Conference Object Citation - WoS: 3Citation - Scopus: 4Unilateral 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, ŞahinThe 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.Book Part Citation - WoS: 3Citation - Scopus: 5Physical Human-Robot Interaction: Increasing Safety by Robot Arm’s Posture Optimization(Springer, 2016) Maaroof, Omar Waleed Najm; Dede, Mehmet İsmet CanTo have robot manipulators working alongside with humans is a necessity in service robots. Obviously, in these robotics applications, human safety has precedence over precision and repeatability, which are the most important qualification of the conventional industrial manipulators. The safety measures can be taken either in the hardware or in the software or in both. This work by using a redundant manipulator aims at providing a safety measure through controlling the self-motion of the manipulator. The self-motion of the manipulator is controlled to change the posture of the manipulator to minimize or maximize the forces it can exert along a given direction. In this way, by knowing the location of the human or a delicate piece that it should not harm, manipulator’s posture is optimized to exert the minimum amount of forces during an unexpected collision. The control algorithm for this objective is described in this paper and it is evaluated through simulation tests on a redundant lightweight robot manipulator.
