FS Auto Landing > detect uneven terrain?

Posted by Gerhard Laubscher on March 27, 2016 at 12:11am

Hi All,  (pixhawk 3.2.1 Quad X refers)

During a Batt FS Auto Land recently, the quad tipped over on landing. 

  I suspect that it tipped-over since the terrain was uneven.

I saw this youtube vid where it appears that the quad  'detects'

  a possible uneven terrain during its final landing approach, at which time it re-positioned itself.

(watch from minute 17 on the vid timeline)

If I made the correct assumption that the quad in vid can 'detect' an uneven

landing terrrain and attempt to re-position itself,

  I would like to know whether pixhawk FC Auto Landing can do the same?

Thank you for you valuable input.

Gerhard

    I doubt it "detects" anything, more likely noisy data.

    ArduCopter lets you fine-adjust the landing spot while landing, and also handle landing on lopes and icy slopes too where it need to decide to land even when is slides a bit or "fall" into a sloped position after landing.

    Anyway - in difficult terrain, it's always best to land manually - because no current AP will understand if a leg/landing gear catches terrain/grass/rock etc.

      Hi Andre,

      Thank you for your reply.

        It seems that I have to evaluate my rig further.

      Regards,

      Gerhard
