Article Citation - Scopus: 2Effects of Earthquake Motion on Mechanism Operation: an Experimental Approach(Levrotto and Bella, 2015) Selvi, Ö.; Selvi, Özgün; Ceccarelli, M.; Aytar, E.B.; Makine MühendisliğiThis paper presents an experimental characterization of the effects of earthquakes on the operation of mechanical systems with the help of CaPaMan (Cassino Parallel Manipulator), which is a 3 DOF robot that can fairly well simulate 3D earthquake motion. The sensitivity of operation characteristics of machinery to earthquake disturbance is identified and characterized through experimental tests. Experimental tests have been carried out by using a slider-crank linkage, a small car model, and LARM Hand as test-bed mechanisms that have been sensored with proper acceleration or force sensors. Results are reported and discussed to describe the effects of earthquake motion on the characteristics of mechanism operation as a service application of the robotic CaPaMan system.Conference Object Citation - Scopus: 5Design and Optimization of a Walking Over-Constrained Mechanism(Springer Science and Business Media B.V., 2019) Ceccarelli, M.; Selvi, Ö.In this paper, a walking overconstrained mechanism with one DoF is presented. Firstly, its dimensional parameters and geometry are shown and a step profile which is wanted to be followed by end point of the walking mechanism is proposed. Kinematic equations of the walking mechanism are extracted to use them later as constraints for Firefly Algorithm. Algorithm is run in get the optimized dimensional parameters to provide the desired step profile. Results are presented. © 2019, Springer Nature Switzerland AG.Conference Object Citation - WoS: 1Citation - Scopus: 3Redesign and Construction of a Low-Cost Capaman Prototype(Springer international Publishing Ag, 2019) Karaahmet, S. B.; Selvi, O.; Cafolla, D.; Ceccarelli, M.; Arslan, O.In this paper a redesign solution for CaPaMan structure is presented to build a scaled low-cost prototype with market components and 3D printed parts. A CAD design is worked out to define 3D printing manufacturing for link parts and to adjust the mechanical design and its assembly after performance evaluation ensuring characteristic features of CaPaMan operation. A small-size prototype is built and tested with satisfactory functioning.
