First Flight - SteadiDrone QU4D Brushless Gimbal from SteadiDrone on Vimeo.

As you all know brushless gimbals are the future, and we've just tested our first small BG for our SteadiDrone QU4D, here are some quick clips, much more to come soon. You can check out our facebook pages for more news, photos, videos etc

Regarding ArduCopter and brushless gimbals, would it be possible to impliment a AlexMos type code so that the code/APM can control brushless gimbal motors ??? mmmmmm would be a dream if we could

Yeah Duran! This is where we are all going. 

very stable. 

What motors did you use?

Tilt and rol!  sweet guys... now can I put a standard digital point and shoot camera on it?  Like a Canon S95 or SX230?    I really love the frame.. I think the low side profile of it probably does much better in the wind then some of the other frames that have a much bigger cross profile.

Actually just change your gopro mount to have a common camera screw and just sell the gimbal with a option to add the GoPro Tripod Mount accessory... so then you can run a large variety of cameras not just GoPro.   Then add a slot to allow the user to move the metal bracket up and down where it attaches to the motors.. so that way you can keep the camera lens center to both axis.

No, for two reasons:

1) AlexMos code has been completely closed.  It is no longer Open Source at all, they won't even talk to me about some improvements I was suggesting to them.

2) The Atmega2560 flat out cannot handle any more load.

Maybe on PX4, however.  You'd still need an accessory board of some sort for those FET's, as well as maybe a secondary IMU for the camera tray.

However, I think that this type of integration would be a good idea.  What I'm seeing is that the gimbal will have a hard time stabilizing properly with fast flight.  The horizon goes off-level.  The reason is that when you fly around a bend, it can't distinguish tilt from centripetal acceleration.  Arducopter solves this by looking at the GPS signal and compensating when you fly around a corner.  But AlexMos has no GPS so...

What do you guys make with your Makerbots in the background?  Your folding arm holders?

Dany, using T-Motor 2208

Great info, thanks R_Lefebvre :)

Neill, pre order ?

I think what might make more sense, would be to work with them, or maybe the German open source group, to develop a custom firmware that would integrate nicely with their boards.  If we could feed them GPS info, and remove the stabilization signal from the gimbal control coming from APM, we'd be in good shape.

Hello,
Nice gimbal!
However this just does not solve the issue of jello and camera mount vibrations. I find also very little thinking and innovations and that issue. Ideal would a diy anti vibe camera mount coupled with brushless motors.

@Duran

I was under the impression SBGC was not yet available?

If it is please give me somewhere to buy it...

Or are you using a different IMU?

If so link me that one too, I am in the market... as it where...

Thanks,

Neill
