Senior Telemaster Autonomous Take Off

Posted on October 3, 2012 at 1:26pm 2 Comments

http://www.youtube.com/watch?v=fejOaW2k7Mc

This is probably basic/simple stuff, but here's a quick (raw) video of a fully autonomous wheeled take off in a Senior Telemaster.  The basic strategy used so far is to steer with the rudder to hold heading error to zero.  Then when airborne, use a small amount…

UAS Search and Rescue Demo (Simulation)

Posted on September 25, 2011 at 9:59am 9 Comments

Simulators can be powerful tools for developing and testing UAS flight control systems as well as prototyping new ideas.  Here is an interactive FlightGear based demonstration showing:

  • Auto-launch from a carrier.
  • Circle holds.
  • Route following.
  • Gyro stabilized…

Add an inexpensive oscilloscope to your DIY tool box.

Posted on August 5, 2011 at 9:21am 4 Comments



Recently I purchased an inexpensive usb based oscilloscope to help me do some low level electronics debugging.  Owning an oscilloscope is so cool I just had to tell everyone about it!  And the price of these USB-based oscilloscopes are in range of many hobbiests.  Now I'm kicking myself for…

Tracking Ocean Debris in the North Pacific

Posted on April 14, 2011 at 2:00pm 4 Comments



This is a movie showing the drift pattern of some ocean debris (a large houser line.) We were out 1000nm north of Hawaii on a NOAA research ship. This cruise was part of a project that has also provided a small amount of funding to develop a "marinized" small UAV that could be deployed from a variety of ship sizes with minimal infrastructure requirements.

We found… Continue

Shadow Cam

Posted on October 16, 2010 at 5:49am 5 Comments



Shadow Cam.



This is a little proof of concept video I just put together. The goal is to always keep my aircraft's shadow in the field of view.



Equipment: Senior Telemaster. Fly-Cam-One-3 with built in pan/tilt. Sparkfun 6DOFv4 IMU (it was laying around so I used it.) Gumstix flight computer. Ardupilot used for controlling pan/tilt servos on the camera.



The flight is 100% manually piloted. Camera is 100% automatically… Continue

thank you curt ... this was the first useful feedback that i received so i decided i must be in the wrong discussion group and closed it.

i'll work my side and see what we might be able to do. ...
note: we will seek out a few to test the prototypes once we are ready.

regards,
robert

Thats awesome. I will find time to sit down with you if your coming out here. I would love to learn more about some of this stuff. Let me know when your going to be here.

do you teach at the u of m?
At 9:42pm on December 6, 2008, corey said…
oh okay, i thought i saw something about the u on your website and i guess i misinterpreted it.

thats interesting though, are you involved with the uav research group there? i'm going to be transferring to a university next fall and am curious how the u of m's aerospace engineering program compares with other public universities. have any thoughts on that one?

yeah that would be great, the malolo looks impressive especially with water landing capability!

Hi Curt,

I'd love to see your set up. When you're ready, just give me a shout. My home number is (952)445-0498.

Thanks,
Paul

how did the ocean demos go?
At 10:31pm on January 22, 2009, corey said…
its too bad about the receiver. i work for tsa and can tell you that it's not likely that someone deliberately took it, but there may be a chance they had to search your property and they mistakenly didn't replace it. was there an inspection notice anywhere inside when you got to hawaii? generally luggage rolls through xray machines without any human interaction, unless it detects something suspect, at which point a person would put their hands on it.

i can provide you with the number to call where they maintain lost property. the guy has been there forever and logs everything that comes and goes, so if they have it he'd know. you wouldn't believe all weird crap they have have down there. but they do only retain it for a period of time before it's given to charity, so let me know soon if you want the number!

i guess on the lighter side, you got 1 successful flight and maybe even a tan!

Hi Curt,
due to your familiarity with FlightGear I figured to ask you: what is GPS resolution as reported by FlightGear? I think that for x-plane sim it's about 165 meters ( 0.1 miles) for longitude and 107m ( 0.07 miles) for lat - can FlightGear's GPS provide GPS data with better resolution?
Thanks
At 1:53am on December 23, 2009, automatik said…
Hi Curt,
I had an 'oops' moment with my earlier comment to you - x-planes GPS resolution is much better then what I mentioned - I had a bug in the code where I am decoding the data....I would still be interested in FlightGear's GPS data resolution..
