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 week I created movement functionality from scratch, although was not able to test this fully. I had also used Unreal's grabbable object meshes to help test the controller (although this was not fully tested either). What I was able to test was the object physics of the grabbable object with...

This past week, I focused on designing more modular components to add to Roco as well as programming motors using the Arduino microcontroller to familiarize and simulate different types of motion. I was able to understand Roco much better through the process of designing these new components; specif...

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...

The current project that is being worked on is building off of the RoboGrammar, a graph heuristic search. Rather than a user needing to input a prebuilt terrain, a user may be able to use simple interactions to design an environment such as the width and length of a hill. This week my overall goal...

These past weeks, I've been experimenting with Interactive Robogami which is an end-to-end design system for ground locomotion robots. It greatly simplifies the design for cut and fold robots, has a library of modular components to choose from, and has many performance and fabrication metrics includ...

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...

Last week (06/20/2022 - 06/27/2022) I went through the RoCo code and library to familiarize with existing structure configurations. I wanted to experience the claimed ease and speed of building robots/robot structures RoCo for myself. Setting up RoCo was took much longer than anticipated as certai...

Boards sent out a while ago have finally come back, and they are working! Above is the charlieplexed LED matrix board with a basic firmware load that draws a smiley face on the LED matrix. It also allows the user to select a different image (just a frowning face for now, but it needs a duck) t...

One again, using custom test equipment (the DC supplies at the top and bottom) ... to bring up custom test equipment (the BLE multimeter at the center)! This time around, there's no blue wires, and things generally went according to plan. The one place where things didn't go according to plan (an...
