Landing Sensor on PX4 Autonomy Developer Kit

frafrat

Hello,

I just bought a PX4 Autonomy Developer Kit since I noticed from this that the VL53L1X sensor is used as a landing sensor. Can you please explain how this sensor is connected to the VOXL and how I can set the PX4 to use it correctly?

Thanks a lot for your time

@frafrat It isn't really supported yet. It's there as a future enhancement.

@Eric-Katzfey I see! But is the sensor somewhere in the PX4 Autonomy Development Kit drone or it is not there at all?

Thanks

Hi. The sensor is integrated into the VOXL SDK and raw data can be viewed through ADB or SSH with the voxl-inspect-rangefinders command line tool. All PX4 Autonomy Dev kids have this sensor. That data is sent from qrb5165-rangefinder-server to PX4 via voxl-mavlink-server. To enable in PX4 set the PX4 EKF2_RNG_CTRL param to 1. You will likely need to fiddle with PX4's other rangefinder params to achieve the behavior you want.

Best,
James
