Such operations are often performed through an incision port (a pivot point) on the patient's body. Since the end-effector (the handled surgical tool) move about the pivot point, the manipulator has to move about a remote center of motion. In this study, a 3-degrees-of-freedom parallel mechanism with 2R1T (R: rotation, T: translation) remote center of motion capability is presented for minimally invasive surgery applications. First, its kinematic structure is introduced. Then, its kinematic analysis is carried out by using a simplified kinematic model which consists of three intersecting planes. Then the dimensional design is done for the desired workspace and a simulation test is carried out to verify the kinematic formulations. Finally, the prototype of the final design is presented.Conference Object Citation - WoS: 1Citation - Scopus: 3Reconfigurable deployable umbrella canopies(Institute of Electrical and Electronics Engineers Inc., 2018) Jovichikj, R.; Yaşır, Abdullah; Kiper, GökhanThe kinematic design of reconfigurable deployable canopy mechanisms with radially distributed limbs are presented in this study. The mechanisms allow a compact form and are reconfigurable with several alternative deployed forms which can be in the form of a tent, a canopy or a form in between. Each limb of the canopy possesses at least two assembly modes which enables reconfigurability. The conditions for deployment and reconfiguration of the mechanism are derived. These conditions impose equality and inequality constraints for the link lengths of the mechanism. A parametric model of the mechanism is constructed in Excel for design and simulation purposes. Solid models and a prototype are presented as examples.
