By using virtual simulation technology to achieve the intuitive expression the position, orientation and surrounding of rescue detection robot, combining dynamic modeling technology to reconstruct the rescue zone, the RCS based on VR makes information consistent between VR surroundings and reality environment. The modules and their functions of the RCS based on VR are introduced, the basic theories and methods are presented as well. A VR-based RCS system and the rescue detection robot is built under laboratory conditions. The motion control subsystem, the precise localization subsystem and the dynamic modeling subsystem are integrated into the system. System function and partial performance test are completed. The results shows that these methods can collect and display the information of robot and surrounding environment. Judgment time is shortened, rescue efficiency is enhanced compared with the autonomy control of the robot.","PeriodicalId":182404,"journal":{"name":"International Conference on Ubiquitous Robots and Ambient Intelligence","volume":"5 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":"117201557","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}

Further, the operation situation of rotor system is changed. At present, the perfect conclusion has not been formed to identify torque load of rotor system. In this paper, a method was used to identify torque load of the elastic support and single-span rigid rotor system. The method utilized axis orbit as information source. Considering nonlinear oil film force, the mechanical model of single-span rigid rotor system was established and dynamics equation was deduced with torque load. The simulated orbit showed the shaft center offset downward and border amplitude increases with torque load. Based on two-dimensional image centroid, the both characteristic parameters were set up, the vertical offsets of axis orbit centroid and amplitude deviation. Torque situation of the rotor system would be identified by them. The single-span rotor test results showed the measured axis orbit was basically coincident with the simulated axis orbit. The calculate results of characteristic parameters were also consistent with the experimental results. That proved the effectiveness of this method to identify torque load through axis orbit.","PeriodicalId":182404,"journal":{"name":"International Conference on Ubiquitous Robots and Ambient Intelligence","volume":"28 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":"124582431","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}
