    Improved Usability of a Low-Cost 5-Dof Haptic Device for Robotic Teleoperation
    (Springer, 2019) Ateş, Gizem; Brunetti, Luca; Bonfè, Marcello
    The paper describes the design and application of a low-cost haptic device with five degrees of freedom (5-DOF), all of which are fully actuated for force/torque haptic display. The device is realized using two Novint Falcons, commercially available haptic devices with only translational DOF. The paper focus on the practical issues related to the use of such a haptic device as a robotic teleoperation master and provides solutions to improve its usability during an application inspired by surgical robotics, namely the teleoperated insertion of a needle into a soft tissue. Experiments demonstrate the usefulness of force feedback and virtual fixtures on both translation and orientation degrees of freedom. © 2019, CISM International Centre for Mechanical Sciences.

    Structural Compliance Effects on the Accuracy and Safety of a R-Cube Haptic Device
    (Springer Verlag, 2019) Carbone, Giuseppe; Acinapura, Antonio; Mundo, Domenico; Görgülü, İbrahimcan; Dede, Mehmet İsmet Can
    This paper addresses the contribution of structural compliance on stiffness and safety of a R-CUBE Haptic Device. Structural compliance is determined in several poses via FEM analysis and addressed by referring to local and global indices of performance. Results are also compared with evidences from experimental tests. Comparison of numerical and experimental data allows to identify and separate the contributions to the overall compliance that are due to the structural stiffness, and other contributions such as joint clearance, pose and loading conditions.

    Manipulator Design for a Haptic System With Improved Performance
    (Springer, 2021) Sekendiz, Veysel; Görgülü, İbrahimcan; Karabulut, Mehmet Görkem; Kiper, Gökhan; Dede, Mehmet İsmet Can
    This paper presents the work carried out to improve the design of an existing kinesthetic haptic device. The proposed improvement is designated for enhancing this device’s impedance width which is a common metric in performance evaluation of haptic devices. In this study, kinematic design optimization, static balancing, constructional design enhancement and actuation system design studies are presented.

    Experimental Evaluation of Actuation and Sensing Capabilities of a Haptic Device
    (Springer, 2019) Mobedi, Emir; Görgülü, İbrahimcan; Dede, Mehmet İsmet Can
    Haptic devices are used to increase the telepresence level by providing the sense of touch to the human operator. Simultaneously, they capture the targeted motion of the human operator to generate a motion demand for the teleoperated slave system. Considering a scenario where the slave system’s end-effector is handled by the human operator at the master side, which is attached to the haptic device, an ideal haptic interaction involves the feeling of only the end-effector dynamics and the accurate sensation of the end-effector pose. The performance of a haptic device is based on these two functionalities. In this paper, the experimental evaluation of the actuation and sensing capabilities of a haptic device, HIPHAD v1.0 kinesthetic haptic device, is presented.

    Analytical Dynamic Analysis of a Kinesthetic Haptic Device
    (Dokuz Eylül Üniversitesi, 2018) Dede, Mehmet İsmet Can; Maaroof, Omar Waleed Najm; Ceccarelli, Marco
    A 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.

    (Azerbaijan Committee of International Federation, 2017) Görgülü, İbrahimcan; Maaroof, Omar Waleed Najm; Taner, Barış; Dede, Mehmet İsmet Can; Ceccarelli, Marco
    HIPHAD 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.

    Image Processing Based Stiffness Mapping of a Haptic Device
    (Springer, 2017) Taner, Barış; Dede, Mehmet İsmet Can
    The widely accepted performance criteria of haptic devices, which are transparency and z-width, are affected by the stiffness characteristics of the haptic device’s mechanism. In addition indirect measurement of the handle pose of a haptic device is also affected by the stiffness characteristic. In this study, image processing techniques are used in the experimental setup to develop a stiffness map of a haptic device. The experimentally developed stiffness map is presented and the results are discussed by addressing future works.

    Development of an R-Cube Based General Purpose Haptic Device System
    (American Society of Mechanical Engineers, 2010) Bilgincan, Tunç; Dede, Mehmet İsmet Can
    A novel 6-Degree-of-Freedom (DoF) hybrid haptic device is presented in this paper. Hybrid mechanism consists of parallel kinematic structure, R-CUBE and a 3-DoF orientation mechanism. In our previous study, the original configuration of the R-CUBE mechanism was investigated. In this work, the original design of R-CUBE is reconfigured as a haptic mechanism and the final mechanism is reoriented in order to equally distribute the gravitational effects to all grounded actuators. Rotational motions of the end-effector are monitored through the 3-DoF orientation mechanism placed on the moving platform of the parallel platform. The design of this haptic device is suitable to reflect forces in translational motions, thus point-type of contact is available for this system. The designed device is manufactured utilizing various types of manufacturing processes, such as wire erosion, laser cutting, milling and turning. Finally manufactured mechanism is integrated with electromechanical components and tested for manipulability.
