That’s a $5 AliExpress drone with some felt attached to it. Good luck steering that in windy outdoors to pollinate hundreds of flowers. Flight time of 5 minutes. One blade of grass in the rotors and it’s done. The video in the article shows it essentially just bumping into the flowers. Saving the bees will be a lot easier than getting this to work. So if this is all we got, let’s just forget about the robotic bee. Let’s just really save the real ones.
