New autopilot system from Art-Tech


Art-tech, a Chinese maker of very cheap RC aircraft, has launched a UAV division and has some new products that could be interesting.


Below are the specs of the fixed wing autopilot shown above. No pricing or availability is given (I've emailed asking for more info) and the website is a terrible broken mess of missing pages and non-working sections, so I assume the product is not out yet. My own experience with Art-Tech is that its products are pretty low quality, but perhaps this new division is aiming higher. We'll see...


Specs:


26.gifIntegrate GPS receiver, three-axis MEMS gyro, three-axis accelerometers, pressure altimeter, inertial strapdown attitude algorithm

26.gifAdopt UBLOX 5th generation GPS receiver, 4Hz output, 35 seconds fast positioning time and accuracy of 2.5 meters CEP

26.gif50HZ inner attitude control, 4HZ outer navigation control. high-precision attitude through to use 32 ARM7microprocessors

26.gifThree Modes Options:

Manual remote control, /Auto balance remote control /Automatic navigation control.

26.gifTwo modes for Ground Control Station:

Flight Course navigation mode / Mouse pointing flight Real-time Control mode.

26.gifWaypoints setting through Ground Control Station

26.gifAuto-return protection after communication interruption

26.gifDistance Automatic photography

26.gifThe ground station software contains electronic map that can change the route and tasks online,real-time semi-autonomous remote control, and can real-time record flight data and play back off-line.

26.gifContains the autopilot power supply voltage monitoring, electric aircraft power voltage monitoring, GPS accuracy of detection and autopilot temperature detection.

SpaceX Falcon 9 Achieves Orbit!


SpaceX launched its brand new Falcon 9 rocket on Friday and the flight was a complete success! SpaceFlightNow has a great rundown of the whole sequence of events and some awesome pictures to go along with it (including the one above).

You can watch the official video on the SpaceX Website - listen for everyone cheering in the background whenever the announcer speaks. I was lucky enough to watch this launch live from the SpaceX headquarters and it was one of the most exciting and electric things I've ever seen. When there's this much fuel and power involved there's little room for error so seeing it fly away without a hitch was truly exhilarating!

Later when it flew over Australia many mistook it for a UFO : )

Updated site policies

[I've just updated our site guidelines. Here's the new text]

DIY Drones is community site focused on amateur aerial robotics. Our aim is be a place where people can learn, teach, exchange and participate in projects and events. We aim to be as welcoming to those just starting as we are useful to experts. Our culture thrives on collegiality, sharing and openness.

We have many volunteer moderators who have admin rights to ban members, delete posts and otherwise do their best to maintain civil discourse and a high signal-to-noise ratio here. They will also encourage good behavior and guide people to get the most out of the site. Here are our policies, which the moderators are charged with enforcing:

1) Civility is paramount. Treat others with respect, kindness and generosity. Some of our most expert members are people who were once total n00bz but were helped and encouraged by others, and are now repaying the favor with the next generation. Remember the Golden Rule.

2) No discussion of politics or religion. This is not the place to discuss your views on the wisdom of military use of UAVs, any nation's foreign policy, your feelings about war, or anything else that is inclined to turn into a political debate. It is our experience that the rules for good dinner party conversation--no discussion of politics and religion--apply to online communities, too. DIY Drones aims to bring people together, and we find that discussions of politics and religion tend to polarize and drive people apart. There are plenty of other places to discuss those topics online, just not here.

3) Ask questions in the discussion forum; inform others in blog posts. Submitted blog posts that are just questions and should have been posted in the discussion forum will not be approved. The moderators may or may not message you with the text so you can repost in the right area. To avoid losing your post, put it in the right place from the start.

4) Blog posts are for informative topics of broad interest to the community. They should typically start with a picture or video, so that appears on the front page on the site and gives a sense of the topic as well as inviting people to click in for more. Videos should be embedded (paste the embed code in the HTML tab, not the Rich Text tab). The post should also include links where appropriate. Don't make people do a Google search for what you're talking about if you can provide a link.

5) The Discussion Forum is for questions and tech support. We prefer to do all tech support in public, so that others can follow along. If you have a problem, please describe your particular system setup completely, ideally with a photograph, and pick the right forum tags so that others can find the thread later.

6) No discussion of military applications of UAVs. This site is just about amateur and civilian use.

7) Do not type in ALL CAPS. It's considered SHOUTING. Posts in all caps will be deleted by the moderators.

