[PhysOrg] Researchers build flying robotic 'tree helicopter'

post #1 of 11
Thread Starter 
Quote:
Many trees disperse their seeds by releasing "helicopters," those single-winged seeds that are also called "samaras." As these seeds fall to the ground, their wing causes them to swirl and spin in a process called autorotation, similar to man-made helicopters. In a new study, researchers have designed and built a mechanical samara whose dynamics are very similar to those of nature’s samaras. After testing the mechanical samara, the researchers then built a variety of remote-controlled robotic samaras with onboard power sources.

I thought i was pretty cool, and figured I'd share. Couldn't find on search.

Ok, that's hella cool. It's such a simple design these could be produced in mass for peanuts.

That's definitely cool, but what would be a practical application for this device?

Pretty neat, but as for practicality I would say this was more of a stepping stone for other research

Who knows. But it's cool either way. The part I think is most interesting is that it won't ever crash if it has engine failure. It'll just spin, eventually hitting the ground.

Oooo, that gave me a great idea... This will be the design for new ejector seats LOL!

I used to have a maple tree in front of my house that dropped samaras. I used to play with them all the time when I was a kid. Awesome article!

Practical applications? A device small enough to be carried in your hand, damage-resistant, easily navigatable and rechargable which can carry any number of optical, thermal, or chemical sensors would have countless applications in military operations.
