Conference Object Citation - WoS: 1Citation - Scopus: 1Modeling a Magneto-Rheological Fluid-Based Brake Via a Neural Network Method(Springer international Publishing Ag, 2022) Kucukoglu, Sefa Furkan; Dede, Mehmet Ismet Can; Dede, Mehmet İsmet Can; Küçükoğlu, Sefa Furkan; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyIdentifying the model of a magneto-rheological (MR) fluid-based brake is extremely important for designing and controlling a haptic device with hybrid actuation. Therefore, in this study, an Elman Recurrent Neural Network (ERNN) is designed to understand and model a characterization of an MR fluid-based rotational brake. Three important factors that affect the MR brake's performance are chosen as inputs: current, speed, and the first derivative of the input current. The proposed network is trained, and the performance of the network is tested with three different experimental scenarios. Then, the effect of these inputs on the system is investigated. According to the results, it can be said that the designed ERNN is a good candidate for modelling an MR brake.Article Analytical Dynamic Analysis of a Kinesthetic Haptic Device(Dokuz Eylül Üniversitesi, 2018) Dede, Mehmet İsmet Can; Maaroof, Omar Waleed Najm; Dede, Mehmet İsmet Can; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyA hybrid-structured kinesthetic haptic device based on an R-CUBE mechanism and a serial spherical wrist mechanism is considered in this article. This device is designed to simulate point-type contacts on the user. Hence, only three-dimensional forces are simulated to the user through the R-CUBE mechanism. This paper presents the quasi-static force analysis, gravity compensation calculations and dynamic analysis of the R-CUBE mechanism to serve for better understanding the capabilities of the mechanism and to be used in haptics controller development in the future studies. Making use of the derived dynamic equations, torque requirements from the actuators are examined for use in the haptic application scenarios.Conference Object Experimental Verification of Quasi-Static Equilibrium Analysis of a Haptic Device(Azerbaijan Committee of International Federation, 2017) Görgülü, İbrahimcan; Dede, Mehmet İsmet Can; Taner, Barış; Dede, Mehmet İsmet Can; Ceccarelli, Marco; Görgülü, İbrahimcan; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyHIPHAD v1.0 is a kinesthetic haptic device which was designed and manufactured in IzTech Robotics Laboratory. In this work, the quasi-static equilibrium analysis is carried out by including the gravitational effects. The calculations are verified through an experimental procedure and the results are presented to characterize the device performance.Conference Object Kinematic Analysis Validation and Calibration of a Haptic Interface(Springer Verlag, 2014) Dede, Mehmet İsmet Can; Taner, Barış; Dede, Mehmet İsmet Can; Ceccarelli, Marco; Bilgincan, Tunç; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyInitial calibration tests of a novel hybrid-structured kinesthetic haptic device based on an R-CUBE mechanism is presented in this paper. Experimental validation of the kinematics along with the experimental test set-up description is provided for the manufactured R-CUBE mechanism.
