ROBOT CLEANER AND METHOD OF OPERATING THE SAME
First Claim
1. A robot cleaner comprising:
- a main body;
a traveling unit to allow the main body to travel;
a cleaning unit to suction foreign substances around the main body during the traveling;
a sensor unit that is rotatable to sense an obstacle using light reflected or scattered by the obstacle; and
a controller to control the traveling unit so as to travel along a traveling path and to control the cleaning unit so as to perform cleaning,wherein the sensor unit comprises a first mode and a second mode that are set to differ from each other in sensitivity with respect to the reflected or scattered light, and the controller changes the sensitivity of the sensor unit according to a traveling mode.

Abstract
A robot cleaner includes a main body, a traveling unit, a cleaning unit, a sensor unit, and a controller. The traveling unit allows the main body to travel. The cleaning unit suctions foreign substances around the main body during the traveling. The sensor unit is rotatable and senses an obstacle using light reflected or scattered by the obstacle. The controller controls the traveling unit so as to travel along a traveling path and controls the cleaning unit so as to perform cleaning. Here, the sensor unit includes a first mode and a second mode that are set to differ from each other in sensitivity with respect to the reflected or scattered light, and the controller changes the sensitivity of the sensor unit according to a traveling mode.

13. A method of operating a robot cleaner, comprising:
-
setting a traveling mode by a controller; setting one of a first mode and a second mode having different sensitivities for incident light in a rotatable sensor unit by the controller to sense an obstacle using the incident light reflected or scattered by the obstacle; and setting by the controller, upon traveling, the sensitivity of the sensor unit to the first mode to travel to a target point to avoid the obstacle sensed by the sensor unit. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
