1. A cleaning robot comprising:
- a fixed body;
a traveling part provided at a lower portion of the fixed body to enable the cleaning robot to move along a floor surface;
a suction part provided at the fixed body to suck foreign materials from the floor surface;
a cover surrounding the fixed body, the cover being configured to receive an external force;
a movement frame supporting the cover, the movement frame being movable horizontally with respect to the fixed body;
at least one elasticity setting part provided between the movement frame and the fixed body to support the movement frame relative to the fixed body, and to permit limited movement of the cover with respect to the fixed body; and
a sensor configured to sense movement of the movement frame.

20. A cleaning robot comprising:
-
a fixed body; a plurality of wheels provided at a lower portion of the fixed body to enable the cleaning robot to move along a floor surface; a suction part provided at the fixed body to suck foreign materials from the floor surface; a cover surrounding the fixed body, the cover being configured to receive an external force; a movement frame supporting the cover, the movement frame being movable horizontally with respect to the fixed body; at least one elasticity setting part provided between the movement frame and the fixed body to support the movement frame relative to the fixed body, and to permit limited movement of the cover with respect to the fixed body, the at least one elasticity setting part comprising; a plate provided on the fixed body; an inner body contacting an upper surface of the plate; a movement shaft connecting the movement frame to the inner body; a first elastic member connected between the movement frame and the fixed body for biasing the movement frame in a first direction; and a second elastic member connected between the movement frame and the fixed body for biasing the movement frame in a second direction; a sensor configured to sense movement of the movement frame; and a controller configured to recognize that the external force is applied to the cover based on a sensed result of the sensor, wherein the controller controls the plurality of wheels to change traveling properties of the cleaning robot when the external force is applied.
