@Eric-Katzfey Is there an existing service/configuration for collision avoidance on these platforms or do we have to implement our own using the TOF sensor data?

We love incorporating merge requests if you do end up with something useful!

I've made a quick fix here for anyone looking for it, ill try to make a merge request/real fix for it soon

@Eric-Katzfey I'm having the same issue on the VOXL Starling, the /etc/modalai/voxl-dfs-server.conf file is set to use the rear and front stereo intrinsics.yml and extrinstics.yml which don't exist due to what you just mentioned. Is there a specific setup/files we should set the voxl-dfs-server.conf to use ?

Re: Fixed frame pose MPA to ROS

Similar to the various above threads, I am trying to figure out if there already exists some way of getting the detected April tag's offset relative the the MAV's local frame (for reference I'm using the frame that /mavros/local_position/pose provides). I'm unsure of how I can achieve this aside from manually piping and shifting through the data outputted by the voxl-inspect-tags command and converting into a ROS Pose. Do let me know if there already exists a method for accomplishing this or if there would be an easier way to retrieve this offset into a ROS pose.

For reference I am using a Starling with VOXL2 and system image: 1.7.6

My goal is to visualize the position of the drone relative to the detected April tag for accurate position targeting.

@Eric-Katzfey Is there a reliable link to a working version we can purchase or exchange it with? Thanks!

Hi, I've been having issues setting up the HITL simulator using this cable connected to the VOXL2 J18 port on the Starling: https://www.modalai.com/collections/accessories/products/mcbl-00010
and I've been following this tutorial: https://docs.modalai.com/voxl2-PX4-hitl/

When I connect this cable to the host-PC running Ubuntu 20.04 there is no USB-serial connection detected or made other than the existing USB-C port and it is not found in /dev/ttyUSB# and dmesg -w does not show any connection being made. I am unsure if this is a cable issue (I've tried numerous mini-usb cables) or a problem with the way Linux handles the connection as this tutorial video has a similar setup: https://youtu.be/ysvpJdXFWaM?si=1ltYazXT03agZOAl

Any help is appreciated, thanks!
