@Roy-Azriel , the description of Starling 2 Max states that it uses VOXL2, as well as lists other major components and options for camera configurations : https://www.modalai.com/products/starling-2-max?variant=48216084087088

Please let us know what Lidar you are considering adding.

@aheyne , please send us a message via contact form. We don't sell this part separately as a product, but will help you with a replacement.

You will need the M0177 flex cable (as the print states on the cable).

@Piyush-Singh , can you please provide more details

how exactly all cameras are connected to VOXL2 mini (including interposers, flexes), etc. A diagram would help a lot which kernel variant are you running on your voxl2 mini (2.0.0 or 2.0.2).

Are all the other cameras working if you disable the TOF sensor in the camera server config?

Alex

@Shantanu-Gupta please check documentation and video for VOXL2:

Hello @RoyAzriel ,

If you are going to be experimenting with adding different sensors (Lidar), then Starling 2 Max is definitely going to offer more flexibility due to the larger size and longer flight time.

You should consider the dimensions of the tunnel and make sure that the drone will easily fit. I have no idea how small the cross section of the tunnel is, but if it is very small (just several times larger than the diameter of the drone), then it would be very difficult to fly due to air circulating in a small space.

What Lidar are you considering adding and what is its weight and communication interface?

The illumination will depend on your specific application, depending on how far you need to see. You should be able to add standard LED lights. if you need to control the LED intensity, you would need to get an LED with built in adjustable LED driver and optionally control it using PWM output feature on the ESC.

Are you going to develop your own mapping and navigation stack for this application?

Hi @Vinny

Thank you for your reply! That's good news:)
We are looking forward to it!

@sjt277 ,

The simplest approach is to use a separate USB-to-serial adapter for each ESC.

You can set up udev rules to map and distinguish the specific usb-to-serial adapters (using their unique serial numbers) to aliases in /dev/, such as /dev/esc0, /dev/esc1, etc.

Then run your testing using different USB devices to access each ESC (i am assuming you are using voxl-esc tools?).

For example, here is some relevant information: https://askubuntu.com/questions/49910/how-to-distinguish-between-identical-usb-to-serial-adapters

Does that help?

Hi @Jon-Brookshire ,

Hello @Myles-Levine and All,

You have been very patient.. Sorry for the delay.

The Step file for the exact configuration you requested has been uploaded to our Assets page:

It should look something like (well, exactly like 🙂 ) the rendering below. Please let me know if you have any issues with the model. It may take a few minutes to load..

@shawn_ricardo A couple of quick points. First of all, PX4 just queries the Linux system time so there's no mechanism to set a separate notion of system time in PX4. If the VOXL 2 is connected to the internet then, yes, it will update the Linux system time with NTP. But VOXL 2 has no battery backed RTC so if it cannot get system time from NTP then it uses the last saved time which is typically the last time there was a connection to an NTP server. Also, in newer versions of our PX4 we get rid of the -t option when starting the logger module so it will not use the system time. Instead it will just create session directories and log files within them in increasing numerical order. So, highest numbered log file in highest numbered session directory is the latest log.

@ndwe Whether you use a VOXL or Jetson as a companion computer shouldn't make any difference unless you want to use the VOXL SDK. The version you run is totally up to you. If our v1.14.0 based version works for you then use it. We do plan to transition to v1.17.x in the near future. I don't think the issues you are seeing are related to something specific in the flight core v2 hardware setup. I would think that if you swapped it out for some other brand you would see the same issue. I would ask on the PX4 forums to see if others have experienced the same issues.

Hi @jon , do you always see the following warning right before the seg fault? (and never see it when there is no seg fault?)

@jon said in voxl-logger seg fault on shutdown:

WARNING, _stop_helper_and_remove_pipe timed out joining read thread

The way one would normally debug this is using gdb, but that would be tricky if you are spawning the logger from another (python) process and don't have a terminal to type in gdb (after crash) to investigate.. You could potentially attach gdb to an already running (spawned) logger.

Hi @qubotics-admin ,

Our understanding is that the voxl2_io driver should present itself as a generic PWM output (up to 8 channels) and you should be able to map any function you need to it. Although we have not explicitly tested every function. Can you please clarify which version of voxl-px4 you are using and elaborate on the "limited options" that you have for selecting the PWM function (what are you expecting to be able to set and what are the options).

Alex

@Sarika-Sharma You can get v1.0.10 here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/libfc-sensor_1.0.10-202602041609_arm64.deb

Thank you very much for your reply Alex. I appreciate the references and support documentation you provided as well.

@Alex-Kushleyev Thanks Alex, very helpful!
