1. A system for calibrating a gyrosensor of a mobile robot, the system comprising:

  • a camera to obtain image data of a fixed environment;

    a rotation angle calculation unit to calculate a plurality of angular velocities of the mobile robot based on an analysis of the image data;

    the gyrosensor to output a plurality of pieces of raw data according to rotation inertia of the mobile robot; and

    a scale factor calculation unit to calculate a scale factor that indicates the relationship between the pieces of raw data and the angular velocities.
