An educational gaming system includes control cards, road pieces and a robotic device. Each of the control cards has a graphic corresponding to an instruction. The road pieces are arranged to form a road on which the robotic device is configured to move. The robotic device is communicable with an electronic device that executes an application program. The electronic device captures an image of the graphic of the control card, conducts a machine learning algorithm based on the image to obtain the instruction, and transmits the instruction to the robotic device. The robotic device obtains a road-piece signal value that is generated by scanning one of the road pieces, and performs movement based on the instruction and the road-piece signal value.
