Maximum number of Lidar for Object Avoidance

Hi all,

I'm setting up my PX4-based quad with ST VL53L0X Lidar sensors (I currently have three) and I noticed that line #24 of the current Rangefinder library (here: has the maximum number of sensors set to 10 (ten). Am I understanding this correctly? And has anyone ever tried to setup this many rangefinders (or anything close) with any measure of success?

Any input/advice will be greatly appreciated.

    Looking at the update_sector_data function you can see that the angle is specified, since the same fields can be defined in your sensor setup (as far as I remember) then your setup could work. If not you should be able to patch it or in worst case create a driver similar to the TeraRanger one.

    Another thing to note is the potential cross-talk between sensors, try to check it as early as possible to avoid being disappointed!
