Obstacle avoidance message @ 250 ft open area?

[madkaw]

Perhaps some of you experienced flyers can provide some explanation. Well, I flew the mavic today in a open area, about 250 ft up and a message pop up “obstacle avoided”. I return to home point, and viewed video but nothing was there. I’m thinking maybe a bird flying by???

Where you flying into the sun or close to it ?
That will set it off.
Unless you cannot change direction a bit to avoid this, you need to ‘crab’ it home or fly backwards.

I agree with @MAvic_South_Oz ... The Mavic is famous for this one ... If you are aimed at the sun, that can trigger the front obstacle sensors ...

 

[madkaw]

I don’t know, it was 65% cloud cover and no visible sun, but there is a chance that a stray ray may have confused it. Just thought other have experienced this issue before like a sporadic glitch( happens occasionally type deal)

Stupid question - are you sure you have removed the clear plastic protective covers from the front-facing camera's??

Erroneous obstacle detection is pretty common.

Yes, the gimbal cover was removed.

Copy, had a feeling, but wanted to see if others have experienced or heard of this. Btw it doesn’t happen all time, as a matter of fact this was the very first time.

Common problem when flying into sun.

 

[FoxhallGH]

Yes, the gimbal cover was removed.

Nope - not meaning the Gimbal cover ... The two small forward facing obstacle avoidance cameras on the nose of the Mavic have small transparent disks of plastic pressed onto them to protect them during shipping. If you have missed taking them off, they could be causing you a problem ...

Like said, direct sun is a well known culprit.
I’ve had mine do that for absolutely no reason also. Bug, hummingbird, whatever. But the most interesting was the time it was snowing lightly and a snowflake lodged in one of its “eyes” forward sensors. Wouldn’t budge until I disabled OA. Light rain will do the same. Anyway I’ve got to where I usually just fly without it unless I’m low in an environment where it might save me, as it is very sensitive.

Better to not use OA all together. It's a false safety feature that can cause people to fly into things because they trust it too much.

Actually, a valid point. I can see it being a benefit in an emergency RTH or something similar I suppose.

On the couple of occasions this has happened to me on the MP it stopped and would not go forward. I backed up a few feet and it then allowed me to continue on. I actually had this happen last week on the M2P which surprised me.

Gotcha, it’s been removed long ago.

That’s how it happen, did exactly what you did and all is fine.

Right, had too be a insect or bird fly by.