8) Absolutely no personal attacks. It's fine to disagree, but never okay to criticize another member personally.

9) Share. Although we are not limited to open source projects, the ones that tend to get the most participation tend to be open source. Don't wait until your code or design is "finished"--post it as it is, and you may find that others will help you finish it faster. The best way to contribute is with your creativity--we love data, code, aircraft designs, photos of UAV projects, videos of flights and build logs. Post early and often!

I've been a bit careless about updating the blog regularly but here it is finally! I've posted some videos and pics of our CNC cutting some wing molds as well as the antenna gimbals. There are also pictures of the mold layup process, gimbal mechanics and new CNC setup. Please find the full article here:


http://www.projectandromeda.com.au/blog


I've also finished the first revision of the IMU, and written a simple simulator in the GS to figure out any bugs on the Autopilot. I will post some shots and videos of these tomorrow. Also, we are officially an entrant in the 2010 UAV Outback Challenge!

3D Robotics

HappyKillmore has been doing some tremendous work on solving tricky ArduPilot problems, from integrating the Remzibi OSD to his latest tutorial, unbricking a corrupted ArduPilot.


ArduPilot is meant to be programmed via the Arduino IDE, and comes with a preloaded "bootloader" that allows it to communicate with that software. Meanwhile, the failsafe processor (an Attiny45) is not meant to be programmed by regular users at all (it also comes with the code loaded at the factory).


But sometimes things can go wrong, corrupting either that bootloader or the failsafe code (causes can range from power glitches to cosmic rays!). When that happens, you need a different process to reload this low-level code, and that requires an AVR programmer such as the AVR ISP 2.


HappyK's tutorial is an excellent step-by-step illustrated guide on how to use that with ArduPilot. Highly recommended!

ABOVE NAPA FINALLY, MARCY 1 SHOTS

GRIP TAPE TERRORISM



So found out the reason for the sudden flip during NAPA flight #1. Noticed on NAPA flight #4 the grip tape was slipping & managed to save her to see the grip tape completely loose on the ground. Unfortunately an attempt to reinforce it with duct tape failed & she crashed hard on NAPA flight #5 with the propellers having slipped forward & with the pilot assuming they were slipped aft, ramming Her into the ground at full power.









Fortunately the new camera mount had enough give to break before the
camera.

The grip tape binding round CF rods to the fuselage loosened in warm
weather & the only warm weather we flew in was NAPA. There was no way
to detect this problem without already knowing temperature could be a
factor. So grip tape is no good. There's a lot of torque on those CF
rods. Double sided mounting tape is the only thing that works, as
stretchy as it is.

ABOVE NAPA

Before the crash, finally snagged the flight which ended in failure previously.
Need another trip for video.






















Some final mane shots before it's cut off. If Major Marcy was just a stranger, we weren't similar ages, & saying we look damn old didn't evoke eternal damnation, fire & brimstone for all time so help us God because of the negativity over Her age, we would say we look damn old, but we didn't say that.


The camera was shooting video this time & got some of the breakup. Unfortunately a few frames were still in the cache when the power was cut. She missed a water tank by only a few feet.

















On to what must be her 10th fuselage.





3 batteries of hover testing.



This golf course is under Air Force control.

Made a 1st attempt at photographing Marcy 1 in flight. Best results
were using F: 2.8 shutter speed: 1s ISO: 400 Flash: 1/16 Focus: 3m
Air Force logo doesn't come out very well.






















There is a way to smile, but it requires looking at something which
makes you fall in love.

Magnetometer primer

A nice intro to magnetometers from Sparkfun. A bit basic, but good if you've never worked with one before.

"If you're building an autonomous vehicle or a hand-held GPS (or any other device where direction might be important), a digital compass (sometimes called a magnetometer) is a great little sensor to add to your design. However, if you haven't played around with them much, you might not know which type of compass is good for your specific project (for example, do you need tilt-compensation?)."

We also sell one optimized for UAV/ArduPilot use here.

Google Earth UAV/FPV Flight Model


In between school and work tonight, I decided to try out the Google Earth flight simulator mode. It looks like the joystick issue I remember it as always having has been fixed in the most recent version, or at least, for the Saitek Cyborg Evo series.

I decided to try modifying the .acf file that configures the "aircraft". This file is located in (Root Programs Folder)\Google\Google Earth\client\res\flightsim\aircraft . I modified the F-16 file to approximate the flight dynamics I usually get when doing my FPV flying wing.

