    From a Machine to a Collaborator
    Bozorgmehrian, Shokoufeh (Virginia Tech, 2024-01-05)
    This thesis book represents an exploration of the relationship between architecture and robotics, tailored to meet the requirements of both architecture students and professionals and any other creative user. The investigation encompasses three distinct robotic arm applications for architecture students, introduces and evaluates an innovative 3D printing application with robotic arms, and presents projects focused on the design of human-robot interaction techniques and their system development. Furthermore, the thesis showcases the development of a more intuitive human-robot interaction system and explores various user interaction methods with robotic arms for rapid prototyping and fabrication. Each experiment describes the process, level of interaction, and key takeaways. The narrative of the thesis unfolds as a journey through different applications of robotic fabrication, emphasizing the creative human as the focal point of these systems. This thesis underscores the significance of user experience research and anticipates future innovations in the evolving landscape of the creative field. The discoveries made in this exploration lay a foundation for the study and design of interfaces and interaction techniques, fostering seamless collaboration between designers and robotic systems. Keywords: Robotic Fabrication - Human-Robot Interaction (HRI) - Human-Computer Interaction (HCI) - User Experience Research - Human-Centered Design - Architecture - Art - Creative Application

    Hierarchical Structures, Computational Design, and Digital 3D Printing
    Borunda, Luis R.; Anaya, Jesús (International Association for Shell and Spatial Structures, 2022-12)
    Current advances in construction automation, especially in large-scale additive manufacturing, highlight the vast potential for robots in architecture. Robotic construction is unique in its potential to reproduce highly complex structures. To advance the question of how rapid prototyping techniques are adopted in large-scale 3D printing of forms and structures, this paper presents computational methods for the design and robotic construction of cellular membranes. This research presents a comprehensive morphological model of structurally differentiated cellular membranes based on the theoretical biology model of hierarchical structures found in natural cellular solids, and, more specifically, in trabecular bone. The morphological model originates from a system of forces in equilibrium; therefore, it presents the geometric homology of a static tensional system. This research offers a methodology for the design and manufacture of meso- to large-scale triangulated geometric configurations by discrete design methods that are suitable for the robotic fused deposition of lattices and their architectural implementation in the automated manufacturing of shell structures. First, this paper explores how a form can be digitally created by geometrically emulating a given static system of forces in space. Second, inspired by the complex mechanical behavior of cancellous bone, we apply hierarchical principles found in bone remodeling to characterize discrete units that conform to continuous trabecular-like lattices. We study the geometry, limitations, opportunities for optimization, and mechanical characteristics of the lattice. The computational design methods and additive manufacturing techniques are tested in the design and construction hierarchical structures.

    A Multi-resolution Design Methodology Based on Discrete Models
    Ladron de Guevara, Manuel; Borunda, Luis R.; Krishnamurti, Ramesh (Springer Singapore, 2019-01-01)
    The use of programming languages in design opens up unexplored and previously unworkable territories, mainly, in conventional architectural practice. In the 1990s, languages of continuity, smoothness and seamlessness dominated the architectural inquiry with the CNC milling machine as its manufacturing tool. Today’s computational design and fabrication technology look at languages of synthesis of fragments or particles, with the 3D printer as its fabrication archetype. Fundamental to this idea is the concept of resolution–the amount of information stored at any localized region. Construction of a shape is then based on multiple regions of resolution. This paper explores a novel design methodology that takes this concept of resolutions on discrete elements as a design driver for architectural practice. This research has been tested primarily through additive manufacturing techniques.

    Multi-resolution in architecture as a design driver for additive manufacturing applications
    Ladron de Guevara, Manuel; Borunda, Luis R.; Byrne, Daragh; Krishnamurti, Ramesh (SAGE, 2020-09-01)
    Additive manufacturing is evolving toward more sophisticated territory for architects and designers, mainly through the increased use of scripting tools. Recognizing this, we present a design and fabrication pipeline comprised of a class of techniques for fabrication and methods of design through discrete computational models. These support a process responsive to varied design intents: this structured workflow expands the design and fabrication space of any input shape, without having to explicitly deal with the complexity of discrete models beforehand. We discuss a multi-resolution-based methodology that incorporates discrete computational methods, spatial additive manufacturing with both robotic and commercial three-dimensional printers, as well as, a free-oriented technique. Finally, we explore the impact of computational power on design outcome, examining in-depth the concept of resolution as a design driver.
