Dear Friends,
VR Lab is happy to present our last updates in the project in last week we doing a great upgrades :
The entry level mechanical GoPro Fiber Carbon Gimbal is ready only 158 gr with motors, in the video you can see the first test, It's very simple to balance the camera to obtain better result.
The VR Gimbal is ready for developer we put online the opensource repository , in the next days will be update with recent workspace : library and code the code is compatible wit VR Universal IDE .
https://code.google.com/p/vrgimbal/
Today we finish to implement the first version of code that manage motors on pitch , roll and yaw . In the first test we are using only P not yet ID for improve corretion but the result is yet very good , in the nexts days put online new video:)
Now is possible to setting the parameter with a serial port interface : sensor calibration , PID , on and off of motors , power for control the motors , step / degree ecc ecc . We start to develop a console for end user. We would use mavlink for interconnect the Gimbal to Console application ... in our test we are yet using also 3DR Radio and it work fine !

Dear Friends,
some news about status of hardware : http://www.virtualrobotix.com/group/vr-gimbal-user-group/forum/topi...
Hi James ,
we are using same approach also in our ahrs in Arducopter project ...
Hi Chester,
sorry the store is not yet available is coming soon... check here for more info :
http://www.virtualrobotix.com/profiles/blogs/virtual-robotix-italia...
will be in 1 or 2 week ... for more info about the products write an email to info@virtualrobotix.com
I check the link was a problem in landing page of store for mantainance reason we are updating it.
James, what's an INS algorithm?
Very NICE!!!! I like it. Is there any way to purchase it? I tried to folow store link on http://www.virtualrobotix.com/ but look like some tech problems on site it shows error: jtablesession::Store Failed
DB function failed with error number 145

Roberto, good work. I'm looking forward to trying your system. The AlexMos is getting a bit annoying. They are closed source, and aren't doing a good job keeping up with documentation or solving problems, and there's nothing you can do but complain because it's closed source.
I also think the gimbal controller will benefit from a closer relationship with the flight controller.
Hi James i like a lot going with sailboat ;)
This was some years ago before to have 3 kids ;) I'll check your doscs ... i hope in the next days to have some times to improve the control routines ...
The idea to use gyro to create a phase lag/lead in the output i yet consider during my first test ... but i think that could be improve a lot our code in the next weeks .

Hi James,
you are doing a great work :) I follow you on TauLab project ... Stefan working on Tau Lab code for VR Brain , Emile on Arducopter 32 rev 2.9,x and 3.0.x and I start to work on VR Gimbal ;)
About sparky you are sharing your code for brushless gimbal ? Where is available ?
Our code start from Arducopter Lib not from TauLab .... could be nice evaluate different solution or sinergy approach ;)

Very interesting. I'll probably have to get one to test.
I have one suggestion. All the "cheap" direct drive controllers available at the moment are 2 axis only. If you included the third pan axis, you would have a guaranteed winner.
