Precise Imprecision flexible construction with robotic fabric formwork / / / /

Digital Fabrication. Material Research Ann Arbor, Michigan 180*80*40 in Yi-Liang Ko, Hong-Fen Lo

Precise Imprecision defines a new robotic construction technique through stack casting fabric molds by KUKA industrial robot and human, and re-defines “precise” and “imprecise” in digital fabrication. Physically, fabric form-fit property allows us to get customized shapes from surrounding precast units, but the process is extremely unpredictable. Computationally, robotic assembly creates more controllable design parameters and reduces many frameworks or labors. Based on these two features, stack casting integrates cast and construction processes simultaneously to improve fabrication efficiency. The unique soft shape and tight form-fit edge connections reflect the dry fitted masonry techniques in traditional Inca Wall. Therefore, through the precise form-fit system and imprecise material variations, Precise Imprecision combines physical performance and digital configuration to build a curvature Inca Wall. Precise robotic assembly causes imprecise placement, imprecise fabric deformation creates precise connection, or vice versa. This fun fact changes the stereotype that precise mold system and digital fabrication are inseparable.

Through the collaboration with sewing machine, Zund, 3-axis CNC router and industrial robots, 116 unique units are produced, cast, and assembled in a high-efficient workflow. The workflow includes sharpening the manufacturing of molds and customizing the end effector which works for casting and assembly. Due to the limitation of working space, designers separate the curvature wall into two pieces and explore different collaborations between robots.

Interpreting Nature by Digital Tectonics a pavilion construction / Digital Fabrication. Material Research / Wulaokeng, Yilan, Taiwan / 860*620*250 cm This research combines CAD and CAM to investigate the process of digital fabrication. Inspired by the natural forming rule, the pavilion structure comes from the growth rule of Fibonacci numbers which is similar to the arrangement of sunower seeds. Computationally, I create an oval donut and overlay it by points. Then connect the dots into lines. The pattern of the interwoven formation becomes the structural system. Physically, according to the same structural behavior, I design a pavilion which could be able to accommodate people in it. This project acts thin shell structure system. To reduce self-weight, I utilize plywood and colored PETG sheets on this pavilion. Additionally, the shadow of the pavilion also reects the Fibonacci pattern.

Augmented Reality doesn’t only describe a method where the environment is perceivable and is overlaid with 3D information, but also allows to demonstrate complex information on site. With advanced technology, architects can convey digital information to a construction crew. In this project, we utilized an application, Fologram, and an AR device, Hololens, to build this pavilion. There are three steps to build a pavilion through AR method. Through modeling in computer, we could get all information such as lengths, curvatures, and patterns of this pavilion first. Then testing the material, PEX pipe, by Hololens to check if these pipes could achieve the pattern or not. Finally, locating 3D positions on site and erecting the flat pattern made by pipes. Through AR device, the physical model could be adjusted in real-time. This project demonstrates a practice of AR building process.

the Poetry about Tamsui a church designed by tide / Architectural Design / Tamsui, New Taipei City, Taiwan / 1,534 m2


The Poetry about Tamsui is an architecture project. It inspired by an observation of the natural phenomenon, tides. Tamsui sits at the confluence of Taiwan Strait and the Tamsui River. It named after the river, which means fresh water. It's known for the magnificent sunset and the horizontal estuary landscape. In this case, I designed a church and a community center at this site, the Tamsui First Fishing Harbor. It's a small fishing harbor just providing some traditional fishing boats to anchor. Tamsui is located at the estuary of the Tamsui River, so the tides are extremely important here. As in Venice, both ebb and flow could shape different landscapes for Tamsui. Meanwhile, it also affects the activities of residents. Through connecting the site with the river, tides can also float within the site freely. Through the comprehension of tidal information, both the annual mean of high and the low tide level could be a basis for designing. The flow will submerge the church. And it'll reveal again on the ebb. It turns out the architecture strengthens the environmental characteristics and becomes an integral part of the environment.

This is a reconstruction project of urban open space. From the urban aspect, the site is located at the nod of a linear green open system. The project is based on the existing square, transforming what was once an inhospitable open space into a new communal city garden and an open ďŹ eld with a stage for various activities. Through thinning the extra plants, the street corner square provides a better environment for remaining trees. The fountain square is formed by a series of ledges with cascading water and jets arching toward the center to mask traďŹƒc noise and temper the summer climate. My task in this project is the main designer, digital modeling, and construction drawing. The project has accomplished in 2016.

NTPU Residences a student dormitory design / / / /

Architecture Design Sanxia, New Taipei City, Taiwan 2,409 m2 fa+p This is a student dormitory design project.

Because the location of building faces the east and the west, a timber facade screen system and a deep balcony are designed to provide certain privacy and help keep the building cool in the sun. We create a standard plan for accommodation, then insert dierent size and function common spaces in the building. And trying to increase the natural wind circulation inside, to produce a comfortable living environment. In this project, I utilize Rhino’s plug-in, Grasshopper, to create the whole random timber screen pattern. Additionally, we also use Revit to build the interiors for collaborating with the contractor easily. My task in this project is the main designer, digital modeling, physical modeling, drawing, and producing the proposal. The project wins the 2nd place in proposal competition.

