Article Citation Count: 11Behavioural representation and simulation of design concepts for systematic conceptual design of mechatronic systems using Petri Nets(Taylor & Francis Ltd, 2014) Erden, Zühal; Erden, Zuhal; Mechatronics EngineeringThe systematic representation of design concepts is an important requirement for computational support during the conceptual design stage within the process of product development. Behavioural simulation of design concepts is used as a systematic representation framework, and behavioural representation is based on modelling and simulating the behaviour of a design artefact at the conceptual level to perform an overall function, leading to behaviour-based conceptual design. The behaviour-based conceptual design approach is critical for mechatronic systems since they require synergistic integration starting from the initial conceptual design phase. The present study is focused on behavioural representation and simulation of design concepts via discrete event system specification formalism and Petri Nets so as to contribute to systematic conceptual design in mechatronic systems. The paper introduces a representation framework for the behaviour-based conceptual design of mechatronic systems and its implementation on five selected case studies, among laboratory-level educational robots. In addition to Petri Net modelling and computer simulations, the implementation also includes physical simulations of the intended operational behaviours for educational robots on a distributed physical structure called the desktop design model'. In this paper, implementation on one of these case studies, namely the frog robot', is presented in detail.Article Citation Count: 1Development of Behavioural Modules for Mechatronic Product Families using the 3D Design Structure Matrix Approach(Ios Press, 2019) Erden, Zühal; Mechatronics EngineeringIncreased competition in the global market has forced companies to diversify their product ranges to meet the customers' changing needs and adopt product development strategies for "mass customization", which requires designing modular products. Product modularity is achieved via platform-based systems, in which various combinations of different modules are assembled within a common platform. In the literature, there is a considerable amount of research on modularity for mechanical products. Yet, research on modularity of smart systems, such as mechatronic products, is quite limited. Therefore, the objective of this research is to develop fundamental behavioural modules to facilitate the systematic design of platform-based mechatronic product families for mass customization. Being developed using the state-event model of mechatronic systems at an early design stage, these modules enable a behavioural adaptation of smart systems through a systematic formal structure. In this study, fundamental mechatronic behaviour modules are developed using a modified form of Design Structure Matrix (DSM) existing in the literature. DSM is adopted to mechatronic systems as a 3D matrix, which includes sensorial, motoric and cognitive behaviours. Symbolic representations of mechatronic behaviour modules are generated and used for describing robot tasks. The mechatronic behaviour modules developed in this study are implemented on a demonstrative task-based robot family model composed of guide robots for museums and shopping malls, a guard robot, a house-cleaning robot and companion robots for children, the elderly and pets.Article Citation Count: 0A Novel Approach to Systematic Development of Social Robot Product Families(Springer, 2022) Erden, Zühal; Erden, Zuhal; Mechatronics EngineeringIn this paper, behavioural modules for social robots are developed by using the 3D Design Structure Matrix (DSM) model. Behavioural modules are the building blocks for the systematic design of social robot families, which are composed of personalized social robots, to satisfy the diverse needs of individuals or small groups. The 3D DSM is independent of any physical solution principle and is based on 3 different behavioural elements among robots, namely 'perception', 'cognition' and 'motoric action'. In this study, the data for these elements are extracted from 45 different social robots existing in the literature. Sixteen behavioural modules are developed by defining the mutual interactions among these three types of behavioural elements. Among them, 6 sample modules are designed and manufactured in the laboratory. A model social family of two robots which uses different combinations of these 6 modules is developed for technology demonstration. This study is a first attempt to establish a behaviour, modularity-oriented and physical solution-independent infrastructure in the systematic conceptual design of personalized social robots for alternative purposes; hence, a starting point for future research toward further integration of social robots into everyday life.Article Citation Count: 2A team-oriented course development experience in distance education for multidisciplinary engineering design(Wiley, 2022) Erden, Zühal; Erden, Zuhal; Turhan, Cihan; Say, Bilge; Energy Systems Engineering; Mechatronics Engineering; Software EngineeringBased on the multidisciplinary needs of today's complex and innovative technology, accreditation bodies of engineering demand proof of multidisciplinary teamwork in undergraduate engineering curricula. This article reports the design and conduct of a Multidisciplinary Engineering Design (MED) course initiated as a result of accreditation process requirements. The course, which consists of multidisciplinary lectures, practice sessions, and various phases of a multidisciplinary team project, was conducted online because of the COVID-19 pandemic by a multidisciplinary team of instructors using multiple software tools to enhance collaboration. In general, the course outcomes were satisfied under the current design, and several points for further improvement and elaboration were collected via quantitative and qualitative evaluations. Accordingly, the results show that the project-based and team-based MED course, in terms of multidisciplinary course management and its outcomes, can benefit from the use of software tools in creating a multidisciplinary team in distance education by means of enhanced cooperation and motivation among the participants.
