This video is doing by our VRGimbal user VR Gimbal with Sony 3D HXRNX3D1U ( 720 gr)  in handeld mode

This is a video using complete VRGimbal with Panasonic GH2

..and this is another video of the same copter (in HD)



Dear Friends,

These are specification of our : VR Gimbal :

Micro Controller is STM32F1 at 72 mhz.

3 Axis Brushless Direct Drive gimbal :

  • Roll    (MOT1)
  • Pitch  (MOT2)
  • Yaw    (MOT3)

For each channel we have 3 high power pwm 5 Amp output .

I2C IMU that support 3 axis . It  is on camera module , so we can know exactly the position of camera and control in realtime the 3 Brushless motors. MPU6050 (6 DOF) + HMC5883 (3 DOF)

1 USB port.

1 Serial port that support mavlink protocol.

1 Power module that support until 3S battery.

4 Radio RC Input for :

  • Control ROLL Setup.
  • Control Pitch Setup.
  • Control YAW Setup.
  • IR control repeater.

4 Analog Input 0-3.3v

1 IR Out , so is pssible to control a remote camera by its ir receiver.

On new revision 2.0 we add :

  • customizable push buton.
  • support for motors ampere  monitor for each motors.
  • Very intuitive Firmware update tools.
  • Simple and powerfull VR Gui for VR Gimbal configuration.
  • Serial driver on USB port.
  • A complete and updated wiki repository with media gallery with last video from our user.


In this video is possible see the utility available for measure the current used by different kind of motors. This feature is very usefull for evaluate the specification of motors.


Is available a new tools for firmware update you can found more detail here  :

We release a Major release 1.0.9 we add a lot of new functionality and full support of pan stabilization with 1 IMU sensor  or two sensor .

rev 1.0.9

  • Experimental Stabilize mode on Yaw (good with small pitch values)
  • Experimental Follow mode on Yaw (need motor steps calibration and PID reconfiguration)
  • Experimental support for second IMU for precise Yaw measurement (contact us for more info)
  • Added support for analog/digital input (like joysticks and buttons) to be used in alternative to RC:
    • configure channel 100 to 105 to use analog input 1 to 6;
    • use the “JYC” serial command and follow the instructions to calibrate the inputs.

rev 1.0.5

  • Completed PID mode on Roll and Pitch, with support of RC commands.
  • Manual (RC) mode (to be used on Yaw for now) working but requires improvement.
  • USB serial support (see vers. 1.04)

more info is available here :

The firmware is opensource the repo is available here :

So if you want to join in development you are welcome .


This is a screenshot of VR Gimbal Gui developed using .net technology, so could be work also using mono on mac and linux , test on that platform is welcome ,you can connect directly by usb to VR Gimbal or by radio link as 3dr module , blueetooth or other ttl wireles adapter :

We Upgrade also the VRGui with new functionality , slider full support of Pan axis and Full Frame.


With VRGimbal is possible to control this kind of gimbal ;

Handheld and Air Drone Gimbal 2-3axis Entry level gopro gimbal.

Handheld and Air Drone Gimbal 2-3axis Heavy dslr gimbal.


This is an example of video doing by our user of VRGimbal on heavy dslr gimbal :

This is official thread in virtualrobotix community is here join us for have more info and support :

For reserve and pre order your VR Gimbal 2.0 board send a mail here :

Is possible to buy our board on our new ecommerce store here :

or if you prefer you can contact us at :

We can also support our user in custom development  on oem - odm gimbal hardware or firmware contact us for more detail.

Dear friends,

after hard work on firmware doing by Arducopter and Virtualrobotix Dev Team , we are happy to present the result of this incredible test ... this is only first test VRBrain vs DJI Wookong .

The firmware is ARducopter32 rev 3.0.3 , this revision of firmware use AP_HAL library to interface the Arducopter application . The firmware is mantain by Arducopter devteam , the last improvment doing by Leonard that solve some glitch in loiter , and gps override mode.

The result of work doing by Randy and the other member of the team is incredible , we fly the quad in gps mode and it fly as robot ... as Dji Wookong .

This is a video doing during VR Lab test of new VR Lifter frame.

But if you like fly in stabilize mode you can enjoy you a lot. :) I prefer a lot fly my quad in stabilize and acro mode it's nice.

The power of VRBrain with its  STM32F4 microcontroller  have 164 mhz of clock with internal dsp have a more  power of DJI Wookong cpu that use SAM3X micro processor at only 96 mhz and don't have dsp processor for hardware math processing.

Now the new revision of VRBrain 4.5 can support also an external IMU so we can solve the vibration problem with mechanical patch.


Whe have a great new wiki page for support the user :

A new tools for update the firmware is available and will be release in the next days , so you can choose your code download local and program the board without problem.

We are very happy of VRBrain performances :)


Thanks to Marco Robustini for his great video :)

VR Brain 4.5 + VR IMU GOLD is coming




This is the first picture of VR BRAIN 4.5 + VR IMU GOLD.

Thi new imu expand the number of imu available for VRBrain .

With this addon is possible to have two active imu controlled by VR Brain.

On VR IMU Gold there are 3ACC 3GYRO 3 MAGN and a EEPROM for store temperature drift correction table.

With this kind of option we intend to improve a lot the quality of VRBrain for GOLD (Prosumer version ) and VRBrain PRO.

Now we are in development stages :) This is a good hack for your VR Brain 4.5 ;)

B.O.D is a VR Copter with this configuration :

  • VR Brain 4.5 with Arducopter 32 rev 3.1rc3 on board
  • 1 3DR Ublox GPS
  • Use 4 VR ESC prototype 30A with MultiWii ESC .
  • 4 T-Motors
  • 12 APC Inch Propeller.
  • 1 Lipo 5.800 Zippy compact.
  • 1 3DR Telemetry Module.
  • GoPro Hero 3 Black on board


With this configuration i doin 3 hours of fly test , normally the drone fly for 20 minutes with this configuration this is a good result for us.

With Arducopter32 rev v3.1rc3 our drone fly very well i testing all functionality :

Stable mode.

Loiter - Atti GPS mode with ovverride of position.

Return to landing point work fine .

Waypoint navigation work fine , too 

I found only a problem on hard stop when reach waypoint and RTL , some suggestion about the reconfigure parameters for have smooth stop instead of hard ?

Do you like our first RTF drone ?
