(2022). Design Praxis with the Kingfisher and Bacteria; The River as Place for Post Human-Centered Design learning. Design for All Institute of India, 17(6), 51-64. , 2022.06, [URL], The aim of this paper is to unpack and question the anthropocentricity of our interactions with public place and how we might be able to foster learning to overcome dominant modes of praxis. The article focuses on rivers as an example of opportune places for Post Human-Centered Design of informal education and decentralized co-design of culture. The surrounding literature are presented, leading to pathways to radical inclusion of more-than-human concerns and discusses the interactions that can emerge through case study on the Naka river in Fukuoka, Japan. Keywords: More-than-human, Non-human, Inclusion, Learning, Anthropocene, Post Human-Centered Design, River, Personhood.. |

Social Implementation of Design Workshops Output-Research on factors leading to a project successful introduction and application: Social Implementation of Design Workshops Output-Research on factors leading to a project successful introduction and application. In Proceedings of the 6th International Conference for Design Education Researchers Learn x Design 2021: Proceedings of the 6th International Conference for Design Education Researchers Learn x Design 2021 (pp. 910) https://doi.org/10.21606/drs_lxd2021.05.157, 2021.12, [URL], This paper is a summary of the analyzed experiences collected from ‘social implementation projects’ which started as participatory design workshops. Since there is very little research done on social implementation methods based on these kinds of workshops outcome, this study aims to review the projects that were successfully implemented and clarify the factors leading to their successful social realization. Using a qualitative approach, archival data was reviewed and project leaders were interviewed, which shed light over the characteristics necessary for the successful enactment of the ideas sprung from the workshops. This study shows there are four essential attributes that a workshop output must posses in order to be socially implemented: A stake-holding oriented system, a collaborative environment, a strong bond between local issues and external resources, and a solid foundation of flexible design thinking methods.. |

To solve these global issues, new mechanisms need to be created. In the creation of new value, a lot of attention is being paid to design. This is evident from the fact that many workshops are conducted using the ‘design process ‘. The design process is the process of finding a solution to a problem or issue that has arisen, using a design approach and method of 5 stages: (1) understanding, (2) problem identification, (3) idea development, (4) testing (prototype production), and (5) proposal presentation. Due to the widespread of the new coronavirus that has threatened people around the world, online workshops have become very common. In addition, digital communication tools such as Zoom and Miro have been widely used for online workshops. Face-to-face workshops and online workshops have very different communication methods. For the online workshop, digital tools can create communication barriers that can affect the output of the workshop. Even though there are a lot of online workshops based on the design process, conducted in various location, there has been no research focusing on communication methods. The purpose of this study is to propose a method of communication for online participatory workshops that use the design process. The differences in communication methods between face-to-face and online participatory workshops are studied to identify factors that inhibit communication in online workshops that could not occur in face-to-face workshops, and the differences in output and quality are also clarified. This study is based on the SMRC model proposed by David Berlo, and this study was conducted using a quantitative and qualitative approach. The object of the study was the participants of the face-to-face workshops from 2012 to 2019 and online workshops in 2020. Video recording of the participants in the workshops and questionnaires for participants were conducted. The response of the participants in terms of their body language and conversation and the quality of prototypes were noted for each stage in the design process. Then the data was organized to identify the communication issues faced in the online workshops and the difference in the output and its quality. This study is a proposal for design workshop instructors. Based on the findings, a new communication method is proposed to solve the problems identified. The proposed communication method enable online participatory workshops with diverse participants to be conducted with increased chances of success from a communicative perspective. Thus, enabling the workshop organizers who focus on elements of the workshop that are more critical for the qualitative outcome of these. In the dawn of massive vaccination programs currently under implementation, the world will eventually regain some semblance of similarity analogous to a pre-pandemic condition. However, even with a ‘solution’ at hand, online activities, including workshops, are mostly expected to increase and diversify, the significance of this research is a direct contribution to this new era.. |

DS 93: Proceedings of the 20th International Conference on Engineering and Product Design Education (E&PDE 2018), Dyson School of Engineering, Imperial College, London. 6th-7th September 2018. 2018., DS 93: Proceedings of the 20th International Conference on Engineering and Product Design Education (E&PDE 2018), Dyson School of Engineering, Imperial College, London. 6th-7th September 2018. 2018., DS93, 224-229, 2018.09, [URL], The focus of this paper is disruptive innovation, created through processes of hybridisation. For the purpose of this study, the term ‘hybridisation’ refers to the blending of design practices that strongly reflect key societal and behavioural aspects of the two or more respective original cultures. The research addresses the role of hybridised design practices in tackling documented weaknesses in the innovation industry in Japan and in the UK. Re-mix is a collaborative research project between the Royal College of Art (RCA) and Kyushu University (KU). A series of experimental short projects explored the mutual impact of combining two design practices embodying the regional cultures of the involved institutions. The contrasting design practices embrace the full spectrum of innovation: from incremental innovation (KU) through inclusive approaches with close coordination with participatory communities, aiming at solid improvements, to radical innovation (RCA) fostered by diversity, ambiguity, improvisation, conflict, high-risk strategies and acceptance of failure. Two projects were undertaken in London and Fukuoka, which were used as fields for mutual observation, and mapping of practices during and after the end of each phase of the project. This revealed opposing factors in innovation culture and process, as documented in the literature. Initial findings have shown strong potential in this approach, as a method to trigger a novel hybrid process. Based on the observation of team performance, it has been postulated that such a process may be characterised by non hierarchical structure, as well as effectively merging a risk taking culture with specialist knowledge.. |

