summary	Reviewing the current research trends in robotic fabrication around the world, the trajectory promises new opportunities for innovation in Architecture and the possible redefinition of the role of the Architect in the industry itself. New entrepreneurial, innovative start-ups are popping up everywhere challenging the traditional model of the architect. However, it also poses new questions and challenges in the education of the architect today. What are the appropriate pedagogical methods to instill enthusiasm for new technologies, materials, and craft? How do we avoid the pure application of pre-set tools, such as the use of the laser cutter has become, which in many schools around the world has caused problems rather than solving problems? How do we teach students to invent their tools especially in a society that doesn't have a strong background in the making? The primary focus of this paper is on how architectural CAAD/ CAM education through the use of robotic fabrication can enhance student's understanding, passion and knowledge of materiality, technology, and craftsmanship. The paper is based on the pedagogical set-up and method of an M. Arch I studio that was taught by the author in fall 2016 with the focus on robotic fabrication, materiality, traditional timber construction systems, tool design and digital and physical craftsmanship.

summary	This paper discusses our ongoing research into hierarchical volumetric modeling and the external forces which are motivating a shift from the traditional boundary representation (also known as BREP) that has thus far dominated design software toward a more flexible voxel-based representation capable of describing complex variable material distributions. We present Monolith; a volumetric modelling application which explores hybrid forms of digital representations and new design workflows that extend a designer's ability to describe the material properties of a 3d model at the mesoscopic and even microscopic scales. We discuss the inherent complexities in volumetric modelling and describe the design opportunities which heretofore were unavailable using existing techniques.

summary	According to the dictionary ambient architecture should be kind of object or space that relies to its surrounding or spontaneously reacts on the presence of human. Ambient architecture can also be musically expressed [1] or painted [2]. We developed special architectural building units that offer space for incorporation of intelligence and media for human interaction and for ambience.We are introducing an object called PET(ch)air made of PET(b)rick [3], a hollow transparent bottle-brick. The first intention was to generate new building unit from recycled PET material. Now that we observe its qualities, we can see it is well prepared for ambient intelligence application, especially in combination with light. For the purpose of a brick we are transforming old recycled plastic into new bottle-bricks. Using the bottle-brick as building unit we build interior objects that are ready to turn spaces into ambient rooms, places that can be customized by their visitors or spontaneously react on them. Together with this, we opened a design studio, where students were asked to develop ambient interior pieces for a special event using the method of learning by doing.

summary	The fundamentals of traditional publishing design are insufficient to support the children's book app design - book application format that brings a similar layout to printed picturebook and interactivities that resemble video games. So, how to structure your design process? And what approaches able to involve multimedia and interactivity to guide this design process? Through an exploratory, analytical and comparative research, we investigated graphic design and editorial theories, hypermedia design and game design. It was elaborated a proposal flow for digital children's book design.

summary	Traditional decorative ornaments were commonly used on the building skin of traditional architecture. Nowadays in urban areas, those ornaments become less popular for they are considered old- fashioned and due to the lack of technical function that matches with the modern building designs. Based on those issue, this paper pro- posed a type of building skin that aimed to revive a new expression of traditional decorative elements by applying digital design tools and technology as well as having an adaptive function. Traditional decora- tive ornaments merged in an adaptive skin that used traditional pat- terns as a controller of the effect of environmental changes in a build- ing could provide a new expression of the use of traditional ornaments on a building in accordance with the times. Most of the adaptive building skin used kinetic techniques in order to make its formation and pattern transformable. This paper proposed a parametric-cam mechanism to transform the pattern of traditional ornament using pre- programmed analysis data of environmental changes to parametrically drive the number of rotation phase and length of nose that generated the shape of the cams. In conclusion, this paper has developed a proto- typical tool that facilitates the new approach to kinetic decorative or- naments on building skin.

summary	This paper describes development and test of a prototype Virtual Reality system aimed at user involvement in hospital design. User needs and functional requirements are captured by interviews and observations in three case studies of ongoing projects in Denmark. Based on the identified requirements, a prototype is developed based on a multitouch display for manipulating room layout in a floor plan view and a set of Oculus Rift glasses for experiencing the design in Virtual Reality. Together with users from the studied cases, test scenarios were performed to identify possible benefits, challenges and further requirements to the system.

