  • Throttle was very stable in stabilize flight mode

Issues

IMU Issue

  • We need to look into the IMU center drift issue which made piloting difficultWhat was the issue:

    • The drone’s definition of level would drift over time.

  • Resulted in

    • Pilotting became more difficult over time as pilot would have to hold a constant stick input to maintain level flight

    • We landed on the ledges accidentally twice when the drone was harder to control .

    • Lots of time having to land on the ground over and over again so the drone could reset it’s definition of level flight

  • Possible Solutions (we can test these and may brainstorm more)

    • Being able to use controller trim during flight may be able to resolve the issue without landing.

    • Disabling all compasses may help.

    • Changing IMU settings may help.

  • Why we didn’t catch this sooner

    • All our other tests were outside and away from large metal obstacles so this condition did not arise as severely as it did.

  • What caused it:

    • Flying near the metal walls seemed to cause the center drift to become much more severe.

    • Doing sharp stick inputs when in the middle of the event space did not cause any problems.

    • Flying near the concrete didn’t cause much problems either it seemed.

    • We have videos showing this

      very clearly

      , maybe review those and don’t trust us so much.

Debris Removal Issue

...

  • Resulted in:

    • The paper airplanes get stuck under the metal piece on the edge of the wall and it means even though we’re blowing them up a bit the nose tip remains still stuck in the crevice.

    • hard to clean the paper airplane on the corner/beside the wall

    • sometimes we blow the paper airplane to those spots as well

  • Possible Solutions (we can test these and may brainstorm more of course)

    • propeller direction config such that it sucks objects instead of blow them away?

    • A different approach.

  • Why we didn’t catch this sooner

    • This was our simplest possible approach and we weren’t too sure how it would go

      • that is why we have this test flight !!

  • What caused it:

    • the propellers blows the stuff outwards

    • It’s tough to get close to the wall to avoid blowing stuff closer to the wall

Next Steps

  • Look into issues.

  • Email Derek & Dennis to update them of our status.

  • Try again on Friday evening for another test flight.
