AirbotServices Pixhawk/APM:plane 3.3 XUAV Talon training session

Posted on July 10, 2015 at 1:57pm 9 Comments

Hi,

If you ever wondered what professional drone designers/makers are doing behind the scenes, well we're not only building UAVs for customers but we also have to train them from A to Z (and often we have to train ourselves too:).

To show you how this is made, enjoy this little video of this morning's training session (for agronomy…

Didn't want to say this in the crowd.  But I think mass distribution has a bearing on the PIDs as does distance from the respective axis.

Example:  Say there is a rectangular cubic battery pointing fore and aft at CG on a symmetric quad copter.  Say the rotors are 20 cm from their axis and the battery is 10cm x 2 cm.

o The torque factor exerted in pitch over the battery would be 20/(10/4) = 8 to 1

o The torque factor exerted in roll over the battery would be 20/(2/4) = 40 to 1

If you have two steel wheels of the same mass, the larger one will be more difficult to get rolling (there is a larger change in momentum).

So it is 5x easier to roll than pitch.  I think that should be accounted for in the PIDs?  But maybe I'm wrong.

Of course this is an extreme example where everything else weighs nothing, so the differences in ratios are never that high.  But it is common I think for the factors to be up to 1.5X.

Your thoughts?

At 1:42pm on November 8, 2013, Tyler McGahee said…

Yeah, the PIDs are definitely affected by the "mass distribution" (moment of inertia), as well as by the motors and propellers and ESCs and the control algorithm and on and on. I don't think it hurts to list the PIDs though. Could save some time when starting from scratch on a similar or identical rig.

Hello,

A curiosity ... as I turn apm 2.5 and esc with 2 separate batteries.

Battery 1: APM 2.5 and FPV
Battery 2 Engines - BECS (servos)

Unrecognized?

Thank you!

Ardupilot on PX4 + IO won't arm motors.

Hi I have the same problem Mystery 30A ESC's ...

You Might explain "load up the firmware ArduCopter" Bootload firmware?

System works without problem, arm and disarm perfectly.

Safety Switch OK.

Calibration OK, ENGINES TURN.

Connect and disconnect battery and ESC sounds uncalibrated, not save settings.

Hi,

You know it could be?

Another question.

You know how I connect to OSD Remzibi px4 as if telemetry data and to see video on my monitor?

We appreciate evidence.

Thanks for you time.

You are responsible to give answers of diydrones community? curiosity!

Thanks.

4 motor mounts and 4 tube plugs, cut, lightly sanded, ready to ship, and after you clean, ready to adhere.

Where do you want me to send them?
