Haptic devices are used to provide multi-modal data transfer between haptic users and computers in virtual reality applications. They enable humans to take force and tactile feedback from any virtual or remote objects. Haptic devices also facilitate the use of data collected from a real object in the virtual environment. Usage of the haptic devices increase more and more in industrial, educational and medical applications in parallel with development of virtual reality technology. As virtual reality technology requires interdisciplinary study with related to its application areas, it creates a lot of different specific working areas (Haptic interface design, freeform model, surgical operations in virtual environment etc.). Especially, some complex modifications which require hand-working can be performed with the system having great potential in medical applications (Brain surgery without error and operations which require great skill etc.). This is only one of the implementations of haptic devices in digital environment. Aim of this study is to design and manufacture a 7 DOF (degrees of freedom) haptic device which serves the mentioned application areas. All different haptic devices in literature have maximum 6 DOF. The designed 7 DOF haptic device has about 20% extra working space and more flexible working capability compared to the other haptic devices with the similar link lengths and joint limitations. This study is important in terms of the development of haptic devices in the world as well as spreading of haptic devices and its applications in Turkey.

Haptic dokunma hisli ve kuvvet geri beslemeli arayüz sistem tasarımı Konuseven, İlhan E.; Balkan, Raif Tuna; Koku, Buğra A.; Başer, Özgür; Bideci, Süleyman(2008) “Haptic” cihaz, kullanıcı ile bilgisayar arasında üç boyutlu veri transferi sağlayan bir cihazdır. Bu cihaz kullanıcıya sanal ortamdaki bir nesneyi görmenin yanında, bu sanal nesneye dokunma olanağı da sağlar. Aynı zamanda bu cihaz ile gerçek bir nesneden veriler alınarak bu verilerin sanal ortamda kullanımı da gerçekleştirilebilir. Günümüzde sanal gerçeklik teknolojisinin gelişimine paralel olarak “haptic” cihazlarının kullanımı, sanayi, eğitim ve tıp alanlarında gittikçe artmaktadır. Bu te...
Development of a material cutting model for haptic rendering applications Üner, Görkem; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2007) Haptic devices and haptic rendering is an important topic in the burgeoning field of virtual reality applications. In this thesis, I describe the design and implementation of a cutting force model integrating a haptic device, the PHANToM, with a high powered computer. My goal was to build a six degree of freedom force model to allow user to interact with three dimensional deformable objects. Methods for haptic rendering including graphical rendering, collision detection and force feedback are illustrate...
Design of a secondary packaging robotic system Şahin, Hakan; Balkan, Raif Tuna; Department of Mechanical Engineering (2005) The use of robotic systems in consumer goods industry has increased over recent years. However, food industry has not taken to the robotics technology with the same desire as in other industries due to technical and commercial reasons. Difficulties in matching human speed and flexibility, variable nature of food products, high production volume rates, lack of appropriate end-effectors, high initial investment rate of the so-called systems and low margins in food products are still blocking the range of use ...
Dokunsal kuvvet geri beslemeli cihaz tasarımı Başer, Özgür; Konukseven, Erhan İlhan; Koku, Ahmet Buğra (2005-11-01) Bu çalışmanın amacı, bilgisayar ile kullanıcı arasında üç boyutlu veri transferini sağlayabilecek dokunsal (haptic) kuvvet geri beslemeli bir cihazın geliştirilmesidir. Dokunsal cihazın geliştirilmesi sırasında, cihazın uç noktasına uygulanabilecek maksimum kuvvet ve moment ile birlikte çalışma hacmi ve rijidlik değerleri en iyilenmeye çalışılmış ve bu amaca uygun olacak şekilde tasarım parametrelerine karar verilmiştir. Sistemin düz kinematik çözümleri yapılarak tasarlanan dokunsal cihazın çalışma hacmi ol...
Performance improvement of a 3d reconstruction algorithm using single camera images Kılıç, Varlık; Platin, Bülent Emre; Department of Mechanical Engineering (2005) In this study, it is aimed to improve a set of image processing techniques used in a previously developed method for reconstructing 3D parameters of a secondary passive target using single camera images. This 3D reconstruction method was developed and implemented on a setup consisting of a digital camera, a computer, and a positioning unit. Some automatic target recognition techniques were also included in the method. The passive secondary target used is a circle with two internal spots. In order to achieve...
