CONTEXT

MAAD thesis 2018

Weave: Fall 2017

• robotically controlled fjber deposition
• modular and reusable formwork

Robot’s Cradle: Spring 2018

• interactive fabrication process
• volumetric fjber layout

Further Explorations: Greater integration of the formwork into the fjnal design. If the formwork remains, could it have a transformative efgect on the entire structure? What happens when the formwork becomes a kinetic element that can modify the fjber arrangement over time?

CASE STUDIES

Kinetic Architecture: Interactive, responsive, transformable spaces that can encourage greater exploration and understanding of one’s surroundings. Al-Bahar Towers: 2012

• responsive facade
• used to reduce solar gain and glare

Stratus Project: 2011

• interactive interior installation
• mediating air quality and providing realtime information

CASE STUDIES

Kinetic Architecture: Heavily reliant upon secondary mechanical systems. This calls into question issues of maintenance, durability, and the long term cost of upkeep. Is there a way to reduce the number of pieces going into a project, yet still maintain the same level of interactivity? Al-Bahar Towers: 2012

• responsive facade
• used to reduce solar gain and glare

Stratus Project: 2011

• interactive interior installation
• mediating air quality and providing realtime information

CASE STUDIES

MAAD thesis 2018

Kinetic Material: The materials themselves act as sensor and actuator all in one. As the material reacts to an outside force, changes in its physical makeup cause a reaction visible at human scale. These reactions can be further leveraged by encoding logic directly into the material assembly. Reef: 2009

• interactive social environment
• shape memory alloy nitinol used as actuator

Hygroskin: 2013

• responsive pavilion
• wood veneer reacts to humidity levels

PROPOSAL

Material Actuation

An exploration into dynamic architectural spaces that do not rely upon heavily mechanized systems to achieve motion. Through the use

• f shape memory materials in combination with standard building

materials, a new architectural language of composite modules can be created that will allow emerging smart materials to be used at the scale of the built environment.

MATERIALS

MAAD thesis 2018

Shape Memory Materials

Through the Shape Memory Efgect (SME), shape memory materials (SMM) are capable of recovering their original shape after a deformation occurs. This recovery requires an outside stimulus, such as heat, light, or moisture. Shape Memory Alloys (SMA)

• metal materials that are

thermo-responsive

• most common is Nitinol

(nickel titanium) used in a ‘muscle-wire’ confjguration Shape Memory Polymers (SMP)

• plastic materials that can

respond to multiple stimuli

• lighter, cheaper, more fmexible

than SMA

• self-healing qualities

Stages of Material Exploration

Through the use of difgerent material combinations, material actuation systems (MAS) can be explored through difgerent scales. Scale of the Body

isolated experiments materials vs materials

Scale of the Room

composite systems materials vs people

Scale of the City

speculative networks materials vs environment

NEW THOUGHTS

MAAD thesis 2018

Pneumatics, Infmatables, and Robotic Architecture

After further exploration and discussion, SMAs may prove to be too limiting. Rather than employ an extensive use of an expensive, ‘smart’ material, embedding smartness into static materials through computational workfmows can allow for a greater range of design

• exploration. The worlds of soft robotics and infmatable architecture both explore ways in

which fmat, static materials can be made three dimensional, but each world operates with very difgerent goals and scales. Fluid-Driven Origami-Inspired Artifjcial Muscles: https://player.vimeo.com/video/241349581
