Extracting Data for The Making

SONY DSC

The interactive exhibition set up at Chalmers Campus was inviting bypassers to build on the structures, that were constantly guided by local sensor information. The structure would balance airflow, shading and balance all at the same time, but with a hierarchical Subsumption architecture, inspired by┬áRodney Brooks’ research on autonomous robots and artificial intelligence.

Distortion 2.0

CF035698

Distortion 2.0 Investigates how the specifications of geometry and materials can create sonic effects.
The project created new interfaces between acoustical science and the build environment by integrating the usually subsequent thought areas of sound performance, design and production. The research project introduced a customized design environment, computerbased acoustic simulation, parametric modelling techniques and the steering of high end materials and digital production technology.
The project challenges the way acoustics are generally thought. Where this is often either a narrow performance solution or even afterthought the project showcases a way to think and create sound and architecture at the same time. It explores the potential of multiple sonic parameters for their sonic effects and expands the usually used single criterion, reverberation time. New digital tools and techniques were developed to virtually experiment and test design propositions; physical experiments were completed to evaluate aspects of the design that could not be calculated digitally.
The dissemniation events gave the framework in which two spaces with specifically tuned acoustic performance could be created – seperated only by 15mm of material. Here the projects sonic and aesthetic sensations could be directly experienced and the performance was validated through modeling and simulation analyses used iteratively throughout the design process and through qualitative and quantitative analysis of the full-scale installation. 2010

Lamella Flock

Lamella Flock investigates new possibilities of creating freeform structures in wood. Where this is at the moment achieved through the use of resource heavy production techniques using glue lam, complex joints, and 5-axis milling our research shows that freeform surface structures can be constructed by the use of straight beam elements. To achieve this we have utilized the principles of the traditional Zollinger lamella construction in combination with a non standardized production. Challenges arise from the complex interdependency of beam elements in the structure, and the non-linear relationship between requirements of structure, material and production. We propose an approach that utilizes principles of self-organization. This led to the development of generative digital tools that are informed by the physical 1:1 output including structural analysis, production and material knowledge. These constraints loop back into the structures geometrical setup.
Through the integration of this recursive feedback level the projects discussion is widened to the question how computational tools can help designers in the future to deal within an ever growing amount of complexity and integrate bottom-up design approaches. The project contributes to the future use of Wood as one of the few truly renewable building materials – in terms of both materiality and contemporary digital production process. Our research has shown that complex wood structures can be efficiently made and assembled using short straight beams. The key was the combination of traditional wood techniques with advanced computational methods. 2010

In this video the PID motor control is just implemented and un-calibrated. There is one for travelling up and another for travelling down on the lines. The robot travels between three xyz points in a test-loop.
