Hello again :-) My quaternion to angle conversion seemed to be completely wrong. Does anybody know how to convert the Quaternion from Body->GetAngularVel() to degrees / second? I tried a lot of formulas, but they all don't work. The output becomes smaller and bigger although I run it with a constant rotation speed. So the angular velocity also has to be more or less constant, doesn't it?
Thanks in advance Jonas -----Ursprüngliche Nachricht----- Von: Gazebo developers <[email protected]> Gesendet: 23.10.07 19:46:05 An: "Gazebo developers" <[email protected]> Betreff: Re: [PlayerStage-Gazebo] Simulate gyroscope in gazebo Yeah, the drift does seem to be a problem. Are there any mathematical models for drift, or simple ways to estimate it? If all else fails, maybe adding a little gaussian noise will do the trick. However, take that with a grain of salt, I'm no expert on gyroscopes. -nate On 10/23/07, Jonas Lanvers <[EMAIL PROTECTED]> wrote: > Hi, > > The object does not have to spin.
