What's up with Bees and Drones?

I was flying my drone today, higher than in the past, and upon decent I noticed insects, bees, swarming around it. They were descending with it. What? When it landed and shut-down they scattered. There were bee parts all over it. In flight, I could hear them hitting the props. It would make a sudden change in the sound. I thought it was just the wind.

I don’t want to harm bees, but what to do about it? It seems like the sound is the culprit. I wonder if they were attacking it or if they were simply attracted to the sound? Has anyone here had this happen?

Interesting, Bees are rapidly becoming endangered species. Perhaps you should keep your drone on the ground

I know not to mow the grass next to a hive. It is swarm season and they may have been protecting their Queen.

Probably attacking it as the frequency "bugs" them...

Drone buzz?, another <big> "bee" invading?

I realize that you are asking a serious question about a real problem. But I will still confess that the thought that popped into my mind was that you should consider a wireless drone with a silent propeller system.

In all seriousness, I wonder if craft with ducted or otherwise protected fan type propeller systems would generate enough less noise to reduce the problem. They might also physically protect against collisions.

Have a look at toroidal propellers.

They are a very new development, and they change the sound frequency considerably, to a lower pitched much less annoying sound. The audio perception is that it makes the drone much quieter, although in fact the dB rating is the same.

At this point, they are not yet commercially available although there are a number of people 3D printing them.

Unfortunately, they don't fold, and - for your drone - would increase it's overall size, meaning to keep it pocketable, you'd have to take the props off & put them back on each time.

I will be trying some on an Avatar, but for the reason above, won't experiment with the Mini 3 Pro.

This video has some insight - https://www.youtube.com/watch?v=F7FN29m8zfA (9:58 length)
and the comments hold some insight also...

Very interesting, especially the part about low frequency vibrations.

Thanks for posting.

if only that existed

The ducted fan is a good suggestion! That will help protect the bees and might reduce the noise. I think they are available for this model! I will look into it! Thanks Larry!

Interesting!
For me size is not a crucial issue so that might be a good mitigation to the noise issue!

Have a look at https://www.ll.mit.edu/doc/toroidal-propeller & https://www.youtube.com/watch?v=qsfnlUuKH8Q


This one is interesting too: https://www.youtube.com/watch?v=z_d9Nt_8FWg

What a unique idea! I didn’t think of that. But since it’s an aerial camera, that’s it’s purpose, how could it take aerial pictures from the ground?

I’m actually sensitive to the bee 🐝 problem. I don’t wish to harm them. Fortunately several here have provided excellent suggestions that might eliminate that problem.
