The UR system can support several types of robots and mobile robots from an environment. Moreover, human can also be supported by UR system.

In this paper, the wireless time synchronization module is proposed as one of the solutions of time synchronization for distributed devices, and evaluated through the experiment.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123810946","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}

One of the key technologies of the directional drilling is a rotary steerable system (RSS). Among several types of RSS developed so far, `point-the-bit' and `push-the-bit' are the most commonly used ones. In this paper, a new rotary steerable system using hybrid 4-pad system is introduced. This mechanism improves the steering angle by taking advantages of both `point-the-bit' and `push-the-bit' types. We describe the detailed structure and kinematics of this system.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124235981","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}

All elements and functions in the proposed MFL (Magnetic Flux Leakage) system were designed to minimize friction between magnetizer and pipe wall and maximize defect detectability. To enhance driving performance and the ability of obstacle-negotiation, shunting system that can control direction of magnetic flux was developed.

The framework consists of selection of candidates of interest, recognition, and tracking. Instead of trying to recognize objects from a whole image at any certain time using one-size-fit-all method, we're going to select candidates as possible objects of interest first and get rid of fake candidates using a probability based method similar to particle filter in series of images. Each candidate in small cut-out image is under processing by various and specific image processing techniques to recognize object, then it is transferred to tracking phase with object ID. We perform a simple test for an artificial landmark to show feasibility of the proposed framework.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126462165","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}

As detecting step initiation is an important factor for the exoskeleton to assist the operator's movement as immediately as possible, many studies have been done to detect step initiation faster by using heel-off time, or toe-off time. In this paper, we detect step initiation faster than other approaches with, in particular, vertical ground reaction forces. Also, we present an insole-type force sensing resistor that can be applied to the UTRCEXO to get similar events, like ground reaction force events, and can detect step initiation. With our new approach, the UTRCEXO can not only detect step initiation faster, but also assist the operator's movement more quickly.","PeriodicalId":431699,"journal":{"name":"2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125979859","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}
