    (Makina Teorisi Derneği, 2019) Uzunoğlu, Emre; Özkahya, Merve; Dede, Mehmet İsmet Can; Taner, Barış; Dede, Mehmet İsmet Can; Uzunoğlu, Emre; Kiper, Gökhan; Paksoy, Erhan; 01. Izmir Institute of Technology; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering
    Bu çalışmanın temel amacı endüstriyel uygulamalarda giderek sıkılıkla kullanılmaya başlanan yüksek ivmeli çalışan paralel robotların konumlama hassasiyetlerini artırmak üzere yapısal ve denetimsel iyileştirme yöntemlerinin araştırılmasıdır. Çalışma dâhilinde robot sistemlerinin hassasiyetini bozan geometrik olan ve olmayan faktörlerin etkilerinin en aza indirilmesi için yöntemler araştırılmıştır ve önerilmiştir. Bu yöntemler içerisinde geometrik olan faktörlerin tamamı, geometrik olmayan faktörlerden robot manipülatör direngenlikleri ve denetim hataları, ve bunlara ek olarak dengelenmemiş kütlelerden kaynaklanan hatalar konularında yapılan araştırmalar sunulmuştur. Ayrıca yöntemlerin araştırılması, kıyaslama amacı ile aynı işi yapmak üzere iki farklı yapıya sahip normal kısıtlı ve fazla kısıtlı iki mekanizma yapısı bu bildiri dâhilinde sunulmuştur.

    Conceptual Design of a 2-Dof Planar High-Speed Industrial Parallel Manipulator
    (Springer, 2019) Uzunoğlu, Emre; Paksoy, Erkan; Özkahya, Merve; Uzunoğlu, Emre; Paksoy, Erkan; Kiper, Gökhan; Taner, Barış; Dede, Mehmet İsmet Can; Dede, Mehmet İsmet Can; Kiper, Gökhan; 01. Izmir Institute of Technology; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering
    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.

    Applying Model Mediation Method To a Mobile Robot Bilateral Teleoperation System Experiencing Time Delays in Communication
    (Makina Teorisi Derneği, 2015) Taner, Barış; Dede, Mehmet İsmet Can; Dede, Mehmet İsmet Can; Uzunoğlu, Emre; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Teleoperation systems consist of two subsystems namely, the master and the slave. Master is used by the human operator to send commands to the slave to achieve a task. In bilateral teleoperation, the interaction forces acquired from the slave sub-system is sent to the master to increase the level of tele-presence. In this kind of a setting, data has to be transferred through a communication line in which package losses and time delays occur. Such deficiencies in the communication line results in stability problems in the system. In this paper, HIPHAD desktop haptic device as the master sub-system and an omni-directional mobile robot as the slave subsystem is used to develop an unlimited workspace teleoperation system. The system’s stability and tracking performance under a constant time delay is measured for direct teleoperation and when model mediation method is applied to ensure stability. The results of the tests are given and the conclusions are derived.
