Flex 4 GCS Update


This should have come out yesterday but admissions essays got in the way. Anyway, I updated the GCS, and now it supports waypoint-ing by clicking on the map. You can also insert waypoints in between existing ones by using the Add Before/Add After buttons. Delete waypoints by using the shiny red button.

To set up options for takeoff and landing, click "Takeoff / Landing Options". You'll be shown a screen like this:


... where you'll be able to set the takeoff pitch and altitude, as well as add CMD_LAND_OPTIONS entries. Fill in the boxes and click Add Landing Option, and it'll be automatically added to the list. The list is held in sorted order. To delete an option, select it and hit the 'Delete' or 'Backspace' keys on your keyboard.


Finally, You can export your mission to a waypoint writer file. I've only exported to the mission[][5] array, so you'll need to create the file and then copy and paste it in.



If you're using the GPS Simulator with this, and suddenly see the CDI (lowest instrument on the left) needles suddenly jerk around, just ignore it for now. I'll add in functionality so that the CDI will show your deviation from the plotted mission soon.


The updated .AIR file can be found here: http://zhiquanyeo.com/apm-gcs/APM_GCS_ControlStation.air


Have fun and as usual, let me know if there are any bugs, or comments :)

JYNX Depron Made Glider


DSCN4355.JPG


JYNX 4.0: This is JYNX glider designed by RCPLANS.nl . Now a days I am working on it and modifying it for electric motor powered. I am attaching whole plans of this glider. Totally made of depron foam and low cost plattform for APM.


The JYNX is a depron flying wing glider, designed for sloping. It's a simple build, which took me a week to finish in the evening hours. The JYNX has a 15% symmetrical airfoil, which is created by folding the wing from the leading edge around a depron spar. there are no carbon fibre reinforcements used, yet the wing is very strong and stiff. This plane is light on the budget too, as it uses just two cheap 5 gram servo's, a 4 channel receiver and a small battery.So far the prototype has flown a few hours, in which I've experimented with the center of gravity, control throws and reflex. You can find the results on the plan. Keep in mind that reaching the indicated center of gravity will mean you have to place the receiver and battery at the back of the fuselage.The JYNX has had a good number of pretty rough landings, but I haven't found a single scratch or crack. This is a very durable plane.Finishing has been done with clear packing tape used for masking, acrylic paint applied with a brush, and a dry paintroller to absorb and spread the paint. The results can be compared with airbrushed paint.The available space in the fuselage is quite limited. I'm still working on a version with a brushless motor, and might release a new plan for a slightly bigger fuselage soon.

Preview of my wireless modem development



Here is a preview of my long range wireless modem.

It's based on a Radiocrafts 868Mhz module (RC1180HP) with 450mW RF output power and good receiver sensitivity.

I'm going to use this for modem telemetry and antenna tracking, one in groundstation and one in the airframe


It has the following features:

1x LCD 102x46dots

4x Buttons

1x MicroSD slot

3x analog to digital inputs

1x I2C

1x SPI (if LCD is not used)

1x RS232 (TTL)

2x Timer outputs (used to connect a 4017 to drive servos)

4.5 to 32volt DC input

Dimensions are 44mm x 55mm x 5mm


More info will be added later.....and yes it will be open-source, I will share all design info if you want....

Edit:

Here you can find the schematics: RC1180HP-Modem.pdf

Book recommendation: The World's Worst Aircraft

I noticed this book on the bargain shelf of Barnes and Nobel and picked it up--I haven't been able to put it down since. It's a terrific romp through 150 of the worst aircraft designs in history, but what it really is a catalog of all-too-common engineering errors, such as:

  • Solutions looking for problems (such as jetpacks and the Hillar hovering sniper platform)
  • Engineers designing planes with no sense of what pilots wanted
  • Dependencies on exotic fuels that aren't available
  • The "Gillette problem" of adding more wings than the last guy, including some crazy 8-wing things
  • Delivering so late that the need is gone.
It's beautifully illustrated and very funny, thanks to the sparking writing of Jim Winchester. And the stories are hilarious. Here's my favorite passage, about the ME 163 Komet, an experimental German rocket plane:

"The fuels in the Komet were highly corrosive and would dissolve organic material (such as the pilot). To avoid this, the pilots would wear special asbestos-fiber suits"

Kill you now or kill you later ;-)

Highly recommended!

