First Crash - looking for input

Posted by Richard Jacobs on February 16, 2015 at 4:08pm

Well, I think it may be a right of passage. I was flying a very simple mission from Droid Planner today when everything went amuck.

  1. Sent DroidPlannner mission plan to Iris+ (via Nexus7).
  2. Lifted in AUTO, Way-point should have sent it southeast. It headed that direction initially,
  3. but then abruptly headed for trees,
  4. I think I flipped to STD Mode, but too late,
  5. hit the ground.

No damage to the IRIS+, but the Tarot Gimbal is broken. Hopefully I can repair it. I need input on why this may have happened.

Here's a video.

And attached are what I think are the logs? (first time trying to grab the log info)

I think the attached 2015-2-16_23-1_22.log may offer more info.

    I trashed all the waypoints on DroidPlanner prior to sending a new mission. I drew a simple splined plan heading south over the ice. I did a "SEND" Mission. I switched to AUTO (from Loiter) and gave a little throttle. Iris+ head for way-point 2 (south) but within a second or two it abruptly headed north into some trees. I tried to quickly switch to STD mode, but it all happened in seconds, so I'm really not sure if I actually switchedin time to have any control. It was on the ground very quickly.

      a better sequence is to give a little throttle, then switch to auto. It should do the rest. I will usually only adjust the stick when landing to find the best flat area for the gimbals' sake.

      If you were connected via DroidPlanner you should should have the logs on your phone. If you can upload them to Droneshare, the team can review them.

      Now that's service!!!

      Can you explain how I could get them off of DroidPlanner? I use a Nexus7

      Would this offer more info that the logs I've attached (which were downloaded from the Iris using APM)?

    When you say lifted in Auto; did you give a little throttle then switch to auto? Were there any previous waypoints in MP2?
