I'm using an integrated 6DOF Inertial measurement unit called the ArduIMU+ V2 that consists of 3 axis accelerometers and gyros. Currently the set up is that the accelerometers are also measuring static acceleration (which is something I want to get rid of to obtain only dynamic acceleration). Does anyone know how I can do that?
Another difficulty encountered was that at first when I started up the IMU board, the accelerometers seemed fine and after conversion, the z-axis is in the positive downward orientation reading about 9.81m/s^2. However after some time in operation the accelerometer suddenly became -9.81m/s^2. Does anyone know a likely reason for this? Noise from motors (Electronic speed control)? Erroneous programming? Or other things I could check out?
Any help is much appreciated!!
