Abstract: One of the ways to advance toward a more regenerative construction industry is by developing a biodegradable, waste-based alternative building material. Building upon the previous research on dry-stacking interlocking modular blocks made of three kinds of organic waste (cotton, coffee chaff, and sawdust+mycelium), this study focuses on designing Mycelium-Based Composite (MBC) B-Blocks. By developing this reusable and adaptable MBC block design, this study addresses the current trend of using MBC solely as a temporary building material. The primary objectives are to refine the B-Blocks module design, improve the proportion to increase configuration possibilities for wall components, and explore different approaches for wall installations using these blocks. The research was conducted with students from the Innovative Digital Technology elective class in the Architecture Department at Universitas Pelita Harapan (UPH). The methodology involved exploring digital tectonics through parametric associative modeling, creating a mock-up model using parametric associative modeling and digital fabrication machinery, and producing 1:1 prototypes of the modules in collaboration with MYCL-Mycotech Lab.

Abstract: The article describes design of a drive module of a modular mobile chassis. This chassis was developed at the Department of Robotics, Faculty of Mechanical Engineering, VŠB-Technical University of Ostrava, as a part of the student grant competition “Research and development of modular robotic systems.” The article describes variants and the final mechanical construction of the drive module and also the structural analysis of this module according to the possible positioning in the whole modular system. The obtained results and possible ways of additional future development and modifications of the module are summarized in the conclusion.

Abstract: Vibration testing is used by introduction of a force function into system, usually with the use of a shaker or vibration testing machine. These induced vibrations, aid in the laboratory or production floor for a variety of things, proof of concept, standard assessment, fatigue testing, and evaluating performance. Electrodynamic shakers are well suited for most vibration tests and offer several advantages over alternative approaches. Resonance searches involve sine sweep to obtain a transfer function for evaluation of resonance characteristics, usually by a crank mechanism. Fatigue testing is an expensive and long term test, not being the most accurate one, due to the fact that the functioning of any machine is not repetitive nor reproducible regarding vibrations.Random vibration testing better represent real world data by providing statistical confidence with random time data that has an average targeted frequency content and amplitude over the duration of the test. By controlling amplitude and frequency, test data can be correlated to real world data sets.Throughout this paper we present the outlines for the design of a modular fatigue testing machine with pseudorandom vibrations. Due to the nature of the modular approach for our equipment, the rig can be appropriately configured to perform multiple laboratory tests.

Abstract: In view of solar arrays applied in large-scale stratospheric airship, modular thinking was proposed by reasonable decomposition of solar array to design composite maximum power point tracking (MPPT) controller where the input and output are both in parallel, which ensures maximized solar energy output on a limited area. And each solar array sub-model was equipped with independent MPPT controller to control power tracking separately. Then, the solar array composed of three sub-models was used for simulation and its result indicates that MPPT controller of each sub-model can track the power quickly, and the output power can reach 93% of maximum input power when the efficiency loss of converter in reality is not considered . So, the model constructed in this paper can be used to optimize the design and analyze output characteristics quantitatively for the large-scale stratospheric airship's solar array.

Abstract: Nowadays, a lot of household appliances enrich our life, their mode of operation transform from machine to remote controller. Remote control has become indispensable tool in our life, each kind of electrical appliances have its own remote controller but too much remote controllers always make inconvenience. This paper uses the idea of modularization to improve the design of infrared remote controller. With the development trend of remote controller, we obtain inspiration of mode from bamboo slips and study on how to create a new modular remote controller that can be suit for a variety of electrical appliances at the same time based on ergonomic, we propose the solution finally.

Abstract: A design method of modular joint is proposed according to the complicated structure, line exposed and heavier characteristics of multi-DOF (degree of freedom) mechanical arm. In this paper, the design of modular joint was carried on and a model of six-DOF mechanical arm was built through the research on the structure of mechanical arm. On this basis, dynamics simulation will be carried. The results show that the modular design method simplified the structure of the mechanical arm, the dynamics simulation proved it was feasible for the structure design and drive selection.

Abstract: In recent years, advanced small nuclear power reactors, namely small modular reactors (SMRs), gained widespread attention. In areas where energy can’t be provided by large scale reactors and the nuclear power plants with large scale reactors can’t compete with the non-nuclear power plant technology, SMRs, as a versatile distributed integrated energy source, which result in expanding peaceful applications of nuclear energy, have enormous potential. This article describes the characteristics and analyzes prospects and challenges of SMRs.

Abstract: Since mass customization is a kind of production and design patterns adapting to the individual needs of today's society consistent with mass production, it would inevitably lead to changes of all aspects of traditional production design and design processes. On the basis of the mass customization design and the customization position, this paper puts forward the product of classification of mass customization. It put forward a new thinking method and design process in product form design aspects.

Abstract: Based on the concept of modularity and reconfiguration, this paper adopts the function— principle—structure modeling approach, shedding light on dividing and reconstructing the modules based on the product function and finally put forward molding scheme. The author also verifies the feasibility of this kind of modeling method with the reconfigurable machine tools in turning and milling as case study.
