Wooovie… I just surfed
Wooovie… I just surfed some vids on youtube for arduino and xbee and it’s not that hard just fantastic. I think wont require 6 months of study. just a month is more than enough. just help me in that rc remote connection.
I saw a vid where a guy controlled a servo with 2 xbee’s and 2 arduinos. but if i am to use this remote will i still require 2 arduinoes? or will the rc remote replace 1 arduino?
I am good with c language which is used to program arduinoes.
so coding wont be a problem but still be there to guide me.
ya 1 more thing I wanted to ask that does different types of arduinoes are able to communicate with each other? because in the aircraft I will need a small arduino. where as the transmitting one I may use different one.
Hey Chris! you there?
Wanted
Hey Chris! you there?
Wanted to know that whether i wont need 2 arduinoes?
or should i forget abou that transnitter and just use 2 arduinoes, 2 xbees , 2 arduino xbee shield.
and design me own transmitter?
do you have a good transmitter anywhere on the net?
Chris explained that the
Chris explained that the transmitter you posted includes a brain already, so if you use that you will need a 2nd brain (like an Arduino) for the receiver.
However, if you want to keep all of your coding in the same environment, you could forget about that transmitter, and build your own with an Arduino and XBee. This way both your transmitter and receiver are programmed in the same language.
Thanks v. much this is what
Thanks v. much this is what I was confused about. as its my first time.
do you know any transmitter without a brain.
so that it would be easy to pass data to arduino?
thanks again
Which arduino should i
Which arduino should i prefer.
As there are many versions available.
which 1 would be just perfect.
also can different arduinos at the receiving and transmitting ends work simultainously?
It doesn’t matter which
It doesn’t matter which Arduino platform you use, they will all work together, including the many open source clones that have been created.
For your aircraft, you will want something that is small and very light. You might want something like this:
Thanks for the suggestion. i
Thanks for the suggestion. i looked into it. but u see it’s my first UAV So i am not going into much technology in it but aiming it to be basic. also being my first budget is a bit low.
thanks
Please help me in the transmitting end.
where can i get 2 joypads to control my 4 servos. like an rc transmitter.
Thanks for the suggestion. i
.
Huh?
What happened to the transmitter you were looking at?
As you said that transmitter
As you said that transmitter already has a brain in it. and at the receiving end its gonna be arduino. so if i get arduino at the transmitter then things would be easy i think so…
so i am looking at a transmitter with just 2 Joypads ans couple of switches. so that i can take that as input for the arduino.
how many conponents an arduino can handle at a time?
say maximum hou many servos can i control by an arduino?
From a software perspective,
From a software perspective, the standard Arduino Servo library can control up to 12 servos for most boards and up to 48 on an Arduino Mega. The Software Servo library can control more. Read this for more info.
From a hardware perspective, the Arduino can only supply so much current. So if you have a lot of servos, you need to provide them with another source of power. Read the info on the hardware section of the Arduino site, or the specifications for whatever board you decide to use.
Great. sooo basically if i
Great. sooo basically if i use ardu. nano in the aircraft. and ardu. uno in the transmitter. then it wont be problamatic.
so i can hookup the 2 joysticks of the transmitter to control 4 servos which will be controlling the rudder. ailrons ( spell may be wrong) for complete control on the aircraft.
and a simple potentiometer to control the brushless motor propellor.
the two joystics on the transmitter are basically 4 potentiometers arnt they??? it m not wrong.
the center position of the 2 joysticks will correspond to the center position of all the 4 servos. and an additional potentiometer which most probably i will mount on the right side of the teansmitter will control the speed of the brushless motor. so the whole aircraft will require in all 5 motors. ie 5 potentiometers to.
i was thinking of ardu. nano because its small and can be good for the aircraft where space matters.
what suggestion and do’s and dont’s you would like to tell me before i actually start all the work.
You are correct
You are doing a little trade here. The transmitter you were looking at would have been “all connected together” and ready to go, but it does work off of a AVR chip and would rrequire you to learn another language.
The Arduino/arduino set-up will require you to do a little construction and wiring but in the end, both the TX and RX will be speaking the same language. Easier to code.
