Question

Asked by: Timothy
Subject: summing X, Y and Z gyroscope values
Question: Hi,

I am using an electronic gyroscope and I want to calculate the degrees the device has turned regardless of any angle changes whilst it is turning. So for example with the Z gyroscope I can calculate a 90 degree turn accurately, but of course when I tilt the device, the Z gyroscope readings slow down relative to the angle. The steeper the angle the slower the readings. I guess tilt compensation is possible using trigonometry, but I have tried various things and I have not been able to get it right.

I want to be able to measure the degrees turned around a particular axis regardless of how the device is tilting during that turn.

I have also tried summing all the X, Y and Z values together, which might work but the gyroscope values change during any angle change, and that is added to the equation.

any ideas?

thanks