New report on China's booming UAV industry

China’s WJ600 Jet-Powered UAV

From my email, a promo for a new market research report. No doubt very expensive, but it's interesting (and appropriate) that China's UAV industry is finally being taken seriously. Those who think that the Chinese UAV companies are just cloning Western designs are badly out of date.

From the email:
"As predicted in the two most recent Market Intel Group (MiG) technology and market forecasts on Unmanned Aerial Vehicles (UAVs), China is pushing aerial drone research and development aggressively. That is also the conclusion of a recent Wall Street Journal article on a major Chinese air show


Market Intel Group’s research reports, titled: “Unmanned Aerial Vehicles (UAVs) for Counter-Insurgency – Market & Technologies Outlook - 2010-2015” and “Unmanned Aerial Vehicles (UAVs) for Border Security – Market & Technologies Outlook - 2010-2015.” identify regions, applications, strategies and types of platforms that will lead the rapidly emerging Counter-Insurgency and Border Security UAV markets worldwide. As part of our analysis, we identify China as one of the more aggressive and unpredictable entrants into the heated UAV market.


The WJ600 pictured here is offered as an example of recent Chinese development that is designed to position this country’s UAVs at the forefront of this competitive market. Jeremy Page, in his WSJ article, writes: "China is ramping up production of unmanned aerial vehicles in an apparent bid to catch up with the U.S. and Israel in developing technology that is considered the future of military aviation.” MiG assumes that China would sell UAVs to nations boycotted by the US and Israel. Such an assumption was also confirmed in a round-about way in this article. Page quoted a Chinese official who told him: "I can't tell you which models we have sold overseas, as that's secret, but of course we're interested in exporting them." Since UAV deployment information is mostly public domain, as well as a major marketing tool for competing vendors, keeping information about deals under wrap points to the possibility that such deals were made with countries that current major UAV vendors are reluctant to do business with.

MiG’s new UAV reports analyze, among others, Concepts of Operation, platforms, payloads, evolving markets and applications, allocations, procurement patterns and resultant changes in the rapidly evolving UAV industry worldwide."

Hi Everybody! It's me again. I am glad you enjoyed the Flying Ghost I made for Halloween. We decided to do another video for Thanksgiving. This is our remote control, flying, quadcopter turkey. It flies, it drops pies. Pretty much all you could ask for. (I tried to up the production values on this one as well.)

I really hope you guys find it entertaining! Thanks!

HappyK GCS in the field (very bad video)


Some of the APM dev team were enjoying the spectacular Northern California weather today, testing various APM navigation functions. But it was also our first chance to test the awesome HappyKillmore GCS in the field. It worked great! The "chase cam" view on the moving map is particularly cool. Sorry about this terrible video, but shiny laptop screens and the bight California sun don't mix.

Uhm.. another GCS???

"3689379691?profile=original
Uhm yeah hi, I'm ZQ, long time lurker, first time poster..."

Well, this is what happens when a recently graduated grad student gets bored, likes aviation and is trying to learn a new language/framework. So, here's some looks at a GCS for APM written in... *shudder* Adobe Flex 4. Before I get slammed, the only reason I'm writing it in Flex 4 is because I'm planning on using it for some other projects and need to get used to it, plus with Adobe AIR, it can run on desktops. (That and I have a slight aversion to C++).

The instruments are configurable (e.g. you can change the speed ranges on the ASI, etc), and it uses google maps for the waypoint system. It'll support (eventually, once I finish writing it) all the commands present in the APM command list. Communication can be done over serial, with the use of serproxy (as Flex/AIR doesn't have access to a serial port directly). I'm also planning to add a vertical profile plotting capability to the GCS, but that will come a little bit later.

Additionally, I whipped up a GPS/IMU simulator in Flex as well, to test out the packet communication and position plotting on the GCS. The simulator allows you to plot waypoints, and select an update rate, and it will broadcast position, speed, altitude and IMU information in APM binary format over a network connection. You can also connect multiple clients to the GPS Simulator and they'll all get the same information.

So without further ado, here are some screen shots, and I'll update more shortly (and put up .air packages if there is interest).


GCS Screen (Still a bit empty right now)


GPS Simulator


What happens when you want to see interesting patterns



Installation Instructions:

Download the .air files from:

http://zhiquanyeo.com/apm-gcs/APM_GCS_GPS_Emulator.air

http://zhiquanyeo.com/apm-gcs/APM_GCS_ControlStation.air


You will need the AIR 2 runtime available from http://get.adobe.com/air/


Usage:
Start up the waypoint simulator and click to add waypoints. The delete and add before/after functionality doesnt work yet (oops). You can click on a waypoint on the map or in the list to select it and change the altitude. Waypoints are draggable on the map.

When you are ready for clients to connect, enter the port number you want in the textbox and click "Start Listening"

Start up the GCS and set up the correct port number in the box. Then click connect. You should see "Connected!", otherwise check your port settings. Then click "Start Simulation" in the GPS Simulator and watch the fun happen.

Note: The menus don't work, and things might be prone to breaking (cos.. you know, grad students are horrible coders). If you find any bugs or crashes, let me know and I'll add them to my (ever-growing) TODO list.

Creepy/Cool Animal Inspired Robotic Designs


Festo is a German robotics company promoting a number of weird and wonderful robots inspired by nature. My personal favorite is this particularly unsettling elephant trunk - brings to mind sentinels from The Matrix et al.

From Singularity Hub: "Robots are ripping off nature! …Good idea. Festo, a multinational robotics firm based in Germany, has made some of the most amazing looking and fun biologically inspired robots out there. We’ve shown you their Air-Penguins and their Elephant-Arms but there are so many other Festo creations yet to be seen. Luckily, the robotics company seems to be going through their back catalog, and they just released videos of their research efforts from 2006 to 2008. These bots may be a few years old but they are absolutely cool to watch. Check out the Air-ray, the Bionic Air-fish, the Aqua-jelly and more in the videos below. Why do I get the feeling that Festo is building the robotic equivalent of Noah’s Ark?

Nature is one of the best engineers around, so it’s no surprise that some of the smartest robot experts are looking to biology to inspire their innovations. Festo is one of the world leaders in automation, with millions of parts installed in factories all over the globe. Their animal inspired robots are created by the efforts of their Bionic Learning Network. This collection of research groups from academia and industry is part advanced research initiative, part education organization. While many of their bionic bots have practical applications, they definitely seem willing to explore far off the beaten path even if there’s not much monetary incentive. That’s totally fine by me. I love the grace with which their robots fly through the air and water, and I can’t wait to see what they copy from nature next. Hopefully they’ll stay away from the predators of the world. Sharks are bad enough, but robot sharks? That would just be asking for a robot-apocalypse.

The first video is a little long, so here’s a guide:
1:30 Air-ray
2:20 Bionic Air-fish
3:05 Humanoid
4:56 Air-acuda
5:48 Aqua-ray





The next video recaps some things from the first. Go ahead and skip to 1:14 to check out the Aqua-jelly.



Here’s more of the Humanoid, so you can see how all of its pneumatic muscles move and work.

HexRotor

Came across this in the Science Museum London as a development by Manchester University. It looked like the motors are fixed at this angle - Why? Anyone suggest any benefits for this arrangement - faster yaw control? greater stability? more controllable?

Developer

The SCORPID-500 is now fully stabilised and controlled by a 9 DOF IMU (ArduIMU+ v2, HMC5843, GPS with firmware TriStab v3.3 JLN). The SCORPID-500 VTOL UAV uses an innovative design based on Gary Gress concept from Gress Aero. The Oblique Active Tilting (OAT) at 45° of the twin engines allows a full pitch control by using the induced gyroscopic moment. Today, the SCORPID-500 UAV prototype has done its first successful flights full IMU stabilised. Its flight is very stable. The earlier prototype has used 4 gyroscopes on board and some addtionnal mixers.
