    • RE: Props spinning affect collision prevention?

      @Moderator Any idea where in the code i would do that? Trying to understand the code but it is a little confusing, a lot of your variables are initialized with pass through values.

    • 4 in 1 ESC caught fire!

      Hello I was just trying to calibrate the 4 in 1 ESC and it caught on fire! Why did this happen? Can you guys replace it? I am so confused.

    • ESC Calibration Error Voxl2

      I'm trying to Calibrate my 4 in 1 ESCs. I run the command listed here https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/calibration.md. At the end, no calibration parameters file is printed, only error. How can i fix this to get the parameters file so i may upload it through the Voxl with this command ./voxl-esc-upload-params.py --params-file ../voxl-esc-params/<params_file>.xml to successfully calibrate the ESCs?

      Thank You

    • Props spinning affect collision prevention?

      How can i black out the frames of the stereo that see the blades so collision prevention will work? How did you guys do it? We have the same exact drone with 10 in props and the stereo sees the props spinning and wont move if collision prevention is enabled.