The aim is to successfully follow industry standard test cycles used for emissions testing and produce repeatable results. Success will be measured by not exceeding the limits set for human drivers for a successful test. The design of this robotic driver is unique; it uses a single linear motion to actuate the brake and throttle pedals controlled by two cascaded PID controllers (vehicle speed and pedal actuator position). A full SIMULINK model has been created and used for simultaion and rapid control prototyping using dSPACE. The system has been developed and tested from simulation through to actual dynamometer testing. Test results show that by time-shifting the drive cycle 2 seconds forward, the robotic driver successfully adhered to the ADR 37/01 standard, and produced repeatable results. Further development is needed to improve the performance and overcome current system limitations such as motor saturation and accelerator pedal stick-slip.. |

Calius, A thin membrane artificial muscle rotary motor, Applied Physics A: Solids and Surfaces, 10.1007/s00339-009-5434-5, 98, 1, 75-83, 2010.01, Desirable rotary motor attributes for robotics include the ability to develop high torque in a low mass body and to generate peak power at low rotational speeds. Electro-active polymer artificial muscles offer promise as actuator elements for robotic motors. A promising artificial muscle technology for use as a driving mechanism for rotary motion is the dielectric elastomer actuator (DEA). We present a membrane DEA motor in which phased actuation of electroded sectors of the motor membrane impart orbital motion to a central drive that turns a rotor. The motor is inherently scalable, flexible, flat, silent in operation, amenable to deposition-based manufacturing approaches, and uses relatively inexpensive materials. As a membrane it can also form part of the skin of a robot. We have investigated the torque and power of stacked membrane layers. Specific power and torque ratios when calculated∈ using∈active∈membrane∈mass∈only∈were∈20.8 W/kg and 4.1 Nm/kg, respectively. These numbers compare favorably with a commercially available stepper motor. Multi-membrane fabrication substantially boosts torque and power and increases the active mass of membrane relative to supporting framework. Through finite element modeling, we show the mechanisms governing the maximum torque the device can generate and how the motor can be improved.. |
| 9. | Benjamin M. O'Brien, Emilio P. Calius, Tokushu Inamura, Sheng Q. Xie, Iain A. Anderson, Dielectric elastomer switches for smart artificial muscles, Applied Physics A: Solids and Surfaces, 10.1007/s00339-010-5857-z, 100, 2, 385-389, 2010.08, Some of the most exciting possibilities for dielectric elastomer artificial muscles consist of biologically inspired networks of smart actuators working towards common goals. However, the creation of these networks will only be realised once intelligence and feedback can be fully distributed throughout an artificial muscle device. Here we show that dielectric elastomer artificial muscles can be built with intrinsic sensor, control, and driver circuitry, bringing them closer in capability to their natural analogues. This was achieved by exploiting the piezoresistive behaviour of the actuator's highly compliant electrodes using what we have called the dielectric elastomer switch. We developed suitable switching material using carbon loaded silicone grease and experimentally demonstrated the primitives required for self-sensing actuators and digital computation, namely compliant electromechanical NAND gates and oscillator circuits. We anticipate that dielectric elastomer switches will reduce the need for bulky and rigid external circuitry as well as provide the simple distributed intelligence required for soft, biologically inspired networks of actuators. Examples include many-degree-of-freedom robotic hearts, intestines, and manipulators; wearable assistive devices; smart sensor skins and fabrics; and ultimately new types of artificial muscle embedded, electromechanical computers.. |

O'Brien, Thomas McKay, Todd Gisby, A soft and dexterous motor, Applied Physics Letters, 10.1063/1.3565195, 98, 12, 2011.03, We present a soft, bearing-free artificial muscle motor that cannot only turn a shaft but also grip and reposition it through a flexible gear. The bearing-free operation provides a foundation for low complexity soft machines, with multiple degree-of-freedom actuation, that can act simultaneously as motors and manipulators. The mechanism also enables an artificial muscle controlled gear change. Future work will include self-sensing feedback for precision, multidegree-of-freedom operation.. |

Anderson, Tony Chun Hin Tse, Tokushu Inamura, Benjamin O'Brien, Thomas McKay, Todd Gisby, Flexidrive A soft artificial muscle motor, Electroactive Polymer Actuators and Devices (EAPAD) 2011 Electroactive Polymer Actuators and Devices (EAPAD) 2011, 10.1117/12.880714, 7976, 2011.05, We use our thumbs and forefingers to rotate an object such as a control knob on a stereo system by moving our finger relative to our thumb. Motion is imparted without sliding and in a precise manner. In this paper we demonstrate how an artificial muscle membrane can be used to mimic this action. This is achieved by embedding a soft gear within the membrane. Deformation of the membrane results in deformation of the polymer gear and this can be used for motor actuation by rotating the shaft. The soft motors were fabricated from 3M VHB4905 membranes 0.5mm thick that were pre-stretched equibiaxially to a final thickness of 31 μm. Each membrane had polymer acrylic soft gears inserted at the center. Sectors of each membrane (60° sector) were painted on both sides with conducting carbon grease leaving gaps between adjoining sectors to avoid arcing between them. Each sector was electrically connected to a power supply electrode on the rigid acrylic frame via narrow avenues of carbon-grease. The motors were supported in rigid acrylic frames aligned concentrically. A flexible shaft was inserted through both gears. Membranes were charged using a step wave PWM voltage signal delivered using a Biomimetics Lab EAP Control unit. Both membrane viscoelasticity and the resisting torque on the shaft influence motor speed by changing the effective circumference of the flexible gear.. |
