These are the first two ready to flight prototype picture of VR Brain Core .

70933254?profile=RESIZE_1024x1024

Are available for OEM and Beta tester different configuration of board with STM32F4 or F7 and with some additional connector like USB / SD Card or without connector that normally are available on custom distribution board.

Actually we are working at the first custrom distribution board for our VR Wasp , the ultra light complete drone compliant to under 300 gr drone for urban enviroment .

70933143?profile=RESIZE_1024x1024

This is a picture with comparison between VR Brain 5 , VR Brain Core 6 and VR uBrain 5 as you can see the design of the core is adapt for fast protyping and for simple integration inside custom design.

70933150?profile=RESIZE_1024x1024

For check the new VR Core 6 on air we decide to use this simple frame in 5 minutes we replace the VR uBrain and test the new board . 

In the video you can see the result of first flight ... It's impressive :) 

All the APM firmwware normally available for VR Brain 5 : Copter, Standard Hely , Plane , Rover , Boat it's available for VR Core. 

Here will be more information about the new OEM board : 

https://vrbrain.wordpress.com/

For VR Core there is a porting of Cleanflight by TommyLeo 

https://vrbrain.wordpress.com/quick-start-guide/speedyflight-2-31-multiwii-32-by-tommyleo/

We are discussing with Alessio Morale one of the founder of Libre Pilot project for support it inside his project.

I hope that you like this new design. It's not a replace of vrbrain and vrubrain but it's for OEM and special custom design where the integration is the must .

The board is only 5 grams

In the video I tested Loiter mode

Tested normal manual flight, alt hold, loiter and land - all Works fine

Alt hold and Loiter was impressive

In this test I used PPMSUM from my RX module

70901589?profile=RESIZE_480x480
The CTX4 quad used in the test

70901707?profile=RESIZE_480x480
T-motor 10" prop used. The motor Mounts/tube clamps have rubber rings to help reduce vibrations form the motors.

70901758?profile=RESIZE_480x480
The VR Brain Controller is separated/vibration isolated from the frame using rubber Mounts (like the ones used on many camera gimbals, but smaller and softer) + soft pads

The motors are iPower MultiMate 2012 1000kv.
When using 4000mAh 3cell LiPo I get 12-14 min before the VR Brain LiPo alarm starts.

I plan to make one more frame CTX4L (large) - that have larger motors and can use up to 12" props. Have ordered the New VR Brain 4.5 + IMU to use on this one.
On that frame I´m going to Mount my VR Gimbal Controller and GoPro gimbal.

Goodmorning everyone,
I am happy to present the first Drone helicopter completely Made in Italy :)

  • Frame Protos 500 Helicopter
  • Flight Control: VR uBrain 5
  • GPS: GPS VR 8
  • System integration by Ferruccio Vicari :)

last month of work I had the honor and pleasure to personally meet one of the developers of Italian APM Helicopter. I was intrigued by the fact that among the many cards VR ubrain sold to run multicotteri there was Ferruccio, this is the name of our Ing. Aeronautical you are 'working on to try and improve on APM Helicopter VR Brain / uBrain and also on Pixhawk He is asking us to support firmware dell'hely and our hardware to be able to get their hands on it and make performance on its means.

Ever since I met and fell in love of his helicopters in fact the lab Virtualrobotix, whenever possible, is trying to give support to his work trying to better understand how to help Ferruccio solve the current limits of both the firmware of ' hardware. Putting all this work then available Community APM.

In particular the two innovative features present in the firmware version of Ferruccio are a curve of the management of the gas 3 points that allows to associate to the management of the collective of the helicopter, the power required to fly in a simple way the helicopter. And compensation roll according to the pitch of the tail, both changes that actually make a helicopter extremely docile.

