ARDUPILOT SENSOR BOARD - SIX DEGREES OF FREEDOM (MAIN)
The Arduino-compatible IMU is a project by Chris Anderson and Jordi Muñoz to create an AHRS (attitude heading reference system) for UAV control and general motion capture. This is the main board for the ArduPilot 6DOF. By itself, this board works as a 4DOF -- it produces three axes of acceleration and one axis of angular velocity data. This board can be connected to up to two ArduPilot 6DOF daughter boards which will each add one more axis of angular velocity information. The main board can be connected directly to the ArduPilot analog pins.

Link Any one has this ?

Hi,

I have 6DOF razor with Arduino Duemilanove , i am using connection and DCM code provided here http://voidbot.net/razor-6dof.html
I am working with graphics in VC++ .I have a 3D rectangle drawn in my program.DCM code giving integer data of DCM. How to map that data to get exact rotations( i need to multiply DCM with Modelview matrix of OpenGL to get rotations). At present i can't be able to use that data correctly.

Thanks in advance.

Hi everyone,

 

I connected the x4 amplified gyro outputs to the analog inputs of Ardupilot Mega. I'm checking the outputs on the serial monitor. In still position they indicate about 250 which is equivalent to about 1.2 volts, it should be ok. The problem is that when I move it, slowly or sharply, I get very little variations, e.g. the reading drops to 230 or goes up to 270. What am I doing wrong?

 

Cheers guys
