-### Calculated orientations and speeds.
-
-
-
-The image shows, how the orientations are calculated (`robofish.io.entity.Entity.poses_calc_ori_rad`), the orientations always show away from the last position. In this way, the first position does not have an orientation and the shape of the resulting array is `(timesteps - 1, 3 (x, y, calc_ori_rad))`.
-
-The meaning of the `robofish.io.entity.Entity.speed_turn` can also be explained with the image. The turn is the angle, the agent has to turn, to orientate towards the next position. The speed is the calculated, using the distance between two positions. The resulting turn and speed is converted to `[rad/s]` and `[cm/s]`. The first and last position don't have any action which results in an array shape of `(timesteps - 2, 2 (speed, turn))`.
