Sphere Packing Honors Thesis Proposal

Dear Reader, I’ve decided to do a senior capstone project involving the material I’ve presented in the previous posts. Therefore, in the previous two weeks I’ve been working on writing up my honors thesis proposal for sphere packing. My proposal can be found at the following link if you wish to see it: Xiang Chen’s […]

FreeCAD FEM Module Results

Dear Reader, In accordance with my timeline, I have explored the capabilities of FreeCAD’s FEM Module along with other auxiliary modules in order to find a reliable software program that enables easy application and analysis of stress on a 3D object. I explored the basic functionality on a trivial yet essential structure as shown in […]

Success with ROS and OpenNI, Python Scripting with OpenCV

This week I have finally found success with our implementation of ROS and OpenNI on our Linux Mint machine in the Forensics Lab. I ended up resolving our global frame issue and have received images from the Asus Xtion Pro Live in addition to point clouds!

Project Timeline for Structural Refinement to Counter Application of Forces

Dear Reader, The sphere packing software currently generates 3D internal structural meshes for hollow 3D objects. However, our current usage of sphere packing does not provide a major improvement over simple manual generation of uniform truss structures. The true advantage to using sphere packing is actually the ability to selectively manipulate local regions of the […]

The Perko Praxinoscope and the Shrikhande Graph

As I mentioned in my previous update, I fixed the design for the Perko knots on the pegs, and made a decision on designing the Shrikhande graph so that it looked like the Rook’s graph. Well I sent them off to Shapeways and was overjoyed when I received them a week or so later: they were […]

ROS and OpenNI Update

This past week I have worked on installation ROS (Robot Operating System) on our desktop in the Ars Geometrica Lab in ISAT. With the ROS installation complete and usable, I began focusing on getting the OpenNI_launch and OpenNI_camera nodes working together to produce visuals from the Asus Xtion Pro Live.

Resulting Prints of the STL Infills

Dear Reader, This week we’re able to see some physical prints of the stl infills generated through the process described my last week’s post. The prints and pictures are all courtesy of Professor John Bowers. Here are photos of a print using the shell included: Thanks for tuning in this week. -Xiang
