It is our purpose to develop a fine type of microrobot in pipe that has the characteristics of flexibility, driven by wireless, good response and safety in body. In this paper, we propose a new prototype model of microrobot utilizing electromagnetic actuator as the servo actuator to realize moving motion. The moving fin driven by a permanent magnet can be controlled by the frequency adjustment of the electromagnetic field. To the microrobot, which built a prototype, the running experiment was conducted and the operating characteristic was evaluated. It turns out that developed microrobot can correspond to the dirt adhering to the inner wall, or long distance movement by the experiment result, and speed control can be easily performed by frequency adjustment. The experimental results indicate that speed control can be easily performed by frequency adjustment of the electromagnetic field.","PeriodicalId":361470,"journal":{"name":"Proceedings of 2002 International Symposium on Micromechatronics and Human Science","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131090051","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 study, we have developed a new process using LIGA mold which is able to cast a microstructure of alloys or ceramics using spark plasma sintering (SPS) machine. In addition, the alloys are made by mechanical alloying (MA) method using a combination of different metal powder. A micro spring structure of Ti-Ni-Cu shape memory alloy powder was produced by way of trial. Finally, it was found that the LIGA-MA-SPS process is an effective technique.","PeriodicalId":361470,"journal":{"name":"Proceedings of 2002 International Symposium on Micromechatronics and Human Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128399867","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}

If artificial vision systems that can understand human faces are realized, they will enable machines to communicate with people more effectively. For this purpose, we have been continuing the research and development of vision-based face understanding technologies, such as face detection, facial feature point detection, face recognition, face tracking, encoding and transmission of facial motion, face situation estimation, gender and age estimation, etc. This paper introduces these technologies and their applications.","PeriodicalId":361470,"journal":{"name":"Proceedings of 2002 International Symposium on Micromechatronics and Human Science","volume":"10 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":"134103377","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}
