A team called Osteobotics from AADRL is proposing a flexible automated robotic arm fabrication system, which exploits phase changing material and utilises robotic arms intelligence by executing accurate repetitive actions. The system, enclosed in a mobile cell, allows the fabrication of a continuous lattice structure that can be melted and reused again or just be left to biodegrade. The dynamism and reusability of the system result in variant temporary architectural applications, where the manufactured lattice is manually assembled on site using heat only.
The studio focuses on the production of architecture via an understanding of the critical physical processes of formation and adaptation in nature, their control and execution by highly efficient code that results in finding form and life-cycle adaptations through a computer-aided, interactive search of large solution spaces. We are in the era of speed, and with more demands on the line, the urge of temporary disposable products have never been higher. Currently, 1,418 pops ups exist in London and the numbers keep rising by the day, and so are waste and cost. Architecture and construction contribute to seventy percent of the overall waste production in London. Seventy percent of this waste ends up in landfills. By the year 2020, London’s municipality is aiming to reduce landfill usage to twenty percent and to increase recycling by fourteen percent.
This demands a system that rethinks the problem with a holistic approach from material to fabrication. Thus, Osteobotics is proposing a flexible automated robotic arm fabrication system that is based on programming a reusable and biodegradable material with the parameters of robotic automation. The purpose behind this research was to design a fabrication system that is able to produce a reusable, biodegradable, and temporary architecture. Therefore, it was focused on designing a flexible system that is characterised by being joint-less, mono-material, and self-supported as well as form-work less. The fabrication system is enclosed in a mobile cell, which shifts the paradigm of the factory versus prefabricated component methodology to phase changing material versus industrial robotic arms intelligence. In addition, the benefits of having an on-site industrial fabrication system with minimum manual assembly greatly decrease the execution times and the use of scaffolding. As a result, the overall flexibility of the proposed system enables the opportunity of creating variant architecture applications.
Taking into consideration the accuracy and constraints of industrial robotic arms within the physical and digital material studies, structural beams were computed to be extruded in between mono-material nodes by simple repetitive actions. The customisation of the industrial robotic arm by the end-effector was crucial to generate an interface between its accuracy and the material malleability end-effectors were created, one for pulling the tetrahedron nodes and the other for pulling plates. Although freezing was manual at this stage, it was integrated to both end-effectors at a later stage of the project.
