ABSTRACT:
Disclosed is a driving apparatus for a robot cleaner enabling drive wheels to be in contact with a floor all the time. The driving apparatus for a robot cleaner includes a robot cleaner main body, driving motors mounted in the robot cleaner main body, and for transferring power to drive wheels, driving motor housings hinged with the robot cleaner main body, and for accommodating the driving motors therein, and pressure members disposed between the robot cleaner main body and the driving motor housings, and for pressing the driving motor housings. Accordingly, the driving motor housings are mounted to rotate about the center of the rotation hinges so that the drive wheels come in contact with the floor all the time, preventing the drive wheels from being lifted over the floor and making lost rotations due to curved portions of the floor or obstacles.
