# Fixed BallBalancer Simulation problem

- First I changed the starting position of the ball, so it is not starting in the plane anymore.
- For the "staying on the plane" problem the angle a had to be negated (I still don't know why exactly, but this makes the plane work appropriate) and the angles a and b had to be switched in the ball position animation. This solved the problem and the ball is now constantly on the plane (at least with the init_states I tested).
