About Me:
I am a propulsion research and development engineer for NASA-Marshall Space Flight Center. I work on a wide range of propulsion systems from large solid and liquid rocket motors to in space plasma thrusters. My primary strengths are software development, simulation, and test. I am also involved with design and analysis of various systems.
Please tell us a bit about your UAV interest
I am interested in all things UAV related. I have a pretty standard educational background that leans towards software development, turbomachinery, control theory, and supersonic flow.

"Did you make any progress with this? I am trying to do something very similar and when I bring up any tool for monitoring the serial port, it reads about 1000 bytes of data until everything freezes up. It is quite strange."
"And yet another video of NASA MSFC's Mighty Eagle filmed with our 3DR quad.

"Here are some additional pictures from the competition:

"The flight computer and ground software are sold separately btw."
"Like Chris said, the flight computer and the ground station software are around $14.5K. In addition to that, they had some other electronics for video and such. To their credit, they designed and built the plane from scratch which was pretty cool."
"The Kennedy folks a sweet launcher:

"And by repurpose, I mean that I would like to write my own code in the Arduino IDE yet still have access to the IMU."
It seems as though there have been a few people asking about how they can access the raw sensor information being generated by the IMU's on the Ardupilot boards. Is there a good reason as to why that hasn't been addressed or am I just missing…
"Garrick and I are both civil servants with NASA. He works in the avionics group and I work in our propulsion group. We were given a little bit of play money to go work on UAV's and we do this stuff on the side. We have other people involved from…"
"Not to mention we had over 600 people watching. Pucker factor was definitely a 10/10."
We have been running into an issue quite often when flying at certain altitudes and 'near' structures. We are doing autonomous waypoint navigation and all of a sudden the GPS position jumps anywhere from several feet up to a few hundred feet.…
"I completely agree; however, I am a huge fan of 3D printing and making things open source. I work for NASA in a propulsion research lab and if there is any effort to make propulsion more accessible regardless of the scale, I am all for it."
"Now this is what I'm talking about. I know one of their 'Team' members, Tim Pickens. He really is an interesting person. He and a few others built a rocket propelled truck using roofing tar and nitrous oxide (I think) with a Xbox 360 controller."
I am sure that some of you have experienced the same issue that we have. We are flying a rather heavy hexacopter configuration which pulls a substantial amount of current just to hover. Due to the proximity of the power distribution board and the…
We attempted a little parametric study to optimize our UAV's flight time using the motors, propellers, and # of batteries as our controllable variables. First we optimized the rotor/motor combinations which is described in another thread. Then we…
