1. A cleaning robot comprising:
- a robot main body comprising a driving unit to drive the cleaning robot, and a cleaning unit to remove dust;
a bumper unit which is movably mounted in the robot main body to protect the robot main body from a collision with an obstacle;
a sensor unit which supports the bumper unit movably in a plurality of directions including a linear direction and a rotary direction to sense the collision of the bumper unit and the obstacle wherein the sensor unit comprises a supporting member and a sensor which senses movement of the supporting member, wherein the supporting member has a first end that supports the bumper member and a second end that is rotatably inserted into a supporting member holder, the supporting member holder being provided in the robot main body; and
a control unit which controls the driving unit on the basis of a signal sensed by the sensor unit to avoid the obstacle.

15. A cleaning robot comprising:
-
a robot main body having a driving unit to drive the cleaning robot and a cleaning unit to remove dust from a surface; a bumper unit to protect the robot main body from a collision with an obstacle; a sensor in the robot main body that supports the bumper unit so that the bumper unit protrudes from an exterior surface of the robot main body and moves in both a linear direction and a rotary direction, the sensor senses the collision of the bumper unit with the obstacle, wherein the sensor unit comprises a supporting member and a sensor which senses movement of the supporting member, wherein the supporting member has a first end that supports the bumper member and a second end that is rotatably inserted into a supporting member holder, the supporting member holder being provided in the robot main body; and a control unit which controls both the driving unit and the cleaning unit on the basis of a signal sensed by the sensor unit.
