The Design of a Two-wheeled Mobile Platform with Face Following Functionality

This study designs a two-wheeled mobile platform with autonomous movement and face following functionality. The autonomous movement mechanism uses the change of the center of gravity to make the two-wheeled mobile platform move forward or backward, and utilizes simultaneously the PID controller to keep its balance. The face following functionality uses a tablet with an image sensor and an image processing to perform face recognition, and finds a tracking direction. Experimental results show that the two-wheeled mobile platform can perform autonomous balance, the movement and face tracking functionality.
