In this paper, we design a two-wheeled mobile robot which could be control by Android mobile phone. The way that controlling robot through Android software is easy and convenient for people to use; while the two-wheeled mobile robot owns the characteristics of adaptation and flexibility. As a platform, this robot can accomplish a series of functions by combining it with different additional modules. Therefore, this robot has significant spreading value and promising application future. As for the principle of controlling the robot: by adjusting the direction of rotation of two isolating electric motor, we can keep its balance. By changing the dip of the robot, in other words, changing the speed of rotation of electric motor, we can determine the speed of the robot. Through controlling the difference of the speed between two electric motors, we can adjust the direction of the robot. All controlling depends on the feedback provided by optical encoder, gyroscope and accelerometer. As for human-computer interaction, we accomplish human-computer communication on the basis of Bluetooth, and we design an Android software used for direct the robot. Through experiment, we confirmed that the robot can keep balance itself, and can be controlled to move in a specific direction by our Android software. In the end, through establishing small-scale holographic projection equipment on the robot, we discuss the prospect of it.
