56 +* Flashing lights need to be masked or excluded by means of color to prevent misdetections
57 +* The pixel coordinates should be translated to a custom coordinate system, s.t. chnages in resolution or exact camera position can be abstracted from

63 +* For now the physics model passes a single number, the time the ball is predicted to be in range, i.e. when to trigger the flippers.
64 +For the logic to be able to perform meaningful computation more information needs to be passed, e.g.:
65 +** **Position** the ball is predicted to be at at the corresponding time
66 +** **Velocity **vector of the ball
67 +* Gravity on (% lang="en" %)inclined plane

69 +* (% lang="en" %)Different ball behavior when rolling down the inlanes
