I will discuss 2 different programs in this post: a 2D finite element analysis program and a Robot arm. In my next post I will discuss my progress for my thesis.
I will not go too in-depth, so if there are any questions feel free to comment.

Here is a quick picture of Dawn. I found the .stl file online and wrote a quick parser to make my program able to plot it.
2D FEA:
Without getting to deep into it, I made an FEA program for my Intro to Finite Element's class (my partner is doing the 3D analysis in Abaqus). The object being analyzed is the Philae Lander's leg. We are doing static analyses for the stress, strain, internal forces, and deformation for a resting Philae as well as when it was compacted before the first bounce. Assuming no energy dissipation (pretty bad assumption since there was lots of kinetic dissipation), the maximum internal energy is proportional to the square of the velocity after the bounce, which is estimated to be around 38 cm/s.
Here is what it looks like:
Robotics:
While we have not yet completed the project, my main contribution so far has been this robot which is able to get out of a randomly generated enclosure. It does this by always turning right, after the first left. It saves where it has been as an artificial "memory" (very basic AI), and if it "sees" the same spot over and over it randomizes it's movements until a new wall has been found.
I created the simulated robot since we were having trouble interfacting with the real robot (PhantomOmni).
Oh yeah, on that note I figured out how to take complex videos on matlab, the buffer needs to be set as "zbuffer" otherwise it does not do something that it has to do.
Anyways, here is a video. For best results try to play both videos at the same time:
