Today Marco doing a great test with his Hexa and VRBrain he used firmware Arducopter32 2.9.2b developed by official DIYDRONES Team and ported on VRBrain and supported by VRI Lab Team.
The Dev Team doing a great work :) The main advantages of VRBRain is that is 30x faster of standard APM 2.5. The main difference is processor: VR Brain use STM32F4 168 mhz and integrated FPU . APM used a standard AVR 8 bit processor at 16 mhz.
On VRBrain the scheduled time task is respected at 99% , we have 80 % of cpu time in idle and 3/4 flash free for future development of firmware and 1 year of test by our VRI flight team.
With this feature you have a great smoth flight and the attitude is processed at 500 hz , sensor is update at 1 khz instead of 250 hz in APM 2.5.
In this test the VRBrain is controlled directly by AndroPilot. The application is available on Google Play and supported by Android 4.x Pad and Smartphone.
The AndroPilot is connected to VRBrain by 3DR radio telemetry module directly connected to USB port of ASUS Pad.
In video is possible to see the guided mode and Follow me functionality available on AndroPilot application.
The AndroPilot use internal GPS Pad for position of Marco and send every some times and when Marco move the new point to drone that follow Marco during his travel in the field.
I think that this result is very impressive . The integration of different technology is developed very good , It's only an early stage prototype but the result is yet very good .
The board use by Marco is VR Brain 4.0 with enclosure and 3DR Ublox GPS the quality of fix is very good.
Thanks to Marco , Emile , Randy and the other guys of devteam for this great result. Thanks to Kevin for his great CGS Android Application Andropilot.

Kevin, thank you so much. I tried Guided Mode today using AndroPilot following your instruction. This Apps is awesome and it's pretty simple after all. I also tested for the first time Loiter, Alt-Hold, RTL and Disarm functions. Wonderful! I salute you guys for the job well done.
Hi guys, i want to test Guided mode on my Quad using my tab...What's the correct procedure? Do i have to fly my Quad on stabilize first, then point on my tab specifying height? Or do i have to switch to Guided Mode on my Controller first? I have done waypoints using my tab and it was sucessful. Thanks.
Done!
Sure, thanks Kevin but... which one?
The sound when i touch the screen or the other one (maps error)?
@Kevin
what kind of info do you need about VR Radio ? What Pointer ? Do you need a class description ?

Robert, we have a version with the AP_HAL that we will ask to merge soon in the Arducopter repo.
We still need to fix a few small issues with radio, all the rest is 100% compatible and you can find it in the ap_hal_newdir branch: https://code.google.com/p/vrbrain/source/browse/?name=ap_hal_newdir...
By now the toughest and most reliable code is still a port of the 2.9.1 with some 2.9.2b integration.

Kevin you can find it here:

I love the follow me mode. Hey Kevin, if you want to check out our gamepads, drop me a note - I work for MOGA (we make a Bluetooth gamepad for Android that does SPP using our SDK as well as HID). Be glad to send you one.
Hi Robert,
if you want download our enviroment and compile the VRBrain code is simple ... you can found this link :
http://vrbrain.wordpress.com/installing-and-compiling-the-code/
We yet prepare ready to use .dfu file for our user so you need only st tools for upload by usb the code.
The enviroment that we use is called VR Universal Ide is a ready to use enviroment you need only download the eight file and unrar in a directory that going inside and execute eclipse .
Could be good put in a short name directory the enviroment as C:\job for example we see that if you put the enviroment on desktop you can have problem with the lenght of file name.
If you need support can ask to me or Emile in skype my account is : virtualrobotix
@Marco yes Robert is the best for check VRBrain on a helicopter ... ;) @Robert if you need a board is available :)

So we can just compile Master for VRBrain now, using that hacked version of Arduino they cooked up? I'm behind the curve on this stuff. On the PX4 I just uploaded using that fancy new thing on MP where it grabs the latest.