In this video you can see the video of one of the many missions that the totally autonomous VR Hely is able to do without any kind of interference from the pilot it during take-off nor on landing.
here's the video:

Questa e' una foto dell'installazione della micro brain e del sistema anti vibrante:

70931845?profile=RESIZE_1024x1024

This and 'the graph of vibration present on VR uBrain about the frame of Protos 500 and also of the solutions adopted to cut the vibrations on the flight control

70932004?profile=RESIZE_1024x1024

Another feature is the non-trivial reduces vibration and also here Ferruccio did an excellent job inventing support can cut the most 'can make vibration and actually like a normal quadricopter.
So simple that I asked Ferruccio could feel myself with an old T-rex 470 to understand how different it was to fly a helicopter over a classic quadricotteri pilot who now for years.
The result was sensational in the second flight I was completely at ease.
Surely these means are complex and dangerous, you have to have skills to do a suitable setup and then you have to use them with care but as a result of flight times with petrol engines and payload transported there 'comparison with any other type of aircraft, it VTOL plane it much less quadricopter.
The video of my first flight with the VR uBrain 4.5 on my Trex 450

And that 'my second flight, never flown before helicopters ... I would say amazing :)

Here you can find many interesting videos on its marvelous Ferruccio helicopters.

Buongiorno a tutti, 

sono felice di presentarvi il primo drone elicottero completamente made in italy :)

  • Frame dell'elicottero Protos 500
  • Flight Control : VR uBrain 5 
  • GPS: VR GPS 8
  • System integration by Ferruccio Vicari :) 

nell'ultimo mese di lavoro ho avuto l'onore e il piacere di incontrare personalmente uno degli sviluppatori italiani di APM Helicopter . Sono rimasto incuriosito dal fatto che tra le tante schede VR ubrain vendute per far funzionare multicotteri ci fosse Ferruccio , questo è il nome del nostro Ing. Aeronautico che si sta' occupando di provare  e migliorare APM Helicopter su VR Brain / uBrain e anche su Pixhawk che ci chiedeva supporto sul firmware dell'hely e sul nostro hardware per poterci mettere le mani sopra e renderlo performante sui suoi mezzi.

Da quando l'ho incontrato e mi sono innamorato dei suoi elicotteri infatti i  lab di Virtualrobotix , nel limite del possibile , stà cercando di dare supporto  al suo lavoro cercando di capire meglio come aiutare Ferruccio a risolvere gli attuali limiti sia del firmware che dell'hardware. Mettendo poi a disposizione tutto questo lavoro della community di APM . 

In particolare le due caratteristiche innovative presenti nella versione del firmware di Ferruccio sono una curva di gestione del gas a 3 punti che consente di associare alla gestione del collettivo dell'elicottero la potenza necessaria per far volare in modo semplice l'elicottero.  E la compensazione del roll in base al passo dell'elica di coda , entrambe modifiche che consentono di fatto di rendere un elicottero estremamente docile. 

In questo video si può vedere il video di una delle tante missioni totalmente autonome che il VR Hely è in grado di fare senza alcun tipo di intervento del pilota ne in fase di decollo tantomeno in fase di atterraggio.

ecco il video :

Questa e' una foto dell'installazione della micro brain e del sistema anti vibrante:

70931845?profile=RESIZE_1024x1024

Questo e' il grafico delle vibrazioni presenti sulla VR uBrain merito del frame del Protos 500 e anche delle soluzioni adottate per tagliare le vibrazioni sulla flight control 

70932004?profile=RESIZE_1024x1024

Altra caratteristica non banale è il contenimento delle vibrazioni e anche qui Ferruccio ha fatto un lavoro egregio inventandosi un supporto in grado di tagliare il piu' possibile le vibrazioni e rendere di fatto al pari di un normale quadricottero.

Tanto semplice che ho chiesto a Ferruccio di poter provare anch'io con un vecchio T-rex 470 di capire quanto fosse diverso pilotare un elicottero rispetto a uno dei classici quadricotteri che ormai piloto da anni.

Il risultato è stato strepitoso in 2 voli ero già completamente a mio agio.

Sicuramente questi sono mezzi complessi e pericolosi ,  bisogna avere competenze per poter fare un setup idoneo e poi bisogna usarli con cautela ma in quanto a risultati di tempi di volo con motori a benzina e payload trasportabili non c'e' paragone con nessun altro tipo di velivolo , ne VTOL , ne Aereo tanto meno quadricottero.