This project is a complex including a fire station, training facility, dormitory, and classrooms. As a fire department, creating an efficient circulation is our priority. The station uses volumes as an architectural element. Each individual box defines a different function of this fire station. Through the main pathway which connects the big roof garage and dormitory, we create a highly efficient circulation for the fire team. The rest of boxes provide the fire team a better environment to learn and simulate emergency situations while bringing natural light and fresh air into the building. Additionally, we also use Revit to build the interiors for collaborating with the contractor easily. My task in this project is the main designer, digital modeling, physical modeling, drawing, and producing the proposal. The project wins the 2nd place in proposal competition.

Architecture Design Sanxia, New Taipei City, Taiwan 12,850 m2 fa+p


This is a commons design project. The site is next to the landmark, Heart Lake, in the campus. Inspired by the horizontal landscape, we create a oating deck to accommodate a dining hall, kitchens, and its facilities on the ground oor. This wide roof plays a major role in this project. It not only provides an open stage as a good spot to enjoy the wonderful lake view but also a place to locate the featured stores on the second oor. In the night, the light from stores also illuminates the lake as a series of glowing boulders by the shore. My task in this project is the main designer, digital modeling, drawing, and producing the proposal. The project is under construction from 2018.

Walking in the Blur an interactive installation for social space / / / /

Walking in the Blur is an interactive installation project. The idea lies in receiving information precisely and responding to it immediately. It aims to develop a temporary field with an array of interactive and dynamic objects. When the heavy fog rises, it’s hard to see the usual path, but the light will penetrate through. Invisibility makes us feel differently. When fog covers the playground of Tamkang, it's no longer ordinary. Therefore, we want to create a fog-forest of light which can interact with people. The goal of this project is providing a completely different spatial experience from usual. The object consists of numerous devices. With coding, the mechanical system could drive the installation move and respond to human reactions. Through the bottom sensors, it'll respond to human activities by moving toward them. The swarm of devices will form an atmosphere and transform the original spatial experience.

Robotic Fabrication wood-brick column and styrofoam wall formation / Digital Fabrication. Material Research / 30*30*80 cm, 120*40*160 cm / Yi-Liang Ko, Hsin-Ying Huang

Robotic Fabrication is a practical project that aims to comprehend the operation principles, basic settings, limitations of material and robotic fabrication. To understand how to apply two basic type applications of robotic fabrication which are orientation and end-effector. We employ wood-bricks (60*32*16 mm) and Styrofoam cubes (200*200*200 mm and 400*200*200 mm) to create a column and a wall respectively. In the woodbrick column project, solving the order of orientation route is the priority. With parametric modeling, the brick column will be simulated in visual environment and then generate g-code to upload to the robotic arm. Finally, through the collaboration between the custom-made gripper and arm to build the column. In the Styrofoam wall project, the purpose is designing a Styrofoam unit. Through a simple concept of rotation, we define a route of robotic arm to cooperate with the fixed hot-wire bow cutter. Although there is one type of unit, a variety of combination enriches the expression of the wall as well.

Metal Interlace _0 weld assembly

/ 2018 / Digital Fabrication / Abstract

Metal Interlace 0 weld assembly / Digital Fabrication / 52*12*24 in / Yi-Liang Ko, Maryam Alhajri, Joon Kang

The robotic rod bending process developed at the Taubman College allows a generic industrial robot to cut and bend steel rods into specific length shapes. Based on the tools above, Metal Interlace aims to develop an aggregation system without welding. Through exploring different lengths, curvatures, and angles, we created 3 types of 2D units and a specific assembly order to form 3D geometry. The main idea is utilizing hook systems to connect different units together by a series of actions such as sliding, rotating, and folding. The limitation of rod bender’s folding angle and 7-Axis Robot’s grip length constrain the geometry of each rod. Therefore, this is an experiment played between digital modeling and physical restriction back and forth. For the final piece, we created an assembly system for a foldable and continuous metal fence.

Spatial Printing mesh mold casting / Digital Fabrication. Material Research / 36*06*20 cm, 24*10*12 cm / Yi-Liang Ko, Hong-Fen Lo

Spatial Printing aims to investigate parameters of the extrusion process through KUKA 7-Axis Robot. This extremely delicate process is involved in many factors. Besides comprehend the basis of operating robots, designers should be aware of material properties and the deviation between computational design and physical fabrication. There are three main areas would affect the result. The first one is geometry design. The final shape is a compromise between the tool end size and the carbon fiber properties. Another is toolpath. To keep the extrusion process smoothly, a continuous toolpath is generated through reorganizing points data and assign overlapping range. In addition to the factors mentioned above, the final one is end-effector. How to adjust velocity and temperature is quite a challenge. All parameters should correspond to geometry and toolpath. Through control cooling system and the speed, spatial printing could be produced.

3D Tiling polystyrene vacuum forming / Digital Fabrication. Material Research / 12*12*03 in / Yi-Liang Ko, Shan-Chun Wen

3D Tiling aims to develop a 3D tile or series of tiles that aggregate to create a complete 3D surface. How to create a complicated surface through an efficient way is the goal of this project. To achieve multiple patterns and maximize efficiency, we created an identical unit which could be arranged in four different directions. Through combining CNC Router and vacuum machine, we contrived a workflow of production unit molds. Because the unit is identical, we only need one CNC-milled positive MDF unit. With vacuum machine, we could get vacuum-formed molds as many as we can. Through arranging in a different orientation, we could achieve 16 different continuous patterns between two units. Additionally, a light-weight unit could be achieved by integrating Glass Fiber Reinforced Concrete (GFRC). Therefore, this module system provides not only an efficient production process but also a practical assembly methodology.
