    @Aniruddha On QGC, do the Parameters ever fully load? The reason I am asking is because if the connection to the GCS is not fast enough or strong enough for QGC to fully download the parameters then the other tabs like sensors and actuators in QGC will not appear. Which is why you are having an issue doing the level horizon from QGC. I know that QGC is seeing the video feed meaning you are connected, is the Green bar going across the full length of the fly view bar on QGC?

    @RyanH , from the spin log above, i can only tell that the motor attempts to spin up but re-starts after the open-loop sinusoidal spinup is done and the ESC detects that the motor is not spinning. You should try to clear the debris by spinning the motor by hand first (or use compressed air) and then use the test script to spin for longer periods of time without propeller (changing speeds, etc). You could use a spin step command to automate increasing and decreasing spin speed (without rpm control, since it's not needed): ./voxl-esc-spin-step.py --id 0 --step-delay 2.5 --step-frequency 1 --power 20 --step-amplitude 30 Alex

    @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. Alex

    @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). https://www.modalai.com/pages/contact-us Alex

    @Maxwell-Schaefer Thanks for your reply. Is this step also applicable for the BetaFPV Nano RX? Should this also used ModalAI's firmware repo? Or will this use BetaFPV's? I did look into trying to flash the Nano RX initially, but stopped short of doing it as the physical RX itself did not have a BetaFPV silkscreen on it, so I assumed that it might be using a different firmware from the stock BetaFPV Are you able to advise on the other queries regarding the new wifi adapter board?

    @Leo-Allesch , if you are talking about VSLAM, which stands for Visual Simultaneous Localization and Mapping, then this is a sub-class of SLAM which uses only cameras (and often IMUs, then it is VISLAM). VSLAM and VISLAM usually generate and maintain a sparse map of 3D features (points), which is used for self localization. If you want to be able to detect a target, and you have your 3D pose from VIO (VIO = VISLAM), then you can either triangulate the target location or get it's location from a single frame if you know the size of the target (such as April tag, etc). Then you can transform the coordinate of the tag from the camera frame into your "world" (VIO) coordinates. The depth sensor would allow you to build a more detailed 3D map / point cloud using the 3D pose output from the VIO algorithm (or just using a depth sensor, which may be more complicated). You can also build a dense 3D map using camera only (and IMU), but that typically requires a lot more computation than using a depth sensor. You don't necessarily need a depth sensor for identifying the position of a specific target that is easily detected by a camera. There is a lot of research material you can find on these topics, please look into it deeper and let us know if you have specific questions about using VOXL2 hardware and software. Alex

    @brandon there are likely a number of things going on If the drone sits idle for a period of time, the sensors heat up (accel and baro). When the props start spinning, the temperature drops causing significant drift. If you let the props spin for 10 or 20s cooling off the board, that can help I would guess after 30-60s of flight, the altitude stabilizes. That is the temperature of the sensors stabilizng. The latest SDKs have temperature compensated calibration for IMU and baro. Try calibrating accel and baro and see if that helps. https://docs.modalai.com/calibrate-baro/ https://docs.modalai.com/calibrate-imu/ The GPS on Starling 2 Max has been tricky. We do have a new GPS on the way that looks promising, and hope to make it available in the next 2mo.

    @Moderator Order #7559 And, yes I ordered the configuration without the radio? But I wasn't told that it wouldn't include a GPS module?

    @Nitin-Varma-Vegesna Well, that's why I asked you to do the full SDK installation. If you install the SDK and set it up as we do from the factory then it should be working like when you first got it. If it doesn't then that potentially points to some damage caused by the crash and not some configuration change you have made since then.

    @Muqing-Cao Did you get this working? I was able to get state estimation with the Mid360 through MAVROS, but am now thinking about getting some LiDAR and camera vision fusion for a more robust approach.

    @Nitin-Varma-Vegesna said in Repair: My Starling 2 drone crashed, and a good amount of damage was done. The PCB board was cracked, and the GPS mount was broken, and I was wondering whether I should submit a Repair Merchandise Authorization, and generally how long does the entire process take from submit an RMA to receiving the drone back? I submitted an RMA form, but I would still like to know how long the entire process takes generally please?
