Hello ModalAI Team,

I have a Starling 2 drone:

system-image: 1.8.02-M0054-14.1a-perf
kernel: #1 SMP PREEMPT Mon Mar 24 22:31:58 UTC 2025 4.19.125
hw platform: M0054
mach.var: 1.0.1
SKU: MRB-D0014-4-V1-C27-T8-M22-X0
voxl-suite: 1.4.5

Services:

When using the navigation of the Mapper, after plotting a location like this short route with no obstacles:

The drone flies up into the ceiling. The position mode works well though it can drift upwards some. The drone can run the figure 8 without any issue. So far, I am not sure what the issue with the navigation once the Mapper create the route. It am afraid the drone with break itself or something else in the room. I can attempt to send videos of the fly if they would be helpful.

@tom It was a PX 4 Dev Kit. But, thanks for the help. I was able to get the cameras calibrated. I will testing the manual and hold position fly-modes before trying any cv-based flight/navigation. I'll start a new thread for any future questions.

@tom Thanks. I ran the check calibration:

voxl-check-calibration
Calibration File Status:

I assume I should calibrate the tracking cameras still.

@tom Thanks for the help. I followed your instructions and rebooted. When I inspect the services, I get the output:

FAILED TO EXECUTE: voxl-configure-cameras 27

The serial number is M23000003CZ.

The drone was originally a PX4 Dev Kit. But, it has been upgraded with the parts for a Starling 2 with 3 tracking sensors. Support helped provide the necessary parts and brackets. The main addition is the:

MDK-M0187-1-01 Dev Kit, VOXL 2 Lepton Plus TOF V2 Adapter Board & MCBL-00105-2

The Lepton adapter board isn't connect as there currently isn't a sensor attached. I have attached pictures of the drone fully assembled.

@tom

I don't really get any options when I try the configure camera command:

voxl2:~$ voxl-calibrate-camera tracking -f
Waiting for valid pipe...

It just says waiting for valid pipe.

I will double check the stickers and provide the serial number once I find it.

Hello,

I am trying to calibrate the tracking cameras on my Starling 2. After running voxl-configure-mpa it seems that the calibration files for the tracking cameras is missing.

Here is the current configuration:

system-image: 1.8.02-M0054-14.1a-perf
kernel: #1 SMP PREEMPT Mon Nov 11 22:08:01 UTC 2024 4.19.125
hw platform: M0054
mach.var: 1.0.0
SKU: MRB-D0014-4-V1-C27-T8-M22-X0
voxl-suite: 1.4.5

It has the three tracking cameras, hi-res camera, and ToF sensor.

I follow the configuration wizard (voxl-configure-sku --wizard) with these options:
camera configuration: 27
transmitter options: 8
lepton: 2 / no
modem hardware: 22

I then ran voxl-configure-mpa after the configuration. I got the following output:

     FAILED TO EXECUTE the following steps:

            PLEASE POWER CYCLE YOUR VOXL

Following the documentation on calibration, I tried to calibrate the cameras. I tried the following commands:
voxl-calibrate-camera "tracking front" -f
voxl-calibrate-camera tracking -f
voxl-calibrate-camera "tracking down" -f

I opened the VOXL portal and was not able to see the camera feed for the calibration. I included a screen shot of the camera_calibrator_overlay section of the VOXL portal.

Thanks @tom. Is there any other avenue I can try? I've sent a couple of email with no response.

Thanks @tom. Is there another email address I can reach out to? The mail server has returned the same error twice trying to deliver and email saying that, that email address does not exist or that won't accept a message.

5.1.0 - Unknown address error 550-"5.1.1 The email account that you tried to reach does not exist."

Do I need to fill out a support form first?

Thank you, @tom! I assume this doesn't come with a bracket to attach the camera/sensor to the drone. Is that correct? Is the bracket available for purchase? I don't see it list in the accessories.

Hello ModalAI Team,

Is it possible to buy the components necessary to bring a PX4 Developer Kit drone up to the capabilities of the Starling 2? We would like to have access to the 3D Mapping and navigation features of the Starling 2.
