@Rishi-gnanasegar There is not going to be an easy way to install after we have built the drone. It is not meant to be plug and play as the plastics are different based on which sensors have been ordered when the drone is ordered.

@SystemBrute . The problem has been solved.

@Cliff-Wong Hi there. Thank you for answering my questions. We’re still using the same voxl-open-vins-server.conf settings with "en_vio_always_on": false and "en_auto_reset": true. I also updated the system to SDK 1.5.0 as suggested, but unfortunately, it didn’t seem to resolve the issue.

To further investigate, I tested VIO performance by holding the drone in my hand and moving it manually while observing the trajectories in the VIO visualization. I noticed two distinct trajectories being displayed: QVIO and OV. Sometimes the OV trajectory appears more accurate when I move the drone in a “plus” pattern, and sometimes the QVIO trajectory is more accurate, but most of the time it tends to drift significantly, and sometimes QVIO doesn't move at all.

I have two questions:

1-) What is the difference between QVIO and OV, and which one is actually used during flight for position estimation?

2-) What could be causing QVIO to fail to track properly, while OV performs well? (or the other way around)

Also, I'm not getting any 'manual control lost' errors in QGC, and I'm able to control the drone perfectly fine. However, it doesn't respond to any control inputs on rare occasions, where the drone can't hold its position and continues to ascend when I use VIO in 'Position Hold' mode.

@jimbow77 , regarding #4, there are four batteries (two sets).

#3 - we don't have an option to install FLIR Lepton, but you can purchase it separately (from another vendor) and install it. The adapter is present in Starling 2 Max, so you would just need to install the Lepton sensor into the socket.

Were you able to solve this issue and unbrick the device? Can you explain how?

@Jakub-Tvrz said in Starling 2 Max for indoor:

We haven't bought anything yet, but we are deciding what will be the best for our warehouse inventory application. Of course, we considered the ToF option. But you still say: "however, it is not... great" - does that mean that Starling 2 is better for our application? Or does Dual vs Triple camera for Visual Inertial Odometry also have an impact?

Depends fully on your use case. I will say that PX4's instance of obstacle avoidance is not fantastic, but it is better than nothing. In my opinion I would go w/ the model that has all the bells and whistles in case you need the hardware and decide to develop your own collision avoidance or somethign of that nature.

@Nitin-Varma-Vegesna If you are just flying in manual or altitude hold modes then those shouldn't be an issue.

@Eric-Katzfey I updated to SDK 1.6.0, which fixed the power display issue. I was still getting no valid local position preflight fail, but after I ran apt update && apt upgrade, things seemed to work.
