    Conceptual Design of a 2-Dof Planar High-Speed Industrial Parallel Manipulator
    (Springer, 2019) Uzunoğlu, Emre; Özkahya, Merve; Paksoy, Erkan; Taner, Barış; Dede, Mehmet İsmet Can; Kiper, Gökhan
    This study focuses on conceptual design alternatives for a planar high-speed/high-precision manipulator in terms of mechanism structure, control strate-gy, and drive system selection. These concepts are investigated specifically for planar 5-bar based parallel linkages. An over-constrained 6-bar linkage with par-allelogram loops and its simply constrained version are selected for detailed de-sign. In addition, a model-based control strategy including a stiffness model is discussed for future studies. Alternative drive systems are evaluated. Finally a prototype is presented.

    Derivation of Input/Output Relationships for the Bennett 6r Linkages Based on the Method of Decomposition
    (Springer, 2014) Alizade, Rasim; Kiper, Gökhan; Dede, Mehmet İsmet Can; Uzunoğlu, Emre
    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 one of the common links. This paper presents the derivation of the input/output relationships for these mechanisms using the decomposition method. This method is based on writing the input/output equations for the two imaginary loops comprising the 6R mechanism and then eliminating the imaginary joint variable. It is found that the resulting input/output equations con-tain up to 4th power of trigonometric terms, such as cos4 θ.

    Trajectory Planning of Redundant Planar Mechanisms for Reducing Task Completion Duration
    (Springer, 2014) Uzunoğlu, Emre; Dede, Mehmet İsmet Can; Kiper, Gökhan; Mastar, Ercan; Sığırtmaç, Tayfun
    In the industry there is always a demand to shorten the task completion durations in order to maximize the efficiency of the operation. This work aims to provide a solution to minimize the task completion duration for planar tasks by in-troducing kinematic redundancy. An example setting of a redundant planar mech-anism is considered and an algorithm developed for resolving redundancy order to minimize task completion duration is discussed based on this mechanism.
