No crashes
Prop guards never contacted the wall
Cleared some debris
Yaw was very stable
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.
