1, P2, N2, and late slow wave components. Average ERP from the ugly buffoon picture were larger than that from the beautiful woman picture. The ERP signals shows that the ugly buffoon elite higher emotion waves than the beautiful woman face, because some expression is on the face of the buffoon. Then, chaos time series analysis was carried out to calculate the largest Lyapunov exponent using small data set method and the correlation dimension using G-P algorithm. The results show that the largest Lyapunov exponents of the ERP signals are greater than zero, which indicate that the ERP signals may be chaotic. The correlations dimensions coming from the beautiful woman picture are larger than that from the ugly buffoon picture. The comparison of the correlations dimensions shows that the beautiful face can excite the brain nerve cells. The research in the paper is a persuasive proof to the opinion that cerebrum's work is chaotic under some picture stimuli.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114534246","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}

But, its subjectivity and ambiguity make it difficult to quantify skin conditions. Therefore, development of measurement device which can evaluate skin conditions easily and objectively is demanded by dermatologists, cosmetic industries, and so on.

In order to design human cooperative robot that will be able to act and react with human-like features so that the robot can replace the human counterparts, we need to understand how human communicates with human first. This paper discussed the ideal characteristic of how two humans cooperate to complete a cooperative task. The cooperative task experiment involved carrying experiment object in several direction and varying the information available to the experiment subjects.