summary	Environmentally sound and high-performance buildings are contributing towards a sustainable future. With increased density of contemporary urban space and the urgent desire to promote building performance, a better understanding of wind behaviour will positively influence future design explorations. In the traditional sequential ar- chitectural practice, there is a gap between design and performance simulation. This paper presents an experimental and systematic study of the performance-oriented design tools, strategies and workflows utilized in the concept prototyping of a high-rise building. It describes a new approach to incorporate wind tunnel testing, computational flu- id dynamics simulation as well as parametric software, sensors and open-source electronics platform into an accessible, interactive and low-cost form generation kit, rapidly evaluating the performance of potential design options in the early design stage. As indicated in this research, environmental simulation can be a decision-making tool, in- tegrating the concept of continuity into the design process.

summary	In continuation to Generative Design Methods, this paper investigates the implementation of Biomorphic Design, supported by computational techniques in undergraduate, architectural studio education. After reviewing the main definitions of biomorphism, organicism and biomimicry synoptically, we will assess the application of a modified biomorphic method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of design outputs, student performance as well as moderators and external examiners reports initiate a constructive debate about accomplishments and failures of a design methodology which still remains alien to many undergraduate curricula.

title	Multiflight - Creating Interactive Stairs through Positive Technology
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 295-308
summary	This paper details a pedagogical project which calls for an improved design performance of the existing built environment through the use of smart technology and data-driven design. The project is an investigation into ways in which to improve the performance of a ‘pre-selected university building’ through the use of a media facade that allows for interactive experiences. Existing problems of the selected building have been identified through observation and research using a rich picture and agile approach. An underutilised staircase was selected as the focus site for a series of computational design and interactive design studies. The brief of this mini-research project aims to encourage more people to use the stairs and create a memorable experience with a technological approach through the application of a site specific interactive media installation. The project is an interactive staircase which utilises LED strips and generative sound. The project features a series of light boxes which are connected to the existing staircase balustrade. Arduino, passive infra-red sensors, and other motion detection sensors were used to allow for light and generative sound interaction with users using visual scripting tools and a generative design platform. Sensing technology was used as a real-time data-gathering device during the site analysis phase as well as an input device for the designed prototype to allow the testing of the data-driven design. This paper details the study and resultant interactive prototypes. It also discusses the exploration of performance based design ideas into design workflows and the integration of sensing tools into the design process. It concludes by identifying possible implications on using the Internet of Things concepts to facilitate the design of interactive architecture.

title	Autopoietic Features of the Urban Body's Elements - Similarity studies on network elements' attributes
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 71-78

summary	The methodology presented in this paper is grounded on the analysis and relational relocation of attributes of the urban body, deriving from the reconstruction of the urban body as a network configuration. In contrast to the hierarchical constructions, network constructions allow for multiple connections between elements, therefore being closer to the complexity of the associative forces found in the structure of the urban body.Similarity function is applied in an attempt to restructure those attributes of the urban body which emerge from the position of each element (node) in relation to other elements of the network and not from the Cartesian topology. Being able to represent material elements as nodes, counter-bodies deriving from autopoietic -network functions emerge, allowing for an inquiry in what concerns the autopoietic features of the urban body in general, focusing on the application of autopoietic functions which generate the urban body parts and components and on the multiplicity of elements' structure, in terms of association of crowds of elements and sets of attributes' values, aiming at the redefinition of proximity as similarity and of remoteness as difference.

title	Dynamic Simulation of Neighborhood Water Use - A case study of Emirati neighborhoods in Abu Dhabi, UAE
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 197-206
summary	Being located in a hot, humid and arid bioregion, as well as having a unique religious and social context, the Gulf Cooperation Council cities pose significant challenges to the achievement of sustainable urban development. Using native neighborhoods in Abu Dhabi as a case study, this ongoing research aims to develop a design methodology which utilizes both qualitative and quantitative analysis towards the holistic, feedback driven design of new neighborhood typologies for the native population. This paper focuses on the methodology and application of a water use module which measures neighborhood scale indoor and outdoor water use, an area of simulation critical to developing sustainable neighborhoods for Arab cities, yet underrepresented within the literature. The water module comprises one part of a larger toolkit that aims to measure both environmental sustainability as well as social and cultural factors unique to the context of Abu Dhabi and the gulf region.

summary	The use of mobile devices has brought important alternatives for various sectors, especially productive. Thus, studies and testing of these technologies has been used in the construction of buildings, that was not fully spread throughout the world, especially in developing countries, despite showing great potential for growth itself. Even with appropriate difficulties, the scenario for its implementation is positive, since it is certain diffusion, leaving thereby specular when these methods may be used without restriction, moreover, the use of BIM like a productivity gain factor accompanies such developments.

