From Shandor's email on the matter:

Hey ARL,

It has come to my attention that many here are unfamiliar with the ARL JabRef. It is a magical tool. JabRef is profound wizardry that enables mere graduate students to manage scores of references with ease, or which the Aerospace Robotics Lab is a humble user.

Yea, follow the directions below, and thou shalt exalt it's powers. This is likely to go on the ARL blog as well.

Just wanted to put out some instructions for the adding of papers to the website, so that the new folks can do it, and the older folks don't forget. :)
We are each responsible for uploading our own publications, as it is much easier for the person with the original pdf, and sometimes the conferences take forever (if ever at all) to post the documents online.

I've received a couple new Robovero boards to try out (thanks Gordon). These ones are R3902, unfortunately they still have the same problem with L3 getting in the way of a capacitor on the newer Overo boards but that's supposed to be fixed in R4000. However, they made a couple of changes to the circuitry. One change was the addition of power control over the IMU using one of the Robovero's GPIO pins. Kind of makes sense, lets you power up/down the IMU at will, nice change, easily implemented. The other change was adding a reset circuit to the Overo's GPIO70 pin.

Now that I'm using my new Robovero/Mikrokopter interface board, I figured it was about time that I recalibrated the accelerometer and compass to reflect the new orientation.  When I started the recalibration procedure I realized that I never really documented my calibration in the first place.  Here's how I did it this time:Accelerometer (roll/pitch)

Well after rebuilding my controller build for the Mikrokopter with the new PCB I designed I found out yesterday there was a problem.

Here's a list of some of the things you need to install to get the AUV code working with your 12.04 install

0) Update

sudo apt-get update

1) Install Subversion

sudo apt-get install subversion

2) Install g++, other build software

sudo apt-get build-essential

3) Install PCL

sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-all

4) Download newmat (google it, get the tarball, extract, then copy)

sudo cp -r newmat /usr/local/
cd /usr/local/newmat
sudo make -f nm_gnu.mak

5) Get more stuff

Now that I've got my attittude EKF running on the Robovero, it's time to get some position estimates as well. To do that I need to have position measurements. While indoors I'll be using our NaturalPoint OptiTrack system as a pseudo GPS measurement. I already had the Simulink block ready to go so adding that in shouldn't have been a problem. However, when I tried to run the code I was never able to receive any information from the OptiTrack system even though my Windows machine could no problem.

After putting it off for a while I finally got around to calibrating the compass on the Robovero. Basically what this does is measure the effects of hard iron (metal objects around the compass), soft iron (circuit effects) and misalignment between the chip axis and the Robovero body axis. To my surprise the compass wasn't too bad, basically wanding around the compass should give a unit sphere centered at 0. It was close but after applying the calibration procedure given in LSM303DLH-compass-app-note.pdf, I came out with the following compass measurements.
