Robotic Airship, some ideas :)
September 3, 2008
So i was looking at some flying robot designs, just out of curiosity. I ruled out helicopters and planes: they require too much precision in crafting and are too complex.. But alternatively an airship could probably be built :)
I've read on wikipedia that a square meter of helium can lift about 1 kg. A square meter means a big balloon, but a Kg is plenty of weight for electonics!
If you use light components, you can probably stay under 0,5 Kg or even less.
For the balloon, one of the cheapest way would be to use a condom :P They're strong and light and cheap, the can be inflated to a cilinder that, with some inprecise calculation i did, could host about 0,1 square meter of gas. One could use two or three and have planty of lifting power :)
So the question is: am i completely crazy ?:P
No really, do you think this design could ever work? Of course the best would be to have something that can be controller outdoor, but i think it would be too much..
