I have recently recieved my Raspberry Pi.( a small computer which can be programmed)

I plan to make an UAV( just a trainer which does not use a remote control)

 I plan to run it on GPRS internet connection

The problem is that i cannot find any source of depron, or coroplast

Can i make it from thermocol sheet which we get in stationary shops?
if yes, how to make the wing out of it without using hotwire cutter?

 

You might want to go through the videos is this build;

Ayub wonderfully uses a hacksaw blade for the coarse cuts and sandpaper to finish...I've tried 120 grit sandpaper on thermocole and the results are amazing. I doubt you will be able to use thermocole available in stationery shops, it will break away easily. You will need packaging thermocole which is higher density

Thanks...
will use it...

Just while going down the road today, I notiiced something... There are a lot of advertiesments on electric poles and trees...all made u of coro... ...... a free source  of coro there...then i will use a mixture of both coro and thermo...

A raspberry pi to control an uav? Details??
A word of caution when using thermocole. Avoid the ones they sell at stationary shop, they are pretty useless. If you can, get high density thermocole from the art stores. They are great for making planes.

Didn't yet program the RPi but the idea is to just eliminate the tx /rx and use a gprs 2g internet connection on a trainer plane..which can be controlled from any other phone, tab, laptop or desktop

Got some coro but having a difficult time working with it...any suggestion?

You will find that it is very hard to do. And quite unreliable. But still if you can make it work, it would be quite cool

Google spadtothebone. They have a lot of info on working with coroplast.

In which part do you find it Difficult to work with in Coro.

Cutting it and sticking it...

I think if I can atleast make the plane, i can take help of some experts for programming...

My idea is to make a blog on a  free web hosting website and post the command to it so that the plane can read it...I don't know wheter it would work effectively for an agile vehicle like a plane but...it must work....

I remeber that some time long ago, I read that website but forgot it... thanks for reminding...

Any hobby knife will do the trick.
Anabond sticks Coro well.
make sure it is dirt/grease free.
a 3mm coro is good, dont buy a 5mm one its way too heavy.

Don't use the raspberry Pi on its own. Get the ioio board along with it. Keep in mind that the Pi will have some latency in responding, so it is not suited for physical computing. You may look towards an Arduino + GSM combo for the control of the plane and a Pi to handle the navigation.

One thing to keep in mind while working with coro is that you MUST flash or sand the surface thoroughly before gluing.

Happy ganesh chaturthi to all... after a long time came back to my project... created  a part of the fuselage and reinforce it with some light sticks... one thing I am confused is that my fuse is flat and doesn't look even clase to an airplane.. I want it to be 3d ... what to do?

A few pictures...

Change the name of this thread

Pl hear what sanjayrai55 says.
Pl refer to recent discussion going on in this forum about whether we are flying model airplanes or UAVs.

I agree that "Drone" is a term that should be avoided, but why would one not call a model airplane, used for some other purpose, an Unmanned Aerial Vehicle? Yes, I agree the media has given UAVs a bad name, but still if I use my aerial rig, be it a quad,plane or a blimp, for, say, collecting some weather data, then why should I call it by any other name? I am not defending those people who slap on parts together and call their contraption a drone, just to get publicity or marks, but we should atleast be able to call an UAV an UAV.

Sir,
This has been discussed.
All are UAVs, including HLGs.
We (at least some of us) are only suggesting please consider not calling our models UAVs as
perception of public/media/maybe Govt too is that UAVs are DRONES.
However, to each his own.
Request is to please protect hobby flying from potential restriction.
Remember there was a time we used to fly from Safdarjung.
And from Polo Ground with one VVIP. That is all long gone.
Used to fly from Parade Ground, Secunderabad early 90s. Presumably gone? One lady owner of a flying school may remember her days there with her brothers.

The tem UAV has a clear connotation in Defence and military terminology. It could draw the wrong kind of attention. As Iyer sir remarked, all RC aeromodels are by default UAVs; it is the perception of what a UAV is in the eyes of lawmakers and enforcers that could draw unwanted attention, from which we as a community would suffer and therefore should strive to disassociate with.

I thought it was so obvious to anyone in this forum.

I have never called anything I built/assembled an UAV.. I refer to them as "flying thingy", but for any formal application for any kind of sponsor/competition/academic paper, the word UAV is always more preferable to "flying thingy" or "model airplane". So people like me are caught between a rock and a hard place Maybe we should all get together and dream up some other name for the things we make which are not quite model airplanes but cannot be called "UAVs".

I apologize to the OP for hijacking his thread

UAV's in particular is a vehicle which can fly all by itself without human intervention.
this being said in our hobby RC flying its us who gives command, even though their is no pilot in d plane its us who is called pilot.

So we just cant call the rc plane as a UAV.

UAV is a plane which does things we ask it to do but flies by itself

correct me if I am wrong...

topalle
For making rc plane get 3mm not more than tat.
u can use cutters n hot glue or u can yous tapes...
I recently did a 1.5mtr glider with coro and it flies well...

I am afraid you are wrong VTOLkarthik.

"An unmanned aerial vehicle (UAV), colloquially known as a drone, is an aircraft without a human pilot on board. Its flight is controlled either autonomously by computers in the vehicle or under the remote control of a pilot on the ground or in another vehicle."

From wikipedia.

Ya ofcourse it is controlled by systems from the land but its flight stability and object detection are completely done by the on board controllers which is not handled by human.

drones is one more thing which is usually used for single purpose and its flight is controlled by controllers from the land...