Il video del mio primo decollo con la VR uBrain 4.5 sul mio Trex 450 

E questo e' il mio secondo volo , mai fatti volare prima elicotteri ... direi incredibile :) 

Qui potete trovare tanti interessanti video di Ferruccio sui suoi meravigliosi elicotteri .

VR ESC 2.0 Tech Preview

Hello everyone,
after some years of absence from the portfolio of the esc VR, I present the new design.
We made choices very conservative to have 27 and 50 amp ESC from 4s to 6s ... we are doing tests and validations necessary because this is a very delicate component.
Here are the first photos and video of the first test.
The firmware supported are the Simonk and BHely, given the complexity of the topic we did not want to reinvent the wheel but to make a quality product that can be certified and has the ability to be installed on a dedicated distribution board.

Attached are photos and here is the video

This is the first Flight of VR Brain 5 LX

These are the picture of first drone controlled by VR Brain 5 LX 

70931768?profile=RESIZE_1024x1024

70931838?profile=RESIZE_1024x1024

After great job did by APM dev team to porting APM firmware on Linux Os our team decide to start to investigate about our design derived by standard VR Brain and ported to Linux .

At the begin we develop a board called Neuron II only as companion computer connected to uBrain as main flight controller and the linux cpu for advanced functionality as low latency video streaming. 

After some test we decide to try to merge all our experience on Neuron II and VR Brain on a single design and put inertial sensor like IMU MPU6000 and barometer on VR Neuron II  and trasform it in VR Brain 5 LX:) 

In our design we evaluate different cpu at the end decide to support RPI 2 cpu and implement on it our hardware design. 

Study and understand the new architecture and at the end we done the first real flight by first VR Brain 5 LX.  Thanks to Luca , Erik and Matteo for firmware and software development and porting and Diego for hardware design. 

In our design we mantain the compatibility with standard VR Accessories like GPS and telemetry and start to evaluate how merge the work done on Neuron II like payload managment , Professional object advoidance ecc to VR Brain LX.

These are the specification of new board : 

VR Brain 5 LX 

  • CPU Quadcore 1 GHZ ARM v7 1 Gbyte of RAM ( RPI 2 ) 
  • IMU Sensor MPU9250 
  • Barometer : MEAS MS5611 
  • 1 Buzzer Output.
  • 1 Led Output .
  • 2 Brushless motor Output ( Option) 
  • 1 aditional Imu for external Brushless Gimbal MPU6000. ( Option) 
  • 1 PPMSUM Input
  • 8 PWM Output

VR GPS Ublox Lea 6H with HMC5983 Magnetometer

 

First Virtualrobotix GPS engine using Ublox LEA-6H receiver.

This is a 50-channel high sensitive engine that boasts a Time-To-First-Fix (TTFF) of less than 1 second.

Also provide a rechargeable backup battery to improve warm start.

The dedicated acquisition engine, with over 2 million correlators, is capable of massive parallel time/frequency space searches, enabling it to find satellites instantly.

Innovative design and technology suppresses interference sources and mitigates multipath effects, giving LEA-6H GPS receivers excellent navigation performance even in the most challenging environments.

Virtualrobotix GPS uses an high efficient low noise amplifier to improve antenna signal (19dB) and a SAW filter to select GPS frequencies (see graph below).

With VR Micro Brain 5 is possible to develop very light fully autonomous drones , in last months i developed different kind of prototype the main targets was :

- Very light platform only 439 gr.

- With support of micro brushless gimbal 150 gr. 

- Support of automatic fly support with high reliability after a lot of test i   developed new kind of technology :

  • a new GPS : VR GPS 8 based on new generation of Ublox 8.
  • a new VR Leash a device for full control of drone in very simple way.
  • a new VR micro gimbal 2-3 axis based on nuttx OS with native mavlink support.

- My last target is a long time flight , the first revision of micro drone flew for only 8-10 minutes , now with last updates , new custom motor propeller and battery our time of flight is 27 minutes :)

This is the video of early version of new frame for long time of flight , need to solve some vibration problem i doing all test using EKF and APM Copter 3.2rc12 all work very well.

The next week will be present the new very nice and light frame for our Micro Brain from VR Mechatronic Lab :)
