Auto tune

Started by Michael. Last reply by Виталик 4 hours ago. 8 Replies

As an engineer and software developer I feel confident we could write software that auto tunes the PIDs in the air or possibly on a fixed jig that holds it in place. Has anyone done any work on this?

Hi all,I recently switched to an external GPS/compass (3DR) and resolved some EKS variance issues I was having. Woohoo. So, I went out today to test a few things (Loiter being one of them). When…Continue

@Gunnar Baardsen  you have the right gimbal, that is the one I was talking about. I use mine with a Naza controller and the servos plug directly into the X channels and doesn't need an auxiliary gyro/IMU. he APM also permits this using any free channels for up to 3 axis control.(see http://copter.ardupilot.com/wiki/camera-mount/

If you decide on the Alware, I suggest that you replace the all plastic servos with ones with metal gears and ball bearing shaft. I am noting some lash from wear appearing. Lately I have been flying a Nikon Coolpix LX810 and I think its weight is wearing out the inexpensive servos that came with the Swing.

@BobKirkpatrick

Is it this 2-axis gimbal you are referring to - http://www.alwarerc.com/shop/swing-2axis-camera-mount-p-67.html

I read from the specs that they recommend the use of a gyro stabilization. I was under the impression that such a stabilizing feature is built-in with the APM 2.5, hence it's not needed with any additional hardware to control this gimbal.

Or am I wrong here?? I have a 3DRobotics quad (under rebuilding to a hexa these days) that I want to equip with this gimbal with a Canon S100 PowerShot camera.

Lovely scenery! Now time for a stabilized gimbal;-) Embedding your video so others can enjoy:

Using my APM 2.5 on a TBS Discovery w/ frsky 2.4 control, Immersion RC 600mw 5.8 and Fatshark Dominators, its taken a few months to get the bugs ironed out and flying (many crashes and about 3 vtx's), but it now flies nicely (though I'm a crappy pilot) thanks to this user group and many other fellow hobbyist. I am getting just over a klm of range with both video and control. Missions work great and loiter is finally stable.. see my quick video in Hawaii (apologies for the jello I have my gopro hardmounted in waterproof case for obvious reasons :)  http://youtu.be/tdV1w0lNKU0 any questions feel free to ask, and again thanks to everyone who helped me :)

Ok, I emailed 3d robotics, they tell me approximately 1 mile, line of site, with FlySky transmitter.

Thanks John

Comment by Tom Gates on December 10, 2013 at 10:49am

Yeah, I understand that, would like to have some idea of range. 1 mile, 2, any idea, even on just line of site.

Comment by John McGrath on December 10, 2013 at 8:43am

@tomgates They are correct your mileage will vary depending on terrain.

FLYSKY TRANSMITTER

Anybody know what approximate range of the FlySky transmitter and receiver is with 3d robotics quad?

3d Robotics tells me the telemetry on board is good approximately a mile, more or less, given the terrain etc.

Awesome new feature in ArduCopter 3.1. Thanks for the tutorial Randy!

Hey everyone.  Just got in a second quad power distribution board in today and want to turn my quad into quad-8 or Octoquad.

I purchsed a second pdb thinking I can use it to power the additional motors.  As I look at the quad and octoquad motors setup I see that the quad motors 1,2 are diagnal for the quad but are clockwise on the Octoquad top motors and 5 trhu 8 for the bottom motors clockwise.

Long story short does anybody have advice on using 2 quad PDB's to make an Octoquad?
