Such a situation may arise when the sensors are kind of limit switches and actuators are on/off control architecture while control specification is to be achieved as accurate as possible. An experimental setup is taken to clarify our problem setup. The experimental setup is a ball position control system in which a small iron ball rotates on a beam. For the experimental setup, we propose a control algorithm based on discrete input and output and continuous state estimation. Finally, the proposed method is applied to the experimental setup to demonstrate its effectiveness as well as numerical simulation.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127230959","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}

The calibration of position error in model-based method implements four steps: kinematic model definition of the robot, measurement process of the robot's positions, identification of the kinematic model of the robot and compensation of the position errors. This method is both time consuming and complicated because of the identification and compensation processes. Most traditional modeless methods are relatively simple and practical, but the calibration accuracy is relatively low and most of them are only suitable for the robots calibration in 2D domain and in relative small workspaces. This paper provides a novel modeless fuzzy interpolation method to improve the compensation accuracy for the robots calibration in 3D workspace. A comparison between the model-based and modeless fuzzy interpolation calibration method is made. The simulated results show that the modeless fuzzy interpolation calibration method is compatible with the model-based calibration method, and even outperforms a model-based counterpart in terms of accuracy and complexity in small workspaces.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126768814","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}

The tightly coupled integration approach has the advantage over the loosely coupled approach by using raw GPS measurements, but hence introduces nonlinearity into the measurement equation of the Kalman filter. So, linearization is usually used. Consequently, the errors of linearization may make the Kalman filter unstable or even divergent, especially under the situation that low quality inertial devices are included. To solve this problem, an improved tightly coupled approach by adding second-order derivative information to retain some nonlinear characteristics is proposed in this paper. Simulation results indicate that the nonlinear terms included in the filtering process greatly influence the performance of integration, especially in the case where the low quality INS is used in the integrated system.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126832932","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}

The output is driven by a five bar mechanism, which, in turn, is driven by a servo input and a reference input. By choosing the correct trajectories of the servo input and the starting position, the torque sharing characteristics can be improved, such that the lowest rating servo motor will suffice. Thus providing flexibility at a reduced cost. Also the reference input which can be a constant speed motion can be derived from some other source, thus not needing a dedicated motor. Such a device can replace cams in applications where the functional relationship between the input and the output motions changes from time to time, such as packaging equipment and control of valve timings of IC engines. The PHM setup has been designed and fabricated. Simulation of the mechanism is carried out using ADAMS, to determine the size of servo motor. An approach to determine optimal control input to the mechanism for a given output profile is discussed. The experimental setup allows users to generate various cam profiles and study the deviations. Various profiles were generated within reasonable accuracy. A typical cam profile has been considered and optimization of control trajectory results in RMS torque reduction of 57%.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126526201","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}

The reasons for this may centre on the diversity of robotic hardware, limitations on performance, and the need to perform complex and diverse tasks. The result of using such specialised software is an almost non-existent level or software portability. It is proposed that the use of abstraction can enable the use or component software and bring with it the benefits or reuse. Abstraction of robotic hardware and software is difficult, and it is clear that a single robot abstraction is not practical due to the degree or diversity. It is proposed that some middle ground between specialisation and complete abstraction can be found. A second level component framework using fuzzy logic techniques is presented to illustrate how a significant degree of abstraction can be achieved, facilitating software portability, while accommodating the diversity of robotics.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121490810","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}

An evident and classical solution is the use of tele-operation and tele-robotics. If tele-operation helps to solve real and technical problems, it is still unable to assure appropriate remote diagnosis and maintenance. The use of virtual reality techniques with tele-operation can be the solution for effective remote maintenance and diagnosis. We show that inefficiency occurred with the use of tele-operation only in remote maintenance. We introduce our original new system where we use 2D-3D matching and virtual reality techniques with tele-operation to remotely collect machinery vibration data.