summary	Megalithic civilizations held tremendous knowledge surrounding the deceivingly simple task of moving heavy objects. Much of this knowledge has been lost to us from the past. This paper mines, extracts, and experiments with this knowledge to test what applications and resonance it holds with contemporary digital practice. As an experiment, a sixteen-foot tall megalith is designed, computed, and constructed to walk horizontally and stand vertically with little effort. Testing this prototype raises many questions about the relationship between form and physics. In addition, it projects practical application of such reciprocity between architectural desires and the computation of an object’s center of mass. This research contributes to ongoing efforts around the integration of physics-based solvers into the design process. It goes beyond the assumption of statics as a solution in order to ask questions about what potentials mass can contribute to the assembly and erecting of architectures to come. It engages a megalithic way of thinking which requires an intimate relationship between designer and center of mass. In doing so, it questions conventional disciplinary notions of stasis and efficiency.

summary	Constructions pertaining to built heritage represent precious material and cultural resources to be studied and preserved for present and future generations. In recent years, this built heritage is increasingly understood, documented, managed, analysed and disseminated through the application of several digital technologies; this trend has created one of the main research areas in architecture, called Digital Heritage. Digital technologies open up alternative and new possibilities in the study of tangible and intangible features of built heritage. This workshop aims to create a space to allow scholars to discuss, share and apply their knowledge in a digital heritage exercise contextualized in Oulu.

title	Geospatial Tool Evaluating Job Location Mismatch, Based on Available Workforce and Transit Options - Evaluating property location in a city using large-scale datasets
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 557-566
summary	The paper addresses the issue of spatial mismatch of jobs and the accessibility to job locations based on different age, income and industry group. Taking Atlanta as a case study, we developed a geospatial analysis tool enabling developers, the city planning bureau and the residents to identify potential sites of redevelopment with better economic development opportunities. It also aids to find potential location to live with respect to user’s choices for transit options, walkability, job location and proximity to chosen land use. We built our model on a block level in the city, imparting them a score, visualizing the data as a heat map. The metrics to compute the score included proximity to job, proximity to worker’s residence, transit availability, walkability and number of landmark elements near the site. We worked with Longitudinal Employer-Household Dynamics (LEHD) Data along with residence area characteristics (RAC) and work place area characteristic (WAC) data sets, where the total number of data-points was over 3 million. It was challenging for us to optimize computation such that the prototype performs statistical analysis and updates visualization in real time. The research further is prototyped as a web application leveraging Leaflet’s Open Street Maps API and D3 visualization plugin. The research showed that there is a high degree of spatial mismatch between home and job locations with very few jobs with driving distance within 5 -10 miles with limited transit options in Atlanta. Further, it showed that low-earning workers need to travel significantly larger distance for work compared to higher class.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary	This paper includes a brief history about the beginning of the practical application of real genetics to architecture and design. Genetics introduces a privileged point-of-view for both biology and the digital realm, and these two are the main characters (the protagonists) in our posthuman society. With all of its positive and negative aspects, the study of genetics is becoming the cornerstone of our posthuman future precisely because it is at the intersection of both fields, nature and computation, and because it is a science that can command both of them from within—one practically and the other one theoretically. Meanwhile, through genetics and biodigital architecture and design, we are searching at the frontiers of knowledge for planetary benefit. In order to enlighten us about these issues, the hero image (Figure 1) has been created within the framework of scanning electron microscope (SEM) research on the genesic level, where masses of cells organize themselves into primigenic structures. Microscope study was carried out at the same time as the aforementioned genetic research in order to find structures and to learn typologies that could be of interest for architecture, here illustrated as an alternative landscape of the future. Behind this hero image is the laboratory’s first effort to begin the real application of genetics to architecture, thereby fighti hti ng for the sustainability of our entire planet and a better world

summary	Generative Design (GD) is a valuable asset for architecture because it provides opportunities for innovation and improvement in the design process. Despite its availability for Computer-Aided De- sign (CAD), there are few applications of GD within the Building In- formation Modelling (BIM) paradigm, and those that exist suffer from portability issues. A portable program is one that will not only work in the application it was originally written for, but also in others with equivalent results. This paper proposes a solution that explores porta- ble GD in the context of BIM. We also propose a set of guidelines for a programming methodology for GD, adapted to the BIM paradigm. In the end, we evaluate our solution using a practical example.
