However, this objective remains a challenging one, partly because of the complex mechanical design requirements of adaptable admittance joints. In this work, we address adaptable joint admittance control from the perspective of simulation-driven engineering. We exploit the comprehensive, unique capabilities of eRobotics to shift adaptable joint admittance control into virtual reality. The main advantage is that the targeted joint dynamics are replicated with substantially less effort and at low costs. Moreover, it can be swiftly applied to a wide range of robot arms, therefore pushing back some of the inherent limitations of real hardware. The approach is well-suited to the understanding of compliance control, the familiarization with future compliant robots as well as training. Results of simulation conducted on a 7 DoF robot manipulator are provided to show the effectiveness of the approach.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122961669","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 order to increase load capacity, the assembly preload is often added to GFBs now. Firstly, for multi-leaf GFBs with assembly preload, this paper presents a method to fabricate the bearings with assembly preload, and the precision of the shape of the top foils is discussed. Then, the bearing deflection with static load of the foil bearing was measured. A static load, which is up to 340N, could be applied to the tested GFBs with assembly preload by a mechanical loading device, and a strain gauge type load cell was used to measure the applied static load. Finally, the stiffness coefficient of the tested bearing was estimated and a cubic polynomial of stiffness coefficient for test bearings is estimated using the measured static load versus deflection test data. The results show the radius of top foils which were fabricated by this method can be changed by different pressures and the accuracy of foil shape is improved. The load capacity and stiffness are both two times larger than bump-type GFBs.","PeriodicalId":335884,"journal":{"name":"2013 IEEE International Conference on Mechatronics and Automation","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121657827","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}