Probably not too useful for autonomous UAV research, but it provides a fair approximation of what flying from the front seat is like without having to actually go flying FPV. Fun for practicing for FPV as well.

The file I modified is this: f16.acf

Just replace the current existing F-16 file of the same name in the folder path mentioned above.

It is a neat little package, but I'm not sure it garners Engadget coverage...

http://www.engadget.com/2010/06/03/cheap-tiny-camera-for-rc-planes-captures-video-proof-when-you-b/

- I just looked at the whole thing..it just records and stores, has a USB output on the back. Might not be too bad as a pylon or external mounted recording option...records VGA at 25fps on to 2GB of internal storage.

ArduCopter Frame development

We all are working hard to get this done as soon as possible. And as relief the pain of wait, here are some previews of new ArduCopter frame designs for the masses to look and to comment.

Current design will have two center plates like most of multirotors have, it also have carrier boards to carry electronics like APM, APM shield and Receiver. Another carrier board will be mounted under main frame to be as a battery holder it also creates supporting base for future landing gear addon.

It's been planned to have a power distribution board above center plates.

Square center plate having X setup, it also holds + setup on this board


Center plate with carrier board. Carrier and also power board (not shown) can be rotated with 45° steps on all designs. Power board will have 10 mm spacers and carrier 20 mm.


Square frame with carrier (rotated +45°) and power board.


And last but not least round Quad/Hexa center board. Quad power distribution included. Both carrier and power boards can be mounted either above or below center plates. They also fit on both square Quad plates and round Quad/Hexa plates.


We are closing finishing line so not any major changes should happen. Tho this is still preview on what we have been working behind the scenes.

First frames are being build as we speak..

I will post more pictures on development wiki https://code.google.com/p/arducopter/ during new couple of days.

Cheers,

Pteryx flight over Bezmiechowa mountain.

image018.jpg
The map depicts unusual, sloped glider airfield.
It was a small demonstration for the officials.
I wasn't even there, just posting my friend's flight.
http://www.pteryx.eu/bezmiechowa-overlay-2010-05-29.kmz
http://www.pteryx.eu/bezmiechowa-stitch-2010-05-29.jpg
The stitch is a hasty drag&drop into Microsoft ICE.
We are surprised how well it fits into the sloped terrain
given the lack of effort from our side to make it exact.

Heli UAV progress

I got working on the kalman filter and adaptive control system for the swash. I designed a board for the XMOS XC-1A dev kit for prototyping before a final board is designed.
Right now, the board supports 6 servos, 3 gyros, a 3 axis accelerometer, the EM406A, the HMC5843, and the SCP1000. A 6 pin expansion header can be configured into anything digital, from UART to I2C to PWM.
I received a Century Swift 16 that will be used as the platform, The pictures have the 1W 900mhz transmitter module for scale (4"x1.5").

New GPS satellite launched


From the Google Earth blog: "Last week, the U.S. Air Force launched a new satellite (the GPS IIF SV-1), the first in a series of launches aimed at replacing all 24 existing satellites over the next 10 years.


These new satellites offer a variety of enhancements over the existing ones. The most important part of this project is to simply replace them. Numerous reports are concerned that the existing network may begin to fail due to age. This will obviously remedy that. In addition, these new satellites will provide a stronger, more accurate signal. Rather than the roughly 20 foot accuracy that you currently receive, the new ones will allow for accuracy down to about 3 feet. In addition, the stronger signal will help more GPS units to function properly indoors, which could be a big boost for various augmented reality tools that are beginning to find their way into the marketplace. The launch of the next satellite (GPS IIF SV-2) is scheduled for November, 2010."

AttoPilot RTL version available

I'm not sure how long this has been out, but I just noticed it. AttoPilot has a RTL version available that is not export controlled. The website says the site is under construction and the product listing still has a lot of typos, so this may just be a preview. (It's not listed on the order form, so I'm not sure how much it costs or how to buy it). It appears to be a stripped down AttoPilot 1.9 with the mini-SD card reader glued on top of the airspeed sensor, but there may be some other changes. For comparison, the regular AttoPilot board is shown below:



Dean Goedde has done a great job with the AttoPilot line, so it's very good news that a RTL version is now part of it. You should expect rock-solid performance and a relatively easy setup procedure. Now just waiting to hear about pricing....(I've pinged Dean to ask)
