I've searched ArduPilot and RCG for information on LIDAR, range finders, MaxBotix etc., and am curious if anyone is using any of the ~$40 MaxBotix sensors for enabling accurate landing flares. From what I can see online, I2C seems better than analog, and MB1202: I2CXL-MaxSonar-EZ0 seems like the best device for basic landing detection. My ideal application here is landing 3+ meter gliders at slow near-stall speed, for either a smooth belly landing, or possibly a hand catch. If landing behavior was linear, predictable, stable, etc, I could see going for the hand catch at the moment of a flare ~1 meter AGL. The MaxBotix literature talks about noise isolation, both electrical and acoustic. I was envisioning embedding the sensor in the wing, away from EMI, motor noise, etc. Welcome any thoughts on this.
I've researched the more expensive range finders, and am not too interested in spending hundreds of USD on this enhancement to ArduPlane landings.
