Multipilot 32 + VR IMU 1.0 First Times in The Sky was a windy Day early revision of arducopter 2.0 onboard :)



In this video you can see the first flight doing with Virtual Robotix IMU , in the test i only check the sensor board , Gyro and Accelerometer , in the next test i check navy and input output functionality.

 

Today was a windy day , after solve with Randy a problem on the YAW control .. i doing the preflight check , all seem to work fine and so decide to going in the sky.

 

I'm using the same PID used with oilpan , there're not significant difference ... In the next day i try to use 300 °/s gyro ADXL 610 to check the difference respect of Inversense.

I think that the new board will be available in the next week for the people that are interest to evaluate it .

This board is an upgrade of original Oilpan board , it's compatibile at 80 % with the original dirver , my idea was to improve it and put my experience on gps and uav on it. I add some feature as subsystem power control , gps battery backup , improve temperature compensation on gyro , add gyro that i used on MP8 the same of mikrokopter.

In these days i doing small upgrade to adc driver and to the code .. i think that tomorrow i can doing a first flight for test it , On Artificial horizon yet is ok .. i need to upgrade the driver of compass .. and right projection.

My idea is to have only one board put on MP32 or APM without , cable to or header to connect the device togheter .. if you need can disconnect the sensor imu and put it where you want and can connect it by cable to navy board.

Do you like VR IMU ? This is tech info :

 

Preliminary VR IMU 1.0 (Dominate the Sky) Technical specification:

 

Imu Sensor :

  • 1 Gyro Z : Inversense ISZ500 500 °/s resolution 1 axis.
  • 1 Gyro XY : Inversense IDG500 500 °/s resolution 2 axis.
  • 3 Gyro ADXL 610 300°/s resolution same used on Mikrokopter (option).
  • 1 ACC ADXL 335 3G resolution.
  • 1 Magnetometer 3 Axis HMC5883 compass functionality.
  • 1 ADC 12 BIT ADS7844 8 channel. 2 channel used for temp compensation.
  • 1 FET for ON / OFF subsystems.
  • Possible to disconnect the Imu sensor and connect to Navi by a cable.

Navi Sensor:

  • Barometer : BMP085
  • GPS Mediatek all in one (Default) protocol MTK16 10 Hz update integrated Aerial.
  • Locosys GPS (optional).
  • UBlox GPS (optional).
  • GPS Battery Backup.
  • 1 FET for ON / OFF subsystems.

Input Output:

  • 6 12 Bit analog input available for Board Setup or for interconnect accessories.
  • 4 Digital Output
  • 3 Status Led available
  • Differential pressure sensor for air speed. ( possible to disconnect from in-out board and connect it by cable)

my intention is to build smaller copters.

now we get a big shield.

i could use one ;-)

what is the price?

Cool! Cannot wait to get one.

BTW Roberto, for the MP32, I noticed that when I used the USB power the board, the Serial 3 output works fine, but when I used the BEC to power MP32, there is nothing on Serial 3.... what do you think for this?

Thanks,

Stefan
