@misc{14042, abstract = {{This paper investigates co-creativity in architectural robotics through a design-research experiment that repositions the robot from a fabrication tool to an active collaborator in spatial exploration. A turn-based assembly process enables a human designer and a robotic arm to alternately place modular bricks within a shared three-dimensional environment. Each move is evaluated through computational rules—support, stability, and collision—and interpreted in real time via an AI image-to-image diffusion model. This sequential exchange establishes a reciprocal design dialogue: the human reads the robot’s action as a spatial proposition, while the robot responds to the evolving structure. Creative agency becomes distributed across human and machine, encouraging reflection on intent and positioning robotic intelligence as a source of suggestion rather than execution. By prioritizing responsiveness and interpretation over efficiency, the research challenges conventional file-to-factory paradigms and frames robotics as an active participant in design thinking. It contributes to discussions on human–machine collaboration by proposing co-creative robotics as a framework for rethinking authorship in architecture. Keywords.

By processing point cloud data from the camera and aligning it with real-world coordinates, the system achieves precise object localization, enabling tasks such as element handling and assembly.

It focuses on researching the application of artificial intelligence (AI) in architectural design, modelling, production and management processes, particularly on the communication between users, processes and the building itself in various development and life-time phases. Hence the research aims to develop new tools and AI-supported process chains for the design, production and communication of architecture. This includes the training and implementing prototypical machine learning algorithms to autonomously evolve and optimize field-specific processes and workflows. As mentioned above, a critical question KI.BAU explores is how we, as planners, builders and users, will communicate with architecture in the future, in its phases of creation and use but also beyond. This also involves, besides virtual interfaces, examining the physical interaction with a building, its behaviour, responsiveness and adaptation to certain conditions. The primary goal of the research at KI.BAU is to transform architecture into an intelligent, to some degree self-sustaining, self-reflective and maybe even evolving ‘ecological system’. This system should be comprehensively linked with its creators, users, devices, computers, its (biological) environment and networks. Consequently, a building must be viewed as an organism that communicates, interacts and adapts to other connected or related organisms and entities. }}, author = {{Sachs, Hans}}, booktitle = {{Synthetic realities: New Frontiers in AI-driven Design, Fabrication and Materiality}}, editor = {{Kretzer, Manuel}}, isbn = {{978-3887781088}}, keywords = {{AI, Artificial Intelligence, Architecture, Build Environment, Building Construction, Ecology of Architecture}}, pages = {{14}}, publisher = {{AADR – Art Architecture Design Research}}, title = {{{KI.BAU Artificial Intelligence in Architecture}}}, year = {{2024}}, } @misc{13172, abstract = {{Pilze als konstruktives Baumaterial für eine nachhaltige Zukunft?
