hello all friends,
Any one doing quadrotor using arduimu v2 as main sensor  board.

Not sure if you have seen this : http://www.rcindia.org/self-designed-diy-and-college-projects/quadrotor-build-thread/msg25381/#msg25381

I will start working on it again after I get back from my travels.

i started with this just now i finished with all my frame design and assembly and now starting with software part.if u dont know then for ur information arduino 0019 version is out now. It wil be gud for me that u wil start this project again

i made my quad frame from pvc pipes generally we use for electrical purposes in our home and used 4way junction to connect these arm the frame is light and very strong and mounted towerpro motor on that here are some pics of my frames

Nice idea. Any reinforcements for the pipes (or are they thick enough) ?

How was the motor mount built ?  Any close of pics of that ?

the pipe and the connector i used make really tight and strong connection but after connecting arm to junction i fixed it by feviquick so it makes permanant connection.for mounting motors i have used metal clips at the end of the pipes fixed it with hot glue and then placed a square piece of pvc foam maintaining the horizontal level with the help of spirit level and then mounted motor on this surface

here are some pics showing clip mounted on the end of the pipe these type of clip can be get frm any electrical or hardware shop.and the whole frame cost only around 50 rs. Just

from where u ordered a magnetometer for ur arduimu v2

hi anwar,
how u have connected ur receiver with arduimu v2 since on this board there is requirement of single ppm input.
currently i am using wfly 6 ch receiver any suggetion

Anwar's concern is the 'flex' in the boom/pipe. Usually these pipes would flex under its weight, introducing the bend. This situation could get worse under the motor thrust.

This would be important as any such bend would change the thrust angle of the props.
How well does the Gyro mixing handle such situation.

I still feel the Aluminum U/E Channels    are much sturdier and light.

You can tap out the PPM signal from many receivers, if you are good with a soldering iron.  The PINs where PPM output is readily available is documented for many receivers, and you can find the PPM signal on the boards of others if you (or someone you know) has access to logic analyzers. 

See this for details on many receivers : http://paparazzi.enac.fr/wiki/RC_Receivers_and_Radios

I went with the diydrones.com recommended solution, which is this :

Haven't tested it, but will solder it up and test it after I get back.

i have one, i did with arduimu

the thing i found is
1. lil diff in tuning pid
2. pid differs with payload
3. not good for outdoo :headscratch:r flight
4. very nice if you tune it for exact pid
5. every time you have to connect it to pc to change pid 
6. serial input is needed

its ok and its open source
i did with 72 futaba converted in to serial .. now im gonna try with corona

hello anwar,
can you tell me any source for magnetometer sensor for arduimu v2 since i can't shop it from diydrones becouse i dont have credit card.
can you tell me any source for it in india,
since i will need it for my yaw drift correction.

thanks.

For buying Magnetometer in India I found these two sites and rates are also quite cheap.

And if u r interested you could invest in a COmplete 9DoF board buy Sparfun with Acc/Gyro/Magneto (all 3 Axis) on a single board
check it out

I hope this Helps... 

hi anwar i got really great thing from paparazzi site that  is the ppm encoder design whice is built without any microcontroller means no programming.it is built using cheap and simple analog components see under other hardware section on paparazzi u wil get meekpe ppm encoder. I am going to build that one. Pls keep posting about further work

i have one problem with programming when we open 1.7 version code in arduino-0019 the we see different program on bar like arduimu,adc,dcm and many so do i have compile and upload all the programs. I m using arduimu v2 with magnetometer.pls help me out.↲ thanku

I can't see how they are cheap.  The magnetometer listed is only 2 axis one.  The IMU listed will need an extra Adruino (I believe) to process the sensor information, right ?  Then its pricing also becomes less attractive.

If you have bunch of .pde files in a folder (the code seems to be shipped that way), then you just load the main .pde file, and it opens up a bunch of tabs with the various sources files (basically these are all various sub-systems).  When you compile and upload the arduino based board, it should all get compiled together and get uploaded (as there are references between them that the compiler handles behind the scenes).

What i meant was that the IMU is quite cheap when compared with Other systems with all Sensors integrated. And if one knows hoe to program on Atmega32 then they dont need another arduino instead could program there while system onboard itself, but this is not recommended for beginners so they could buy any arduino which would make their whole electronic control system within Rs. 10k


For comparisons....

are there any Indian vendors for ArduIMU.?
And is it possible for the quadrotor setup of Arduino UNO +zigBee+arduIMU.? or I can go for higher boards of Arduino other than UNO..?

Go for arduino 2560 and you can have a MegaPirates NG platform. This means you have a readymade open-source code, a cool GUI with a missionplanner. Just make sure you use MegaPirates supported sensors on your IMU.
