ROBOT CLEANER
First Claim
1. A robot cleaner comprising:
- a pad assembly connected to a first motor to receive a rotational force from the motor and configured to rotate in a clockwise or counterclockwise direction to clean a floor surface; and
a first wire connected to the pad assembly and a second motor so that the pad assembly is tilted by the driving force of the second motor,wherein the robot cleaner moves in a particular direction by a non-uniform frictional force between a bottom surface of the pad assembly and the floor surface.

Abstract
A robot cleaner includes a plurality of motors each of which transmits a driving force, a pad assembly which is connected to one of the plurality of motors to receive a rotational force from the motor, to rotate in a clockwise or counterclockwise direction, and thus to clean a floor surface, and a wire which is connected to the pad assembly and another one of the plurality of motors so that the pad assembly is tilted by the driving force of the motor, wherein the robot cleaner moves in a particular direction by a non-uniform frictional force between a bottom surface of the pad assembly and the floor surface. The robot cleaner uses wires to tilt the pad assembly and, thus, it is possible to miniaturize the robot cleaner.

16. A robot cleaner comprising:
-
a pad assembly installed at a base and having a pad installed at a bottom surface thereof; a third motor and a second motor which are provided at the base; a first motor connected with the pad assembly to rotate the pad assembly in a clockwise or counterclockwise direction; a first wire connected with the pad assembly and the second motor to tilt the pad assembly with respect to an x-axis; and a second wire connected with the pad assembly and the third motor to tilt the pad assembly with respect to a y-axis, wherein, when the pad assembly is tilted by the first wire or the second wire, the robot cleaner moves in a particular direction by a non-uniform frictional force between the bottom surface of the pad assembly and a floor surface. - View Dependent Claims (17, 18, 19, 20)

24. A robot cleaner comprising:
-
a pad assembly comprising a rotational plate rotated in a clockwise or a counterclockwise direction by a first motor to clean a floor surface; a water supplying member installed at the rotational plate, the water supplying member comprising a central hole in communication with a water tank and a side hole formed at a side surface thereof to be in communication with the central hole; a first wire connected to the pad assembly and a second motor so that the pad assembly is tilted by the driving force of the second motor, wherein the robot cleaner moves in a particular direction by a non-uniform frictional force between a bottom surface of the pad assembly and the floor surface.
