This paper proposes an interactive robot with entertainment application for a connect four game. The proposed interactive robot contains the main body of the robot mechanism, the servo motor module, the light sensor module, the touch switch module, the text-to-speech module, the servo card and the core board. The main body contains an XY stage to scan the colored disks position which the users put and a putting colored disk institution can be used for the action of the game artificial intelligence. Servo motor module is used to control the position of DC servo motor and light sensor modules to detect the board information. Through the user pressing the touch switch module, it indicates that the user has completed the colored disks action, and it is the robot turn to play colored disks. In the core board selection, this paper takes the advantages of high performance, low price of ARM Cortex-M3 microcontroller (LM3S1138) to be the whole core of the operation. The experimental results of the paper show that the proposed interactive robot can reach the goal to enhance entertainment.
