Behavioural Representation and Simulation of Design Concepts for Systematic Conceptual Design of Mechatronic Systems Using Petri Nets
(Taylor & Francis Ltd, 2014) Araz, Macit; Erden, Zuhal
The 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.

BIOINSPIRED CONCEPTUAL DESIGN (BICD): CONCEPTUAL DESIGN OF A GRASSHOPPER-LIKE JUMPING MECHANISM AS A CASE STUDY
(design Soc, 2011) Eroglu, Aylin Konez; Erden, Zuhal; Erden, Abdulkadir
The evolution process of nature creates highly effective, power efficient, and perfectly structured biological systems. These excellent systems provide an inexhaustible source for engineers and scientists who desire to inspire ideas, processes, structures, functions, and behaviors from biological domain and implement them into engineering domain. This approach is called "Bioinspired" and challenging for engineers. However, some problems of the practical approaches are observed. One of the problems is "ad hoc" nature of the process. Each bioinspired design product has resulted in a differing design process and a generalization was not possible. Another problem rises due to the terminology difference between engineers and biologists. To overcome these problems, a need for a systematic bioinspired design (BID) process was realized in early 2000s and since then, considerable research on the BID methodology has been progressed. Within the context of BID, this paper introduces a new approach on bioinspired conceptual design (BICD) procedure for hybrid bioinspired robots which can be inspired from multiple biological systems. An illustrative case study is given in the paper.

Biological System Analysis in Bioinspired Conceptual Design (bicd) for Bioinspired Robots
(Romanian Soc Control Tech informatics, 2011) Eroglu, Aylin Konez; Eroğlu, Aylin Konez; Erden, Zuhal; Erden, Zühal; Erden, Abdulkadir; Erden, Abdulkadir; Eroğlu, Aylin Konez; Erden, Zühal; Erden, Abdulkadir; Department of Mechatronics Engineering; Department of Mechatronics Engineering; Mechatronics Engineering; Mechatronics Engineering; Department of Mechatronics Engineering; Mechatronics Engineering
Bioinspired design (BID) provides a systematic way for bioinspired applications. Although several BID approaches as well as some tools and databases are available in the literature, the studies on BID are still challenging for designers and/or engineers because of limitations of current BID approaches. There are mainly two directions related with these limitations. One of them is the representation of knowledge on biological systems and the second is the problem of transforming this knowledge into engineering domain. These limitations expose two questions; firstly, "What knowledge is required to describe biological systems?" and "How this knowledge is represented?" and secondly, "How this knowledge is transformed into the engineering domain?". This paper presents a study which aims to answer the first question about knowledge required to represent biological systems. This knowledge is obtained during "Analysis of Biological Systems" stage of a new suggested bioinspired conceptual design (BICD) procedure.

Development of Behavioural Modules for Mechatronic Product Families Using the 3d Design Structure Matrix Approach
(Ios Press, 2019) Erden, Zuhal
Increased 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.

A Novel Approach To Systematic Development of Social Robot Product Families
(Springer, 2022) Ozer, Ilayda; Erden, Zuhal
In 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.

Representation of the Operational Behaviour of an Educational Robot at Conceptual Design Using Petri Nets
(Amer Soc Mechanical Engineers, 2010) Erden, Zuhal
Increasing demand for computational support at conceptual design makes behavioural modeling a challenging area for design research. This is mainly because a behavioural model of a nonexistent design artifact at conceptual level is the basis for behavioural simulation and resulting computational design support. Behavioural models are particularly important for top-down of multidisciplinary products such as mechatronic systems. During the conceptual design of such systems, intended "operational behaviour" of the artifact is described without any physical realization. As design stages become more concrete, operational behaviour can be refined so as to represent well defined mathematical descriptions of corresponding physical behaviours. In this study, a model for representing the intended operational behaviour of a nonexistent educational robot, namely a rabbit robot, is presented for conceptual design. The operational behaviour of the robot is defined as composed of states and state transitions independent of any physical embodiment. Discrete Event System Specification (DEVS) and Petri Net formalism are used for the model. This representational model is the first step towards the development of a virtual prototype for the operational behaviour of an educational robot.

State-Based Conceptual Design in Mechatronics Via Petri Nets: a Case Study for an Educational Robot
(Romanian Soc Control Tech informatics, 2011) Erden, Zuhal; Mechatronics Engineering
Use of state-based models to represent artifact behaviors at conceptual design is a challenging area for design research. Conceptual design of mechatronic systems needs a multi-domain approach in which the "logical behavior" of a mechatronic design artifact is described without any physical realization. This paper presents a case study on state-based representation for the intended behavior of a non-existent robot at early conceptual level. The behavior is defined through a demonstrative scenario and represented as states and state transitions independent of any physical embodiment. Discrete Event System Specification (DEVS) and Petri Net formalism are used for the model. This representational model is first step towards the development of a virtual prototype for the logical behavior of robot design.

Based 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.

What To Consider at the Development of Educational Programs and Courses About Next-Generation Cyber-Physical Systems?
(Asme, 2024) Horvath, Imre; Erden, Zuhal
We live in an age in which new things are emerging faster than their deep understanding. This statement, in particular, applies to doing research and educating university students concerning next-generation cyber-physical systems (NG-CPSs). The fast evolution of this system paradigm would have expected a rapid and comprehensive paradigmatic change in research and education concerning this family of systems. However, this has not happened yet. Seeking a sufficient explanation, this paper reviews the current literature and attempts to cast light on the most significant recent developments in the field of NG-CPSs. The main assumptions of the authors are that research and education should appear in harmony in academic knowledge acquisition and distribution processes and that the academic education of NG-CPSs should be organized and conducted according to a defendable future vision. Combining the results of a broadly based study of the literature with prognostic critical thinking and personal experiences, this review-based position paper first discusses the current socio-techno-scientific environment, the involved stakeholders, and the demands and two approaches of truly systems-oriented education. Then, it concentrates on (i) the recognized limitations of mono- and interdisciplinary research, (ii) supradisciplinary organization of research, and (iii) transdisciplinary knowledge generation for NG-CPSs. As main contributions, the paper (i) identifies and analyzes the latest theoretical, engineering, and technological developments, (ii) reveals the major trends and their presumably significant implications, and (iii) presents several thought-provoking findings and makes propositions about the desirable actions.
