An experimental test procedure for validation of stiffness model: A case study for R-CUBE parallel mechanism
(Springer, 2019)Haptic device manipulators are used for generating haptic feedback. This feedback is composed of force which is regulated with respect to motion information. Accurate generation of the feedback requires exact position ... -
Structural compliance effects on the accuracy and safety of a R-CUBE haptic device
(Springer, 2019)This paper addresses the contribution of structural compliance on stiffness and safety of a R-CUBE Haptic Device. Structural compliance is determined in several poses via FEM analysis and addressed by referring to local ... -
Geometrical analysis of a continuously variable transmission system designed for human-robot interfaces
(Elsevier, 2019)New robotic systems are placed out of their constrained workspaces in order to work alongside humans. Consequently, these applications call for robots monitoring and regulating physical human-robot interaction. These robots’ ... -
Low-power and low-cost stiffness-variable oesophageal tissue phantom
(Springer, 2017)Biological tissues are complex structures with changing mechanical properties depending on physiological or pathological factors. Thus they are extendible under normal conditions or stiff if they are subject to an inflammatory ... -
Reconfigurable deployable umbrella canopies
(Institute of Electrical and Electronics Engineers, 2018)The 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 ... -
The ARROWS Project: Robotic technologies for underwater archaeology
(Institute of Physics Publishing, 2018-06)The paper summarizes the main results achieved during the three-year European FP7 ARROWS project (ARchaeological RObot systems for the Worlds Seas). ARROWS concluded at the end of August 2015 and proposed to adapt and ... -
Wetting of chemically heterogeneous striped surfaces: Molecular dynamics simulations
(American Institute of Physics, 2018-06)Using molecular dynamics simulations, we thoroughly investigated the wetting behaviors of a chemically heterogeneous striped substrate patterned with two different wetting materials, face-centered cubic gold and face-centered ... -
Adaptive signal processing strategy for a wind farm system fault accommodation
(Institute of Electrical and Electronics Engineers, 2018-03)In order to enhance the 'sustainability' of offshore wind farms, thus skipping unplanned maintenance operations and costs, that can be important for offshore systems, the earlier management of faults represents the key ... -
The effect of cooling on mechanical and thermal stresses in vascular structures
(Yıldız Technical University, 2018-02)Here, we show how the vascular channel configuration and its shape affect the mechanical strength which is simultaneously subjected to heating and mechanical load. The material properties were defined as functions of ... -
