A small testimony of "Italian industrial archeology " some company try to resist . Now that everyone thinks that is possible to produced only in china ... Italian Makers say No! You can 'and you must try to do something more here in Italy !! Virtualrobotix is a farmless company , so we use small company near us for going in production or some great partner around the world :) There's the little mounting backstage box of VRBRAIN
The first test was doing by a 3d printer but for produce a pcs it need 4 hours ... with a molder only 30 sec for 4 pcs ...now i need to sell it :) Help me to solve my problem ;)
Hehe, just a teaser for my yesterday's tests on VRBRAIN with latest 2.9 firmware! VRBRAIN uses the powerful ARM STM32F4 CPU and runs with the actual 2.9 firmware codebase.
So while we are upgrading the code to the new AP_HAL_xxx standard I finally took some time to test our recent port of the Arducopter 2.9 code, still based on the old code standard.
I have also set up a small and rather incomplete "how to" to upload the firmware into the STM32F4 ARM Microcontroller
Man!, never had so much fun with the Auto mode! I am using a UBlox GPS on a Hexa frame with 10x4.5 APC props.
The main difference between our code and the original Arducopter one is that we drive our main stabilization loop at 400Hz (instead of 100Hz) and get samples from the Gyro and Accel at 1000Hz (instead of 100Hz) with only 10% CPU time used.
The filter of the MPU6000 is set to 98Hz, although the Alt_Hold with the accelerometers worked very well.
Some perf mon :
VRBRAIN @ 2500Hz-400Hz
Function: cpu avg(ms) max(ms) Hz
fast_loop 10.31 0.257 0.325 400.0
fifty_hz 0.20 0.040 0.093 50.0
gcs_check 0.16 0.004 0.118 350.0
update_GPS 0.07 0.014 0.105 50.0
medium_loop 0.04 0.007 0.029 50.0
super_slow 0.02 0.189 0.277 1.0
slow_loop 0.01 0.012 0.032 10.0
free CPU: 89.17 8922
Here is the picture of the Waipoint path, as you can see I am not good in drawing, but the path was followed very well.
One thing that impressed me was the alitude, in all the auto mission only 1 meter between max and min.
The new altitude hold with use of accels is doing a great job also in autoland and auto-approach.
To all the AC team a big thanks for the huge work!
And thanks to Roberto and VirtualRobotix for his VRBRAIN!
Hi VirtualRobotix! We met you at Modena Makers, it was a very interesting experience, we had the opportunity to see your amazing technology!
We present you Axemblo, the new open source construction system for professional DIY Robotics. Axemblo system is based on Aluminum, a lightweight, ultra-resistant and recyclable material. With Axemblo you can create fantastic Robots, Rovers, mechanical arms and supports for Electronics Boards (VirtualRobotics board fits perfectly).
Axemblo is released under a Creative Commons Attribution-ShareAlike 3.0 Unported License to enable students, researchers and the community to expand the system. Looking forward for a collaboration with you. We would also love to hear from the community it would be very useful for us to know what they think about our system.
In these months Virtual Robotix community present in italy our Drone tecnology , this week was in Modena and present VRBrain and last revision of Arducopter32 rev 2.9 .
In our stand we had a lot of peoples for two days and we was more success also respect of presentation of 3d printer :)
At these link can you see the presentation of VirtualRobotix at Modena Makers this week 19-20 January 2013
Our target is traver around Italy first and then the other country in europe to enroll new developer and present the great work doing by developer of our community .
The new Arducopter 8-32 bit firmware have a lot of great new functionality and is incredible that all this work is Opensource , when we explain this concept to the peoples that we meet in these events thy are very surprise.
Congratulation TEAM :) We are doing great work !!!

http://www.guardian.co.uk/uk/2013/jan/16/helicopter-crashes-central-london-vauxhall helicopter crashes in London at 08.40 ! of course it doesn't happen every day that an helicopter crashes right in the middle of towns ! BUT thinking to Unmanned which we would like to free operate, to the severeal configurations available on the market, to operations carried out as often is seen in YouTube or others social netowrks dedicated to amatorial unmanned it is once more demonstrated that a type certification is a MUST for security of all and for the future of the sector, being that Unmanned for civilian applications are requested to fly right in the middle of our town for surveys, above people for events etc...
