Euler Angles jumping from 0 to 180/-180

Post by xman237 »

Hi all,

my euler angles (alpha and gamma) are jumping from 0 to 180/-180 (see, https://imgur.com/a/aAPtRN3) , while beta is showing stable outputs. Is there a way to prevent this?

Hello and sorry for the late reply,

this is perfectly normal with Euler angles: CoppeliaSim uses Rx*Ry*Rz rotations. In that case alpha and gamma will jump at the +-180 degree extremities, and beta will jump at the +-90 degree extremities. Those values are cyclic.

Cheers
