Make your own drone.

Jarfi

I've been having this urge to create my own flying robot, quadrotor or something similar with motors and rotating blades, I've thought up how it would fly, turn, and be powered.

Still some problems like, I wanted to connect a camera to it, but how do I transmit video over distance, is the internet the best solution? I also planned to use a normal remote controller I had for a remote controlled boat, And than making the antenna better so it can work to better distances.

But are there any websites where I can buy materials, where can I buy materials to create my OWN machines, and where are there guides for programming and such.

I'd love to study engineering, but I'm going for physics so this kind of is forced to be just a hobby, unless I study both witch is probably impossible.

Why not buy an off-the-shelf one instead? Designing one from scratch can be a very complex problem, especially from a control system standpoint.

Jarfi

yes well that was the main problem, I have thought up a design I love, with camera placement and stuff, but it's just control system and programming that ****s with me.

Travis_King

You could always buy one for the controls and data transmission/recieving and redesign it (and add to/edit the controls as needed)

Jarfi

Yes that sounds pretty good, but how would one transmit video over perhaps a kilometer, i've thought of the internet and wifi, is transmitting video from a camera over to you pc hard?

Mech_Engineer

Wifi won't have the range you want without directional tracking antennas. You're probably going to have to use some sort of analog video transmission hardware, similar to what's already used in OTS drones.

Jarfi

That sounds expensive, but maybe I can order said equipment on the internet. The reason I want to do it myself is because I want to make a prototype of my own design, it's not a quadrotor.

Here is a website dedicated to having a camera attached to your aerial vehicle and wireless telemetry for it (FPV): http://www.fpvpilot.com/Pages/GettingStartedinFPV.aspx

Control system? Here is an easy off the shelf solution: http://www.diydrones.com/notes/ArduPilot/

Website to learn more about designing and building a quadrotor: http://www.instructables.com/id/Quadrotor/

You will need some sort of long range transmitter/receiver package. Something like this I recommend as the absolute minimum: http://www.spektrumrc.com/Products/D...ProdId=SPM5510

You will have to take all these pieces of information and place them in your design. You won't be able to provide solutions for high data video transmission or design an embedded control system on your own without a suitable education. Good luck.

It won't be the most expensive part of your setup, especially when you look into flight control electronics.

Jarfi

Thanks alot, but how would I go around and build my own airframe? prefferrably from light materials like plastic and aluminum, I have the shape thought up but would probably need to draw it in a program, but is there a service that can custom make parts you ask them to do? can you buy things like that? because I can't mold plastic myself.

Mech_Engineer

Of course there are lots of machine shops and engineering services around the world that could fabricate things for you, but if you're worried about the cost of some off-the-shelf video transmitting equipment I don't think you'll like the quotes for fabrication costs either...

I think your best bet is to learn how to make a custom airframe out of balsa wood and molded plastic. Check out some RC plane forums for tips on how to build a small aircraft from scratch.

Jarfi

balsa wood sounds good, but is there a program, cheap or free where I can draw my design, motors, battery placement, aiframe etc, like you see in youtube videos. Where I can simply make a virtual copy of my design, than work from that, because i want to get this accurate

If its not a quadrotor, what will it be. You may need to build a control system? For building the airframe, look into rapid prototyping methods. For creating a computer model checkout Google SketchUp. I think it is free.
