Bioinspired Conceptual Design (bicd): Conceptual Design of a Grasshopper-Like Jumping Mechanism as a Case Study
(2011) Eroglu,A.K.; Erden,Z.; Erden,A.; Department of Mechatronics Engineering; Mechatronics Engineering
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.
Developing an Analysis Process for Biological Systems To Design Biorobots - a Case Study of Human Hand Gripping Motion
(2013) Eroǧlu,A.K.; Erden,Z.; Erden,A.; Mechatronics Engineering; Department of Mechatronics Engineering
The fundamental reasoning behind the use of bioinspired design (BID) is to increase creativity (novelty and usefulness) and innovation in engineering. Within the context of BID, development of systematic process for analyzing biological systems and transferring knowledge, which is obtained from the analysis of biological systems, into engineering is compulsory. This paper presents developing a process for the analysis of biological systems for design of biorobots. Preparing, collecting, and organizing are the main steps of this process and applied in a case study which involves gripping motion of a human hand. An experimental set-up with a high-speed camera is constructed to obtain the components of knowledge: morphology, function and behavior. This knowledge will be later used to design a wearable hand in prospective projects.
Petri Net Modeling and Simulation of Walking Behaviour for Design of a Bioinspired Robot Dog
(SciTePress, 2016) Erden,Z.; Araz,M.; Mechatronics Engineering
Research in behavior-based design faces many challenges regarding the AIDS in conceptual design of biorobots, representation of a biological system,s behavior in a well formed modeling tool and therefore providing systematic transformation of this behavior into robot design. This paper reports a research that focuses on the development of a Petri Net model to represent a biological system,s behavior. The model is based on real time data collected from an experiment in which a dog is walking on a treadmill with a speed of 1km/h. The model has the ability of simulating the real time rhythm of dog's walking behavior utilizing colors and numbers as well as the step-by-step simulation. The aim is to observe the behavior of a walking dog in time domain as an early stage of conceptual design of a bioinspired robot dog. Main challenge is to develop a methodology to guide designer towards more creative designs based on bioinspired design ideas. The presented work is an early attempt to initiate a systematic approach towards the stated goal. © Copyright 2016 by SCITEPRESS - Science and Technology Publications, Lda. All rights reserved.

Representation of the Operational Behaviour of an Educational Robot at Conceptual Design Using Petri Nets
(2010) Erden,Z.; Mechatronics Engineering
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 design of multidisciplinary products such as mechatronic systems. During the conceptual design of such systems, intended "operational behavior" 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 behaviors. 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. © 2010 by ASME.
Studying the Impact of the “undergraduate Research Projects” Course in Mechatronics Engineering on the Professional Career Development of Engineers
(Rajarambapu Institute Of Technology, 2024) Erden,Z.; Mechatronics Engineering
Undergraduate research (UR) in engineering education is an important active learning strategy, and it is widely used through various implementation styles. Several studies have been conducted to assess the contribution of UR experience in the career path of alumni from an academic point of view and based on graduate studies. This paper is focused on the assessment of UR experience gained through a two-semester long “Undergraduate Research Projects” course sequence, on the professional career of mechatronics engineering alumni. The results of a survey-based investigation show that such UR experience is considered beneficial by the alumni in three main aspects: employment, entrepreneurship and the effect of the obtained knowledge and skills on the professional career. The feedback from the alumni has revealed that this experience contributes significantly to the development of their research abilities. In addition, many graduates emphasized that the UR experience is beneficial for employment as well as for their academic and professional development. The suggestions from the alumni concerning collaboration with the industry, course methodology, and selection of project topics form a basis for systematic UR model development by faculties in the future. © 2024, Rajarambapu Institute Of Technology.

Systematic Generation of a 3d Dsm by Extracting Social Robot Behaviors From Literature
(Cambridge University Press, 2019) Ozer,I.; Erden,Z.; Mechatronics Engineering
Social robots are in direct communication and interaction with people, thus it is important to design these robots for different needs of individuals or small groups. This has revealed the need to develop design methods for personalized or mass-individualized social robots, which are expected to respond to many different needs of people today and in the future. In this paper, a previously developed 3D DSM model is implemented in the systematic conceptual design of social robot families. The model is independent of any physical elements and based on behavioural elements as perception, cognition and motoric action. The data regarding 45 different social robots from 80 articles in the literature is used to identify these three behaviours of the existing social robots and the mutual relationships among these different behaviours are defined in order to develop a 3D DSM structure to be used as a basis for designing social robot families. The resulting novel 3D DSM is a general-purpose, basic model that can be used to identify behavioural modules to design social robot families. © 2019 Design Society. All rights reserved.
