Cyber-Physical Fabrication Platform: Fluid Fabrication

Research Project 4-2 (RP 4-2)

CYBER‐PHYSICAL FABRICATION PLATFORM: FLUID FABRICATION – EXTENDING THE ADAPTIVITY OF ISLAND-BASED FABRICATION AND THE DESIGN-TO-FABRICATION RECIPROCITY THROUGH MULTI-UNIT COLLABORATION

This project aims to extend the semi-autonomous cyber-physical prefabrication platform developed in the first phase (RP 4-1) with respect to three key aspects: workpiece logistics, human-machine collaboration and, ultimately, higher-level cyber-physical fabrication and construction integration. The aim is to extend the platform's fabrication-design space for co-design and to increase its flexibility and capacity.

The previous project focused on the development of flexible robotic fabrication modules, incorporating augmented reality supported human craftsmanship, and their evaluation in a practical use case. This setup will now be extended to connect multiple fabrication modules and potentially other systems through flexible transport modules in the form of an autonomous mobile robot (AMR) that connects the fabrication modules. This integrated workpiece handling is an important constituent for a project-based fabrication design space extension for the prefabrication of multi-storey timber-building systems. It can be configured to work autonomously, in pre-existing fabrication setups, both off-site and on-site, and will connect various fabrication modules developed in the Research Projects in RP 4-1, RP 8-1, RP 16-1 and RP 26-1, among others.

This project also aims to intensify human-robot collaboration in the prefabrication from one robotic system and one human to multi-unit collaboration. The new challenge will be to lower the entry level for fabrication control of human craft using augmented reality (AR) technology in such more complex setups. To this end, research into the use of multimodal interaction will extend human skill sets. Different models of these autonomous and collaborative skills will extend the capabilities of the cyber-physical prefabrication platform developed in the previous project. Multi-level feedback throughout the design and fabrication solution space aims to establish a continuous feedback loop from the initial design phase to online adaptation of the fabrication process. The new developments will be tested with the prefabrication of the building system developed in RP 3-1 and RP 3-2. In this way, this project also aims to lay the foundations for a fully integrated cyber-physical prefabrication and construction process.
