hello there,
i want to build arduino quadcopter but i have some prublems, because it's a first time for me building any kind of flying machine. i have already purchased some part:
1) arduino uno
2) frame x525
3) 4 - Turnigy D2836/8 1100KV Brushless Outrunner Motors
i need your help. what part i need to buy next? keep in mind that i have tight budget, so i am searching for low price esc and other materials.
ps. is that possible to control this quadcopter directly from smartphone?
Be ready to sift through a few thousand lines of code trying to get the thing just to lift 2 inches off the ground hahaha. Believe me when I say that once you get it to take off 2 inches you will cry from pure joy, and at that moment it will flip or fly into something and destroy your last 70 hours of work. That is pretty close to true even if you use an off the shelf flight controller, but a lot more so for anyone making their own FCB.
If you are persistent and just want to do this then I can provide a little, but don't expect this to be any cheaper than getting a flight controller of the shelf. As a matter of fact expect it to be more expensive, so that the only reason you are doing this is for the experience or an assignment of sorts.
A flight controller needs to make several changes per second to just hover, so don't try to just tell all of the ESCs to spin the motors the same speed, as you won't get all four legs off the ground.
I don't say any of this to discourage you, but simply so you have an idea of what you are getting into.
Now that little bit is out of the way, yes you can control a quadcopter with a smart phone, but if you use 802.11 or 802.15.1 standards (WiFi or Bluetooth) you won't get a reasonable range without some sort of modification.
Here is a list of some things you'd need
- Flight controller
- ESCs to control the motors that are 3 phase
- brushless motors
- frame
- props, 2 clock wise and two counterclockwise
- power distribution board or cable
- lithium polymer battery
- BEC (often built into the ESCs)
- Radio
- Reciever
Some other things
- A lot of zip ties
- solder
- flux
- solder tools
- heat shrink
I suggest you make, or buy a simple flight controller for stabilization and then use your smart controller to go between the receiver and the flight controller so that you are working with a lot simpler method of interfacing with the FCB. I also suggest you pickup a cheap FCB to test with because you are going to need a way to test that your hardware is all working before you start getting into stabilization problems, otherwise you start treating symptoms and everything becomes such a mess you have to quit and start over.
