Hi
I am doing a project to control a robotic arm based on acclerometer values. But I have euler angle and ypr but they are affected by gimbal lock . I just want only roation around x, y and z which are not affected by gimbal lock.
What does that mean?
Are thinking about the axis/angle means of representing a rotation operation?
Is there any way get rid of gimbal lock.
In my previous field of employment, the phrase "Gimbal Lock" was used to describe the position at which a moving (in my case rotating) mechanical component hit an end stop such that it could not go any further in that direction. Is that what you mean here?
Use the quaternion to represent the orientation, like everyone else.
You can’t use accelerometers to give you an accurate position !
Any noise on the signal gets integrated up causing drift or position error
actually i read some online 3D converters javascript files. It covert quaternions to axis angles with magnitude. Axis angle does not affect by gimbal lock . But when i change pitch from 0 to 90 there is change in roll from 0 to 10 or 0 to 20 it varies. I conformed the axis angle convertion formuale by seeing the axis angle covertion used in teapot simulation. In simulation it show perfect rotation but i used same axis angle formulae in my arduino sketch.
i am using mpu6050 quaternions values
