Inorder to express the feel of touch, a feedback control is requiredwith short sampling period.  To address this issue, RT-Messenger wasproposed and implemented.  RT-Messenger is a new communicationmechanism which makes it possible for real-time applications tosatisfy these time constraints.  This mechanism is device independent,i.e., it can work without any real-time communication media.  Toevaluate the performance of proposed mechanism, a feedback control wasimplemented with RT-Messenger on RT-Linux.  The results show thatcommunication within every 1\\,[msec] sampling periods was wellachieved, and the jitter of the control was within 1.5\\,[%].","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"196","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"189","bibliographicIssueDates":{"bibliographicIssueDate":"2001-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"42"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"マルチメディア通信"}]},"weko_creator_id":"1"}}
