Example of VR Drone configuration : Tiger Shark in X8 configuration + VRBrain 4.5 + VR Gimbal + VR Easyshot the camera is an Nex6
An onboard video from Tigershark see the quality of loiter in azimutal video :) The Flight board is a VRBrain with APM Copter revision 3.1.13

After one year of development Gimbal VR has become a stable product.
The latest revision of firmware, we have implemented several functions to make more 'precise and reliable control of brushless gimbal.

In addition to improved hardware and firmware have also worked a lot on the mechanics of these two gimbal one dedicated to compact cameras and another for professional cameras.

The VRGimbal is the only 3-axis opensource gimbal board. Last update is available here.

If you want help us in development join us :)
The goal of the project is complete integration between the autopilot that use APM code Copter, Plane and Rover to develop complex functions such as object tracking.
It 'available on the wiki APM is an example of how to integrate VRGimbal with cards based on how VRBrain APM, APM 2.6 or Pixhawke.
Randy join in test and developing of VRGimbal and add this page to APM WIKI :

since it's said that for VRGimbal both the hardware and software is open source, may I ask, where are the hardware sources? (couldn't find them on the wordpress blog nor the code repository)
Thx
BTW: good work!
@Randy @All ,
sure could be nice add new developer to our project to improve it with a lot of great functionality .
If some one is interest to join can connect me by skype my nick is virtualrobotix

@Adam,
it's normal when the battery is disconnected the gimbal is not perfectly stabilized ... the camera had cover :) When plug the battery the gimbal after 4-5 second recover right position :)
Yes, I recently updated the Cameras and Gimbals wiki pages and included a new page describing how to set-up the VRGimbal.
As far as I know there are only two open source (hardware & software) gimbals out there. There's Martinez and then there's Roberto's VRGimbal. OlliW has recently open sourced the hardware side of his gimbal but not the software side.
I hope that if other people are interested in contributing to developing a good 3-axis open source that gimbal they consider working with Roberto instead of trying to develop something from scratch. Making a good brushless gimbal at the level that can compete with the closed source solutions (like the tarot gimbal, zenmuse, etc) is really hard so best we work together!
Looks like you might need taller gear with that lens touching the ground.
Thank you Dave , we work hard to obtain this result , but now the VR Gimbal work fine and we understand some Tips and Tricks for doing good PID and for Mechanical Setup.
So on this kind of application we have a lot of problem to solve :
1) The Vibration .... as you see in the video now nothing vibration ... this is solved by a mechanical solution :)
2) Mechanical balance of camera ... is not so simple but we understand the step for doing a good mechanical setup.
3) The Fast correction using only giro and less accelerometer ... we working a lot on algorithm and solve some problem that found in first release of code.
4) The control of any kind of motors : we introduce some algorithms for limit the control of the PID when you are near to the end of sin rotation ... so is possible to control also motor until 24 - 32 .
5) The control of 3Th axes , is not simple ... need a good mechanical setup and good motor in our design implement double imu for have less transformation error.
We are not yet finish the code but understand how can continue the development of VR Gimbal ... now the next step will be implement Mavlink protocol , and CAN bus ,too on VRGimbal for a good integration with APM technology.
