I'm learning about Gimbal lock and I understand the reason why that happened.
But I don't understand why that is a big deal because it only affect this rotation. After this rotation finished, we have 3 new axis to rotate from, so we get back our 3 degree of freedom.
And if the resulting attitude is not what we desired, doesn't that mean we have the wrong Euler angle? which imply that the middle Euler angle should not be 90 degrees.
The only consquence that I can think of is that perhapes some rotation cannot be achieved if the 3 axis rotation order(ex. x->y->z) have been decided? I'm not sure this is the case, please help me out!
