    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.

    Design of a Teleoperation Scheme With a Wearable Master for Minimally Invasive Surgery
    (Springer, 2019) Ateş, Gizem; Majani, Ronny; Dede, Mehmet İsmet Can
    Minimally invasive surgery is increasingly being preferred over conventional surgery, however many problems still persist in longer surgeries such as pituitary surgeries, where surgeons are still required to hold an endoscope in their hand for prolonged periods of time. Many modern approaches have recently been proposed in literature to reduce the surgeon’s effort. In this paper we extended upon these previous attempts and presented a promising solution; a real time teleoperation scheme with 3 different modes of operation, composed of a wearable ring system that captures and transmits voluntary hand motions over a wireless connection to a slave system. Accordingly, this slave system processes the received data to generate velocity demands for the robot endoscope controller. Finally, the feasibility of the proposed modes of operation are demonstrated and compared by measuring their learning curve and effort by running a set of training simulations on human subjects.

    Unilateral Teleoperation Design for a Robotic Endoscopic Pituitary Surgery System
    (Springer, 2018) Dede, Mehmet İsmet Can; Maaroof, Omar Waleed Najm; Ateş, Gizem; Berker, Mustafa; Işıkay, İlkay; Hanalioğlu, Şahin
    The aim of this study is to develop a teleoperation system which will be used to support the endoscopic pituitary surgery procedures. The proposed system aims to enable the surgeon to operate with three different operation tools (one of them is the endoscope) simultaneously. By this way, it is expected that the productivity of the surgical operation will be improved and the duration of the operation will be shortened. In the proposed system, a main control unit that can be attached to any of the surgical tools that are used in the operation (other than the endoscope) will be developed to capture the motion of the surgeon’s hand motion as demanded by the surgeon, to process the captured motion and to send it to the robot that handles the endoscope. In this way, the endoscope will be directed simultaneously by the surgeon throughout the operation while he/she is using the other surgical tools with his/her two hands. In this paper, the study to determine the type and processing of information that is sent from the surgeon’s side to the endoscope robot is presented.

    Cerrahın Anlık Yönlendirilebildiği Robot Yardımlı Endoskop Kontrol Sistemi Mimarisi - Neuroboscope
    (Boğaziçi Üniversitesi, 2018) Dede, Mehmet İsmet Can; Kiper, Gökhan; Ayav, Tolga; Tatlıcıoğlu, Enver; Özdemirel, Barbaros; Maaroof, Omar; Ateş, Gizem; Berker, Mustafa; Işıkay, İlkay; Hanalioğlu, Şahin
    Bu bildiride ele alınan çalışmada endoskopik hipofiz cerrahisinde kullanılan optik-kamera sistemini, cerrahın anlık isteklerini takip ederek yönlendirilmesine izin verecek robotik sistem geliştirilmektedir. Cerrah kendisi ameliyat sahasında ameliyatı gerçekleştirirken robotu yönlendirmesi gerekmektedir. Bu gereksinim için geliştirilmekte olan özgün alt bileşenler ve toplam sistem mimarisi bildiri içinde tanıtılmıştır ve çalışmanın sonuçları benzer minimal invaziv ameliyatların robot destekli ameliyata dönüşmesine imkan verebilecektir. Bildiride sistemin gereksinimlerinin oluşturulması için yapılan testler anlatılmıştır. Üzerinde durulan sistem gereksinimlerinden birisi robotun çalışma alanı, diğeri ise cerrahın kullanım kolaylığı ile ilgilidir.

    Neuroboscope Sisteminin Model Tabanlı Sınaması
    (Otomatik Kontrol Türk Milli Komitesi, 2016) Uzun, Bengisu; Ayav, Tolga; Dede, Mehmet İsmet Can; Berker, Mustafa; Işıkay, İlkay; Hanalioğlu, Şahin; Özdemirel, Barbaros; Kiper, Gökhan; Tatlıcıoğlu, Enver; Maaroof, Omar W.; Işıtman, Oğulcan; Ateş, Gizem; Yaşır, Abdullah
    NeuRoboScope projesinde, endoskopik hipofiz cerrahisinde kullanılan optik-kamera sisteminin, cerrahın kullandığı cerrahi aletleri takip ederek yönlendirilmesini amaçlayan emniyet kritik bir sistemin tasarlanması amaçlanmıştır. Bu bildiri, sistem gereksinimleri üzerinden tüm sistemin modellenmesini ve oluşturulan bu modelin sınanmasını ele almaktadır. Böylece, tasarım evresinden önce tasarımın dayanağı olan sistem gereksinimlerinin doğrulanması hedeflenmiştir. Sistem bir zamanlı otomat ağı olarak modellenmiş ve UPPAAL model sınama aracı kullanılarak, sistemin başta emniyet kritik olmak üzere diğer önemli özellikleri sınanmıştır.
