This week I was able to make a square cell using wood and foam. On my previous blog posts I had been working with acrylic paper, which has some relative movement vertically and horizontally. My goal was to limit the degrees of freedom of the auxetic structure to be only horizontal at the hinges. I'm...

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...

This week I focused on fine tuning my RoCo component designs to fit with the electronics and assemble my first fully functional cut and fold robot. I wanted to make sure that my method for production would be feasible before I continued designing more components for robots with more functionalities....

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...

My last few blog posts have been about bringing up example boards designed in our HDL, especially ones incorporating the new features of port arrays and multipack devices. Some of them were more toy examples and intended as proofs-of-concepts (like the LED matrix), while others were more practical...

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 spent a lot of time familiarizing myself with making cutouts in RoCo which was quite difficult compared to creating the components by connecting faces, edges, and tabs. Creating cutouts and knowing how to position them in RoCo is particularly important and relevant to my project because...

This week I worked on debugging some of the movement issues from the previous week. I also worked on the grabbing aspects of objects as I wanted to remove the physics of objects and allow these objects to interact with each other. I demonstrated the object's grabbable aspect by placing an object tha...

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...
