Abstract
A robot cleaner capable of moving in diverse directions and enhancing cleaning efficiency by increasing frictional force between a pad and a floor includes two or more driving units. Each of the driving units includes plural motors, a first subframe connected to at least any one of the motors and configured to rotate by receiving rotational force from the motor, a rotating plate assembly mounted to the first subframe and configured to be slanted with respect to a floor by rotation of the first subframe and to rotate clockwise or counterclockwise by receiving rotational force from another motor, and a pad provided at the rotating plate assembly and configured to contact the floor. When the rotating plate assembly is slanted with respect to the floor, nonuniform frictional force is generated between the pad and the floor, through which the robot cleaner travels.
