Have you looked at voxl-tag-detector?

Thanks Chad. We did the calibration again with a better calibration target, and this fixed the problem.

@alarm_hq said in How to: Seeker ESC calibration:

And if I've already made the "mistake" of reflashing px4 firmware, is the closed loop RPM control affected?

The ModalAI ESCs used on Seeker have their own firmware and settings stored on the ESC itself, independent from PX4 so your ESC is fine after changing PX4 firmware.

Hey @alarm_hq! The props for the Seeker development drone can be found here.

Thanks, so what is the emulator for exactly? emulating native compilation? I am unclear of the emulator use case if it is not intended to emulate the voxl platform for application testing. Let me know, cheers!

Hello @alarm_hq!
Please see the updated readme on voxl-mapper's dev branch for an overview guide of this package. As for the timestamp too new error, this error typically arises when there is a VIO blowup, and one way to prevent this is by ensuring that the tracking camera is correctly calibrated pre-flight. Also, please see the overview guide for instructions on viewing, as RVIZ is no longer utilized!

Alright! Thanks for the update, I'll likely use this post to get some updates to our docs, appreciate it!

I found the QGC
EKF2_AID_MASK parameter settings above (configuring to 280: Vision position fusion, vision yaw fusion, vision velocity fusion) to allow the seeker to enter position and off-board modes.

Prior to configuring, QGC was receiving VIO but was still unable to enter position mode as referenced here

To make the forum search engine happy: seeker position mode rejected

@Nirge You should use voxl-wifi for wlan0.

@Shlok-Agarwal I assume you've taken a look at this page in our docs: https://docs.modalai.com/unbrick-voxl/

If not, give that a read through and it'll give you a bunch of good info.

Were you able to ADB into the VOXL before you started the flashing process?

Thank you.

@omer-b thanks!! Added:

It appears this happens when the sensors are not calibrated on the drone. voxl-vision-px4 picks up on sensor inconsistency and restarts PX4.

So, calibrated the sensors. Looks better

are you sure that this is the Vibration damper that you are using? cause your 3D cad model calls for a damper with different dimensions:

please advise which damper are you using in your Voxl flight deck.

These are the dampeners we are using on VOXL Flight

The dampening may needed to be tuned for your flight platform though, and can definitely be different depending on flight dynamics. We have had a lot of success sticking a piece of foam between the plate and the frame.

@Steve-Arias,

Once you have voxl-portal started either via the command line or as a service, you can access the webserver on a device within the same network just by navigating to your voxl's IP address.
