It was a massive lift on my end. Many changes as you can see from the pull request. Years of development

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

resolved

My fault. Found a small tear in the ribbon for the stereo cameras

RESOLVED

I think these documentation pages are the same.

Not huge deal, but thought I would post ticket to track

Docker container non-deterministic fail

I am trying to start a container with the following command:
docker run --rm -it --net=host cal_compass:latest

Sometimes it starts right up. Other times it gives me this error: Cannot start container 05621665b072b85b6419f904c0ffb511a1ad07a32c1ca675820aaadbefa4a316: [8] System error: write /sys/fs/cgroup/cpuset/system.slice/cpuset.cpus: invalid argument"

Any ideas what could be wrong? Thank you for any insights

@Caleb-Rievley are you loading firmware 1.12 and 1.13 on the VOXL Flight?

ModalAI comes out with their own versions of PX4. Let me dig up that URL:

https://docs.modalai.com/flight-core-firmware/

Hello,

We have a UAV we would like to fly indoors and outdoors without landing during that transition.
I know that there is support for EKF2 GPS/VIO "fusion" using 329 as the EKF2_AID_MASK in PX4
Link to tutorial

We were thinking of manually changing the EKF2 bitmask when we fly indoors or outdoors.

My question is, are there any software/features available that would more easily support switching from GPS to VIO? Want to make sure I am not redoing work before I start.

Thank you

So it turns out that the post-running script for docker service relies on the image "hello-world:latest"

I had uninstalled that image to save space.

Redownloading image and trying again

@modaltb This worked for me. Removing the USBC cable, booting up, and then plugging in.

Wanted to update this by saying I experienced same issue, but I resolved this by disconnecting tracking camera that had been installed upside down. So, if anyone is reading this in the future....try disconnecting your cameras attached to the board

Was curious if voxl-fan was taken out of SDK 1.5

@wilkinsaf

1. Yes this is definitely possible
2. You would need to modify flow-server and possibly feature-tracker to ensure this is pointed at the right pipe
3. Might also need a bit of calibration here and there
4. Have not tested having multiple versions of flow-server, but should be possible.
5. Would need to ensure this works with a downard facing tof for accurate height estimate

To get a rough draft of this working, would take ~2 days

Hello,

Had a general question about flow server

1. It appears that the flow server is optimized for the lepton, but was curious what the lift would be to get it working with another camera. I see I can change the pipeline:

Wondering if there are any more "gotchas" besides changing the camera pipe and resolution

2. multi-flow: I understand that voxl-flow-server only allows for one camera stream at a time. Is there anything preventing us from spinning up multiple instances of it in order to have multiple flows running?

Thank you!

@Rocio-Lopez Not sure.

You would have to ask Gremsy about that possibly

From James (the guy who set the parameter)

feel free to increase it. Starling 2 Max has a very high power to weight ratio so I artificially calmed it down by limiting throttle

Hello,

I am looking into increasing the max thrust on starling 2 max. Currently it is set to 60%. Wanted to increase it to 100%.
I IMAGINE that it is set to 60% to ensure that the motors do not overdraw from the LION batteries, but wanted to ensure that was the case.

Something is in the works

Hello,

So, we are able to do the voxl 2 mini to hadron. Which is awesome!

However, it would be even cooler to have a converter off of the gremsy hadron gimbal in order to add the voxl2 mini's power onto a smaller camera/gimbal setup.

Here is a video that better describes what I mean

@wilkinsaf

A color AR0144 exists, but there is no current integration readily available

Hello,

We were curious if there is a way to integrate a color tracking camera (or if there is even a color tracking camera that exists).
The reason being, is that for extremely small UAVs it would be ideal to have 1 tracking camera that is

1. being used for VIO
2. being used as the FPV cam
3. Being used to collect data of surroundings

But, to be used as an FPV cam and data collection the camera would have to be color.

Thank you!
