Here's a clever way to "perch" and land quadrotors, using propeller guards instead of "feet". It requires reversible motor electronics, but other than that it's simple and elegant.
For "perching" on a ceiling, the drone simply flies up against the ceiling. The prop guards prevent the props from actually touching the ceiling, but the props are still close enough to get extra suction.
To land, the drone goes upside-down.
It's an interesting approach, but I think suction cups would be even better and more stealthy.
As a side note... The presenter sounds very AI-generated.
@VikingChieftain Maybe so. Suction cups are pretty fiddly, but it could easily be worth integrating some small suction cups into the prop guards.
I don't know if the presenter is AI voice. Could very well be, but if you look at similar academic videos from years ago, they all tend to have this same sort of voice. Almost purposefully robotic sounding.
Ideally, you would want the FPV to rest in order to save batteries. However, suction cups, with or without a vacuum pump, would add weight and complexity. But I like the concept they presented. It wasn't their original idea, but they gave a consistent presentation of it.
With so many AI slop videos on YouTube nowadays, you start to get paranoid when visiting a new channel. You start to wonder, "Is this a real person, or is it an AI-generated voice from an AI slop shop in Bangalore?"
