With our partners AES. This is a great way to really quantify performance!

Can you share the results from your testing?  Such as error, lead, lag etc?

Very good delta robot use!  Just need a coordinate system mounted on the wall and the camera pointed at it and a closed loop running to the camera to measure the error in tilt to create be able to graph the results.  might as well put laser level on it and shoot it over a long distance to visually show the error.  My two cents.  Makes me want to find the time to finish my delta

Cool, with a repeatable  routine for the "wobbler" each gimbal can be tested against a known set of parameters.

Objective results every time.

does this mean that the tarot gimbal came out best if it's what 3dr chose?

Sure nice , but don't enought you don't have important variable as : high frequency vibration ,  high centripetal and centrifugal acceleration , HIT and wind  simulation .  

The better way for doing this kind of simulation is to use an ABB robot

Our new gimbal and imu  technology will be tested with this kind of robot.

Chris: Make a gimbal for 250 quads and ill be impressed and buy it, and so will many others.

There no current brushless gimbals in that size on the market, but you already knew that!

Ben, yes, there is a coordinate system on the other wall and machine vision algorithms used to collect all the performance data. We didn't want to show all our secrets!

Is this test rig available commercially?
Comment by MC on September 18, 2014 at 8:57am

What are the model of those high speed linear actuators?

Are they electric or pneumatic actuators?

Nice Navoni, you are right, high frequency vibration ,  high centripetal and centrifugal acceleration are the most important point in a good gimbal controller.
