Really cool jellyfish robot

[Caduscus]

I know i know, it's not REALLY a robot because it's RC but It still is really cool, and i'm thinking of making something like it, with a bit better of cotrol, automous and such.. Might have seen it before but I thoguht it was awesome, simple but awesome..

Here's link to website (in another language, french i think) - http://www.festo.com/cms/de_de/5890.htm

This is really cool!! It's in german actually.

Air is the element of AirJelly. The remote jellyfish AirJelly not swim through water as Aqua Jelly, but glides formally thanks to its central electric drive and an intelligent, adaptive mechanism by the sea air. Because AirJelly consists of a helium-filled Ballonett.

 

As the only energy source AirJelly two lithium-ion polymer battery to which the central electric motor is connected. This will transfer the power to a bevel gear, and then successively to eight front wheels, cranks of the eight tentacles of jellyfish. Each tentacle is a structure with the Fin Ray Effect ® trained. The drive a balloon through a peristaltische movement is now in aviation history is not known. AirJelly is the first indoor flying object with peristaltischem drive. The jellyfish moves thanks to this new drive concept, its recoil on the principle-based drive, gently through the air.

That is the coolest thing I have seen ever!

and i thoguht it was french, I know a bit of german!!! Guten tag ,schiese kuchen... all the nessasary things

Thats a really elegant beast!

Its a shame it got to be filled with helium though (i wonder if something similar might work just filled with air or even a parachute type umbel?? possibly with larger paddles?)

This is another one made by the same company . . .

Unfortunately this company is really sneaky in video editing, with ultra closeups and short cuts, so I suspect these don't work as well as they look . . .

true

[BANE]

the first movie, does it have helium in it or something?

bane

[paulstreats]

Yes it has helium in it, though I have a feeling that something siilar can be constructed without any helium, if its very light weight and has just a parachute type middle instead of a big ball, If the paddles are large enough then there is no reason why it shouldnt work without

I don't think something like that would work if it wasn't very close to neutrally buoyant (I think the actuators would add more weight than could be lifted by the paddles alone).