You got everything right in terms of the pots inside of the joysticks. At this point, the first step would be reading the joysticks via the ADC inputs, translating and confining the numbers so they will work for servo commands, and then setting the servo positions. When this is up and running, you can work on the data transfer from chip to chip and then just “divide up your code” --the ADC and joysticks on the TX chip and the servo stuff on the RX. UART serial via X-bee in bewteen.
Okay then. everything about
Okay then. everything about the heart of the aircraft is ok. and it ought to work. my ideas are clear about the electronics. now we should thing about the design. the only thing i know about the aeroplanes is how they can fly. and its because of the special shape of the wings. but rest that where the wings should be placed. where the cg of the plane should be. and all is a thing i need to work upon. any suggestion guys??
The brushless motor i am
The brushless motor i am choosing says it gives. 1.235 kg thrust. Does it mean it ll make a 1 kg aircraft fly?
Flying…
Wait a sec,
Have you not flown a model airplane before? (With regular RC.)
hmm wait a sec… hmmm let
hmm wait a sec… hmmm let me try to recall… hmmm
NO
Well, you seem to have
Well, you seem to have ambition and enthusiasm. Unfortunately that doesn’t always make up for experience and knowing the fundamentals- there seem to be some holes in your basic knowledge. Are you sure you don’t want to attempt a smaller scale project before diving in on this? If nothing else it would be an opportunity to learn about the mechanics, electronics and basic problem solving without a large initial investment.
Wow, I think we might be skipping ahead a bit.
I don’t want to rain on any parade here but I should note some facts.
It is pretty hard to learn how to fly an airplane in the “normal” way. You are guaranteed to crash, you WILL loose a plane or two and it will take a few months of practice to really get going.
This being sorta your “first” project, there is a HUGE amount of uncertainty in terms of your code, wiring, installation etc. Not to mention, the affects on the plane of removing the “stock” gear and replacing with homemade stuff --CG and ballance for example.
If I were a betting man, I might put money on one or the other but not both. If you were an experienced pilot and newbie at electronics, you could probably pull this off. If you were an electronics guru but had never flown, again, you could probably do it. As we stand now, you at some point are going to be at the field throwing a plane into the air. After the crash, you now get to ask:
- Did my code fail? Did it burp somewhere or get locked-up?
- If it was code, was it the tx or the rx?
- Was it any of the wiring on either side?
- Did the x-bee’s go out of range?
- Interference?
- Was the plane improperly ballanced because of the new stuff?
- Did either of my power supplies fail?
- With all the new electronics, was there electrical noise that brought the plane down?
- –or–
- Did everything work just fine and you simply crashed a plane?
You are about to buy a $200 plane, and stuff $200 worth of parts into it. Then you are going to throw it away --Not “throw it away” like it was trash, but literally throw the plane and it will fly away from you. And keep flying away from you. The only thing that will bring that plane, and your parts, back is your code and pilot skills. You are a newbie at both.
Once again, like I said before, this project is doable. I do however, think that you are skipping WAY ahead right now. I can almost guarantee that you will have 2-3 months in just learning the code and getting it solid. You have GOT to make a LED blink, my friend. Once you do this simple thing, you will have a taste of what you will need to do to finish this project.
I’m going with CTC on this one
You should get yourself a cheap ready-to-fly airplane kit made of foam, learn to fly it and while you’re at it, get yourself a flight simulator program that you can use with the RC unit from the plane. (Look for protech stuff, they have some nice kits with a sim program and a simple plane).
Once you get that down, once you are really able to fly a plane without it falling from the air in a split second, get yourself some knowledge on building a custom airplane and use the gear that came with your kit.
While you are doing that, take some spare hours and familiarize yourself with the Arduino and electronics.
Make a led blink, make a speaker beep, get servo’s to move.
Try interfacing with the XBee’s, make a couple of servo’s move on your desk while controlling a motor, and so on.
If you have no (or little) knowledge of either flying model planes and of the electronics you want to use, this is going to cost you alot of money, time and frustration.
I have been playing with model planes a while ago, really cheap ones, and none of them is alive, since I didn’t want to take the time to familiarize myself with everything that comes with it.
Trust me on this one man, take it slow. Ambition is cool, ideas are exciting, but work to it slowly before you throw all your money into a pit that has no bottom.
