Hi all, I currently need to use the rotation velocity measurements from an object rotating over all axis (think rotating in space), however whenever I try obtaining the truth data from a transform sensor for rotational velocity, I get values that are not at all constant. This is despite no external forces acting on the object.
For example if I had a long prism with the dimensions [.1 1 1] separated from the world frame with a 6dof block which is then given initial conditions of spherical primitive velocity values [-.1 .2 .3], the resulting scope outputs a graph with values that are not at all constant. This is where I am confused, because according to my best understanding a rotation around the center of gravity will remain constant.
Pictures of a rough layout below.
Would anyone be able to explain why the rotation is not constant?
