A closed-form solution of spatial sliders for rigid-body guidance
Huang, Chintien; Huang, Weiche; Kiper, Gökhan (Springer, 2013-10-16)This paper presents a closed-form solution to the four-position synthesis problem by using a spatial slider, which is a spatial dyad of two perpendicularly intersected cylindrical joints. We utilize the dialytic elimination ... -
Computing the safe working zone of a 3-RRS parallel manipulator
Patel, Dhruvesh; Kalla, Rohit; Tetik, Halil; Kiper, Gökhan; Bandyopadhyay, Sandipan (Springer, 2017)Determination of the safe working zone (SWZ) of a parallel manipulator is a one-time computational task with several permanent benefits. As this subspace of the workspace of the manipulator is free of both the loss- and ... -
Conceptual Design of a 2-DoF Planar High-Speed Industrial Parallel Manipulator
Uzunoğlu E.; Özkahya M.; Paksoy E.; Taner B.; Can Dede M.I.; Kiper, Gökhan (Springer Netherlands, 2020)This study focuses on conceptual design alternatives for a planar high-speed/high-precision manipulator in terms of mechanism structure, control strategy, and drive system selection. These concepts are investigated ... -
Control of mechanical joints that have joint clearance
Gündüzalp, Gün (Izmir Institute of Technology, 2015-03)Joint clearance is a defect that is present in all mechanical joints in every mechanism. Joint clearances for revolute joints result from the relatively small difference between the dimensions of diameters of two concentric ... -
A critical review of unpowered performance metrics of impedance-type haptic devices
Görgülü, İbrahimcan; Kiper, Gökhan; Dede, Mehmet İsmet Can (Springer, 2019)A kinesthetic haptic device’s performance relies on unpowered, powered and controlled system characteristics. In this paper, a critical review is carried out for the well-known metrics for kinematics, stiffness and dynamic ... -
Derivation of input/output relationships for the Bennett 6R linkages based on the method of decomposition
Alizade, Rasim; Kiper, Gökhan; Dede, Mehmet İsmet Can; Uzunoğlu, Emre (Springer, 2014)The Bennett overconstrained 6R linkages are the double-planar, the double-spherical and the plano-spherical 6R linkages. These mechanisms are obtained by combining simple planar and/or spher-ical mechanisms and then removing ... -
