This thesis focuses on the innovation of the hardware and software solution of the robotic table football by B&R. The main objective was to eliminate the shortcomings of the initial solution, which limited both the fluency and accuracy of the game. To improve ball detection, uniform lighting of the playing surface was ensured, and an interface for adjusting the camera's exposure time was created. Additionally, an interface for easy camera image calibration was implemented. When the ball is not visible, a newly designed algorithm is utilized to predict its position. Furthermore, the frame rate was increased from 60 to 100 frames per second due to more efficient camera triggering. In the area of drives, a new motor control method was implemented, enabling precise movement timing of both the rotational and linear axes. As a result, a set of new, more precise motion commands was created. These motion commands are utilized within a newly developed gameplay strategy. According to this strategy, each game axis switches between an offensive and a defensive mode. The defensive mode, referred to as shadow defense, positions the puppets to block the ball's path to the robot's goal as effectively as possible. The modifications eliminated game stalling, reduced the reaction time of the game axes, accelerated their movement, and improved the precision of the kicks.
