    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.

    Trajectory Planning for a Redundant Planar Laser-Cutting Machine With Macro-Micro Manipulation
    (IFToMM, 2015) Uzunoğlu, Emre; Dede, Mehmet İsmet Can; Kiper, Gökhan
    Kinematic redundancy in robots provide the control designer with infinite number of possibilities for improving the process for a selected target optimization criterion. A special type of kinematic redundancy is devised by using kinematically different two mechanisms with different advantages. In this case, the control design including the trajectory planning should be devised taking into account the distinct advantages of both mechanisms. In this work, a macro mechanism with larger workspace is used along with a micro mechanism that has higher dynamics and lower inertia. A trajectory planning algorithm integrated with the control structure making use of the previously defined advantages of both mechanisms is explained in this paper. A case study is provided to validate the developed algorithm.

    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.
