Un saluto a tutto il gruppo e un ringraziamento a Roberto per l'ospitalità

Da circa 2 mesi sto lavorando ad un progetto di un multicottero che ho battezzato ArmQuad

Le caratteristiche sono:

Processore: ARM7 32Bit LPC2103 a 60Mhz

Gyroscopio: ITG-3200 triplo giroscopio da 2000°/s, interfacciamento I2C, 16bit, vari tagli di filtri passa basso selezionabili via software,sensore di temperatura integrato

Accelerometro: BMA-180 triplo accelerometro , interfacciamento I2C, 14bit, vari tagli di filtri passa basso, passa alto, passabanda selezionabili via software, sensore di temperatura integrato

Regolatori brushless: PWM commerciali pilotati a 450Hz

RX: è necessario un ricevitore con uscita seriale dei canali radio o in alternativa un convertitore parallelo / seriale da aggiungere ad una RX con uscita standard.

Tempo di esecuzione del ciclo loop completo con la configurazione attuale : circa 500microsecondi, 2Khz

La mia filosofia di costruzione e' di tipo step by step, si passa allo step successivo sia hardware che software soltanto quando lo step in corso e' terminato e funziona in modo ottimale oltre che sulla carta anche nei test di volo reale, questo consente di non trascinare eventuali errori hardware/software negli step successivi.

Dopo aver effettuato il primo volo utilizzando i giroscopi presenti all'interno del wii motion plus, ho deciso di impiegare i sensori sopra riportati, la routine di volo iniziale era la modalità ACRO, basata sul controllo retroazionato della velocità angolare.

In questi giorni ho integrato l'accelerometro e sto quindi testando la modalita' "autolivellante / stabile" basata sul controllo dell'angolo.

I prossimi upgrade saranno l' utilizzo di un ARM M3 Cortex a 100Mhz, l' integrazione di barometro i2c, compasso magnetico i2c e GPS per la navigazione a waypoint

Sotto video del primo volo e alcune foto, i cablaggi sono ancora approssimativi in quanto mi trovo in piena fase sperimentale.

Saluti,

Danilo

Hi All,

this is my experimental project of a quadrorotor, ArmQuad:

ARM 7 32bit LPC2103 a 60Mhz

ITG-3200 Triple-Axis Digital-Output Gyro, 16bit, digitally-programmable low-pass filter

BMA180 Triple Axis Accelerometer, 14Bit, Programmable integrated digital filters

ESC: PWM at 450Hz

R/C RECEIVER: PPM composite signal

CONTROLL LOOP EXECUTION TIME with the current configuration : 500 uS, 2 Khz

After the first flight using the Wii Motion Plus in ACRO mode now I'm testing the angular control mode, the next updates will be:

ARM M3 Cortex 100Mhz

Barometric Pressure Sensor

Compass Module

GPS and waypoint navigation

Regards

Danilo

Indoor flight doing by Emile , Stefano , and Flavio during Model Expo Italy 

In the first video is possible to see Emile and Flavio that doing an indoor flight with VRBRAIN firm rev 2.9.2 .

The second flight is doing by stefano with ultra light full carbon frame VR Special Drones.

Official Video by Mediaset : http://www.striscialanotizia.mediaset.it/video/videoextra.shtml?12757
This video was produced by Italian Television . Some people inform the autorithy about the presence of ufo in the sky of Naples in Italy ... , But a Napoletan member of FOXTEAM http://www.virtualrobotix.com see the trasmission and identify in that ufo his quad .. that use Multipilot .. ;) So he called The Gabibbo and explain that The UFO isn't extra terrastrial , but An Italian QUAD .. ;)

Best Roberto.

P.S.

Great Job Pippo  ... another X Files is Closed :)

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

http://www.virtualrobotix.com/photo/albums/modena-makers

And last Presentation of 2012 at Makers Italy :

http://www.virtualrobotix.com/photo/albums/makers-italy-i-corsi-di-virtualrobotix-com

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 !!!

The Armfox V4 is my experimental platform for develop Flycam .

In my development i'm using :

Multipliot 32 :  http://www.virtualrobotix.com/page/multipilot32-1

VRIMU : http://www.virtualrobotix.com/page/vr-imu-10

VRI2C ESC: http://www.virtualrobotix.com/page/vr-bl-controller-10

The firmware is ArdupiratesNG 32 that i had implemented with some new libs and functionality :

I add the support to 1 wire PPMSUM radio as Jeti to have on 1 wire until 12 channel that could be usefull for fly cam application .

I add the support to i2c esc so the refresh rate of esc is 2.5 khz instead of 550 hz available on standard esc.

On VRIMU is available a professional sensor ADXRS 610 gyro for high precision and high immunity to vibration. the full scale of sensor is 300 °/S and the resolution is 12 bit.

With this kind of configuration is available a lot of 16 bit pwm output for manage high quality sensor for gimbal managment.

Dear Friends,

today i recived 100 Multipilot32 CPU , in the next day will start to ship the Multipilot32 to DevCoreTeam and customers that are wayting it.

I'm very happy to start to work with your help at this greatfull project.

Tomorrow will present and discuss with you official roadmap of project. If you want to join us will be online with a Online Seminar from 22.00 (CET) Rome TIME.

Thanks for your collaboration :)

Dear Friends,

two years ago i developed a closed source Brushless Controller. It's based on ATmega 8 and support i2c,PWM,Serial Port. The ESC support until 20 Amp and the electronic is present a shunt resistor to evaluate the quantity of energy that the motor need in realtime.

So now I would to port a Arduino bootloader to this board and develop an  opensoure code for it.

But i need help  for this project ... There're some people that would join me in this project ? That's is good choice for Multipilot 2.0 / Ardupilot 32 platform.

Regards

Roberto

Dear Friends ,

the 07/04 will doing a online webcast where we present last updates of Multipilot32 project.

Dear Friends,

after some time of evaluation of software architecture for Multipilot32 I decide to put on it a Real Time Operating Systems.

Instead of choose FreeRtos or other clone . I found  this interesting operating system that yet support HAL .

Above there's an introduction of Chibi OS , what do you think about ? My idea is to rewrite the lib of our Arducopter project using a professional approach with a Realtime Kernel on low level OS call.

A video of Chibios User that develop his quadcopter ... :)

I'm waiting your feedback :)

This is official Discussion Thread : http://www.virtualrobotix.com/forum/topics/multipilot32-need-a-rt-os-what

Chibios Introduction :

This document will help you understand what ChibiOS/RT has to offer in a world with so many similar products.

Why another RTOS:

No error Condition.

Very Simple API.

Fast and Compact.

Test and Metric.

Hexacopter version or ArduPiratesNG code with GPS position and altitude hold, and ultrasonics low altitude hold.

More crazy stunts, including flips, in acro mode by Warthox

As always, follow the ArduPirates Vimeo channel for all the latest videos.

Try to use your Iphone on this Magic Box , download i-nigma app point with your camera the MP32 box and yo can see that we put a lot of getting started info on MP32 Magic Box :)

Suggestions ;)

Today I did the first test with my new CTX4 V2 (VRBrain 4.5 + external IMU)
Did some simple test in my garden + alt hold, loter and auto land - no probles, and wery stable.

My great VRBrain controller is running code from today (10.10.2013)  (used Eclipse to pull and build the latest code from Emilie, that does an impressive job)

The auto land function works great.

My CTX4 V2 ready for it`s first test :-)

Next is more test, then add GoPro and FPV
