Can the ArduIMU V3 be used alone?

Greeting diydrones,

Before I'm buying the ArduIMU V3 I'd like to confirm a few things.

I'm interested in connecting the ArduIMU V3 to another Arduino and having the second Arduino control a quadcopter according to the data received from the ArduIMU. Can the ArduIMU provide the current orientation in respect to the ground and North(So I can use inertial navigation - I won't use GPS at first)?

If it is possible are there any guides/manuals that describe how to work with the ArduIMU V3 in that manner?

Thank you.

  • Hey buddy,

    What part of code needs to be change in ArduIMU_1.9.8 Firmware if we want to use ArduIMU running DCM on it without GPS..?

    Thank You..!

  • I just tested ArduIMU without GPS, to use it just for Heading, Pitch and Roll measurement.

    Results are bad, with big drifts on all values , but specially on heading.

    I use V1.9 software, I use magnetometer and speedfilt , setting  #define orders:

    #define USE_MAGNETOMETER 1

    #define SPEEDFILT 2

    Perhaps I made a mystake ?

    What about calibration ? I didn't find any information about arduIMU V3 calibration...

    Is it possible to get accurate values of heading,pitch and roll without GPS ?

    Many thanks.

  • Thank you for your reply, are there any output examples that include the magnetometer by any chance?

    For example in the screenshot here: http://code.google.com/p/ardu-imu/wiki/Demo the magnetometer chart is empty(First picture, bottom left part).

    Also, is it viable to use the ArduIMU V3 without a GPS module?

    From the wiki page:

    If you don't connect a GPS module, the IMU will still work but Yaw data will be unreliable since there is no way to correct for drift in the Yaw gyro.

    Which I find rather strange since it has a 3 axis Gyro, 3 axis accelerometer and a 3 axis magnetometer(Which is enough to correct drift on all angles as far as I understand).

  • I'm sure it can.    You would use the serial port to communicate between the two.   As far as guides/manuals... I don't know of anything available at all for the V3.    I plan on setting up a wiki with information when I get some time.  I will be doing the same thing of doing ArduIMU->Arduino soon.
