FunCub

Hi all,

 

just in case someone should be interested using a FunCub I posted a couple of videos showing some flight excerpts.


 

FunCub flight excerpts from Riccardo Kuebler on Vimeo.

Glider towing with a FunCub from Riccardo Kuebler on Vimeo.


 

In the first I do some aerobatics.

In the second we do an Easyglider tow.

 

Plane is still not equipped with any autopilot, but this could help if someone is wondering about it. There is plenty of room available for everything.

 

Motor is Turnigy TR 35-42D 1000kv with APC 12x6

I use a Turnigy 60A ESC. It's quiet exaggerated. I will swap with a 50A that's more than enough.

Servos are for elevator and rudder Hitec HS81, ailerons and flaps MKS DS460, tow a Turnigy DS480 (only because I had it laying around).

Current is 35A with 3300-3s lipo.

 

Model climbs vertically at half throttle. You can see it in the videos.

I still don't know if I will use it as a drone with autopilot or FPV or both, affaire à suivre ...

 

Best regards,

 

Ric

If Jason's onboard view of the fly-by-wire mode in the ArduCopterMega alpha code made you dizzy, here's a view from the ground. It's really cool: you fly north-south-east-west, and the code reads the magnetometer to figure out what that means in terms of quad orientation. So you can have the quad spinning and still fly it as if it were stationary--no more worrying about orientation and where the "front" is. You fly the compass, not the quad!

 

 

Here is the test rig in Flash:

Just a reminder for those who aren't following ArduCopter development closely: ArduCopterMega (ACM) is the code name of the next version of the ArduCopter code being developed by the original ArduCopter team. ACM is based on the relatively mature ArduPilotMega code on fixed wings, and is designed for full UAV functionality (missions, waypoints, ground stations, etc). There is also great work in ArduCopter development done by the ArduPirates, but that's a different code base. Choice is good!

 

Right now the ACM code is in private alpha, but it looks like it may be ready for public beta in a couple weeks.

Announcing ardupilot Irc Channel

"For all things about amateur Unmanned Aerial Vehicles (UAVs)"Sometimes I have noticed that a lot of people (ok fine, me) make the same mistakes over and over again, Most of these questions do not need there own forum post to be reposted over and over again. So I propose a irc channel where veterans of diydrones can idle and walk people through some of the easier tasks. So I would like to invite anyone who would like to join me at:irc://irc.freenode.net/ardupilotSome popular clients arex-chat(windows)-http://www.silverex.org/news/well thats my favorite. also you can just click on this link:http://webchat.freenode.net?channels=ardupilot

Trappy's NYC flight under FAA investigation

Gary at sUAS News reports:

"sUAS News recently asked FAA Associate Administrator for Aviation Safety, Peggy Gilligan about the First Person View flight undertaken in New York by Austrian Raphael Pirker.

As Associate Administrator, Ms. Gilligan leads the organization responsible for setting, overseeing, and enforcing safety standards for all parts of the aviation industry – airlines, manufacturers, repair stations, pilots, mechanics, air traffic controllers, and any person or product that operates in aviation. These programs have a direct impact on every facet of domestic and international civil aviation safety.

We are very grateful that Ms Gilligan took the time to answer, heres what she said.

“This event remains under investigation by FAA as well as by some law enforcement organizations in the NYC area.  We do intend to notify the operator of the investigation — although I understand he is not a US citizen and we believe he is not in the US”

It will be interesting to see which particular rules may or may not have been broken during Trappys flight."

After a rough start last month, my ArduCopter CindiLou showed what she could do today. See the attached video for four flights. In the first three the camera is pointing at the Cindi, and in the fourth I have mounted the camera on the forward landing gear so you get to see a rather dramatic crash from the quadcopter's POV. The wind was blowing quite strongly to the south the whole time.

