Hello guys. I'm trying to build two projects that use input from gyro and accelerometer.
The first one is a self balancing robot and the second is a quad-copter.
Both acc and gyro have internal filtering. Low-pass filter, High-pass filter and base-pass filter.
My question is, which one should a choose for each project?
I think that for the self balancing robot I should choose a high-pass filter, since I expect low frequency noise coming from it. And if I'm right, which cut off frequency should I choose?
Acc: - 8 low-pass filters: 10, 20, 40, 75, 150, 300, 600, 1200 Hz (no dig. Filter) - 1 high-pass-filter: 1 Hz - 1 band-pass-filter: 0.2 – 300 Hz
Gyro: Low-Pass filter: 256Hz, 188Hz, 98Hz, 42Hz, 20Hz, 10Hz, 5Hz
And for the quadrotor, which type of filter should I choose? My thinking is that high frequency noise will come from it, so I should choose a low-pass filter.
Is that correct? I'm new to noise filtering so I'm a bit lost.
Can anyone help me? Any suggestion will be appreciated.
