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))`. + +--- + +⚠️ Try this out by extending the example of the main doc, so that a new teleporting fish with random positions [-50, 50] is generated.