I re-read the section on GPS / altitude hold and realized that I had misunderstood how altitude hold works; that was probably the cause of the crash. I'm looking forward to being competent enough to this thing reliably and am going to repair the quad and get back to flying it as soon as possible. I'm quite happy with the way I mounted my Countour HD camera on the front the landing gear. There's no stabilization and yet the quad video is steadier than the human-captured video!

ArduCopterMega FBW mode

It still needs some work, but I thought I'd share this new flight mode. It's intended to simulate position hold using the stick input to generate a GPS offset from home. The really fun side affect is you don't need to be pointing a certain way to fly in that direction. You just point north and it flies north. To demonstrate that here is a video of ACM flying around with full right yaw. I was able to fully control it in a 5-10 mph wind even though it was spinning. The wind got the best of it for a moment there, but it recovered well. Still a little more work to do before alpha.

BOB4 - another autonomous indoor flight

Here is another autonomous flight. The UAV just tries to hold a fixed position.

Remember that this UAV is 100% autonomous with its own sensors (sonars + IMU + magneto).

The autonomous part of the flight begins at 0'09" and ends at 2'20".

I plan to take part to the IMAV2011 competition with it.

Do not hesitate to ask me question about it.

San Francisco-area fly-in today

3689388340?profile=originalWith apologies for the late notice, I and a few other DIY Drones developers will be flying in Concord, in San Francisco's East Bay, starting at 2:30 pm. Any Bay Area folks who want to spend Super Bowl Sunday outside in gorgeous weather, rather than watching a football game on TV, are welcome to join us. We'll be testing the latest ACM code on quads, and testing the latest APM code on Skywalkers and other aircraft, to check how various GPS modules behave in auto mode.

 

The location is in the large open public park at the end of Court Lane in Concord, here. Anyone from this community is welcome to join us. You can bring something to fly or just watch UAV development up close. Crashes are likely!

The Attack of the Clones

In a distant continent far far away...  Futaba clones are back on stock.

 

3689388251?profile=original

Accord to the HobbyKing site, the RX is compatible with Futaba FASST receivers: TM7, TM8, TM10, TM14 and others.

 

Some weeks ago, I bought my OrangeRX Spektrum compatible ones (main RX 6ch and the satellite).

It seems to work fine. The price... you know, is the best part.

Now is the time for the generic Futaba ones too (since October of last year).

If you have a Futaba TX and if this clone is as good as the Spektrum clone/generic ones, should be a great deal. Don't you think?

 

More details here.

T3
Hi all,
since I am doing photomapping of terrain,
I have experienced, that the light tends to change progressively as I shot photos.
The problem is, the flight is following zig-zag or spiral shape and as a result I have gradual variation
of brightness and contrast across ortophotomap.
In my case I am striving for fast response, not for HDR quality, and it might be difficult to repeat a mission
that takes up to 2h of UAV flight.
The question is, are there any tools that can linearly/gradually or maybe automatically apply some correction to a list of images?
We are talking abotu 300-3000 photos per flight, up to a few times per day. A real mill.
I am aware of ImageMagick toolset, but it is not a solution:
The problem is that any automatic method I know gathers statistics over a single image, then applies the correction to one or many.
Also ImageMagick scripts I tried to apply by merging photos etc show insufficient processing speed of Image Magick (it is general tool, with dozens of intermediary memory copies/logic layers during processing a script).
What is needed is a tool that analyses 3..tens..all neighboring images (consecutive in the list) and applies slowly changing correction.
I know that somebody will advise fixing exposition in the camera but thsi is NOT the way to go in 50% cloud cover changing the lighting 8 times during the flight.

What is needed is something like Deflicker algorithm used in movies, but this would be ideal but I doubt it exist for photos.
At the moment I am looking for anything that works.

I know the issue could be known to ppl doing Timelapses but I have no idea what are the solutions (I guess they usually merge the results into a movie, then apply Deflicker filter in movie processing soft, but the resolution, compression and quality is lost).

At the moment typical application of autobalance or histogram equalize/anything leads to photos where 1 out of 20 pops up with very off colors or other parameters.
