The 8-week summer program has ended, but that does not mean that this project ended. For whoever decides to pick up this project in the future I would like to leave some tips to help you get started. The Github contains various folders: DXF_Files Contains a collection of .dxf files which a...

This past week I have been working on physically creating auxetic cell array dicussed in my past blog post. To manufacture these cell arrangments I decided to use the following materials: cardstock, Polyethylene terephthalate (PET), and Polyeurethane rubber. (Images present the materials in that o...

With the goal of designing and creating my own elastic geodesic grids, I prepared some 3D surfaces in Rhino that I wish to approximate with a grid structure. I first started with making a dome shape. It is simple and basic, but helped teach me how to make some other designs. For example, I d...

Using the interactice roco compiler I was able to design a canoe of the following dimensions: boat.depth: 20.00 mm boat.length: 100.00 mm boat.width: 50.00 mm bow.point: 50.00 mm seats: 1 stern.point: 50.00 The goal of this was to design a boat which could then be possibly used with the grassho...

Unit cells were presented last week in the form of a table. As previoulsly described, auxetic cells can be repeated and connected to one another to form repeating patterns which can then be actuated to form different kinds of curved surfaces. The goal of this week was to make use of the unit cells a...

This week, I worked on the fabrication of an elastic geodesic grid. I started with these plans in a PDF format. Then I had to convert the PDF file into a readable DXF file to open it in Inkscape. I resized the the plans to fit a 12" x 24" space and adjusted each pin hole/slot to be able to fi...

This week I have been reading up on literature regarding auxetic unit cells. This week I decided to rechange my focus to looking at different unit cells because after last week when I made the auxetic structure I realized that the auxetic cells do not behave the way that is shown in a simulation. I...

This past week I used Rhino 7 to create .dxf files that can be used with the laser cutter and paper cutter (the CAMEOS). Designs were made within in the Rhino software and were manufactured using Vinyl Polyester as the material. (The plastic roll of material in the lab). Before making a structure...

This past week I looked for various existing repositories/resources that were are discussed in reasearch papers regarding the design of auxetic structures. I took a particular emphasis on using the resources discussed in the paper Bistable Auxetic Surface Structures. The design of auxetics disc...

There are two variations to the designs of the motor handles, one for the vertical motor and the other for horizontal motors. They are designed with the intention of keeping the weight low and sturdy as this is used with a brushless motor. Horizontal Motors: The design has a hole going strai...
